Universal High-Power LED Driver
For the last 4 months, I’ve been working on “practical” side of things, and finally released this.
It’s a “universal” LED driver that supply constant current to high power (1 – 3W) LEDs. With remote controllable dimming and up to 3A of peak output current makes this a “one size fits all” kind of driver for many of your LED lighting projects.

USB Power Cord
Here’s a little addition that makes Auroras more desktop friendly. You can use this cord to power Aurora 9×18 mk2, Aurora 18×18, Aurora mini 18 or Aurora 9 bar and other kits from any USB ports. A standard USB plug on one end, and Molex 2 pin connector on the other end. About 24 inch long.

Aurora mini 18
Aurora mini 18 is only 2 inches in diameter, yet controls 18 full-color (RGB) LEDs individually. The technology that enables this little thing is as amazing as the lights it produces.
Please review the instructables before purchase – assembly requires soldering skill. You will also need PIC programmer such as PICKit 3, ICD 2, ICD 3 (PICKit 2 doesn’t work with the PIC used). If you don’t have a programmer, you can purchase the PIC programmed with the latest firmware. (The PIC will be soldered to the PCB)

Night Joule Thief – LED Night Light Kit
Joule Thief circuit is combined with an ambient light sensor – Night Joule Thief is a little night light that keeps going with just one battery for weeks! Two white LEDs light up surprisingly bright.
* This is the original version of Night Joule Thief that uses white LEDs – not to be confused with the new color changing version.
Please view the instructables for technical info and assembly steps.
*** NOTE: The color of the PCB will be green instead of purple shown in some of the pictures. ***

“Joule Thief” LED Night Light
“Joule Thief” circuit is an inductor based voltage booster circuit to light LEDs with low supply voltage. The circuit was published in 1999 and has been quite popular. You can see the principle of the circuit here: http://en.wikipedia.org/wiki/Joule_thief
My version is a variation that uses single coil inductor, to make the inductor easily obtainable. I design the circuit using readily available parts only, to make it an ideal DIY project.
