Picture of Blowable LED candle
What would you do when you suddenly remember the birthday of your friend, but you got no candle at home or office...
Well, that was the reason why I made this so that your friend can still make her/his wish on the spacial day.
The project is the result of improvisation, made of everything I could find in my office desk in 30 min. (I have a bit of strange selection on my desk.. but do not ask..) The principle is very simple. The connection between battery and LED is going through the tilt switch, which is placed vertically on the blow target paper. As you blow the target, it gets tipped over and the tilt switch lays horizontal, resulting to disconnect the connection between LED and the battery.



Step 1: What you need

Here is what you need (or what I've used)

-1 LED
-1 button battery (3V)
-1 tilt switch
-some conductive thread (can be wire)
-paper
-tape

tool:
-scissors
-pen

You can buy conductive thread at hobby stores and http://www.sparkfun.com/commerce/product_info.php?products_id=8549 and a tilt switch can be found at radioshack sometimes.
