Video Walkthrough
Another excellent video by Steve Hobley, this time testing out the Light Theremin. Once you've gathered all of your parts, this project can be built in next-to-no time. Simply follow the placement of your components with our step-by-step photos. And remember, if you come up with other ways to hack, modify, or extend the abilities of your Light Theremin, we'd love to hear about it. Send us an email with your mod. (You might even win something!)
Photodiodes or Photoresistors?
How about both!? That's the beauty of the solderless breadboard: you can swap out components on the fly without the need to fire up the solder iron. Photodiodes (left) convert light into voltage; the resistance of photoresistors (right) decreases with increased light intensity. Experiment with both to understand how each component operates, and also how they each produce a different voltage, and therefore different "noise" from your theremin. You're actually hearing electricity.
Weekend Projects Success!
MAKE reader Brian writes from Baltimore-Washington International airport in Maryland: "Got the Aircraft Band Receiver working this weekend! Managed to pick up Washington Center at 134.5 MHz. Picture is of me near the BWI tower. Great fun and it now has me thinking about other RF projects!" That's wonderful, Brian, and thanks for sharing your story. For his successful hack, Brian will receive a FREE Maker's Notebook, courtesy of Maker Shed.
The Weekend Projects Challenge
Oh so you too want to win a Maker's Notebook? The rules are simple: complete one of our Weekend Projects and send us an email with a picture of your finished build and a story about your experience.
