RE: Complete new CDI - website open
I order two different USB to TTL convertors on Ebay. Most computers don't have RS232 any more, only USB. With plastic cover and ready to use http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=170502874817&ssPageName=ADME:B:EOIBSA:NL:1123 PCB http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=170484687886&ssPageName=ADME:B:EOIBSA:NL:1123 RS232 cost less, for only $2,5 with shipping. The programm can handle both convertors, USB and RS232. BTW, the commercial CDI use the 3V3 option from the USB to TTL to power the pic....not the 5 Volt like the old pics.

If there are questions about this CDI, doit into this thread. If there are questions about the other (new) CDI, lets doit into the new thread. But wait with questions untill we release the new CDI.

RE: New CDI - opensource project JMJ and Bigboat
Hi John, I don't need the component.....I've a loot of those components in all kind of sizes. I only want to know if a opto is also a option to use ? I think a hallsensor is not acurate enough, and thats also the problem with this designe and software we use. I test some new hard and software and see the differend between a hallsensor and a optocoppler. The opto trigger every turn in the same degree, a hallsensor depent on the rotation speed. At low speed the magneticfeeld of the magnet is bigger the at high speed.

RE: New CDI - opensource project JMJ and Bigboat
Gentleman, I have a question. Why we all use a hallsensor and not a opto like they do into the automotive ignitions. http://www.elektronik-sachse.de/ZDG3/guzzi/en/instruction4_guzzi_en.htm I use for tests also a optosensor becourse hallsensors aren't acurate for testpurposes. I need a real TTL-signal and not a wave like hallsensors do. Maybe a reflection opto sensor can be use ?

RE: New CDI - opensource project JMJ and Bigboat
I like the differend tables I can use for my Kreidler bike, I didn't test the software yet. Also other users (minibikeriders, like the differend tables they can use. Where do you use the two leds for, what min and max rmp ? The only problem I see is the fixed sensor to 32 degrees. I think this fixed point must be floting, you never know where you can screw the sensor to the engine. I can't find out why 0ms or 3,5ms at wat address and when to use. Yes I want to use a puls for the HV-transformer like nyemi do.

RE: New CDI - opensource project JMJ and Bigboat
I change the code from How_eee for using it with a 16F628A. Watch out, you have to use the schematic from How_eee !!! But there are some errors into the schematic I think. The red lines are given a indication I think they are wrong. How_ee writes into the asm he change input hall to pin 1, but into the schematic it isn't.... I don't know, he itn't awnser my question, why he change the powerline to the til111.

RE: New CDI - opensource project JMJ and Bigboat
I use two programs, Layo1 and Orcad (both DOS) First I have to draw the schematic into Orcad and "connect" it to Layo1. When I let Layo1 do autoroute, the PCB looks like a footbalfeeld. I put the components on there places and draw the lines. When I draw a wrong line, Layo1 tell me it's wrong. If I draw all the lines, Layo1 can optimize the PCB. When you look around, the Nyemi-pcb is allready be done. I don't where I have see this schematic befor, but its not new. http://veyrat.perso.neuf.fr/allumage_electronique.htm http://www.rcuniverse.com/forum/m_4344316/mpage_40/key_/tm.htm# Please wait some time.....I'm not ready yet with the CDI's [8D]

RE: New CDI - opensource project JMJ and Bigboat
Why a testfunction who use the sparkfunction ? If someone can program a puls to one of test pins, you can connect this output to the hall input. With this modification, you can test the hole picprogram. Becourse there are also two testpins, its possible to make 2 outputs 300 and 7800 rpm maybe ???

RE: New CDI - opensource project JMJ and Bigboat
The frequentie depent of the engine you gone use. A Zenoah need high frequentie and a chainsaw low. I think we need 100x the rotations per second the engine run to load the capacitor(s). High frequentie giving also trouble, the transformers can be saturate. I think we must use the flybacktransformer we use now without the feedback wind. Becourse we make the PIC frequentie, the transformer can't be saturate anymore. The capacitor must also be changed, two small capacitors are faster loade the 1 big one.

RE: New CDI - opensource project JMJ and Bigboat
I see you pickup the old version of the CDI. We skip this version becourse the table-value must done by hand. You need a lot of calculation for the right timing to get the degrees. Why do you feed the TIL111 from the HV-side, this will be distroy the TIL111. The cristal can be a 4MHz resonator, cheap - small and allways working.

RE: New CDI - opensource project JMJ and Bigboat
Thats why I put transformer between **, but with a small 100V audio-line transformer we can do the job. A flybacktransformer isn't easy to make with the winds in all directions, different kind of wire and Voltages.

RE: New CDI - opensource project JMJ and Bigboat
I was see all over the years people have problems with the flybacktransformer and components. The components will be burnout if the ocsilator stops, or in some cases the flyback didn't do anything. If we take a normal transformer, something like 220/6 Volt and we put a puls on the 6V, we get 220Volt at the other side of the transformer. We can also put a frequentie on the 6Volt side we need and not we can(n't) get. At low rpm we can put a lowrate of pulses on the transformer, at high rpm a highrate of pulses. If there are no pulses from the hall, we can stop the ocsilator and safe batteries. Maybe we can put the position of the gasservo into the pic.....I don't know why yet, but it's possible. The last copple of years we learn and see we make some mistakes into the past. If we make a new CDI-concept, we must do it without the mistakes and not try to fix the mastakes.

RE: New CDI - opensource project JMJ and Bigboat
BTW, there are also some little problems with the hardware. RB0 and RB1 are switched, RB0 must be a input and RB1 a output (see manual pic). With a 4MHz intern ocsilatorclock the calculationtime is max 13.000rpm There is not only a fix for the old program necessary, but also a fix for the hardware. I think it will be better also to put the ocsilator for the HV-transformer into the pic. No flybacktransformer anymore, but a normal wind without the components to ocsilate.
