usually that should not happen. but for example if you forget to solder Pico's GND wire, you get the APU smoke.
However my Lite's APU was alive even after 3 smoke fires.
Great answers everyone, much less concerned about sending out 'recalls' to my clients XD
I've been doing my MOSFET installs to only one cap because I figured the *APU itself has the caps connected underneath. Both single and double MOSFETs have worked for me this way at least twice (usual AMAZING glitch timing as well).
@Dee87 keeps suggesting that I change to a double-cap install and says that, @rehius specifically, recommends so. May I inquire to your thoughts on this?
Sorry I kind of bombarded you with questions @rehius, what do you think about single-cap-MOSFET installs though?
