Now here’s an LED mood lamp that you can make yourself. Parts needed include 3 NPN transistors capable of driving 500 mA, a small perforated circuit board, one z-power 3 watt rgb led, and a IKEA Mylonit lamp. Full instructions here. Short video demo after the jump.
After making my pyramid mood light with 12 high power leds, i decided to make a bigger and better version, without the emphasis on the low budget. The colors also mix better because of the wider opening angle and because the rgb chips lay very close together
