I made the mylar stencils used to paint conductive paint on my son’s wall with my Glowforge. My wife used the stencils to paint the wall, and connect it to a Bare Conductive TouchBoard which she made play Star Wars sounds whenever the various characters or objects are touched.
I have a video somewhere that might help in case it doesn’t make sense. Let me know if you’re interested and I’ll find a place to post and share it.
