Re: Youtube guy does a tour of Crochambeau's studio.
Last year after dropping my folks off at thr Burbank Airport decided to check out Apex Surplus which is one if my favorite places on Earth.i had heard they were on the brink of closure during the isndrmic but somehow they made it through and had actually organized the place. I bought a bunch of shit...

Re: Auto-shutoff methods in consumer-grade circuitry
This lead to us speculating that the main IC blob is using the crystal as a source for the timer (makes sense: crystals are super accurate) and that replacing the crystal with a different one might expand or shorten the time limit. Well not even with another crystal but with an osc.. https://circui...

Re: Auto-shutoff methods in consumer-grade circuitry
If you turn the unit on by pressing the button, and then casually press the button again at say, 1 minute 55 seconds, does the unit turn off in another 5 seconds or does it remain powered for another two minutes? Not holding the button state, but enough of a change state to retrigger the timing sec...

Re: Auto-shutoff methods in consumer-grade circuitry
It bears reiterating: in order for this to work, the crystal must be connected before the VOICE [CHANGER] button leads are connected. That's two separate button actions just to get this stupid star wars toy to stay on. :hissyfit: Crazy.. so the blob is using the crystal for the timing source.. so y...

Re: Auto-shutoff methods in consumer-grade circuitry
Ah.. well since this is a matter of just retriggering after the timer runs out then I'd use a fast pulse signal out of the 555 into one side of the switch.. hopefully this will not cause as much of a pop

Re: Auto-shutoff methods in consumer-grade circuitry
Does pressing the voice changer button reset the "timer" or is it just a matter of repressing it frequently enough that it closes the circuit again shortly after it opens? Short answer: the former. Long answer: pressing the voice changer button ("VOICE [CHANGER]" in my photos) i...
