The CRASH Space loves you LED heart light was originally developed as a Valentine's Day promotion at Cinefamily's Electric Dreams Pajama Party. It is now being used as a thank you gift for donations and general swag.
We are providing this file for other hackerspaces to use in the same way and for individuals to share the love.
This project is incredibly simple. Print it out, pop in the components, assemble the pieces.
The biggest potential mistakes are putting the heart on backwards or reversing the leads of the LED. To keep the LED leads in place I used a Rubber band made from a bicycle inner tube. We've also used conductive tape, regular tape and regular rubber bands
