Does anyone have experience with OPA380 ?

Message-ID: <1141255746.14229.34.camel@localhost.localhost>

some updates again on the rs232 interface and co.

like sigfried suggested i thought about modulation again.
pulse-width modulation might be a good solution to avoid wrong
interpreted noise without transmision data. (dont know if its pulse
with-  burst- or frequency-modulation what i'm doing.)
i'v already ordered the required parts  with a few extras to experiment
around.

i finnaly got a complete datasheet with diagrams for the bf908 in the
receiver and now it makes a lot of sense! .bf964/966 should give little
more gain with little less noise (according to the datasheets)
so sorry for all my posts asking how it could work. great solution=)
most likely i will use the same thing with slight modifications.

with the redesign of the receiver and transmitter i hope to get more
range more than 3 meters without optic. and since pulsewith modulation
and demodulation is easy to do it will most likely go into the final
circuit. should also give a good extra in range since there is no
"empty-signal".
carrier signal will be 10 mhz transmission frequence, "no" signal will
be 5mhz;
demodualted by simply counting and resetting the counter with a 1mhz
signal.
the information signal will be around 200khz or below.
maybe that i already need a even higher carrier frequency. have to test
that.
.maybe a more eficient way with simple syncronising could increase
data-rate without increasing carrier frequency (more real pulse-with
modulation) will think about it since it might be very necessary (would
lessen pulse-with error in the received signal - atm there should be a
max. of ~+-20% @192kbit datarate-less error with less datarate)

no real sollution for the existing ronja because of the transmittion
led's would be too slow for such datarates AND modulation.

also found a 6$ usb->rs232/rs4** converter chip with drivers available
for all windows and linux with kernel2.4 or later (not shure about
mac)-gives you a virtual com port to set up a null-modem connection.
i think the chip can handle 3mbit with ttl compatible output.
-might be intresting, too.

suggestions are always welcome.
@sigi:"seems near to the end.things are going fine. maybe only a few
weeks left till release. pcb-layouts most likely included=)"

The trunking is used for the Ronja wireless systems, the other
connections are usually done with wires but not necessarily.

With the exception that you have to force switches and network cards
into full duplex to get decent performance, there is no difference to
wired ethernet.

There is no single part inside that makes the thing expensive. Every

Yes. But use infrared for this because currently the transmitter may
burn the LED if it gets an invalid signal on the input, which happens
during fog. It doesn't burn only if it gets no signal. I am planning to
fix this bug.

Proto jsem to udelal tak jak jsem to udelal, aby se s tim dalo komunikovat 
normalne lidsky, merilo to dobre a hlavne, aby se dalo podle toho zamerovat.

hey thnx for the anwsers.(although a liiiitle late ;) but thats no
problem)

in the meantime i learnd a lot. thanxs to you, other guys @ this mailing
list, the whole ronja project and of course the rest of the www.
bdw.. above i meant to write 1mhz not 1ghz ;) typo.

i thought about letting the transmitter "glow" so you can see if
everything is fine and transmit with full power.
should work fine, or at leat i hope so. don't know it it would work for
10mbit,too since i'm still using rs232 interface.

since i'm writing: have you tried adding a simple back-cuppeld npn
(maybe low-noise one) transistor in emiter-wiring as a 2nd amp stage

for the rs232 version: stay tuned- i finaly got some optic.  2x 42mm
lenses.
ah- and i forgot to say. i havent read it anywhere but i have the
feeling that : smaller transmitter-led diameter -> better
beam-quality&less beam divergence. with my 5mm led the beam grows 1,5cm
diameter per meter beam-length. with a 100m connection already 1,5m beam
width.. not very good. is this normal?

and a hint for long-distance optic:
-since my lenses where taken out of a binocular i added 1 smaler lens
between transmitter-led and transmitter lens. result was beam with a
constantly beam-diameter even after 3 m (most of my room) the beam
wasn't blury or anyting, just a nice-red and bright.and only a few mm
more than transmitter lens diameter. requires better aiming but another
grat signal gain=)

my best greetings to everyone, and keep improving things :)

The signal chain is designed for 1MHz-10MHz band with an attempt to
exclude other frequencies as much as possible.

Schmitt trigger won't help at all against burning the LED. The problem
is signal with undefined duty cycle at the input. It will be solved by
LED current feedback regulation from Nebulus. Schmitt trigger will be
used only to prevent oscillations of the transmitter without signal.

i thought about using the glow for your transmitter to protect led from
bruning "high" all the thime(more or less inverting it to be off without
signal-only a little glow left). that my rs232 version wont work with
10mhz and onther way round goes without saying.

you really should.grab a suitable npn and the rest is very
textbook-like. 10kOhm from collector to base, 1kOhm between colector and
Vcc (at 5v- with 12 might need a little more ohm)- in put with
capaicitor connected to the base, emiter to ground and between collector
resistor and collector you shlould grab the signal.
if you cant find a fast enough npn for emiter. maybe a base-based
amp-stage is more suitable (wost of them they work at >100mhz without
problems(or should))

what i meant was. use shmittriggers on the "receiver side" instead of
emtpy-signal on the "transmitter(or twister) side".
burning the led was not what i was talking about in this part (maybe i
should really start to add sub-headlines)

hm, what led-diameter are you using?.. well if i think about. higher
focal length could increase quality.my focal lenght is about 20cm.
5mm led diameter and 40mm lens diameter.
or your lenses distort the light in a good way :D
and are your beam-edges still sharp at 260m or are they blury?(just
asking to get an idea why i have such problems with only one lens)

can someone explain, what exactly
is the situation, when the LED in TX-Twister can burn ?

Subject: [Ronja] Fun: how to make people read the Ronja guide
Message-ID: <20060311194721.GA24067@kestrel>

People don't read Ronja guide much, that's a fact, judging from how many
important steps they are skipping and then sending me a report that it
doesn't work.

That's a problem in all technical docs and doesn't matter if read by
a skilled or a n00b - they are boring, that's it. I thought this problem
cannot be overcome but Burton managed to figure it out.

When I installed my Burton bindings I had to read all the text in the
leaflet and the box because I couldn't help myself. There are things
like:

"LEASH use this to walk your ferret. Or to keep your board from charging
down the hill and maiming somebody. Put the metal end into the bottom of
the baseplate and then clip the other end to your earring. Just kidding.
Clip it to your boot. Safety first."

Or

"TIGHTENING SCREWS if your binding screws are not tight, your bindings
are gonna fall off and you are going to break your ass."

The box says:
"WARNING Look both ways before you cross the street. Bathtubs are
slippery. Don't stand on the top step of a ladder. Life has
risks...snowboarding is one of them.[...]"

We need to put things like this into the Ronja guide because then people
will read it from A to Z and they will not skip things and their Ronja
will work right.

Please everyone, especially those who are in puberty, send things like
this. Either patches to the guide text or comic strips preferrably in
SVG format. Like this, but not based on copyrighted one:

Because the duty cycle of the signal going into the LED increases
over 50%.

HPWT-BD00-E4000 or HPWT-BD000-E4000. I don't know exactly the diameter
but it's I think around 3.1mm. You can look it up in the datasheet.

Hi,

I'm making RONJA as my college project as well as for personal use. As
an electronics student, the project is of great interest to me because
of its amazing performance at such low cost.

I have some doubts that I hope someone can clarify for me. To be clear,
I was looking at the Twister as well the Spider designs for the signal
conditioning part of the project.

1) Why does the spider use the LAN filter module while Twister doesn't?
I have seen it on LAN NICs and am wondering what it is used for.
2) Is there any alternatives to the dual gate MOSFET in the RX section
(other than the given substitues)? It is impossible get these in India
and it costs humongous amounts to import them. I'm wondering about any
IC's that can do the job. Suggestions?
3) Its hopeless trying to find those LEDs for the TX. I'm wondering how
effective a rigged up solution using multiple super-bright 5mm red LEDs
would be (clear dome). Thoughts? (I'm willing to wait for someone to
send it to me from CZ (from the contacts in the Wiki, I've contacted one
of them) for personal use. But my project for uni is due very soon and I
can't wait for that. I only need to demonstrate it working in 100m range
or so for uni - hence the thought of using multiple 5mm dome LEDs).

Thanks in advance for any replies.

Regards,
Arun Krishnan

if you can make a normal npn workin with >20mhz you might be able to
replace the thing with a normal 1-transistor amp-stage (maybe not
emitter but base-wiring). haven't tested it but it should do the same
job, might add more noise to the received signal than a mosfet but MIGHT
be worth a try.

could work the same way as a single bright led. but you need to fiddle
around with the optic or you won't be able to focus the light on one
spot. guess if you find a optical solution 100m MIGHT be possible

just my thoughts...

if you need 2 or 3 of those mosfet i still have some left.
could send you ~5 BF964 as soon as tomorrow ,don't need them anymore
(spare parts). dont have any good led's myself- sry.

Try to disassemble an old TV. The antenna input goes directly into a
tuner and the tuner usually contains it at the input. Not completely
old, but say one from eighties or seventies.

Or try to order it from someone who sells it online.

Ineffective. Order the right led from some people on the mailing list.

If someone on the uni has third brake light in his car then ask him if
he can lend you one diode from inside. He has plenty of others left so
he shouldn't mind ;-) Or order from someone on the list. They fit into
an envelope and don't take long to send, even abroad.

I started this topic cca month ago. You have to build another amplifier, 
beacuse the transceivers output is not strong enough. Then it is feaseable.

if reciever is ok, then maybe I can put ronja TX on each end? Or 
reciever also is not ok?

I didn't try this.  Fibre optic transceivers are not designed with a
weak scintillating signal in mind. Also there is no need to make it
sunlight resistant.

Zdravim, docela by me zajimalo, zda by se dala tahle LED pouzit do Tx, treba i po nejakych upravach
L-LXHL-BD01 s parametry:
red 625nm
uhel 110?
svetelny tok 27lm
udavany opticky vykon 1W 
I kdyz vezmem v uvahu rozdil vlnovych delek - 625 a 635nm, ktery se projevi ve fotometrickych velicinach - sv. tok a svitivost, porad mam dojem, ze ten Luxeon je mnohem vykonejsi (stoji taky cca 280,-). 
Zere nejakych 350mA pri U=2.3-3.3V, byl by tohle problem?

Predem dik za jakykoliv komentare, Michal.

LUXEON je pomaly, tusim pomalejsi jeste vic nez infra LEDka, myslim, ze tu
na mail listu probehla dokonce informace, ze Clock upravuje vysilac i pro
Luxeon. No, potom, co prohlasil, ze ve vysilaci je chyba a ze ho predela

No, probiralo se to tu tusim kvuli retlanslaci (prijimac rovnou do vysilace)
a zminoval se, ze jsou s tim nejake problemy kvuli spatnemu navrhu. Melo by
to byt nekde v historii, ale nemam silu to prochazet.

Cau, momentalne s tim experimentuju, ale jenom te chci upozornit ze 1W neni 
radiated power P=U*I=0.35*3=1W , je to prikon, radiated power bude tak 
100-200mW. Jo a ohledne te rychlosti, ptal jsem se vyrobce a udajny rise 
time je 15ns, takze problem bude spise s dostatecne vykonnym driverem 
protoze to chce tak 700-800mA pulzne.

To All:
Zdravim,
nekolikrat uz to tady probehlo ale stejne to pro jistotu zminim.
Pokud mate v planu predelat navrh TX casti, doporucoval bych pouzit 
tranzistory
po buzeni ledky a nastavit je tak, aby uroven vypnuto udrzovala na ledce 
napeti
tesne na V-treshhold, nejsem si jisty, ale rekl bych ze pod touto urovni se 
u vykonnych
led projevuje znacna kapacita ktera zrejme znacne snizuje rychlost sepnuti. 
Pokud
o tom nekdo neco vite a pletu se, tak me prosim opravte, nemam k dispozici 
osciloskop
takze si to nemuzu moc overit.

Yes this would be a problem the transmitter is not designed for a
Luxeon.

Ten uhel 110? je zabijak, pak to pri neumerne slozitejsi konstrukci a prikonu
chodi s beznyma lupama jen o fous lip nez se s diodama HPWT-BDabcd. Rozumne se
to chovalo kdyz jsem dal dve 130mm cocky za sebe, jenze zase to utesnit aby se
mezi nima nekondezovala voda je ukol nadlidsky.
Pak se jeste necha koupit luxeon s optikou s vystupnim uhlem 10? a 30?. Jenze ty
plastove cocky jsou zase tak "nekvalitni" ze si stejne nepomuzem.
Jedine rozumne pouziti bylo kdyz jsem luxeon soupnul do stareho meotaru. Ale na
nejakou extra vzdalenost to zase neni kvuli vadam freschnelky v tom meotaru.

Jo zrovna delam domaci ukol "navrh twisteru2" :) Protoze si nekdo
stezoval ze to rusi televizi a analyza ukazala, ze to je to systemova
chyba. 

Aspon odpadne 19 sroubku, 27 maticek, 9 podlozek, 1 svorkovnice, asi 10
der, zhruba 8 dratku a 10 konektoru, krabicka se zmensi, zmensi se pocet
vyvodu co se musej strkat do direk, nebude se to muset tlemit tepelnou
pistulkou. Proste takovej jarni uklid ;-)

Jo, a) rusi to telku, b) kdyz je to bez signalu a osazeny AC hradlama
tak se to rozkmita, c) kdyz to dostane neplatnej signal z prijimace bez
signalu, tak to provari diodu.

Taky je to zbytecne velky a osklivy :)

V normalnim pouziti pro normalni lidi to nijak nevadi. Retranslaci ma
zatim stejne jedinej clovek v Beharovicich. A s HC hradlama, ktery se do
toho podle navodu osazujou to bez signalu nekmita. A vetsina lidi to u
anteny od televize stejne nema.

Co jsem se ptal kolegy v praci tak ten rikal ze FCC B znamena zhruba
stovky mV ruseni na napajecich vodicich a FCC A zhruba desitky - ja tam
mam 10mV a delam z toho udalost. Rad bych to stlacil na 1mV (nejsem
zadna komerce a nemam za zadkem zadny akcionare ktery by me nutili abych
misto toho abych to udelal poradne rikal lidem ze si maj pootocit
televizi a antenu).

Ten uhel 110? je zabijak, pak to pri neumerne slozitejsi konstrukci a

Pak se jeste necha koupit luxeon s optikou s vystupnim uhlem 10? a 30?. 
Jenze ty

Jedine rozumne pouziti bylo kdyz jsem luxeon soupnul do stareho meotaru. Ale

nejakou extra vzdalenost to zase neni kvuli vadam freschnelky v tom meotaru.

oki, je to na Karlaku, u zastavky tramvaje Moran, Vaclavska Pasaz ve smeru
od namesti po prave strane je maly bazar s elektronikou (pozor je tam jeste
prodejna soucastek Compo, tak ta ne, navic je zbesile predrazena). Ja jsem
konkretne kupoval 90mm lupy za 70,-, sklo je ciste a neposkrabane jenom
musite davat pozor pri vyndavani, skla jsou v obroucce zalita, ja jsem je 
narizl
pilkou na zelezo a pak roztrhl:-)

Zdravim,
mam takovy dotaz, vi nekdo o HW routeru za rozumnou cenu, ktery by mel 2WAN 
pripojeni pro RONJU a WiFi 802.11a (5GHz) mezi kterymi by v pripade vypadku 
Ronji umel rychle prepnout a alespon 4LAN pripojeni, mel NAT, firewall 
nastavitelny zvlast pro kazdy lan port, spravu po webu nebo usb/rs232 to je 
jedno, a hlavne aby mel traffic shaping? nasel jsem docela levne kousky 
ktere maji vse az na traffic shaping a firewall zvlast pro kazdy port:-(
Predem diky za tipy.

S uspechem pouzivam Linksys WRT54GL. Ma celkem 5 portu, a pomoci skriptu 
jde kazdy port prenastavit na solo sitovou kartu , jde mu nastavovat 
FD/HD 100/10mbit a i nastaveni Cross to umi.

Aby ti to automaticky prepinalo na zalohu si do nej instalnes Quaggu. 
Shaper si muzes do toho napsat a na firewall pouzijes iptables. Chce to 
mit, ale uz lepsi znalosti linuxu.

Diky za tip,
ted mi to bezi na slackwaru na PCcku, jakztakz jsem to splacal a 
nakofiguroval sam,
jestli ten linux v routeru nebude moc odlisny(nemusel by byt:-), tak to snad 
zvladnu,
necekal jsem ze pod 3000,-s dph lze koupit hw s linuxem:-) akorat jeste 
dotaz, nevznikaji
tam v dusledku pomalejsiho cpu prodlevy pri shapingu?
jo a ted koukam ze je jenom 802.11b/g, ja potrebuju 802.11a:-((

Myslim, ze mnaga ma pravdu, s tim napajenim a zemi.
Sice to bude znamenat nekompatibilitu se starymi, ale za cenu
nekolikanasobne lepsich vlastnosti.

Pozor na crap - spousta routeru ma sice libivou barevnou krabicku se
spoustou naslibovanych featur, ale pri provozu nahodne tuhne.

No nevim - kdyz se to korektne zablokuje tak napajeni nerusi.

Jeste jsem nevidel aby to blblo kuli stineni koaxu. To uzemneni nahore
je kazdopadne potreba kvuli blesku, jinak to zarizeni predstavuje
pozarni nebezpeci (a jeste to muze zabit cloveka co sedi u pocitace).
Takze jestli mas pripad kdy to blbne a nevyresi se to Twisterem2,
tak budu muset dat do specifikace nejaky minimalni pozadavky na stineni.

Ale ja jsem to tahal audio dvoulinkou 30m co stineni mela jen takovy
stoceny svazek dratku, ani zadny pleteni, a zadny problemy jsem
nepozoroval. Neprovadel jsi nejake zmeny do elektroniky co by to mohly
zpusobit?

Obcas to byva jen chyba software - napriklad chip v oblibenem
Ovislinku WL-1120 ma integrovany watchdog, akorat dodavany
firmware ho (nejspis) nepouziva. Pokud se vsak dodavany firmware
nahradni vlastnim Linuxem s driverem prislusneho watchdogu, tak
jiz problem s tuhnutim neni.

Jako moznou odpoved na puvodni dotaz me napada klasicky ASUS WL-500b, kde
je mozne vymenit integrovanou miniPCI sitovku za Atheros a jsou dobre
vypracovane postupy jak na to nainstalovat Linux.

Jako dalsi moznosti me napadaji WRAP nebo Routerboard - na oboje je mozne
nainstalovat Linux vlozit miniPCI Atherose, maji vic ethernetovych rozhrani a
integrovany watchdog. K nim by bylo treba pripojit bezny switch. Ale je to
ponekd drazsi reseni.

Jenze je problem to ucinne zablokovat. Ale stejne nejvic me prudil ten
propojovaci kablik mezi TX a RX. Kdyz tam neni tak instalace ci vymena
kterekoliv roury je temer sekundova zalezitost. Navic tim UTPckem si posilam
dolu ke kompu napeti rssi.

Dotycny pachatel tam mel TV koax typu pohlinikovana PE folie a dratecek. Kdyz
tim tece skoro amper tak se deje. A kdyz se v historickem dvojvodicovem rozvodu
v cinzaku nekde povoli v zasuvkach PEN, tak to se teprve dejou veci.
Sice podle normy ma byt spojena pata hromosvodu s hlavni zemnici svorkovnici
"hodin" ale kdo to kdy videl ve starsi zastavbe? Pak staci bludne proudy co
treba vyrabi tramvaj a je veselo.
Muj nazor je uzemnit twister a nahore v trubkach spojit elektroniku s uzemnenou
konstrukci pres varistor nebo bleskojistku.

 Diky za tip,
nevis jestli to plati i pro Asus WL-520g (2300,-) nebo WL-300g(2800,-)?

 Ta atheroska stoji 1100-1200,-, ma nekdo zkusenost jestli bezi i v PCI 
2.0,2.1,2.2?
trosku me desi ze vyrobce vyzaduje PCI2.3, protoze jsem ji chtel pouzit v 
AMD K6-2/350
jejiz deska ma PCI 2.1(mam pocit), adapter miniPCI-PCI stoji 400,-, coz je 
dohromady 1600,-
oproti 2800,- za nejlevnejsi PCI 5GHz kartu kterou jsem nasel.
predem diky za info a zkusenosti

Atheros CM9 nechodi v pasivnich redukcich ve starsich PCI sbernicich. Bud
sehnat redukci s napetovym stabilizatorem (napr. RB14 4 miniPCI do 1 PCI),
nebo napriklad kartu VZA-81 - integrovana CM9 s PCI redukci, napetovym
stabilizatorem a pigtailem.

VZA-81 se da sehnat do cca 1700,-

Podle prispevku to chapu tak, ze uz ti s tim Ronja chvili (nejak) fungovala, mohl bys napsat (prip prilozit nakres) jak jsi upravoval Tx aby dokazalo tuhle diodu nakrmit? 
Rad bych to zkusil s tema dvema cockama - nejakou mensi (60mm) pred diodu a dopredu klasicky 130mm, konstrukcne to zas takova drbacka nemusi byt, mam totiz Rx i Tx vyrobeny doslova jako spunty zaveseny na zavitove tyci - krabicky jsou sevreny zepredu a zezadu koleckama z plexiskla, ze zadniho jde zavitova tyc ktera prochazi pres gum. pruchodku vikem, zvenku je maticka, kterou muzu jemne menit pozici modulu vuci cocce. Ma to vyhodu v lepsim tesneni (maly pocet der) a lepsim nastavovani. Tu dalsi cocku bych proste dal jako "predsadku" na predni  kolecko.

Je to texas instruments, jak napovida nazev je to derivat 74xx244, ta 25 
znamena ze je navrzen pro 25ohm linky, kazdy buffer uzemni 180mA, (rise/fall 
time) + propagation delay je 3.2/4 ns :-)
stoji okolo 7$/pc pri tisici kusech primo od TI bez dane,dopravy a cla:-)

Napajeni po koaxu je smrt.
Pristi verze spidera bude mit taky RJ konektor (obrovska vyhoda je v 
krimpovani kabelu vs pajeni).

Co tam je za atmela? Mozna bych to naprogramoval. Jestli tam je 51 tak to 
nevim jestli se mi chce, uz se knim moc nechci vracet.
Jestli je tam avrko, tak to napisu rad.

I'm looking for people who thought about changing a CD-RW into a IR
Sender/Receiver.

If you are aware about any thoughts about this issue, please share it with me.

Thank you, Thomas Kalka

Hehe, 51 ten realtek nenakrmis ani omylem. Z toho se da vymacknout tak 80
KB/sec, coz bude trochu malo.
Plnohodnotne rozhranni se da udelat, kdyz se tam prida trafo.
Obejit se to da pouzitim levneho switche s HW prepnutim jednoho portu do
10Mbps FD.

No nekdo dokonce psal tusim 75 metru.
Ja osobne tam dam hned ten upraveny switch a pak si to muzu natahnout az
tech 105 metru.
Akorat to uz vyrabim nekolikaty rok :-(

Hi Thomas, hi Everyone!

I am experimenting with the converting of laser diode systems into a
usable TX.

Sadly I had a huge HDD crash and all my data got lost. I am working on
getting them back, but it will take time.

So what are the pros? :
- point-like source, which you can almost perfectly collimate also with
cheap optics,
- very fast switching time, that could give a benefit to the existing
Ronja design, because of less jitter etc., and could also enable
100MBit/s...1Gbit/s operation for new designs, but that's a long way to
go...
- DVD or CD- burners have LD-s of an optical power up to 200mW.
- if you can manage to use the Pick-Up with its APC and its Modulation
capabilities, it is very easy to control the LD via the burning channels
of the APC.
- almost perfect optical parts, already assembled together into a
Pick-Up-Head make it easy to assemble the whole transmitter.
- good cooling for the LD on the Pick-Up
- modulation is more linear than LED

What are the conts? :
- to operate a LD stable, and not to fry it, you MUST use an APC
(automatic power control) cuircuit, that is monitoring the optical
output, and also able to protect the LD when the voltage is shut down or
on. (spike-free operation)
- you have to take care to adjust the OPTICAL light power output not to
exceed the absolute maximum during modulation.
- LD-s are extremely sensitive to electrostatic charges, so it is not
easy to handle them properly.
- You see a too strong laser light only twice in your life !!! :(
- You MUST adjust the laser power so that max. 1mW of optical power can
get through the open iris of a human eye (that's 1cm diameter). Then it
is safe. Better is less power. I feel 300uW as too strong too so adjust
it less.


Thats why I tell you FIRST SAFETY INSTRUCTIONS:
1. Don't stare into the beam! NEVER!
2. At first experiments don't use Infra-Red (IR) laser. That means, dont
use CD-RW pickup.
3. InfraRed is much more dangerous, because you can not see it. So
please use a red LD.

I think first also read entirely the Sam's Laser FAQ:
http://www.kellerstudio.de/repairfaq/sam/laserfaq.htm

After that:

Advices:
0. Get some bad DVD-Burners, or at least readers (I had the luck to get
2 pieces of LG GSA 4081 and 2 pieces of LG GSA 4082.) Ebay is your
friend. All of the red lasers were going, and 3 of the IR-s.
1. Get an oscilloscope! Without it you are lost.
2. if possible, first dont disassemble the pick-up head, but put an
oscilloscope on the laser legs, and look, what it is doing. Of course
the sled motor has to be disconnected, or you have to be able to follow
the rapid head movement. You will get a useful information: How is it to
be driven.
3. more interesting is the Write operation of the head. I weren't able
to test it, because I don't have a logic analizer to see the driving
signals together.
3. Most red DVD burner LD-s have no Monitor diode, so it is easy to
decide from the measurement which is the positive and negative terminal.
But the missing monitor diode means, you have to find out, where it is
in the PickUpHead.
4. Ok, I have the oportunity to use a calibrated optical power meter,
but others don't. I don't know if there is any other means of measuring
it. So at experimenting, dont drive the laser at its maximums. It is
enough to slightly drive it over its threshold current. Threshold means,
that if you give it more current, it gets brighter, but at a given point
it begins to radiate _really_ strong. After that the light power is
proportional to the current.
5. Dont disassemble the Pick up head. It is more secure for the LD to be
 fitted into it, than floating around in space durig tests:)
6. if you get out the LD, then build yourself an APC and test its
stableness via the osci. A swinging APC is the LD-s dead. (and disturbs
the signal).
7. Best is, you put a 1Ohm resistor in series to the LD, and monitor on
that resistor the current of the LD.
8. read lots of LD datasheets. You will get familiar with the important
values and average current caracteristics.
9. if you use only a constant current drive, and no APC, be careful. An
LD increases its radiating power at decreasing temperature, and
vice-versa. So if you adjust a LD in room temperature slightly over
threshold, the same will exceed its maximum power if you cool it down.
So for tests a constant current source is OK, but not for stable
operation in outside environment.

Ok, thats all for now,
Martin

S trafem padlo 65m.
Nize uvedene featurky jsou sice pekne ale v realu temer nanic. Se o to snazil
jakysi Crusader a vysledek byl ze cena vyletela prudce nahoru pri takrka
nezmenene uzitne hodnote proti Ronje.

Je tam nejaka varianta ATmega. Akorat ted nevim jaka, v editoru DPS mam jenom

a co takhle ten tvistr i s destickou dat do tx tubusu a udelat kombinaci 
Twister +Tx?  Z rx roury by vedlo jedno utpco do tx roury a z tx roury 
utpcko k PC. tam by byla krabicka zajistujici poe. a obyc utp do PC. 
nebudou se muset vymyslet standardy ktery drat bude kery, bo do PC to je 
jasne, a Rx by snad nikdo do PC nestrkal. usetri se penize za dvoji 
kabelaz k rouram, prace vyrabet krabici a konektory na twistrovi ( ta 
poe krabicka by byla velice jednoducha). nevyhoda je, ze neni vhodna 
hotova levna pocinovana krabicka, ale zjistil sem ze cca 1m^2 
pocinovaneho plechu ve ferone stoji 72Kc coz mi pride jako dobra cena. 
no ale pokud ma byt tvistr2 mensi, tak by se mohl rozsirit o tohle a 
bylo by to idealni, nemyslite?

pak by me zajimalo jake obvody pouzivate k pripojeni utpcka? resite to 
jak na twistrovi? nebo nejak jinak? je nekde nejake vhodne schema jak to 
zapojit? diky

Protoze jsou zlaceny, stineny a kdyz se zasroubujou, nedaj se nevedomky
uvolnit cuknutim za kabel. A nestalo se mi, ze by nemely kontakt kdyz
jsou zasroubovany.

A proc jich je tam tolik?
2koaxy kdyz uz to mermomoci musi byt by se vesli do jednoho. Na vrchni kolik
pripajet stred a na spodni radu opleteni.
Ja to stejne budu definitivne resit pres ty RJ45 aby se snadno nechaly pripojit
2*TX na dualhead.

Zde jsou nejake fragmenty http://wiki.twibright.com/index.php/RxPcbSeligr 
Nevite nekdo v cem delal osazovaky na twistera a spol Cipis? Bych podtraboval
udelat prehledne osazovaky pro 4 zakladni varianty.

Takhle jsem resil "SUGAR CUBES" - http://laser.webpark.cz/cheapo.html 
Jenze prusvih nastane v okamziku kdy chces vymenit laser<>LED a druhy prusvih je
nejak to rozumne uchladit. V demonstratoru gigabitu jsem to resil tak ze je to
na jedne desce rozdeleno na moduly, ktere se nechaji odlomit a pripojit zvlast
pres kabely. Neni pak problem pouzit treba jiny prijimac.

V nize avizovane desticce je trafo napojeno primo na twister.

rj45 jsou taky zlaceny a nacvakle to je za 60vterin. se zameckem a kdyz
clovek neni lempl tak spolehlive. krom toho jeden konektor na pcb stoji
9korun a na kabel asi korunu. za 15korun je konektor stinenej a s ledkama
ktere by se dali pouzit na tx a rx indikaci. proc to delat jednoduche... ale

Good evening Guys!

Finally i got my digital camera...

Here is an eye-pattern picture of a MLT3 signal (100Mbit/s).
Enjoy!
Parameters: 15m utp cable, with 100 Ohm terminating resistor.
Speedtouch router, 100Mbit/s full duplex,
0,2 us/div and 0,5 V/div

I think it is possible to use uncomplicated interfacing, to transmit this.

Bye,
Martin

Nacvaknout se to mozna spolehlive da, ale v tom konektoru samotnym to
nekdy kontakt nema. V praci experimentujeme s ethernetovymi zarizenimi a
casto musime ke switchi a vaklat tam konektorem, aby si to sedlo.
Presto, ze jsou oba kontakty zlacene. Je to protoze to ma nedostatecne
mechanicke tolerance, plastik se vybeha a oddali se to obcas natolik, ze
se ty dratky uvnitr proste nedotykaji. A to i presto ze switch i snura
jsou pomerne nove.

Protoze kdyz clovek pouzije poradny venkovni koaxial s dvojtou izolaci
(takovy ten zeleny), tak se mu 2 do jednoho canonu nevejdou. Proto jsou
tam na signal 2.

Treti canon je na napajeni, protoze se mi stalo, ze ty koaxialni
napajeci konektory nemely kontakt a muselo se s tim vaklat. Predpokladam
ze kdyz to uzivatel nekde nainstaluje a vzpomene si to ze to prestane
mit kontakt, ze bude celej blazenej sednou do auta a nekam ject aby si
zavaklal a zase cekal, kdy to prestane fungovat.

Tomu konektoru pritom nic nebylo - pruzina byla napruzena spravne,
nebylo to zoxidovane, soucastky byly nove a prumer trubicky a tycinky
sedel. Proste to neni zlato na zlato ani plasticka deformace, takze to
nema narok fungovat.

Podle me canon neni problem - dirky se vyvrtaj a lichobeznikova dira se
vystrihne nuzkama (bude na kraji a nebude uzavrena). Vzhledem k tomu ze
to bude podle sablony tak to ma uzivatel hotovy hned. Ale jeste jsem to
prakticky nezkousel.

no nevim, na siti mame asi 100switchu, 15 routeru, 8ronj (vse s poe a rj45
konektorama pres spojky jak nahore u roury tak dole u routeru) nepocitace
ap, wrapu a jineho neradstva a nikde nicim vaklat nemusime aby nam to
fungovalo. udelej to apspon volitelne na rj45, usetris lidem praci aby si
delali vlastni desku nebo penize za redukce canon-rj45 coz se prodava.
jedine co me na ronje kdy zlobilo byli prave koaxy ktere sem pak okamzite
nahradil utp kabelem a od te doby sem prakticky na strese nebyl skoro po 2
letech provozu nejstarsich kousku.

Ta krabice je ale velka jako krabice od bot a je dvojita. Da se z ni
udelat spousta krabicek. A letuje se to dobre protoze to je tenky plech.

No uvidime ale nedokazu si predstavit co by na tom melo byt sloziteho.

Volitelny to muze bejt - uzivatel si to muze otevrit v programu PCB,
canony smazat, dat tam footprint konektoru RJ45 a pripojit tech par
dratecku a vytisknout to do gerberu a ma to. Ja tam RJ45 z vlastni
iniciativy davat nebudu, z vyse uvedenych duvodu a taky protoze se do
toho neda rozumne pripojit koaxialni kabel, natozpak 2 vedle sebe.

hm, no jak chces no, ale kdyz uz se tady dela twistr2, nestalo by za 
uvahu udelat rovnou ronju2? ruznych zlepsovaku uz tady padla hromada, 
tak co je dat nejak dohromady a udelat byt nekompatibilni, ale 
vylepsenou ronju? sice me napada, proc delat ronju2 10Mbps, jestli by to 
nebyla zbytecna prace, jestli ta dvojka by nemela byt rovnou 100M. btw 
na cem stoji 100Mbps kdyz se pominou prijimaci a vysilaci optoprvky?

Taky je mozny ze mate CRAP-O-MATIC kleste jako ja. Na prvni pohled vypadaji
precizne ale na pohled druhy maji malinko posunute zuby. Kdyz se zamackne
konektor tak nepatrne zdeformuji plast kolem kontaktu, ze si toho clovek
nevsimne, ale kontakt nezapadne. Taxem si koupil nove, nejlevnejsi, mnohem
jednodussi kleste za 4kila a uz je to OK.

Pak to chce ale nejak osetrit aby to tam clovek nenastrkal blbe, aby se z neceho
nezajiskrilo. U stavajiciho twistra kdyz se zameni privod koaxu za UTP tak se
zakouri ze sitove karty.
A jestli muzu pridat fr, tak kdyby LED diody mohli mit vyvody na 6 nasobnem
konektoru hezky u sebe.

100Mbps stoji na tom ze je na vyrobu radove narocnejsi nez stavajici ronja.
Optoprvky nejsou zas az takovy problem, podle mych mereni se 100Mbps necha
prohnat pres kombinaci laseru z gme a BPW43. Problem je v domacich podminkach
zapajet pokrocilejsi pouzdra nez je SOxy a pak nastavit laser driver, i kdyz
moznosti tu jsou - http://www.mcu.cz/modules/news/article.php?storyid=525
Na druhe strane takovou Ronju2 uz mam skoro hotovou. Achilova pata jsou prave ty
koaxy, ktere brzdi pokusy o dalsi zlepsovani.

Mam dotaz,
pokud uz delas komplet novou ronju, nebylo by lepsi roztahnout utpcko, tx 
par do vysilace, rx par do prijimace a mezi nima natahnout jenom kratky koax 
se synchronizacnim hodinovym signal pres pll + napajeni?
Moc do toho nevidim,(tudiz mozna placam nesmysly:-) ale proc tam tahat koaxy 
kdyz ma 100baseT oddelene signaly?

Jejda a pro? nevyhodit ty koaxy nadobro?
V?dy? m??ga to m? ov??en? s TP a dokonce s lep?? citlivost?...
Pi?lat kanon je opruz, obecn? jak?koliv nekruhov? nebo ne?tvercov?
(obd?ln?kov?) d?ra.
Zm?na v ti???ku je snadn? na po??ta?i, ale jsou to naprosto zbyte?n? n?klady
na masku.
Sta?? jedna maska pro v?echny a dostane se to na rozumnou cenu, pochybuju,
?e by si ka?d? nechal d?lat podklady zrovna pro ten sv?j konektor.

Nastavit laser driver by mohlo pomoct treba tohle http://www.analog.com/en/prod/0,,1074_845_ADN2871%2C00.html
Sice se to paji zdanlive blbe ale trocha pasty a horkovzduska by to mozna taky resila.

To nejde - privod koaxu jsou svorkovnice a UTP je RJ45, to do sebe
nejde.

Co se tyce canonu, kdyz se prohodi kabely nevadi to protoze oba
konektory maji stejny pinout. Kdyz se strci napajeni do signalniho nebo
signalni do napajeni tak se nic nestane protoze jsou na signalu
kondenzatory.

Kdyz ma nekdo tenky kabel tak to naletuje do jednoho canonu a druhy
necha nepouzity.

LED zadnej konektor mit nebudou budou zaletovany primo v desce.

to bylo odbugovany a mohla se vyvijet 100Mbps a dalsi veci.

Sorry, to nebyla reakce na tvuj debug, to bylo smerovano na Petra Seligra a
jeho 100Mbps verzi.

so To Petr Seligr:
Mam dotaz,
pokud uz delas komplet novou ronju, nebylo by lepsi roztahnout utpcko, tx
par do vysilace, rx par do prijimace a mezi nima natahnout jenom kratky koax
se synchronizacnim hodinovym signal pres pll + napajeni?
Moc do toho nevidim,(tudiz mozna placam nesmysly:-) ale proc tam tahat koaxy
kdyz ma 100baseT oddelene signaly?
btw: myslel jsem tim bez twisteru=>kazda roura vlastni elektroniku

wacx

Ja nedelam komplet novou ronju, ja pouze opravuju jednu chybku ktera si
vyzaduje predesignovat cely twister. Ani na twisteru nedelam dalsi zmeny
ktere se chystam do budoucna udelat, protoze povazuju za dulezitejsi aby
to bylo odbugovany a mohla se vyvijet 100Mbps a dalsi veci.

Byla ta zila tvrdy drat nebo lanko? Z jakeho kovu byla a z jakeho bylo
pokoveni? Jak bylo overeno ze se utrhlo pokoveni a ze to nebyl spatne
priletovany spoj, kde se utrhla pajka od stredni zily koaxu?

Jestli je to fakt jak rikas tak bych mel do pozadavku na koaxial napsat
ze takovej, u kteryho se neloupe pokoveni ze stredniho vodice.

Message-ID: <4429A3B4.4050802@centrum.cz>

mnaga psal ze zkousel 2 lupy s luxeonem a ze byl problem se zamlzovanim. 
bavim se tady s lampicou a 2ma lupama a cumim ze to je fakt dost 
zajimave kdyz se daji ty 2 lupy na sebe ... myslim ze by stalo za to to 
nejak vyresit to zamlzovani ... nevim co to bude delat s paprskama na 
kilometr, ale zatim mi to zkratilo ohnisko na polovinu coz je docela 
dost. To mnaga: co vsecko si s tim pozjistoval? myslim luxeon + 2lupy... 
jake to melo chyby krome mlzeni? to by se ostatne dalo vyresit tim, ze 
se daji do vetsi trubky a ta vnitrni nebude s tou vnejsi nijak utesnena, 
ale naopak, bude tam volne misto. a vytapet se bude klasicky jenom ta 
vnejsi ...

Kabel se pouziva venku a tak musi byt urceny na povetrnost. Normalni STP
ma tenky plastovy obal a neni urcene na povetrnost. Koaxial na
povetrnost se snadno sezene, protoze se s nim tahaji anteny od televize.

Dal je tam crosstalk mezi parama a nevyrovnana frekvencni
charakteristika paru, coz muze teoreticky zpusobit jitter a snizeni
dosahu. Jestli to jitter zpusobi nebo ne jsem nikdy netestoval.

Pak se to spatne konektoruje - krimpovanym konektorum neverim. Konektory
jsem osobne krimpoval a obcas byl nejaky dratek vadny. Kdyz to nejsem
schopen zvladnout ja, tak mene zkuseny uzivatel tezko. Zrejme je potreba
nejake vysoce kvalitni kleste volene podle toho jestli to je lanko nebo
tvrdy drat, coz se hur shani nez canony a je to celkem velka investice
(nekolik set?)

Message-ID: <20060329085856.GA5553@kestrel.barix.local>

Jo jeste dalsi problem je ze STP je cca. 6-7mm tlusty takze se tezko
dava do mist kde se musi kabel tahnout skvirou nebo prudce zalomit.

Naopak sehnat 3mm tlusty koaxial neni problem (dela to Belden) a nebo se
misto toho da pouzit i stinena audio dvoulinka ktera je taky jen 3mm
siroka.

Vzhledem k tomu ze lidi maj casto problemy s tim aby jim to rodice
povolili, ze neni misto na kabely (napr. doma jsme kabely museli dat do
skviry mezi podlahou a stenou), tak si myslim ze je lepsi kdyz je to na
koaxialech nez na STP.

Chapu duvody pro i proti TP kabelu. Elektricke vlastnosti ma zrejme koax 
vyhodnejsi - o kolik necham na jinych.

K mechanickym vlastnostem: povetrnostni podminky. Mame UTP natazeno mezi 
nekolika domy, nikde nevisi ve vzduchu a jde bud po zdi nebo je zakopan 
v zemi (ne hluboko). Mame to uz 2 roky a vubec neni videt nejaky 
vyznamny destruktivni vliv pocasi na plastovy obal.
Ohebnost kabelu je dana pouzitim dratu nebo lanka, mirny rozdil v cene 
kabelu. Nacvaknuti konektoru je jednoduche a rozhodne se neda rici, ze 
doma delany konektor je horsi nez lisovany ve fabrice. Je treba 
rozlisovat konektor na lanko a drat ! Kleste pouzivam nejlevnejsi za 400.

Jarni prace na zahradach: kazde jaro nam kabel nekdo presekl kosou nebo 
  rycem v zahradce :-) Sletovali jsme kabely k sobe zaizolovali a vesele 
to bezi dal. Cekam, ze letos to opet nekdo presekne :-(

Indukce na kabelu ze vzduchu: jednou nam shorel switch, kdyz uhodil 
blesk do domu asi 300m od spoje. Byla to pecka, ze v cele vesnici, 
shorelo par zarizeni, nejen ethernetovych.

Nepisu, ze chci pouzivat TP. Na stavbu dalsi Ronji se nedostanu kvuli 
casu, jen dodavam informace pro lepsi rozhodnuti.

Honza H.

PS: www.zernovice.net
Nase Ronja asi neni v seznamu spoju.
Od navodu se lisi, ze neni kovova krabicka twisteru.
V provozu je uz dva roky, ale prvni rok nebezela jako paterni spoj 
nepretrzite, ale jen jako pripojeni jednoho stroje (jedna strana se 
zapinala s pocitacem).
Delka koaxu od twisteru do hlavic je na jedne strane 25m.
Mame upravene Edimax switche do FD - zajima nekoho jak dopadlo mereni 
rychlosti? Nic moc, namaha za to asi nestoji.
Ruseni TV je znatelne a zvetsuje se s mnozstvim prenasenych dat.
Uz jste nekdo musel menit TX LED kvuli zivotnosti?

pouzivame kleste za 2 nebo 3 stovky z alza a neni problem.
venkovni utp se da sehnat taky. a pak postaci i pro vnitrni pouziti, mame
nekolik let prevesy mezi barakama tim obyc a v pohode. to ti driv shnije ta
kovova roura od topeni nez ten kabel. me ne, ja ji mam plastovou ?)

typ toho koaxu uz nevim. ale uz sme o tom problemu tu psal a nebavime to
psat znova. rikal si ze to napises do navodu uz tenkrat.

Odolnost kabelu je velmi podobna. Zkusenost mam ze vnitrni RG58 i UTP vydrzi min
5 let. A venkovni UTPcko je levnejsi.

Pro 10Mbps jsou nejake nevyrovnanosti kmit. charakteristiky uplne sumak.
Crosstalk je taky pase nebot pouze jeden par vede signal. Tj. TX ma svuj kabel a
RX ma svuj kabel.

Kleste nejsou potreba nejake extra staci za 400Kc. Ale fatalni je rozlisit
konektor na lanko a drat. Na lanko ma dva hroty, na drat takove tri pasky vedle
sebe.

Jsem si s tim svitil na asi 200m a vysledek celkem OK. Od te doby to lezi v
koute. Otazka je co provedou opticke vady takove kombinace s paprskem nekde za 1
kilometrem. Az sleze snih tak se na to jeste podivam.

Kabely s pocinovanym strednim vodicem by se nemely pajet a obecne nejsou vhodne
pro vf pac povrchova vrstvicka ma spatnou vodivost. Pokud jo tak pouze ne moc
dlouho skladovane. V tenke vrstvicce cinu vznika intermetalika (Sn6Cu???) ktera
je nepajitelna. To je taky duvod proc galvanicky cinovane plosnaky nejdou po
nekolika mesicich pajet a kdyz jo tak s mnozstvim studenych spoju. Proto se
pouziva HAL.

Sorry, mej jsem jednodenni koma po degustaci moravskych vin.

Jde o to ze neni uplne nova. Porad se pouziva twister a lze zachovat stavajici
moduly po malych upravach. Ale lze velice snadno pridat nove veci jako laserovy
TX a citlivejsi prijimac a rychlejc se to montuje. Hlavne se planuje na upgrade
stavajicich spoju.
Za domaci ukol nakreslim skicu jak to vypada.

spis ze srandy jsem si spocital kolik 130mm cocek by muselo byt aby se 
do ni vlezlo svetlo z luxeonu s vyzarovacim uhle 140 stupnu. vysly 
myslim 4 :) tezko rict kolik vad ma vietnam cocka, asi hodne moc, ale ze 
srandy to mozna vyzkousim :)

ten drat byl pomedenej nebo tak neco, cin to nebyl, nevsiml jsme si toho a
pajel to. dopadlo to tak ze sem tam daval cokolady. ale to je uz davno,
nebabrat se v tom, jen napsat do navodu ze drat s zilou pokovenou nepajet a
nejlip asi ani nepouzivat.

Kabely s pocinovanym strednim vodicem by se nemely pajet a obecne nejsou
vhodne
pro vf pac povrchova vrstvicka ma spatnou vodivost. Pokud jo tak pouze ne
moc
dlouho skladovane. V tenke vrstvicce cinu vznika intermetalika (Sn6Cu???)
ktera
je nepajitelna. To je taky duvod proc galvanicky cinovane plosnaky nejdou po
nekolika mesicich pajet a kdyz jo tak s mnozstvim studenych spoju. Proto se
pouziva HAL.

Jo v pohode, to me nenapadlo. Pak samozrejme do kanonu muzu napajet UTP a je to.
Jeste by to chtelo oddelit signalovou a napajeci zem na RX. Tj. naklonovat
soucastky C109 a R70 pro positivni vstup prevodniku U62 a vytahnout je na
cannon. Kdyz se pripoji koax tak se toto pripoji na stineni a tim se vyrusi
ruseni vzhnikle spatnym blokovanim a v zemeplose (coz je pruser stavajiciho
twisteru). A kdyz se pripoji symetricke UTP, tak no problem. Jen bude potreba
presunout vazebni kondenzatory kvuli tem 12V na stineni.

OK, chysta se jeste nejaka revize stavajiciho twisteru?

No jen je trochu problem tyhle obvody sehnat v kusovce. Uz i Analogove se
zacinaji osivat se zasilanim samplu do CR. Lada do crusaderu to objednava po
min. desitkach ks, coz je pak suma o dost vyssi nez kdyz objednate 120 diod do
TX. Navic vime jak se sveho casu objednalo hafo ML6652 a valna cast se vali
lidem v suplikach...
Druha vec je nastavit proud laserdiodou bez merice optickeho vykonu aby to nejak
kloudne chodilo a vydrzelo. Monitorovaci fotodiody maji u levnejsich laser diod
moc velky rozptyl.

Si vzpomen na sve ozivovani nejaky patek na zpatek :) A stavi to jeste vetsi
vohnouti.
Ono to chodi vice lidem, stacilo jen oprasknout ref. zapojeni nejakeho
mediakonvertoru na 100Mbps.

no tak ... je to trosku nazelenale pri vetsim mnozstvi :P ... ale 24 
jich tady teda nemam :)

moje ozivovani je nastesti naky ten patek zpatky ... to sem tomu hold 
tolik nerozumel... jako pokud to lama neozivi tak se proste napise lamy 
nedelejte to, pro lamy je tu ronja 10Mbps, ktera vam s velkou 
pravdepodobnosti pojede.

btw kolik lidi to drzelo ten sloupek tech 24 lup? :P

Mas na mysli ML6652 nebo nejakej jinej?
Podle me vysilac by sel udelat pres Realtek 8305 (switch chipset, kterej 
umi prehodit vystup do PECL, napr. edimax 5 port za 450,- prave jsem mu 
pridal eepromu a nakonfiguroval ho jako VLAN switch) a prave ten 
ADN2871. Pro me je problem si spis predstavit kvalitni prijimac a prevod 
na PECL

Can anyone write an abstract in english or german from the last 30 
emails of the list?
I think Babelfish is not ready for Czech or Slovak language support :(

Thanks :)

It's a kind of flame war whether to use UTP (some people think that UTP 
can be drop-in replacement for coaxials) instead of coaxials and whether 
to use Canon connectors (Clock thinks UTP and its connectors are 
unreliable) in redesigned twister.
Then we are taking hard left to some technical experience with laser 
driving and finally we are getting to a thought, whether wouldn't be 
better to leave ronja as is and develop new 100Mbps version with laser 
driving on SMD PCBs. Clock says, that finally it is true, but that he 
must leave 10Mbps Ronja in bugfree/stable state before developing new 
version :)

Hope didn't miss anything,

K

To by se pak ale taky mohlo rict ze lakovany medeny drat ma spatnou
vodivost protoze povrchova vrstvicka laku je silne nevodiva.

Podle me je tenhle argument zcestny a plati tam slozitejsi vztah.

Vcera se mi podarilo odloupnout vrstvu cinu na pocinovanem plechu kdyz
jsem odletovaval dva sletovane plechy a pri rozehrivani jsem aplikoval
moc sily.

Pisu si do TODO listu zakazat vsechny koaxialni kabely ktery maj stred
tvrdy pokoveny vodic protoze co ty pokoveni predvadej to fakt neni mozny
:)

Ale dirky na epromku tam byly taky.

Presne to myslim, neni tam zadny mlt3, zadny scramblovani, primo signal pro optiku v PECL urovnich.
Imho je to presne to co chce ten laser driver na fousech datap a datan nebo jak se jmenujou...

Ten edimax je malickej, takze se vejde v pohode do roury cili moznost koaxu az do roury.
Akorat ze by se mysela vymeslet propojka RX x TX hlava. Ale precpokladam, ze to nebude snad az takovej problem.

Mozna se da nekde sehnat ten chipset jako takovej. Je to RTL 8305SC. Ale pokud switch stoji 450Kc...

Hehe. Thats cool. Clock is right.

Some experiences:

It is almost impossible to get laser driver IC-s. I wanted to get some 
samples from Maxim and Analog Devices, but they have shipping dates of 
august or later.

So a stable but easy to handle laser driver made of discrete components 
would be a real advantage.

Converting the MLT-3 to a binary signal is easy (2 comparators and some 
logic), but regenerating the mlt3 in the rx part needs a more complex 
logic, and maybe a PLL.

I am still developing the TX part...

Bye,
Martin

Building a 100MBps laser driver isn't too hard, as long as you (a) 
accept that Feedback Is Futile (at least at nanosecond levels) and 
(b) you're not switching much more than, say, an Ampere (or two).

Why is everyone so intent on using lasers ? The LEDs I've tried can 
be driven fast enough without much problems, as long as you use a 
switched current source and not a switched voltage source. Also, the 
LEDs I've tried handle abuse much better than laser diodes do.

I've been working on my link too, the last few days. The plan is to 
buffer the incoming data and possibly do rate conversion, to allow 
the user to trade-off between link speed and distance.

As far as I can see, the problems are (from hard to easy):

- Receiver PLL/clock recovery
- Receiver frontend
- Using only easy-to-get, easy-to-solder components
- Transmitter frontend
- Word sync / error correcting code
- Wire interface (ie to/from 100Base-TX)
- General system control

I'll see if I can generate a demo schemo for the LED/laser driver. In 
the meantime, if anyone has suggestions on how to generate a 66MHz 
signal from a 132MHz signal where the rising/falling edges of the 
66MHz signal coincide with the rising edges of the 132MHz signal 
*over a full outdoors temperature range*, I'd much appreciate it.

My options so far:
- use a PLL to align the edges (complex, may introduce phase noise)
- build an analog DLL (hard to keep working over the full temp range)
- use an FPGA with integrated DLL (hard to get, hard to solder, expensive)
- use a specialized DLL chip (the project dies when the chip goes out 
of production).

Thanks,

JDB.

If I uderstand it well, if you use the RTL chpiset than you do not have to worry about data recovery and PLL. I do not have time to read it now but I think I saw it in the RTL8305SC datasheet....

bohuzel, v kazdym switchi edimax 5port co ted koupis najdes pouze RTL8305SC,
takze bych timto chtel poprosit uzivatele kteri maji doma switche nejake jine
znacky nez edimax aby koukli co je v nem za cip, chce to najit ten SB v necem co
se prodava.. jinak ten byl vzdycky ve starsim vydani 5-ti portoviho edimaxe, ale
ty uz se neprodavaji

We're talking about two completely different things.

Current Ronja (and some of the plans for 100MBit Ronja) mostly work 
by connecting the Ethernet wire to a LED on one end, and a photodiode 
on the other end. It's a gross oversimplification, I know, but in 
essence you'd be sending the same waveforms over the air as would 
exist on an Ethernet cable (or fiber, for 100Base-TX). This could use 
RTL (or other) Ethernet chipsets.

What I propose is to 'demodulate' Fast Ethernet into bits, buffer 
these bits, apply error correction algorithms, change the Ethernet 
preamble to something more suited for an optical link and, 
optionally, *change the transmission rate* so that a longer link 
might work more reliably on, say, 50MBit.

Ronja works similar to a repeater in the original Ethernet 
specification. What I plan to do is similar to what happens with 
point-to-point microwave links. It's more complex and likely a bit 
more expensive, but much more reliable.

Ethernet wasn't designed to be used on a noisy medium: one bit error 
in 12000 is enough to ruin an entire packet. At a previous job we 
worked on an experimental 60GHz data link. Originally we used plain 
Ethernet, very much like Ronja. Later we added error correction like 
I propose to do, which made the link much more robust.

Subject: [Ronja] Ronja - 100Mbps
Message-ID: <ops68iveatn6qjls@daman>

Hi,
 from my point of view is optimal way to develop reasonable 100Mbps FSO  
using more discrete components and less complex chips such as FO  
transceivers/convertors, laser drivers, transimpednace amplifiers etc.,  
which are difficult to get. Yes, it's easy to develop, but difficult to  
build it and developing is did only once, but building not ;) I think,  
that for build convertor between ethernet(MLT-3) and optical  
signaling(NRZI) is suitable some smaller FPGA(Xilinx Spartan II family  
might be good - is easy to get and relatively cheap). In this could be  
also easy implemented switching between 10/100Mbps, management or  
eventually more features.
Laser TX can be easy build from discrete components as write Martin. In my  
opinion the hardest part will be rx - it must have low noise and high  
bandwidth. Somebody(I think it was Petr Seliger) wrote something about  
transimp. amp. built from discrete components.
Another very important part of device is mechanics and optics, but i  
haven't thought about it lot..

FPGAs are often very hard to get, even during their lifecycle.It 
would be nice to still be able to build Ronja100 in, say, 5 years; a 
Spartan II may be very hard to get hold of in 2011.

translation from Czech is plastic gooseneck but google shows it's
probably not the right term.

No we arte not. I said that I'm considering the RTL8305 to switch from 100TX mode to 100FX mode.
So there is no MLT no scrambling but signal ready for optical communication.
May be I'm missing something.. May be you understood my previous message in wrong way.

Should'nt it be possible to hack a DVD-Writer into a sender/receiver ?

Everything should be there: optics, laser driver, amplifier ...

Maybee some DVD-writers use chips with available datasheets (like maxim

Would this enable to have just one tube to do sending/receiving ?

Message-ID: <20060330161029.GA21800@kestrel.barix.local>

We had dropout of Ronja Trac and Ronja SVN because wservices.ch were
upgrading the server by making a different one and copying the data.  I
didn't get notified and they didn't know a special software (SVN, Trac)
should be installed on the new server as well. So it took some time
until it was realized, I asked them and they installed the software.

There was some problem with Trac Debian package (a bug of Debian) and
also the SQLite database was unreadable because a version change, but
the wservices.ch guy found this and fixed it immediately (definitely
faster than I would figure it out).

Now Trac seems to work only the logo at the beginning is replaced by
a nonsensical HTML code. The tickets seem to be there again so I hope
it will be again usable by general public.

Trac seems to be a kind of software that cannot read it's own data files
after a version upgrade (which will inevitably result sooner or later
from ordinary system maintenance).

Would it be possible to connect ronja transmitter / receiver to a 
100mbit switch or pc-card with optical output ?
The netgear FS726 and FS750 switches may be extended with the AF711F 
module, witch adds the optical parts.
Analysing the AF711F it should be possible to connect home build 
trancsmitter/receiver.
FS726 is sold for around 140EUR. 24 transseivers could be connected to 
this.

Maybee there are also cheaper options.

The fact is, that it is not called gooseneck even in czech - it is 
called "chranicka" or "elektroinstalacni trubka/kanal". I took a look on 
website of Kopos Kolin, which is making them and their catalogue says it 
is called wiring conduit. If it is "goose" then it is flexible. So the 
whole is: Flexible wiring conduit/s.

But HDL code can be synthetized into another available device.

I'm really don't believe, this part can be replaced by some discrete  
components and some primitive ICs such as 74xxx logics. Just look on ronja  
twister. There are a lot of logics ICs and it's only 10Mbps interface  
without autonegotiation function.

No jasne to chapu. Ptal jsem se jestli tusis od jake cenove hranice uz 
ma ten laser prijatelny parametry, ze by sel pouzit ten svab bez dalsich

Thats why i began to play with it.

What I could see is no conventional IC. They are all ASIC-s.
It would be nice, because most driver IC-s have current channels. This
means, you can switch between more power levels during modulation...

For example in LG burners the IC is on the PUH. Sadly noone knows, how
to connect the PUH :(
A fast logic analyser is needed for this.

> Would this enable to have just one tube to do sending/receiving ?

I dont know how professionals do it, but they have done it.

Maybe a polarity change is good for this, but dont expect too much from
it. The problem is, that you want full duplex, and the sent data is
disturbing the receiption. I heard, polarity change means an attenuation
of 20 dB only. (is that correct?) So if the received signal is less,
then you hear your own mess.

I did understand that part, but I see I made a typo which may have 
confused matters:

                                ^^^^^^^^^^^^^^^^^^^^^^^^
Here I meant to say "(or fiber, for 100Base-FX)"

Yes, by going 100FX you lose the MLT3. You still don't get any error 
correction coding or variable transmission rate. This is what I'm 
trying to achieve, so I can't use the PLL in the RTL8305SC.

I know that 100FX is 'ethernet over light', which is what we're 
trying to achieve. But air is a very different medium from either 
multimode or single mode glass fiber, and I'm pretty sure you get 
better results with a system tuned for air. 100FX over air may well 
work, but likely with less range.

Yes, but then you need to re-do (most of) the design anyway. That's 
not much different from needing a different special-purpose Ethernet 
chip.

Absolutely. All I'm saying is that FPGAs are probably not the best 
choice. Many CPLD families have longer life cycles, need fewer power 
supplies and come in packages which are easier to solder.

Now that I think about it, I suppose that the digital parts of the 
design I have in mind could be implemented in a dozen or so 74LVCxxx 
chips + some memory. That's including the error correction/detection 
algorithms. A CPLD is just much nicer to have while prototyping ;-)

Thanks. I wrote it into the guide together with banning plated hard

Jedina wifikundace je v tom nastavit jednim potakem opticky vykon. Jde jen o to
ze pomer fotoproud monitorovaci diody vs. opticky vykon z laseru se lisi o
konstantu. Fotoproud ma velikost radove 10-100uA na mW vykonu. No a dejme tomu u
10mW diody kdyz prestavis o par mW tak snizis jeji zivot o tisice hodin.
A vtip je v tom ze bez meraku optickeho vykonu muzes jen hadat.
"Vochcat" se to da pouzitim VCSELu ktery neni tak haklovy jenze si to zase shanej.
Nebo druha moznost je pokud mas promerenou Pout/I charakteristiku diody a vys
jak ten laser funguje, tak se pomoci uP da udelat autokalibrace.
