I always powered my axoloti with usb. However I'd really like to power from 9V.
I have 2x cv.ocd that are powered from a 9V guitar-power adapter-thingie. On the cv.ocd it says "9-12V center neg", and the graphics on the axoloti suggests it's the exact opposite, so I bought a small inverter cable in a guitar store. My meter tells me that the power should be correctly inverted and I assume fit for the axoloti.
I'd really appreciate it if someone here could look through the images and verify that it's safe to proceed, plugging the 9V into the axoloti....
