I had a really great time making a video on how to build a copper tape and conductive paint touch-plate for my eurorack system. I start by making the paper mache octopus and then detail the wiring and soldering of the circuit, which uses a 9 volt battery as a voltage source. I am happy to answer any questions about it, and I hope you think its as cool as I do. Would love a like if you find it interesting. [Patch Notes in video description]
