Hi Charlie..
What combination of versions and boards are you using to get this to work? So far, I downloaded 3 versions of the timerboard and can't match a schematic or parts placement to them. I have 3 different timer boards etched and am wondering which one to waste the parts on. I think we should group the correct schematic, board layout and parts placement with it's match. Is R7a actually a jumper if not using the IGBT output? Is R-9 actually not on the timerboard but on the HV board input line for the MC34063 chip? Seems that way to me... Let me know.
I am about ready to buy an RC-Excel ignition if this doesn't work. I have accumulated about $75 in parts to build these boards..just doesn't seem justified for some reason does it? If I could match the three items together so I know what I am building I'd be fine. I am very frustrated on this project. I built the RS232 board, hooked it up and it immediatley fried the chip...along with the com-port on my computer. It's not going well this time around.
Hopefully, I'll have it all sorted by the end of this weekend!
