Build An Optical Theremin
The Theremin That Uses LightAn Instructables by Sacred
What is a theremin? It is an instrument that can be played without being touched. Traditional theremins use antennas and oscillators to sense a person's hand and generate a tone. Ours will use light instead. Because of this, it is not an actual theremin, it just uses similar principles. As a side note, this is my first instructable, so please be nice.
Step 1: Gather MaterialsThis needs very few parts, I made mine for under $20.
Here is what you need:
|Part Description||Manufacturer Part Number|
|TLC555 Timer IC||TLC555CP|
|Battery Pack (to fit 4 AA)||SBH-341-1AS-R|
|AA Batteries||ALK AA (EN91)|
Make sure you get the right thing!
I recommend getting a socket for your chip.
Very convenient. Above is a breadboard.
Step 2: Putting it TogetherThis is a really easy circuit to build. Just make sure you follow the directions, and yes, the image came from Instructables.com.
Step 3: The Finished Product and VideoAt this point in the game, everything should be working. Congratulations on the build, have fun with it!
