This is USB-powered box for controlling up to 4 model servos by CV. I was asked for this by a friend who wanted to control some movements from a synth CVs using servos. From the left: button + LED, four CV inputs, four servo outputs (signal, +, -), USB input (for power only, no control […]

  S-230 Shuffled grid module for Eurorack / Doepfer A100 system. From the top down left column: clock input + LED reset input + LED setting button + 2 LEDs (short press sets trigger memory, long press sets trigger length) retrig button + LED swing knob + CV input jack output jack + LED right […]

S-411 Shaper module for eurorack / Doepfer A100 system. Compares input voltage (or ctrl input voltage, normalled to input if ctrl jack is not plugged-in) with adjustable thresholds (positive and negative). While input signal (or ctrl input) exceeds positive (or is below than negative) threshold then output is switched to DC level set by level […]
