Max shows you how to make a music syncing light up orb clock, he writes –
“Okay, we have seen some really cool Light Orbs while trying to make this Music Syncing Light Orb Alarm Clock. We started with Tod’s creation and soon realize that 1 LED will not be bright enough in slightest light conditions though his Light Orb is tight let us say. So we checked out RGB lights at Hackedgadgets.com. Which is cool and uses 4 Red, 3 Green, and 3 Blue LEDs.
Well during our google search for Light Orb HOWTOs, we came to the Ambient Devices schematic and their technical notes. Well it says that with the right voltage, you don’t need to use resistors.
During our breadboard testing, this proved to be costly. We went through about 20 nice High output LEDs trying to match the forward voltage of LEDs… “ – Link.
