Product #: MKLA1

The Color Night Joule Thief is a simple soldering project that lets you build a darkness activated color-changing light. The joule thief circuit only needs 0.6 volts to operate so a "nearly dead" battery will power it for quite a while. The circuit features adjustable darkness sensitivity and an RGB led that automatically cycles through a rainbow of colors. It's a terrific first soldering project.

 

Although the picture shows three, you only get one joule thief per kit.
  • Compact & streamlined design
  • Uses only one AA battery (or any 1.5V battery you can hook up to)
  • Easily adaptable to different size batteries - hook up holes to attach home made clips
  • A multicolor/color changing LED
  • Automatic turn on via a light sensor (adjustable sensitivity level)
  • Energy efficient - works even with a run-down battery, down to 0.6V
  • Makes a mood light
  • Perfect first soldering project!
