RE: CDI gr8flyer55
Yes, that's how I originally got the hex file posted, should work for the ASM file since it is just text anyway. I am glad there are many ways to accomplish these tasks. What we actually should have though is a dedicated web site for these projects and related files. Looking into a way to do this for free with password access.

RE: CDI gr8flyer55
Good idea John.
Now waitingfor Nyemi flowchart/instructions.
What about your HV module , is also open source ? which Ignition coil you use ?

RE: CDI gr8flyer55
The hv module is coming. Ignition coils I use are
mostly the Zenoah grey coils. Picture of that coming tonight when I get off work. Schematic for ignition is being drawn up also. Been busy the last week with work , I have 2 jobs. Also, a hex file for 4 strokes is in the works.

RE: CDI gr8flyer55
Hi John,
Please copy here also the ASM file for 4T engine when you will finish it.
In this way we can see the difference between 2T and 4T and to learn something new
Thanks

RE: CDI gr8flyer55
Another new item being added in the lineup is a small static timing light to go between the hall and ignition..Works with mine and also C&H and Rcexl.. Boards available etched and drilled with parts as a DIY kit. You supply wires and connectors.

RE: CDI gr8flyer55
Since we can no longer post pictures or files reliably on RCU, I looked for another public access area to do this.
There is a program called Drop Box which I will try to use. Testing it today and if it does work as intended, the schematics and parts layout files will be posted there in either Zip format or PDF format if I can. RCU used to be easy to work with, but lately it seems that their server has slowed to a crawl, making it a real pain to even log on. If it is repaired at a later date, posting can be resumed. I have numerous pictures, videos and text files to add to this forum but have held back for 2 main reasons.
First was the file upload problem, and then the derogatory comments from some forum subscribers. Hopefully the latter has ceased, thanks to the moderator.
I will post the link today for my Drop Box location. Hope this works!
John
First link is for a PDF file to etch my CDI board..should be the correct size as is..
Second link is for the hand drawn schematic with parts list for the cdi board
Third link is the parts layout for the board. Jmp is a jumper at those locations for +power and -ground.

RE: CDI gr8flyer55
Let me know if the links in the above post are working.. If so, I'll add more.
This link is to a PDF file of the original construction article which appeared in RCM magazine. Alot is explained in this reprint article which would have taken me alot of time to retype.

RE: CDI gr8flyer55
This is the CDI mini LED timing light. There are only 4 parts on the board, easy to construct on perfboard or a PCB.
Resistor R-1 is a 1k ohm 1/8 watt. R-2 can be a 370 or 470 ohm 1/8 watt. Q1 is a common 2n3904 or even a 2n2222 transistor.
The LED is anything you have on hand that is bright enough to see in daylight, preferably red...I used bright yellow.
This circuit plugs inbetween your hall sensor and the ignition module. Works on CH, Rcxel, and my CDI. Does not allow the plug to fire but shows you when the magnet is under the hall sensor. Rotating the engine in the direction it normally runs will light the Led when the sensor is triggered by the magnet. It will stay on until the magnet leaves the sensor, and at this point where the light goes out is where your timing is set to fire.

RE: CDI gr8flyer55
All links appear to be working ok. Nice work on the small boards. How do you do your toner transfer for your boards?
Just that it looks to be a very fine finish. Saw an article here a while back on converting an A4 laminator for toner transfer on PC boards. The particular model is not available anymore and so I went in search of a replacement. Found one at Officeworks here in Australia, stripped it down and looked at possible ways of converting it and saw it was a possible replacement. Presently away from my workshop for a few months, and yesterday I see another article and they have used the model I selected.

Website for anyone wanting to take a look. They have other interesting articles there as well.

RE: CDI gr8flyer55
Hi Bluejets, thanks for checking the links. I appreciate it.
My toner transfer method is easy. I use an HP Laser printer, and print on glossy photo paper, then iron it onto the pcb. Soak in water till the paper is saturated and peel off, ready to etch. Works great.

RE: CDI gr8flyer55
I use HP laser printer as well after finding out that Brother toner does not re-fuse. Also heard about glossy photo paper but every one I tried has failed to release when soaked in water.
Presently use blue toner transfer paper but it can be rather expensive here in Australia.
Once I get back and do mods to the A4 laminator, hope to get some consistently good results.
Can you tell me what brand and/or part number for the paper?
....Thanks
Jeff

RE: CDI gr8flyer55
I have been using Royal Brights paper with good results as you can see. Also tried Epson photo paper, but it seems to have a waterproof vellum on the back that sticks to my iron. In order to use it, after printing I split it apart at a corner and peel it off before ironing. Works really well that way since it is then only half thickness, allowing heat transfer very quickly of the toner. It comes off easily with a 5 minute soak in warm water. Hope that method works for you.

RE: CDI gr8flyer55
Ok...Royal Brites paper doesn't seem to be available here and with both Royal Brites and Epson, there are about 10 different types of glossy photo paper.
I have tried some in the past that people have recommended, and as the exact same type was not available, I settled for what the sales people said was "the same thing". However, did not work at all.
Could you be a bit more specific with the paper number?
Thanks..Jeff

RE: CDI gr8flyer55
I wish I could give you an item number but I have bought a number of Epson printers over the years and this paper was in the sample starter pack from those printers. Just a ploy to get you to buy their products I presume. The best stuff I ever used came from a computer show, was cheap so I bought some. Had it for at least 10 years in a box until we moved to this house last year. No brand name on the box.

Nice work...especially like the neat job on the torroid. All working ok now....????
I will be back in Aus in a few weeks so if you need a hand with the schematic, drop a line.

RE: CDI gr8flyer55
Hi Jeff.
Yes, everything works beautifully for me now. I really like winding the toroids, kind of relaxing and it gives me a sense of pride to be able to make everything myself and then have it all work so well makes me smile. I love hearing that first spark from each and every unit I build. If I could only do one thing till I die, this would be it!
Could you please PM me with your postal mailing address? I want to send you one of these new boards. I also will email you the file I made of the schematic for you to rearrange making it easier to view for forum users wanting to give it a try. I realize now that there aren't many people interested in my DIY ignition, but on the odd chance there are some individuals who are interested in it, I want to make it as easy as I can for them. My aim is not to be in competition with anyone trying to make an honest dollar in this area of the hobby. All I am trying to do is provide a good working design, easy to build and have something that is completely repairable.
Thanks for the reply...
John

Hi John,
Verry, verry nice job,
A simple and ,i suppose, a stabile CDI.
Can you verify max. working RPM ? (w/o software limitation).
Please post the pdf file.
Best Regards,

RE: CDI gr8flyer55
Hi Dino.
At the present time the software limitation for top RPM is set at 9973. It is alterable in the source code however. We must ask Nyemi to raise it to whatever you will need it to be and then it will have to be recompiled to a new hex file.
My neighbor and I are going to make a few changes to it also, so when we have the new edited source code it will be posted for sure. I'm looking forward to getting this done also, since I have at least 24 of these timer boards ready for the new updated hex file. I know that some users require it to function up to 20,000 RPM. This is one of the goals I hope to accomplish. My CDI ca handle the increase in RPM easily since I have tested it past 25,000 RPM and it still functioned well. It is only the timer software holding it back. As I tested on most of my converted weedeater engines, they never go past 9,000 rpm so it was fine for them.
I would suspect boaters and some R/C car hobbyists being the high RPM requirement crowd, would benefit from the change and I also have a few of those models. Nyemi, if you are reading this post and can you make the higher RPM change for us, please let us know when you are able to find the time for this much needed update.
Thanks...

Hi John
I congratulate you. Your building ignition.
Great job.
High RPM=High Spark
I adapted, 400V inverter.
Link:www.ebastlirna.cz/ftp/index.php
Spark energy:75-100mJ
No, overheating components.
Inverter Efficiency: 88-90%
Wide supply voltage range:7-14V
Zero Voltage Switching .
Small number of turns in transformer.
Little money, transformers
I works perfectly.I will help you after the building.
