Did the red LED flash during the packetloss - ping test which has 100%
packetloss?

So the wires are OK but the electronics is dead.

Try to melt down all joints again using a soldering iron. Send me a
photo so I see how neatly it's soldered together :)

Is the 26LS32A heating obviously more than the one in the good Twister?
Are both chips bought together?

The NE592 is separated from P106 by a capacitor so it shouldn't be able
to change voltage there.

Check the topology of the circuit around the transistors. Maybe some
wire is going somewhere else, or some part is missing, or some part was
inserted with mistakenly wrong value.

Then if it doesn't help try remelting all joints in this part of
circuit. Maybe some of them is a cold joint. Send me a picture of the
circuit so I see how neatly it's soldered.

This can be caused by auto negotiation. Ronja does not supprt it and 
both sides have to be connected to 10Mbps FD fixed. If those switches do 
not have port speed switching (not managed), you have to obtain managed 
switch which ports can be set so.

Does the PL appear when connected to PC NICs with 10Mbps FD set?

But in that case the link should just run half-duplex.

Packetloss is caused when one side is set to half duplex and the other
to full duplex.

I thought, that autonego feature can fail in such situation and 
therefore can cause packetloss with changing port parameters - I saw 
such behaviour on one NIC and a switch - but maybe the switch or card 
was broken...

it looks like my packetloss was caused by faulty switch. i changed it
for 100Mbit Linksys WRT54G and it works fine, either in FD or HD.
so now i have 10Mbit on one side, 100Mbit on the other.

Hi,

I am thinking about building the Spider module for future replacement of
the Twisters I have and was wondering if the DS26LS31/32 can be used in
place of the MC3486/87 as the place I'm ordering from has discontinued
MC/DS3486/7 .

Thanks in advance,

Subject: [Ronja] EPS support
Message-ID: <20060709204018.GA11757@kestrel.twibright.com>

Does anyone need EPS outputs from Ronja?

I am going to drop them because:
1) Inkscape doesn't compile on OpenBSD 3.9 which I am using. When I made it
compile by fixing about 30 places where it wiped out, it hangs and when run in
gdb, segfaults.  Sodipodi from which Inkscape is forked works fine so I falled
back to Sodipodi. Inkscape could generate EPS, Sodipodi can't.
2) ps2eps I used in Ronja was buggy - corrupted bitmaps if their ASCII
representation contained certain regexp pattern that it searched for.
Because the whole design was based on wrong assumption, 
it couldn't be easily
fixed.
3) ps2epsi, an official script from Ghostscript, is broken. It bases the
bounding box on 1-bit b/w representation of the page. I have a red on white
postscript and the red is closer to white than black, so it prints
an error "Blank page!" and produces an invalid, partial output. It would have
to be rewritten to use gs -sDEVICE=bbox but that would take too much time.

Subject: [Ronja] ps2epsi peoduces invalid output
Message-ID: <20060709205221.GA17858@kestrel.twibright.com>

ps2epsi from AFPL Ghostscript 8.14 (from OpenBSD 3.9) produces invalid output
on the attached tbl3.ps. It says "blank page!" and produces partial, invalid
EPS output.

If the colour is changed from red to black, it works.

>From the source I have a feeling that it's converting to image into
1-bit BW and using that to calculate bounding-box. The red turns into
white and the page is then considered empty.

I suggest to use 48-bit sRGB colour space to test for white or
gs -sDEVICE=bbox to calculate the bbox (that works even on this postscript).

Or you could add a variant of the bit device where all primitives are drawn
with black, just to support this script.

Aren't the LEDs connected in the wrong polarity?
The PCB looks good.

Did you do anything that could kill the 26LS32A? Like don't you have 110V
on the case of your PC or something like that?

Remove the 26LS32A, put there a socket and put a new one into the socket.
Then try if it works.

Hello Moe:

I believe the best source for this kind of stuff is the Yahoo Group on
LTSpice which I am also a member I know there are files there in the group
that modelled LEDs and drivers - I did some of it but I was interested on
Stochastic Resonance in optical detection. Google LTSpice or SwitcherCAD.

Regards,

Berns B.

Hi!
    
    I test my twister in a laboratory with an oscilloscope and one square signal at the input like the ethernet protocol one. The test was ok but when i try to do the pakectloss test with the ping variant or with bertest in linux, the link is not active and the twister do nothing (led red off, green off, 100% packet loss).

    I need help

Can you show a picture of boath sides of the board?
Didn't you use AM26LS32 instead of AM26LS32A?

I'm lazy to look there but I guess it's the link integrity impulse.

Can you show a picture of boath sides of the board?
Didn't you use AM26LS32 instead of AM26LS32A?

That's correct. But I need to see a picture of the washed board, the revision
number doesn't help. I can tell from that if the problem is likely to be in
soldering or not.

Ronja doesn't have to be programmed. You only need to set up software
for testing which is described on the webpage. You also need to configure
network almost like on normal wired ethernet.

I don't know what you mean with servers. The connected device needs to
full duplex on network card or switch otherwise it will run half
duplex.

Drops out in strong fog, takes long to build.

There was no ideal at the beginning. Just experiments for fun.

The development methods were focused on widely available parts and easy
manufacturability at home.

http://ronja.twibright.com, then read a bit in the About,
also Benefits, and then go into Models and select
a model you like and there are instructions how to
build, test, install and use.

So here is a picture of the defective circuit :
http://www.complex.ch/modprobe/wp-content/uploads/2006/07/DSCN0809.JPG

And we had look at the two receiver's signal with oscilloscope, and 
there is an obvious difference:
http://www.complex.ch/modprobe/wp-content/uploads/2006/07/30062006(002).jpg

 For me this seem to be a bad cap value ...  But I didn'had the time to 
check everythings, I will try to do so this weekend and to re-solder all 
joint.

This looks like one half of the circuit (one transistor) works improperly.
Definitely check the part of the circuit with bad transistors.
Also an often mistake is to forget the capacitor that goes from base of
one transistor to the ground.

It can happen that a capacitor cracks when the leads are bend too carelessly.
If you have any suspicious capacitors in the circuit, definitely change it
for a new one.

ronjashop.com is selling the PCB for 150CZK.

The costs are written here:

Unless I misunderstood them, they are not right:

generate 10Mhz fur Ethernet clock discovery is actually a
RX packet discriminator.

integrity clock for what are actually counter cascades of link integrity
impulse generator.

modulation is a multiplexer that multiplexes 1Mhz and the packets.

carrier frequency for modulation is actually TX packet discriminator.

Look at http://ronja.twibright.com/schematics/ and search for twister2.
It's virtually the same schematic, with labels what is what. But I think
the reference designators of chips (U60 etc.) are not the same.

> for what ist the integrity  clock good for ??

That's an impulse that tells that the link is alive (used in wired ethernet).
It must be there otherwise the network card refuses to transmit.

Do switchu a CB radii (aby drzela pamet)?si davam Schottkyho 1A diodu za stabilak, aby se nevybil AKU.
A mezi stabilak a chipset AKU slozenej z 7ks NiMH AA a za nej stabilak 5V nasledovany 3.3V.
Je to podobne zapojene jako:? http://ok1mjo.zajsoft.net/all/ostatni/schemata/power_backup.gif
Proste takova mala UPS. Kdyz pouziji 2500mA AA na switchi, tak to udrzi i 4h.

The cost stated on Ronjashop is for a single blank PCB, without parts.

You can't neglect anything. But you can replace some parts with equivalents,
as listed at the bottom of the partlists.

You don't need any firmware for Ronja, the only software necessary is
networking support of your operating system.

Here's hoping that Sumaiya is reading the list. If you are not, join it.
It will help you tremendously.

To get most of the components : www.rsindia.com

You can get the IR detector and the dual gate MOSFET from RS. Most of
the Twister and TX components are available in electronics parts shops
in most major cities - although Lamington Road in Mumbai is the best
place to go shopping. One piece of advice if you go to electronics
stores - DO NOT accept parts which they tell you are equivalents - ONLY
get parts that are listed by Clock - this will save you considerable
headache. An example is that most shops will try to sell you LS versions
of the logic ICs if you ask for HC. You have to get the TX led from one
of the people who are listed in the wiki. boza2 at volny.cz is one of them.
LUMILEDS India sells these LEDs in packs of 480 for around Rs. 10,000 -
not a choice.

Download the gerber files from the ronja site and you can make the
boards from this service : pcprocess at airtelbroadband.in

Hopefully you have some electronics experience. Good luck and ask away
on the list if you have problems.

hi again.

i tried to set up my own circuit around the spider cpld (i know this is
not part of this mailing list. but just for information) and everything
is working fine except that the received packages are not intact
(receives as many errors as packages beeing send)

to my question:
how many bits or nanoseconds are lost in the real twister after it has
gone through it (TP->air->TP).
i'm currently at a loss of 140nS. anyone know if this already too much?

thx in advance for your awnsers=)
greetings

Message-ID: <20060729142349.GA5397@kestrel.twibright.com>

I was in IKEA and found in the kitchen part an interesting little cup to put
colophonium in. It's meant as a salt and pepper box. It's a shallow heavy
little round cup made of stone. There are two in a pack, one white and one
black.

The advantage is that it's not going to travel around the table.

No

The change is substantial and systemic to the transmitter.

Yes, you can cluster the bandwidth of Ronja the same way as wired Ethernet
would be clustered. There is no limitation in Ronja that would prevent this.
