Some quick drone, the process of which is marginally more interesting: these were output from a pd patch running on a raspberry pi, into the maple box, and taken from the piezos out into my interface. The important part for me is that the whole thing -- Pi, Pi's interface hat, 20W amp, and homemade input buffer -- ran on a battery that only puts out 5V at 2A, even while I was SSH'd to the Pi.

Now to figure out those weird clicks...


Can't reproduce the clicks after a brief attempt.

Tons of line noise though, I'm assuming it's partly because I'm using the relatively dirty 5V from the Pi's GPIO. The noise increases when the SSH session to the Pi is busier (eg, with X-forwarding) -- not sure if that's RF interference or increased power draw to the Pi. Anyway, the goal is to run headless so those spikes basically don't matter, though I wouldn't mind cleaning up the overall noise floor.
