Multi-Touch Interface on the cheap(really cheap)

Step 3 The LED Pen device

The following pictures(sorry about the quality) are my newest version of the LED pen device, in the picture i have about 6-7 LED's attached but you only need 1 or 2 for extra precision

Materials needed are
3 volt small clock/watch battery x 1
Zip tie x 2
Electrical Tape
Switch with 2 wires coming out of it
LED's x 1/2 (your choice)
Penny x1

Steps for it are:
1) take the + side and face it down
2) put a wire to the switch on the - side
3) wrap zip tie tightly around battery so wire is held firmly, cut off excess zip tie
4) put tape on battery and zip tie
5) place penney on tape making shure it does NOT touch the battery
6 place second wire to switch on penny
7) tightly tie second zip tie in opposite direction than first one and cut off excess
8) place squares of tape on top/bottom
9) insert LED(s) by taking the long end and bending it up a little and then further down bending it down so the two wires a further apart but still even and parallel with each other


and make shure the - side touches the penny and the + touches the + side of the battery and when you flip the switch it should turn on, this is a very easy/compact way of doing an LED pointer for this project
