They were unable to accept my Gerber because it was using negative subtract operation. The Gerber generated by PCB AFAIK conforms to Gerber RS274-X standard so I then went to Pragoboard, which is now manufacturing Ronja boards in considerable quantities for many people. I don't have experience with any other PCB manufacture company. CL< > ja si budu nechavat delat 3xtwister a 3xTX. Ma nekdo zajem? > > V.

When I was developing the TX I tried first a circuit with transistors which was distorting the signal horribly.

TI 1000pc price is 6.6$/pc:-) anybody? I tried AC. Works fine. The TX with AC oscillates. I don't know if it's because of AC or if HC do this as well, but the TX design is definitely bad.

But this idea implies, that users of the Internet know each other and buy such a proprietary thing to communicate. Got that idea? Ronja is generally a data link. You cannot expect, that one end is connected to the Internet and one to somebody's home. Common usage of ronjas is to enhance 11Mbps HD links of Wifi to 10Mbps FD. Then I am pretty unsure, that APX10 is so strong, it can handle 1Gbps - even 100Mbps radios are rare and pretty expensive. All you can get from thing like APX10 is 54Mbps HD(theoreticaly) - so you cannot use the full potential of ten ronjas (even if they were each connected to 10Mbps Internet line - which makes no sense here). PLEASE figure out that generally a data link has no conjunction with Internet. If you want to use the full potential of more Internet connections, I offer you this scenario: Make a central point among all the points you would like to connect. Make a link from each node to the cetral one. You can use Ronjas to make that connections. Then in the central nodeyou will be able to get Number_of_ronjas*10Mbps bandwidth to the Internet. This implies, that all nodes are connected to 10Mbps Internet. Each of that nodes is then (approximately) capable of 20Mbps Internet (10 from ISP and another 10 through Ronja). I hope I explained it well.

Because the preemphasis is increasing the time the LED is shining and when the noise is broadband, the increase gets bigger. The solution is to throw away this (my ;-) ) crappy TX design and replace with Nebulus just with the difference that infra LED is replaced with HPWT-BD00-F4000. Looks like the current red TX is unsuitable for analogue retranslation. Thanks for pointing out.

If you have only 1 point where you want to get the Internet from, then this will be impossible, because all the 10 ronjas would be seen as 1 bright red light, and the receivers would get only interference as input. But you could use _very_ expensive filters to make a frequency division.

You would have to install them with several meter separation to prevent crosstal (depends on communication distance). And then connect them into some switch or PC which can do link aggregation.

It's probably using some kind of data compression. On-the-fly compression is not suitable for high speed links like 10Mbps or 100Mbps because it: 1) takes lots of CPU 2) increases latency 3) makes packetloss worse.

Jenom pro uplnost dodavam, ze pri mych zkusebnich testech bylo potreba RX zastinit zcela, aby TX zacal svitit silneji.

That's interesting. 2N3904 is a switching transistor and has a nominal transition frequency of 300 MHz, but has very slow switching times (32ns and we need 8ns rise and fall time for 100Mbit, and 25ns for 10Mbit ) BC547 and BC847 has a minimum transition frequency of 100MHz, but I saw it in many RF schematics as power amp stage. So it is worth a try. Maybe your problem was, that you drove the transistors into saturation, or switched them off completely. Then you have much more capacity to fill up, and this causes distortion. If you provide a bias current and only modulate the current as like as it is used in laser circuits, the performance could get better. Did you try this? I bought a good second hand Tektronix 100MHz Oscilloscope now, and have seen how MLT-3 and Manchester coding really works. Simply said: It is a beautiful signal. I'm in love with it :) (Another beautiful pattern is a DVD HF-signal. That's, why people get electrical engineers :) ) I bought a lot of different RF transistor types and will make some tests with simple amplifying circuits. I think I find a useful 1-2 transistor solution for the TX. Maybe the bc547 or bc847 works as well. This would be the best, because of its cheapness and it prevents oscillating at high RF... Good news is, that I got 4 pieces of 8x DVD burners. All red lasers are working, and that means, that 150mW optical power can be achieved, if necessary. If I collimate 100mW into a parallel beam of 90mm diameter, how strong is it for human eyes (5mm pupil diameter)? Can I calculate such that: Acoll = 90*90*pi (mm2) Aeye = 5*5*pi (mm2) Plens = 100 mW Peye = Plens * Aeye/Acoll = 100 * 5*5*pi / (90*90*pi) = 0.308 (mW) And that's far below the 1 mW limit...maybe... Why exactly didn't you use cheap lasers as emitters? (OK, the driving and APC is much harder work, but laser can be collimated more easily) Whish me luck to have the time to do the work...

Did you messaure it direct on UTP cable or on inputs of TP transformer on NIC? How does signal look on end of 100m long UTP cable?

Inteligentni clovek muze delat umyslne trolla blbce a blbec se zase muze nechtene chovat jako troll. Navic i kdyz se zakaze trolling, tak inteligent nasimuluje debila takovym zpusobem aby se to nedalo prokazat (z jinyho e-mailu). Takze podle me je jedina obrana pasivni rezistence - smysluplne otazky korektne zodpovedet, nesmyslne pouzit jako inspiraci pro nejakou smysluplnou predstavivost a na tu odpovedet. Jestli se snazi utocit na projekt Ronja tak zjisti ze timhle zpusobem to nejde a vysere se na to - zere to prece jen cas ty hovadiny vymejslet pokud to dela umyslne.

Tuhle uvahu jsem ale nemel nicim podlozenou a jak je videt, tak jsem si experimentalne overil,ze to byla blbost ;-). Patch v podobe pilky bohuzel uplatnit nemuzu, protoze dotycny strom se nachazi na pozemku souseda a je to jablon, co celkem dobre rodi. Reseni je uz ale tak nejak promyslene - je mozna i jina trasa,bohuzel budu muset delat nove drzaky na obe strany. Ohledne RSSI - taky jsem is rikal,ze by asi melo byt vyssi, ale problem vidim v nedokonalem zamer. systemu - drzak na jedne strane je dost pochybny a trosku silnesjim vetru se houpe. Nutno dodat,ze to nemel byt drzak pro trvale pouziti-jen pro otestovani funkce spoje. ZKusil jsem i snizit citilvost Rx - nahrazenim C ktery je mezi 4 a 11 pinem NE592 seriovou kombinaci R a C dle FAQ na webu Ronji, ale RSSI jen dale klesalo a na prenos to nemelo zadny pozitivni vliv.

Sorry, I'll get a camera only in a few weeks. I measured it directly on the end of a 0.5m cable, with 100 Ohm termination resistance. I hope I was correct in choosing this. The cable was connected to a router called "Alcatel Speedtouch 510". Signal levels were +-1V with no termination, and +-0.7V with termination. Unfortunately I dont have a 100m UTP cable, but I dont think, that it is necessary to make a measurement with it, because today routers are getting cheap ... Take a look at http://de.wikipedia.org/wiki/MLT-3-Code You can see a single shot of the signal only with a DSO. With analog scopes you can only see the "Eye-pattern". This means, you can see the hold levels, and the transitions of the signal. This is far enough for doing test measurements. bye, Martin From bob at viacel.com Wed Feb 15 17:13:35 2006 From: bob at viacel.com (Bob Miller) Date: Wed, 15 Feb 2006 12:13:35 -0500 Subject: [Ronja] Ronja Digest, Vol 34, Issue 10 In-Reply-To: <002201c6321c$77cf3860$d203a8c0@diablo> References: <20060215011616.98523.qmail@web53407.mail.yahoo.com> <43F28997.7090201@viacel.com> <002201c6321c$77cf3860$d203a8c0@diablo> Message-ID: <43F3613F.30102@viacel.com> 1 Gbps is fine and 500 ft is fine.

It's a fact, that if i look only at a tx pair, then there are only "fast link pulses" on the line. A saw those, too. I have circumvented the problem of getting real data by feeding the tx signal back to the rx input of the router. This means, the router thinks, he is seeing another NIC, and is doing the autonegotiation. Then it begins to send idle data in MLT-3. (it continuously sends the IDLE code, but it is scrambled, so it just looks like other data.) This IDLE stream is why I think, there is no need for a twister board (OK, a power supply board will be necessary) Bye, Martin From seligr at sh.cvut.cz Thu Feb 16 12:30:10 2006 From: seligr at sh.cvut.cz (Petr Seliger) Date: Thu, 16 Feb 2006 13:30:10 +0100 Subject: [Ronja] Spravna funkcnost spoje, pokud je v ceste koruna stromu In-Reply-To: <980.3887-13744-1545694340-1140008545@seznam.cz> References: <980.3887-13744-1545694340-1140008545@seznam.cz> Message-ID: <1140093010.43f4705247d6b@desitka.sh.cvut.cz> Zdar "ZKusil jsem i snizit citilvost Rx - nahrazenim C ktery je mezi 4 a 11 pinem NE592 seriovou kombinaci R a C dle FAQ " Tohle je blbost, pokud je RX prebuzen tak to vubec nepomaha.

Yes. The story which lead to this is as follows: Stephen Hawking was watching the TV and saw Shaun White winning gold on snowboarding halfpipe. He says "I suddenly felt angry - I virtually cannot move and this brat gets a gold for a speed and tricks which are funny when compared to speeds and tricks that can be achieved where quantum gravity kicks in? Just because he started boarding at 6 when I was already cramming physic textbooks into my head? And he's American and I am British! I am dealing with quantum gravity day by day, so I am gonna kick his ass!" Stephen Hawking initially called Burton if they have a board for wheelchair people. They said they can do anything but they don't have an idea what such a thing should look like. Stephen then googled up some board basics while still hanging on the phone and then dictated into the phone "I need a +/-20deg duck stance, a bit wider, and an extra plate that will keep my ass from falling off the board. My stance will be a real duck, do you understand? And then mount two aluminium bars next to the bindings which will allow me to control the board. How much is it?" Burton: "That's for free our secretary just figured out on Wikipedia that you are a very famous person so we'll give you a sponsorship. But you have to change your name to Stephen Hawk. And go into X games." Stephen: "No Prob, Hawking is long anyway, it made problems in my speech synthesis computer. And I can do Y and Z games if you want as well, I don't care, I was always good in physics." Then Stephen got his board and went to hit the bunny slopes. But, as he says: "After one blue run I went directly to a yellow one because I immediately saw I have a natural boarding talent. I was doing linked turns immediately. I also fixed the lift, they had the phases in the motor wired wrong so now it's going faster." But because of low gravity, riding was actually much easier than normal board and Stephen was still feeling bored. "The yellow slopes were still slow so I tuned the board a bit. First I sharpened the edges under electron microscope which I found in the garage. Then I greased the baseplate with Johnson baby oil and finally dipped the board into liquid helium. When the board hits the slope, it freezes the snow as well and under this supraconductive temperature, the board with the slope form a Josephson pair. The Johnson baby oil then assures that the interface between board and snow forms a Johnson junction, which allows the board to glide suprafree. With this I finally was able to reach speeds where controlling the board wasn't a piece of cake." Then Stephen practiced his technique a bit but then came a problem: " In high speed, I mean a serious speed, not that joke that the redheaded pubertal kid was showing in the TV, say 0.3c and higher, I got serious problems with air resistance, it was causing vibrations and burning the laminate. I called Burton if they have something that withstands 26,000 degC but they said they are sorry that I am off by more than one order. So I had to figure out some alternate trick." Stephen figured out the wormhole idea. "I keep the downhill edge about Planck length above the snow. Because of classical mechanics, I should risk catching the edge and smashing my face really hard. But I know the board actually goes thanks to Heisenberg uncertainty principle into a mixed quantum state where one half of me is being kicked ass all around the mountain by the catched edge and the other is riding still at kickass speed. Then I abruptly stop and the other half of the entagled system fails to react quickly and separates. But the energy of the separated system is too high for the space to hold it. The space-time caves in and forms a worm hole. This inverts the probability matrix and instead of my ass being kicked, I am the one who kicks ass - and I can do wonderful airs or get almost anywhere in no time. Man, I am not doing airs, I am doing spaces! With a tiny twist of the board, I can choose if I check out the weather on Mars, Venus, Jupiter, or Alpha Centauri! I just have to hold my breath in that empty space." Stephen also brought some new research into technical snow preparation: "Man, the snow on Mars is wonderful! It's made of carbon dioxide. The finest powder in the world! You can do fucking hell of a carving there. Try it out and you won't believe!" This is how Stephen Hawk(ing) invented the wormhole travel - and we just added Johnson baby oil and liquid nitrogen into Ronja and now it does 1Gbps over 100km. We'll try liquid helium where the supraconduction should be better and we should get 1Tbps over 1 light year easily, with cheap parts for 100USD!!!! Stay tuned, and buy Ronja boards AS SEEN ON NATIONAL TV!!!! "I also started doing skatepark on my good old creaky wheelchair, but it's a piece of cake compared to what I can do on a snowboard!", said Stephen Hawk. http://www.phreakmods.sohounion.com/pics/hawk.jpg CL< > Everyone know that light from death star travel throught space houndred > years as far as it can.

To have upgrades on Ronja we would have to implement some onboard computer which could then be upgraded by overwriting the flash ;-) But the idea is not bad, the computer could measure temperature, signal strength and ambient light.

Sender refused by the DNSBL dynablock.njabl.org ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Maybe he's reading the Ronja mailing list. Or someone who isn't on these blacklists will forward it to him. For the others warning - if you ask me personally and then your SMTP server refuses to receive my reply, you won't get the answer. With 50% probability, my reply to you will be refused if your SMTP is using SORBS DUL blacklist or dynablock DNSBL. If your SMTP is using these blacklists I recommend you to permanently disable them. If you cannot change the config of your SMTP I recommend to switch to a different e-mail service.

Podle mych mereni zacne BF998 orezavat vrsky pily a NE592 to nasledne chybne intepretuje jako neexistujici pulsy. Sice pri rozkmitu signalu nad cca 0,5V na vstupu NE592 nastane jiste zkresleni v dusledku blbeho zakonceni jeho vystupu ale limiter s tranzistory si s tim poradi.

Sice pri rozkmitu signalu nad cca 0,5V na NE592 limits at 4V. Since it has amplification of about 400, that means 10mV of input signal. BF988 will not limit at 10mV.

I was looking for a way to get a broadband connection to a friend of mine ( there is no such connection available for him but the village next to it has). So i found out about Ronja.i thought about building it but i couldn't gett all required parts. so i decided to build my own small light-communication device from scratch. using the serial interface and managed a 20kByte connection for really few money (less than 10$ for electronic). but the receiver sensibility wasn't what i hoped for.i ended up making this a school-project (good excuse to use the e-laboratory from time to time). In the end my circuit became more and more like the Ronja's receiver. but the part with the capacitor bugged me. dont worry^^ i wont build such thing and sell them =)I'm one of those open source guy's myself. just thought there might be a way to simplify the circuit and improve performance. bdw. anyone out there who knows how commercial receiver stages are working?... would give a hell to disasamble one for free^^ ahm jeah sorry for these long posts. but there are a lot more tings i dont really get: Q102 and Q103 are connected to bild a differencial amplyfier aren't they. why not use a NE592 equivalent IC with 2 op-amps in it and spare this part of the circuit (or is that much power required to get the signal through the cable?althouh its couppled off). why using a lot of ic's in the transmitter circuit to drive the led instead of one or two transistors(maybe fet). (most of the twister design is still a riddle to me) i know these questions might be stupid to ask. but after 2 month searching myself i really like to know.i think i'm lacking real-life experience when it comes down to electronik and i'm shure the desingers had its reson to make it this way, so i like to understand the problems and solutions. sorry again for my endless writings and thanks in advance for any reply From seligr at sh.cvut.cz Sun Feb 19 21:34:54 2006 From: seligr at sh.cvut.cz (Petr Seliger) Date: Sun, 19 Feb 2006 22:34:54 +0100 Subject: [Ronja] FSO In-Reply-To: <009101c6357f$8c16c8e0$d203a8c0@diablo> References: <200602191559.10293@centrum.cz> <009101c6357f$8c16c8e0$d203a8c0@diablo> Message-ID: <1140384894.43f8e47e5a130@desitka.sh.cvut.cz> Safra to mam co dohanet.

The idea is simple, but I don't know whether there is not something, that I missed. Idea: Transceiver converts ethernet to serial optical communication, which can be handled much more easily then - there would be no need to use twister or something like that.

The original question was, whether it would be possible to replace Twister with some commercial FO transceiver. You seem to be talking about forcing cheap wired-ethernet switches into full-duplex mode, thus allowing them to be used with Twister. Or did I miss something?

What distance is the maximum (without Optics) ? Have you ever thought about (e.g.) Frequency modulation ? For example you could use 1MHz and 2MHz for this purpose. I think, this should make the signal a lot more resistent to other sources of light. Some Mainboards can also drive the 2nd RS232 as IrDA. Maybe this would be easier.

What distance is the maximum > (without Optics) ? what distanve are you looking for? =) like i said, i haven't made any field tests. without optic (i still have trouble getting cheap lenses), with cheap led (used one of my pc-modding parts) about 20~30cm with a ugly,old and half-broken laserpointer.. more (my room wasn't enough)^^ would guess it's enough for crossing a street.(no garantue on nothing) and these test where made with a older receiver design (today i wonder why it worked at all^^) and it only had a single amp-stage and the diode current had to drive 2 op-amp inputs (!one needed 12?A to work!) -i know.. really bad design^^ todays version !should! bring a huge increase of range. > Have you ever thought about (e.g.) Frequency modulation ? > For example you could use 1MHz and 2MHz for this purpose. > I think, this should make the signal a lot more resistent > to other sources of light. jep i thought about it. but as long as the other light sources don't flicker with more than a few kHz there is no real need. my neon-tube above my workspace was no problem for the receiver. streetlamps shouldn't be one either, hot air flickering..dont know but might be same as with modulation. dont really know how much better the results would be, but atm it's working and it's really cheap.(clear-red plastic should also do a wonderful job :D ) adding a extra modulation (and demodulation) would result in a larger circuit. also gives you problems with transmitting led's (i already noticed some of my led's don't transmit clear above several hundret kHz) receiving data from a sunset isn't a good idea anyway ;) > Some Mainboards can also drive the 2nd RS232 as IrDA. almost same thing (would spare 1 ic and speed would still be rs232 maximum given by your mainboard). and only a few boards can do this=). i like to keep the rs232 specs so the user just plugs in&fine with no fear of killing his circuit due to -12V. there are more boards with an onboard IrDA controller. one the receiver stage is fine i'll start working on the USB-part. hollydays started and i found out my neightbour has an old oszilloskope. good news.so stay tuned.

The idea is simple, but I don't know whether This is actually quite simple work. The main problem faced by Ronja is not system complexity, but physical conditions. So the actual "dirty work" is mechanics, optics, low-noise front-end, good modulator, shielding, design from low-budget easily obtainable components, builder friendliness, overall robustness, and durability.

Less than 200mOhm? At room temperature: yes, quite likely. You don't say what dielectric (X5R,X7R,Y5P etc). This can make a large difference, especially wrt temperature sensitivity. Depending on the application, microphonics may be an issue. For a clear illustration, see: http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1003,C1040,C1019,P2168,D1258 . Go to page 10, have a look at figure 4 (the scope plot). The ceramic caps on my 75W IR pulse laser driver board buzz like an angry wasp when I put the laser on autofire. For a transmitter that's merely annoying, in a receiver the coupled noise may well scramble bits. What are you using it for ?

Please put it into the gEDA user manual as example procedure so that inexperienced users can draw a correct SMD footprint in 10 minutes and not an incorrect one in 1 hour.
  • Set grid to unit according to source drawing
  • Draw the pads. User CTRL-M to measure on component layer
  • Draw the silkscreen with 0.2mm line thickness on silk layer. The outline of the component is the outer edge of the silkscreen (not the center of the line nor the inner edge).
  • Draw an alignment cross in the future component reference point using two rectangles placed on "unused" or "unused1" layer
  • Check all dimensions according to drawing using CTRL-M
  • Go over each pad, press 'n' and enter number of the pad.
  • Select everything
  • Copy selection to buffer
  • Click on the alignment cross
  • Convert buffer to element
  • Set the grid to maximum
  • Place the element somewhere apart from the original drawing
  • Press Q on pads which shall be square
  • Go over every pad, press 'n' and enter the number again.
  • Now you need to change soldermask for all pads. Always select all pads with the same thickness (measure using CTRL-M). If you are working in milimeters, issue then "changeclearsize(selectedobjects, thickness/2+0.1mm)". If in mils, "changeclearsize(selectedobjects, thickness/2+4mil)".
  • Unselect all
  • Turn off soldermask
  • Turn off silk
  • Select component layer
  • Draw a big rectangle over the footprint
  • Select all pads
  • "changeclearsize(selectedobjects, 0.35, mm)"
  • Remove the big rectangle
  • Turn on silk
  • Press 'n' over the silk and enter for resistor R000, capacitor C000, coil L000, transistor Q000, soldering point T000, diode D000 etc.
  • Place the label suitably near the footprint
  • Press 'd' over the footprint, check the numbers, press 'd' again
  • Select the whole footprint
  • Copy selection to buffer
  • Click exactly over the middle of the diamond
  • Save buffer elements to file, enter the filename
  • File, Quit Program, OK to lose data? OK.
  • pcb
  • Load element data to buffer
  • Enter the name of the file

Put 3 of them between the shielding of coaxial signal cable in RX and ground. As close to the point where the cable leaves the shielding box as possible. Keep the wires short. Do the same with the point where the shield of the cable leaves the Twister shielding box. Solder it from inner side box from the end of the stub to the shielding metal. As short as possible, 3 of them in parallel. You may need a powerful soldering iron for this. Or help yourself with a candle. I have just measured it and it reduces the residual signal on the line down to 1mV. It doesn't work with tantalum or electrolytic capacitors - they have too big resistance. Also doesn't work with 100nF capacitors - they have too small capacitance to cover the low 1MHz frequency.

Jeste je potreba vymyslet nejak rozumne mereni RSSI, v te rychle verzi je to pres sledovani proudu fotodiodou a je to moc slozite a reaguje to na okolni osvetleni.
