Status: offline 		John,
I changed the curve by changing values in the table between 1600 rpm and 7500 rpm. With the values I put in, this resulted in the curve changing to a dead straight line between the 2 points. If it works i.e. changes the delays like I think it should, I give you a rundown on how to do it.
Doesn't work by trying to drag the curve as far as I am aware.
Transistor, I did not use 2N4401, I think maybe BC547 so that might be why I showed it a-about. I thought I checked that..mmm.ok
Either way, I did have it connected the right way but i will change it to show your transistor.
Ok..cheers...Jeff

Status: offline 		Re-transistor...yes, just checked, used BC547 so thats why in the pic of my board, Q2 has flat the other way. Connections are correct though.

Status: offline 		That's what I figured you did Jeff, made a substitution and it worked for you. Overlay looked excellent!
Is it ok to post the files after I convert to PDF format?
I believe everything else is correct in all the other files. Let me know when you have the edit sequences perfected for the curves. I'll test that here on my plane to make sure it'll give the performance figures I am expecting in idle, transition and top rpms. My test engine (a 25cc weedeater engine) reflects changes pretty well when testing.

John

Yes, I think a few might be wanting to see your successful project.

Status: offline 		I will try to post files here. Been having alot of trouble lately even logging onto RCU. The software will be posted first, then the PDF etch files etc.

Status: offline 		Hello Ustura...
I do have the schematics for the boards, and I will post today if RCU doesn't give me any more trouble uploading files. I just have to convert them to a format it will accept here. I have a parts overlay picture that I will try uploading first, then the etch file for the combo board, and a parts list. Nyemi has made available the software files for the ignition. Thankyou Nyemi !!!
Without his help, this project would have not been possible. He has done an amazing job over the last 2 years with the software design and constant updates. If there are any questions on the software, direct them to Nyemi. He has been very helpful to everyone needing help with the advance curves.

John

Status: offline 		Ustura,
The coil for the hv was described somewhere before but hard to find I think so I will re-post details.
The ferrite toroid John used was ... Ferroxcube 768T188/3E2A
The size is .................................. 12.7mm(0.5”OD) x 7.2mm(0.285”ID) x 4.8mm(0.19”H)

I used one from Farnell here in Aus. and the part number is TN13/7.5/5-3C90
Web site here......... http://au.element14.com/ferroxcube/tn13-7-5-5-3c90/ferrite-core-toroid-3c85-13-25mm/dp/178504?Ntt=TN13/7.5/5-3c90

Windings are of course enamelled copper wire.
L1 = 15 turns 26 gauge (#26)
L2 = 6 turns 36 gauge (#36)
L3 = 400 turns 36 gauge (#36)
Keep the start of windings L1 and L2 marked because the orientation of these two windings are important to the operation of the oscillator.
John used a "stick" with the wire wrapped to do his winding of the toroid and although a bit painful at times, it does work well.
If I remember, the "stick" was fairly narrow with a notch cut each end to hold the wire, and it was about 150mm long. You will have to work out how much wire for the 400 turns as it depends on your toroid core dimensions.
Jeff

If you swap one of the primary windings end for end, should work ok. (i.e. swap start and finish of winding L1)

This is assuming you have no shorts or damage to windings. If you look closely at the layout diagram that John supplied and you have wound the coils all in the same direction, you will see the start and finish of each of the primary winding positions are marked.

If you click on the pic and download it, then open with windows picture and fax viewer, you can magnify the drawing.

Status: offline 		The system works with the parts listed.
The program was written for 12F683 chip.
If you want to experiment with other types, then you will have to work it out for yourself.
The hall sensor I used was Allegro uA3240 .....unipolar.... not made anymore but I think A1120 is a replacement.
The last thing you want is a hall effect that "latches". The program looks for (I believe) the trailing edge pulse as the magnet passes.

I would say by the look of this the 12F675 is nowhere near compatible.
