CIRCLE WITH A DOT

@ai6yr @MLE_online Yeah, the enable is required to keep the circuit from triggering as long as solar input is present, if I am understanding the circuit correctly.

@ai6yr @MLE_online I was just doing the same thing here, I would swear I've got some around here I could part with.

@MLE_online I mean, it's not going to be an exact science, but resistors, caps, and whatnot come in assortments so that's an easy setup. Cruft extra parts and donations tend to accumulate so that also helps, and sometimes you need to just do a mouser order and group brainstorm stuff that people said "wow, I wish we'd had a $foo sitting around, could have used one the other day to fix a thing" and stock up. Then curate every so often.

I have a pile of stuff personally that's accumulated over the years, so it's hard for me to judge, but any time I order parts, I usually get a couple of extra if it's not too much, ICs don't tend to take up a lot of room.

(The 74AC240 isn't an uncommon logic chip, or at least it didn't used to be)

@MLE_online Yeah, it's why my home hackerspace has a whole wall of honor-system components for exactly this reason. Can't get a lot of things quickly otherwise.

Had never heard of the pummer circuit before, looks like fun to have around.

@ethanschoonover Ah, the Cronenburg Question!
