Step 4: Make The Insulating Spacers
The Three conductive sheets are held apart by insulating spacers. Pushing between the spacers creates a conductive path. The insulating spacers are the white dots that are made by screeding Oogoo in the holes in the stencils. The stencils are made by drilling 1/4" holes in 1/16" plastic sheet. The holes are drilled 1" apart with the holes in the second stencil drilled in between the holes in the first.
Screed the Spacers
Step 4 pic shows a small mix of Oogoo (2 silicone caulk to 1 corn starch by volume) being screeded on one layer of Oogoo II.
