Nicolas Villar was presenting his tangible exploration on how to feed an interactive device with non battery power. To show that these human powered objetcs are nothing new, he shows an illustrive image of the zenith space commander tv remote control from 1955, a remote that releases a frequency using the power of turning the switch on. I really like the idea of creating the power one uses by him or herself, like a mobile phone that passively charges by carrying it around or speaking in it´s microphone. Nicolas (by the way oneof the organisers of last years TEI conference) and Steve use a more active way of creating power. By turning a DC motor like a knob, a dynamo effect is triggert and power is created: the faster you turn, the more power is created. In the Demo Session this afternoon they will a possibility for us to squeeze them out how everything works in detail. One of the questions that arise is if there is a chance to store energy, for example to not have to turn it on a special occasion. for gamecontrollers, this might be smart, like the wiimote should be create it´s own power by waving, boxing and swinging golf putters. On those tasks microcontrollers need a steady power supply. For now, check the paper and hold on for the interview.
