solid state relay, photoresistor-led case
thingiverse
v2: printed it, cap is too fat for the case.. slimed it v1 : havent printed it yet. this is a poor man's relay kit! add in a photoresistor and a led, use the led as input and the photoresistor as a switch. this completly isolate two circuits like a relay would do, but its silent.. probably faster and way cheaper.
