One button window switch.

- You'll want a pic(microcontroler) like the PIC12F675 to cut down on your parts cost since it has a built in ADC. You may need a op-amp in there depending on how cleaver you are at coding and what resolution you can get out of those onboard ADC's.

That pic is only 8-pin. Wouldn't you need something with a few more inputs to handle the two (or more)? Are you implying that one pic per window/switch be used?

- power supply/filtering. You'll need a hand full of parts to protect the pic and filter the power.

I assume this is for preventing spikes? Also, in the case of the power dropping during starting, how would you implement a protection circuit? What size cap would be considered too big in that scenario?

- custom PCB with wide-ass tinned traces, case, wiring harness, connectors.

Can you explain why? Just asking, as I'm just getting into electronics.

If one were to, say, implement ptp wiring, would the guage of the wire effectively act similar to the wide traces? I mean I might use perf boards for some stuff, but I'm not too keen on using eagle to design a two layer board and then pay the money and wait the time for a one-off board to be made. If I was dead-set on using ptp/perf board, what advice would you give to mitigate EMI and anything else problematic in using ptp in such a system?

Feel free to pick my brain - I'd be glad to help.
