Sorry for my poor understanding Bigboat (the late hour also adds to that), let me see if I got it right:
The CDI which you and JMJ developed (the CDI featured in this thread) is the CDI which has more options, cheaper hardware, better, less buggy software, excel-programmable, etc. You made the hardware, JMJ did the software. Did I got that right?
A friend of mine is electronic, so if I start the project I'll try not to bother you with questions about components!

See you!
