I want to teach a class on repurposing electronics. We could start out just taking some broken things apart and seeing if we can fix them, but every student would have to pick something to repurpose or revive as a semester-long project. Maybe they want to turn an old propane lantern into an LED lantern, convert a cordless drill with dead nicad batteries to lithium, or jailbreak an e-bike. Everyone should leave the class with a device or appliance with a new lease on life. A community college should hire me for this
@MLE_online you know I'm giggling cause of the thing about not being able to find e-waste parts for the speed circuit :]

@RueNahcMohr rue, you need to understand that there's a difference between something being technically possible and something being feasible.

The only municipal e-waste dropoff site around here is only open from like 9-4 Monday through Thursday, and it's about ten miles from my house.

I'm not going to go all the way over there to see if they have junk that I can bring home, open up, and look for optoisolators inside, then take all the way back to the e-waste dropoff site to get rid of -- just so i can try an experimental circuit you showed me on the internet.

@MLE_online I know, and I sort of wish I could prove it (tho it doesn't matter) but I'm sure on your bike trips you have encountered multiple e-waste things that would have almost everything you need in them.

It may not seem like it, but I do understand your position.

@RueNahcMohr ok, and when i'm on my bike, how am I supposed to bring home these appliances? I would have to go back with my car

@MLE_online I dont know which bike is your daily driver, dont have you a thing that would fit a dvd player on it?

wait, I feel like I'm pushing now, is this just postulation?
