Rob sent in the latest gadget freak, he writes -
Seeing great potential in a normal, off-the-shelf product, Pete Griffiths designed a circuit he popped into the lamp to give it a new lease of life. His design combines a PIC and three constant current buck converters to create the RGB LED controller. This controller drives the high power 350mA LEDs using PWM to control the LED brightness. By driving the red, green and blue LEDs with varying pulse widths the controller can generate up to 16 million colours using fades, strobe and static effects. Who says you can’t give the humble lamp a nip and tuck? [via]
