With the drastic rise in LED efficiency everyone wants to use them in their electronics projects, but in my experience most people are confused about how to properly power them. This kit should answer all of your questions about using LED's, and makes a good intro-to-soldering project.
This circuit was designed for use in model rockets, although it also makes a great general purpose LED circuit or flashlight (great for camping!). The circuit board links between the shock cord from the rocket and the parachute lines as shown. When the rocket ejects the parachute the high-brightness LED on the Chutelight points up into the parachute and makes it glow a brilliant red!
Included are all necessary parts (shown below) including clear heat shrink to cover the assembled circuit, and a lithium coin cell (swivel links shown to right are not included). The color instructions detail kit assembly and include discussion and equations on how to safely power LED's: choosing a power source, calculating current limiting resistor values, and powering multiple LED's from one source. Explanation assumes a basic understanding of Ohm's law. Requires a soldering iron, a heat gun (or other heat source for heat shrink tubing), and a rocket fuselage measuring over 1" in diameter.
