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 :smile:
