Intro: Foot Activated Light Up Face
A Halloween face for a scarecrow that lights up when the foot switch is stepped upon.
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
20 count Variety Pack of LEDs
PC Board for Mounting LEDs
Flexible Insluated Copper Wire
Needle and Thread
3V coin cell battery
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
