[Noisebridge-discuss] conductive paint and inks

[Sean Cusack]

Ms. Rachel!

I have actually tried to pattern bare conductive ink before to make
capacitve sensors on acrylic. I did not silkscreen though since the ink is
stupidly expensive and I didn't want to give up so much ink to the screen.
Instead, I used a vinyl cutout, and painted by hand in the gaps like a
mask, then peeled away the vinyl at the end.

I'm not sure if the bare conductive stuff will work for you though since it
is water soluble. I put mine under a layer of clear coat to protect it.

Hope that helps! Good luck!!
