Good use for Old Microwave Ovens

at 1:28 am. Filed under Crazy Hacks


Microwave ovens are often discarded because they are old and don’t match the look of your other kitchen appliances anymore. Have no fear, there is a good use for these ovens. You can use the MOT (Microwave Oven Transformer) found inside for some high voltage fun or simply make a pressure vessel bomb out of it.  on Youtube has been having fun with these for years. Have a look at the above and below videos for an example of some of the antics he is up to. Make sure you subscribe to his channel if you like teardowns and some crazy high voltage fun.

    Those microwave oven transformers are also useful for DIY spot welders which is perhaps the most common use of them. The only thing is: I would not disassemble the microwave the way Tesla500 did. Sure, it’s quick 🙂 but I would hate to have to pull glass shards from every piece of hardware I could have potentially used later. Instead of destroying it like this, I would have taken it apart and saved the pieces.
    There’s A TON of useful stuff in there:

    * the transformer
    * VFD or LED 7-seg display
    * 120V shaded pole motor + fan blades for it
    * 120V smaller geared motor (from the turntable)
    * 120V light bulb and a nice compact socket
    * blow fuse + holder
    * high amp power cord
    * various high amp wiring harnesses with properly crimped connectors, nice lengths, too
    * a couple of hi V caps
    * tactile keyboard (just disregard the “chicken” and “popcorn” buttons 🙂 )

    and that’s just the parts that come to mind immediately, there’s a lot more I can’t think of at the moment. It’s been years since I was able to pass by a microwave oven set aside with trash without a twitch to pick it up, and when I’m not too embarrassed, I sometimes do stop and pick it up.

    Never throw away a microwave oven in any working condition!!!

    In parts of rural NSW, old microwave cabinets are used as rural letter boxes. They are bolted to posts and the mail deliverers open them using the open door button, insert letters or parcels then close the door for a waterproof delivery.

    LOL, that is a great use that I have never seen before Richard!

    I like the wires for sure.
    The transformer for obvious reasons.
    Never did find anything particularly useful to do with the other hv parts.
    One thing that i would mention is the fact that a microwave is a faraday cage (sort of.. not having that argument again)
    sometimes obvious things get overlooked, thats a pretty nice piece of tempered glass on the door

    one last thing, the over range and industrial models can be quite pricey. I grabbed a pretty fancy over range model by a dumpster. A roll of paper towels/some windex and a door switch (pulled from another trashed oven) later and I scored an easy 200 bucks. hell im sure i could have just spliced in a piece of wire and still sold it
