These used to be available back in 2011. You can see some featured in the archives here. See the Mr.AcidMachine label some of their other products. The last post from them, prior to this one, was back in 2013.

From the listing: "This thing is rare! This is the only one for sale that I know of.Oscillating drum synth that can be triggered by the built-in pad, CV input, or audio input. It has an onboard looper and optical theremin. It is way too much fun.

It can be played by hand or set into 'loop' mode for drones, but also has CV and gate inputs for external control via analogue sequencers etc.

Runs on standard 9v power (same as most guitar pedals). I don't have an adapter for it as I always use my power brick. Or you could use a standard 9v battery"
