The Tesla Gun is a hand-held, battery powered lightning machine. It is a spark gap Tesla coil powered by an 18V drill battery. You pull the trigger, and lightning comes out the front.
It is functionally inferior to that of Tesla’s design in the Five Fists in a few important respects. Notably, it is a bit longer and heavier than Tesla’s own. It also cannot (yet) create an ion wind strong enough to cushion the user when leaping from a four story building.
On the other hand, my design is an improvement in two important respects: 1) It is battery powered, and 2) It actually exists.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
