Sure Aaron, It's always good to let your own thoughts over a certain circuit rather than just "copying" an existing design. I very rarely use breadboards, I find it easier to modify a concept board (like the one you already have) rather than building up everything on a breadboard. But yeah, maybe that's just me :-).
I am looking forward to a kit. Michel On Sep 14, 8:06 am, "[email protected]" <[email protected]> wrote: > Hi Michel - That is a great idea.
