The second project I managed to complete was a so-called “valve sensor” for the Camera Axe trigger I built three (!) years ago. This is connected to one of the sensor ports on the trigger, which can then open or close a solenoid-operated valve on the sensor, allowing water from a reservoir to flow through […]

Projects under lockdown I
