DOUBLE KEYBOARD

Step 4 TWIST AND TAPE

Twist together groups of three wires consisting of the same color. Tightly wrap them in tape so that none of the copper is showing.

NOTE:''
Yes, I know taping the connections is totally ghetto. I have since bought a soldering iron, but I will also say that this taped version has been working for over a year and half, and has survived several moves. LONG LIVE SOLDER FREE DIY!
