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. ***
