This is a tutorial on how to make a wand capable of the Lumos charm
from the Harry Potter universe for about $10. It is so bright you can use it as a flashlight!
The key to this design is a high power LED. I'm not talking about those little through-hole guys that you can use for underlighting your car... I'm talking about the 3 Watt LED's that they put in high powered flashlights! So this Halloween, I chose to put one of these buggers to good use. This project requires that you know how to solder.
Here's what you'll need:
- 1 3W LED - $4 at Digikey
(Anything with the same voltage rating will work)
- 1 stick or piece of doweling cut 10 to 14 inches long
- 1 Energizer Lithium Photo 123 Battery (3 volts, available at most drug stores)
- 1 small switch
- 2 yards of thin, insulated wire (I used thin speaker wire for this tutorial, but unobtrusive two-stranded wire works great too.)
- Soldering iron and solder
