  • I need to do a video on this, but I actually just got around to trying some different things with Piezos and the results are a bit disappointing.

    However it seems that if you don't care about the heart rate sensor, you could poke out the little circle in the middle and glue the piezo over that, and it might actually be ok.

    Soldering shouldn't be too bad as the pads are quite far away from other components, but you'll still need a proper soldering iron (not a gas powered one, or a massive one you use for stained glass :)
