arc lighter by Ken Killeen of Terran Sky

in #steemir • 8 years ago

A mini high voltage kit circuit, powered by a rechargeable 3.7v Lithium battery, boosted to 15kV using a small and very simple driver. Handy when a lighter is empty, wet or unavailable... providing a reliable ignition source.
Has small defensive attributes too ;)
