Maker Faire Bay Area 2009
Jack SparX Electrical Toys

Location: Redwood 408

Let me reach out and touch you with half a million volts! We'll share a shocking but safe experience. My Van de Graaff generator will make your hair stand on end. We can play with Tesla coils, light bulbs with no wires, see arcs and sparks as the air is turned to purple plasma! High voltage is fun to play with, and that's just what we do, but very safely. We have approachable Tesla coils, Jacob's ladders and some of the components it takes to build your own. This is our fourth year of bringing high voltage toys for us to enjoy at the 2009 San Mateo Maker Faire.
