Introducing the Jam Jar!

The Jam Jar

I’m working on a project right now that involves building digital synthesizers that react to light. As a first step I made a small synth that I was able to fit inside a jam jar. I creatively named it the Jam Jar, and it totally rocks. Here’s a video that explains what it is and shows me jamming out with Ableton Live!

[edit]> I neglected to mention that I built this synth with enormous help from a tutorial on hack-a-day!

Seems like an age-old APC with pots replaced by photo resistors, kinda like the Beep-It by Michael Una. Nice build anyway, but would have been cool if you didn’t act like you invented it.

Hey Simon,

You’re right, it is very similar to the Beep It, I hadn’t seen that! Thanks for the link. However, I’m not claiming to have invented this anymore than Michael Una is! I simply took a tutorial from Hack A Day and modified it slightly to make the Jam Jar:
I’m not interested in “inventing” anything, I just like to make fun interfaces for making noise.
