Step Switch This link shows the basic idea for the step switch that I used. I did not solder anything for this project, as I wanted it to be a project with which small children could help.
All the components were either lying around the house, or were picked up from RadioShack.

Step 1: Materials

Tools:
Small sidecutters
Scissors

Materials:
Assorted Connectors
20 count Variety Pack of LEDs
PC Board for Mounting LEDs
Electrical Tape
Speaker Wire
Flexible Insluated Copper Wire
Needle and Thread
Fabric
Pillow Stuffing
Aluminum foil
3V coin cell battery
Paper

Step 2: Whatever Works

My basic method for making the circuitry on this one was to just take the groups of LEDs, twist all the + wires together and then twist all the - wires together and then clamp on an 'assorted connector'. then run wires from all the + sides of the LEDs to the + terminal of the battery. Nothing fancy, just making sure that the + side of each LED was somehow linked to the + terminal of the battery. The same was done for the - half.

Once the circuits were done, holes were cut in the fabric to fit them through and the boards were stitched to the fabric.

Step 3: Stuff and Stitch

I cut open an old pillow and put stuffing in and around the circuits and make it headlike. Once it was fairly stuffed, I laid a piece of cloth on the back and stitched around the circumference, leaving two wires sticking out of the bottom.

Step 4: Attach Battery and Foot Switch

I made a foot switch with layered paper and aluminum foil and attached it to the head with speaker cable. The foot switch is described on instructables as part of the Ghoul Grabber

thanx for quoting my instructable! I didn't solder anything either, but that was out of lazyness ;)

I think you're getting breadboards confused with PC board, which is what you used.

YES! Thank you for relaying the correct information.

you need resistors!!!!!

If you're running from button-cel batteries, the internal resistance of the battery prevents it from discharging more than the LED can survive. If you're using almost any other power source, gamer is correct - you need a current-limiting supply, or a series resistor to ensure you don't cook the LED's. read: Ohm's Law. Great instructable otherwise!

Perhaps I should've added a disclaimer that this only needs to work for about two hours, and not even constantly for those two hours.
