Hey Guys,
after surfing the internet for finding a idea for my diy drumpad issue. I found an nice product.
Barepaint Conductive Pen (8,55€ /10ml) which can be used to paint your circuts (on clothes,pcb,…) or even glue parts instead of wiring.
There are a lot of interesting tutorials on their Homepage like Making a Touch Sensitive Circuit, Learn how to Paint a Capacitor! or Making a MIDI interface with the Touch Board.
Now i have a lot of ideas how to use it for my Boxes
