- Any static dissipative foam (If you’ve ever ordered any IC chips, you probably have some lying around. IC’s are often set in this foam for shipping.) or if you don’t have any, you can pick it up from a variety of places, such as this
- (optional) Plasti Dip Rubber Coating
Step 1: Step 1
Cut the foam to the size you like. You can cut it quite small and still get a good range of resistance levels. The foam in this picture is cut to less than half an inch square and about 1/4 inch thick; once completed these two each produce a range of around 2.6K Ohms down to 400 Ohms when squished completely.
Step 2: Step 2
Step 2:Poke two wires into the foam. Make sure the wires aren’t touching and there is a bit of a gap between the two so that when squished they won’t touch. To make sure the wires don’t come out while in use, I poked the wire all the way through and bent them at the ends.
