| The Pedal Powered TV/VCR Designed and Built by Bart Orlando | ||
| The pedal powered tv/vcr was designed and built by Bart Orlando for display at CCAT's pedal powered lab in 1998. The components include a Schwinn recumbant exercise bike, a 1800 rpm - 24v permanent magnet generator and a Panasonic 12v-color tv with a 13" screen. The generator is driven by a fan belt which wraps around the outer circumfurance or the bike's 15"diameter - 40lb flywheel and the 4" diameter pulley on the drive shaft of the generator. The generator is mounted on the underside of a wooden pedistle that the front end of the bike rests upon. The relative sizes of the flywheel and pulley determine the range of voltage the generator can deliver, which is between 0 - 20 volts. The exact output voltage is determined by how fast one pedals. The optimum voltage, based on ease of pedaling effort seems to be approimately 15 volts while pedaling at 90 rpm. There is no battery used in this system. Electricity flows directly from the generator to the panasonic tv/vcr, which has been operated this way for five years without damage to its circuitry. | ||
