Article Summary
Educational electronics kits like the one from Minty Geek are a great introduction to the world of circuit building and electronic tinkering, but are perhaps a little too basic for more advanced hobbyists. Three MIT students are currently enjoying enormous success on the Kickstarter crowd-funding platform with a DIY Tesla coil kit called oneTesla that can make artificial lightning sing ... well, erm, play music from a MIDI source. Now where did I put that polyphonic version of This Town Ain't Big Enough For Both Of Us by Sparks?
