So I've got a fun thing that my roommate got at an e-waste place, and I'm gonna open it up and see how it works and if I can interface with it.
It's... a crosswalk button/speaker!
@foone That's one hell of an over-engineered push button
@Kuraio yeah. I suspect it's a combination of trying to make it super-sturdy and just plugging together existing cheap modules.
Like they probably already had a PIC chip that could stream audio off a flash chip to an amplifier, but instead of making the same chip also do the communications with the controller, they just stuck a second PIC in there
@foone Even that speaker looks kinda hifi-ish. I bet it could blast out some incredible bass
