Make your own Sustain Pedal

If you are a musician, chances are you must have already realized that some gadgets of the trade are exquisitely pricey, despite being very primitive in concept. The sustain pedal is not that expensive, but in its essence, it’s just an encased switch. So, why pay anything for something if you can pay nothing?

Besides, if you perform live, you know that most stages don’t provide adequate illumination to keep you from tripping over cables and stands during setup.

This flashlight/sustain pedal is an NC (normally closed), momentary (non-lock) action sustain pedal, suitable for use with keyboards, synthesizers, MIDI controllers, guitar amps, etc. Sustain pedals are very useful and if you have a bunch of synthesizers and keyboards and guitars, you will agree that one can’t have too many.

Moreover, these days, the “reduce, reuse, recycle” mantra is earbleedingly repeated, although not always accompanied by info on how to exactly act about it, so I hope this little project will satisfy the green-concerned musicians. And it provides that achievement feeling only a true DIY deed can.

 

 

What you need:

Tin can (candy and sardines are excellent, but any squishy involucrum will do)
P10 jack
9V battery clip
1 old flashlight with working LED (preferably crystal type)
1 300 ohm resistor
1 old mouse
1 9V battery
soldering iron, solder, insulating tape

 

Open the mouse and extract the tiny switches under the buttons. Some have three, others only two, but the good part is, no matter how old and battered your mouse is, probably at least one switch is working fine (since they are designed to withstand some millions of clicks). You can strip the cable and get the wire you’ll need to connect the components together.

Also, take out the LED from the old flashlight, taking care to not to cut the leads too short or melt it if you have to dessolder it. Remember, a LED is just a diode and, therefore, it’s heat-sensitive.

Simply drill holes to pass the jack and the LED tightly through. Find something to fill up the space inside the can, so when you step on it the switch is triggered. Here, I used an empty adhesive tape spool, cut to keep the switch in place.

The switch you took out of the mouse has three terminals: a NO (normally open) lead, a NC (normally closed) lead, and a common lead. Check carefully, they are identified with tiny text. But you can use a multimeter to figure out which is which.
