I came up with this question right after I wanted to take apart a microwave to see why it wasn’t heating anything before I remembered that that’s a very, VERY bad idea

    DO NOT backfeed your house’s electricity with a generator when your electricity gets shut down. You might electrocute someone working on those lines.

      At least have it set up downstream of the main shut off and make sure that main is off before firing up the generator. There are devices available commercially that do that for you but they aren’t cheap and require professional installation.

    I was actually going to say microwaves, but specifically the thing where people use the parts to make those things where you can burn fractals into wood. They look super cool but apparently if you brush up against the wrong component your heart just stops.

    Old arcade machines. Giant capacitors + little knowledge on the subject = a very bad time.

    As with anything it can be done safely if you know how. People still play those and they obviously need repairs/maintenance sometimes.

    I had a problem with the control panel in my Panasonic microwave and was able to fix it pretty easily. Everything I needed to get to was inside the right front of the microwave; the control pad membrane and the sticker that goes on the front of it.

    Holy shit, how has no one mentioned rechargable batteries?

    Lithium Ion batteries, commonly used in phones and the like, rapidly catches fire and emits acidic smoke that will melt your lungs when the battery is punctured.

      Of course I understand caution with ⚡️, but just about everything has a ‘do not open’ label on it (in the litigous US anyway). Do we not care about right to repair?

      Eh, I’m not sure about that broad. Macbooks say not to open them because “reasons”, but most items in there can be easily repaired

        Actually not. They CAN be repaired, but are a nightmare of soldered and glued shit. The only apple thing I own (Linux/Android/Win user) is an iPad, which admittedly is a sweet performer, and iPads are just plain better tablets, but no way I’m cracking it open. I’ve replaced Android screens, repaired laptops, but fuck apple. Not because of danger, but because breakage is almost guaranteed on newer stuff.

    I too was going to say microwave before reading the post body. Honestly though anything with a large capacitor, I can’t give you examples unfortunately because I study physics not electrical engineering but some of those fat fucking capacitors will fry you and they hold their charge.

    If you’re gonna take a washing machine apart and you cut all the wires, make sure you cut the main electrical plug off as well or your dumbass son (me) will plug it in and electrocute himself with it.
