the gatemachine
2024
The gatemachine is for controlling 8 inductive loads like solenoids directly with control voltage gates. The robust and fully analog circuit operates between 12 and 24V and features hysteresis and an adjustable threshold. The connectors were selected to match the existing hardware.
It was commissioned for controlling an 8 channel valve block in an electromechanical acoustic installation.

MSG24
2022 – 24
A module for controlling 24 solenoids via MIDI, operating at 12 – 32V.
Using a common microcontroller board and common glass fuses to ensure easy repair in the field.
Several revisions as reaction to volatile component supply.
