Holiday Season is coming. Christmas decorations are everywhere. One of the gadgets that can be found everywhere are led tea light candles that really flicker. They are cheap, clean and not as dangerous as real candles.
But how do they work?
I read somewhere that the flickering was obtained by a sound generating chip hidden inside. I tried and tried to find the original article back, but I did not succeed. So I went shopping and made this instructable. This is not my invention and all credits should go to the person who first couldn't control his curiousity, just like me...
Important: I am not responsable if your experiments go wrong and you ruin your equipment, your Christmas or both. So be careful...
Step 1: Gather Materials
What you'll need is:
1) battery operated led tea light (less than 1 euro)
2) either one of following items:
- (computer) speaker
- mp3 player headphones
- audio cable
3) optional: little pieces of metal wire or a soldering iron in order to make the connections
