Solenoid valve SG90 servo conversion

thingiverse

Convert the low-cost, widely available solenoid valve to servo-actuation so your Arduino plant waterer doesn't need its own power generator. Requires: SG90 servo 10mm disc magnet One of those inexpensive polypropylene solenoid valves that are readily available Carefully snap off the solenoid part and then assemble this together, finally attaching it on top. Update: Now controls 2 valves. Files with "double" in the name for that setup. The main block features built-in breakaway support. Split and remove that if you prefer a different design. There's some flexibility to get the servo aligned perfectly, so don't push it all the way in and screw it down tight right away.
