The great secreat of sustain pedals for electronic keyboards is that they are just on-off switches. That is, when you press the pedal, two wires are connected. That's it. Now suppose you are in the mood for composing and playing, and you realize that your pedal is somehow missing. This instructable shows how to make a temporary (but working!) MIDI pedal out of things around you. No tools, experience or ability required !
You will need:
1. An empty CD box
2. 3-5 Paperclips
3. Some wires
4. 1/4" jack/adapter with cable
5. Duck tape
6. Plasticine cat to oversee you activities
Step 1: Attach paper clips to make it bouncy
1. Take an empty CD box and remove the label.
2 .Put a bent paper clip inside, as shown.
3. Tape it to the box with duck tape.
Now if you try to close it, it will bounce back, like a pedal. The problem is that it will snap closed if you press hard enough. We resolve this problem in the next step.
