It seems the board works fine so long as you don't hold on to it. Which will never happen in a real life situation.

I'm not building any more ignition board circuits. Tired of all the wasted parts and time involved. If someone comes up with a better board that is both more efficient and more powerful, so be it. Use that board. I am not in this to be a competitor, just offered what I make. I have hundreds out there that are working fine with little or no RFI problems. The stronger the spark a board produces, the more chance for RFI. There is a cut off point for performance versus RFI problems. I don't care to argue this point anymore. If what you build is working, then use it.
I agree John with the RFI, been there done that. Beside I thought your ignition was originally designed for doing conversions on wacker type motors, which very rarely go over 10k rpm. So don't fix what ain't broke.

We have a timer board and various HV board designs to choose from as evident by the posted schematics. I would rather see new ideas with off the shelf parts available than have someone condemn the work Rob and I have done in getting this ignition thread started. There are those who seem to forget, this information was all given for free to share a good thing with fellow modelers.

Just my 2 1/2 cents worth

Yup, it's open source, take what is given and make it your own. I believe IHMO that because it is open source everone should have a different setup, that is how we learn.


P.S. I'm still going to use the 2 you sent me, whenever customs is finished with them.
