I was thinking of doing a 'reset' button mod to my C~Mos
, the recessed push kind, but they're only two pin that I can find...
PS, heard a tip the other day about putting a spring inside tube and plonking it in a pan of boiling water for a while, then hold it to desired shape and stick it in a sink of cool water
...
Don't know where you'd find a suitable spring to hold the tubes shape open though...
