Fuse Killer 3000
AKA: Fire Starter 3000, Fuse Finder 3000
Instructions
Fire Starting:

- Turn on all switches to full power

Fuse Finding/Killing:
- Plug into circuit with fuse
- Turn on all switches to full power
- You just blew your load old son
Fun aside this is a legitimate tool used for load testing circuits. If a circuit is corroded or missing wire strands then it can still ohm out good, but not be able to carry the desired loads. This tool can be set to the desired load of a circuit to actually test it properly.
The popular Load It tester sells for ~$200, but this can be built for $40-75 depending on what you want for bulbs. My version also features a built in amp meter, easily changable probes, and more switching options giving more granularity in chosen loads. Parts list is below, and check out my video on it.
Most of the time building it was on layout and making the holes in the project box, so a 3d printed box would cut a substantial amount of time out of this. Another reason for me to get a 3d printer. If anyone would like to design a box for this, that would be sweeeeet!
