Step 1: What You'll Need
Here's what you'll need to make 4 drums:
- 8x Piezo
- 4x CD
- Mouse pads (enough to cut 8 circles as big as the CD)
- Arduino + USB cable
- 4x 570k Ohm resistor
- PCB or breadboard
- some wire
Optional:
- 4x 3.5mm plug
- 4x 3.5mm socket
Step 2: Soldering Piezos
The first step is to solder long wires to the piezos.
My piezos came with a little metal cap and short wires. You can cut the metal cap of and simply solder longer wires to those short little wires.
If you chose to use plugs and sockets, you obviously have to solder your plug to the other side of your wire.
Step 3: Breadboard/PCB
herwise you might get false values because of noise.
You can either connect everything on a breadboard as shown in the diagram. Or you can solder everything on a piece of PCB like I did.
Now that everything is soldered, it's time to make the drum pads.
Take your CD and put it on the mouse pad. Draw a circle around the CD and then cut it out. Next stick the piezo to the CD with a piece of tape.Once that's done you'll need to glue the mousepads to the CD. I used a tiny bit of super glue. Make sure the glue doesn't get on the piezo! It'll ruin your piezo. I had to learn that the hard way.
Use a bit of glue on the edges of the CD and stick the plastic part of the mouse pad to it. Do the same for the other side. The foam sides of the mouse pad have to be on the outside.
Use some extra glue around the part where the wires stick out of the drum pad to close it nicely.
That's pretty much it. Everything has now been put together and the only step left is to connect everything with the computer.
There are a few possible ways to connect. After some research and trying different programs I found Ardrumo (Mac OS X only) the easiest to work with. Simply load the sketch to your Arduino and then open Ardrumo and Garageband.You can choose different drums in Ardumo as you can see in the video in the first step.
But like I said, this is not the only possible way to connect. There are a lot of other ways, for example using Hairless as explained in this Instructable. Just play around a bit and find a method that suits your needs :)
