Here we’ll show you how to make a light theremin that has a
Here's a video of the theremin
1x Wazzabi Punk PCB
1x Red LED
2x 555 Timer IC
1x On/off Switch
1x 9v Battery
1x 9v Battery Snap
8x Short cables
6x Long cables
1x DVD case
3x Strong magnets (recycled from garbage, don’t know what they were for)
1x 330 ohm
1x 1 kohm
1x two axis joystick potentiometer (recycled from a broken USB Gamepad)
1x A50K Potentiometer
At the bottom you will find the Fritzing file with the schematics and PCB of the circuit we used.
Step 1: Making the PCB
Since this task excedes our instructable, feel free to follow these instructables instead:
- How to make the PCB board (available in Spanish)
- PCB making guide
We suggest you mark where every component goes with a sharpie marker on the rear side of the PCB.
Step 2: Prepare the two-axis potentiometer from the controller
Since we'll be soldering our cables to the PCB, we just need to cut around the potentiometer in any way we find appropriate.
Step 3: Soldering the components
We soldered them in the following order:
4. 555 Timer ICs
6. A50K Potentiometer
9. 2 Axis potentiometer
10. Battery connector
The crossed cables may be a little confusing but look at the PCB image we took from Fritzing to figure out where each cable goes.
