Smoke stopper / switch for creating FVP drones
thingiverse
Working from home means lots of extra time, so I designed this smoke stopper to be safe while building FPV drones. Use one switch for the bulb as a smoke stopper or use the other one just for a switched bypass - the wiring diagram is on top and also printed. The red LED indicates that one of the switches is turned on, therefore I used a small DC-DC Converter (LM2596 or LM2596S) to convert 13V-16V down to 3V. But you don't necessarily need it, so I'm providing two lids - one with an LED whole and one without. The bulb is a bilux 21W/5W 12V one, combined into one line, making it about 26W, which should be okay not melting at first try. The switch ... just take one of these. Enjoy!
