nuetron 64 Posted December 3, 2011 Share Posted December 3, 2011 Most of the info is in the link: http://www.falstad.com/circuit/#%24+1+5 ... -5+4+-1%0A It works in the simulator, but will it work in practice? I've had NE555 timers operate down to 2.5v before. :think: In several simulations without the zener-regulator, the output voltage went up to ~85volts in under 0.5 seconds. I know THAT won't hold up in reality, the 555 would fry long before then... :problem: Just an idea that spawned and wandered through my brain today. What do you guys think?
