Hi all,
I've downloaded the schematics and pcb layouts from the GOMPY site and constructed it. CDI works well on the bench in test hi and lo modes and with magnet mounted to an electric flywheel the hall sensor fires the circuit well also. Can any one help though with the rotten excel spreadsheet. I've done everything as listed on this post regarding the ADD INNS for excel and still get the DEC@HEX macro problem. I would now like to be able to manipulate the advance curves but can't until I can get spreadsheet working. Also better way of contructing transformer is to use a split ferrite core and bobbin. Wind on 16meters of .2mm, 20 turns of .5mm and 10 turns of .2mm. Look forward to any positive responses to excel problem.
