Wensleydale bare bones micro SEC tower

This is a quick vid of a small 5″ or so wireless electricity tower built today. The components are just a C3198 NPN transistor and a green ‘power gauge’ LED, to set the 3 wind coil correctly. Power is from an ex laptop battery cell, about 2V it seems. The wireless field is being measured by a circuit from a keychain laser pointer, which has a bridge rectifier and coil connected instead of battery connections. With higher voltages the laser runs 🙂
