Justin,
I think your starter kit sounds great, although I will not require the kit
- as I have all the parts on there.
I have some tact switches here that fit breadboard - id be willing to
donate enough to give everyone mabey 2 or 3 each if that helps, also any
resistors that are needed (I bought the stock of a closing down pcb fab
house about 8 years ago) so i have literally millions, if you can let me
know what values you want to include. I can also spare a hundred or so
100nF(104 labeled) bypass caps (everybody needs bypass caps right :) ), and
some 10uF electrolytic caps each (thats what I dot about my boards).
Let me know if any of this stuff is useful and i'll bring it along next
time. (someone else will have to divide it up into poly bags for each
person)
Thanks
Graham
