(for various reasons I needed to join a mismatched pair of 18v drill and battery, annoyed at how much fun it was)

    I made Franken - Bluetooth speakers. Works better than I thought. One 3rd party ryobi battery is enough for a festival week. The second Bosh lawnmower battery adaptor works fine too.

      A couple years ago I got an electric lawnmower super cheap. I only discovered earlier this summer the lawnmower and accompanying weed whacker were being discontinued, and if they break in ways I can’t fix, I’ll have a 60v, 5 amp battery to recycle play with.
      It hasn’t occurred to me to reuse the battery for some other fun project. There will be shenanigans.

      Oh my, you’re who I want to talk to. I have been thinking about making a speaker probably for the opposite reason you did. I want it to be quiet. Quiet as a little mouse. Do you mind guiding me towards your method? Because I am just at the beginnings, but I was wondering if the hardware does the work, or if you get the fixings and then load the hardware up with something open-source. So if you’ve got the time, please let me know!

      Also GJ on the frankenspeaker!

        I still had a Tda7492p board laying around. That’s a stereo Bluetooth 4.0 board with 2x50W (8-25V).
