Simulating 3-phase AC for energy monitor testing

Thursday, October 12th, 2017

Tisham Dhar blogged about his 3-phase synthesizer: Finding 3-phase is difficult, convincing the owner of the said supply to test some home made hardware is even more so. After building a 3-phase energy monitor my testing options for it appeared very limited. So I set about making my own low-cost 3-phase...

Teensy MIDI USB foot controller for controlling Mobius Looper

Thursday, August 21st, 2014

Thrifleganger wrote this instructable detailing his Teensy MIDI USB foot controller for controlling Mobius Looper: The concept is quite simple and straightforward. You press a button, the arduino interprets the signal arriving from the button as a midi "control change" signal (typically represented as MIDI CC), and this signal can be mapped...
