Using vactrols for circuit bends

Here’s a short video on using a light sensor with an electron toy, like a speak-n-spell for circuit bending, as it’s exposed to different types of light it create different distortions – Link.

    Ah, Forrest Mims would love to see 21st century kids using 555 timer ICs from Radio Shack.

    Mims is still alive and kicking, he was featured in the book “Makers” by make magazine. Cool circuit.

    So I got the RS Optical Theremin working, but for some reason my volume phototransistor burns out or something after a day. It still reacts to the light on the pitch phototransistor, but it is not as loud as it is the first day a built it because of that cell. I built two and this happened both times.

    Any thoughts as to why this may be happening?

    it’s like showing a picture of a house with a caption that says this is how you build a house……in other words USELESS.
