An Audio Sampler Rube Goldberg Would Love

Posted by timothy on from the let's-test-ourmedia dept.

Thiago writes "Here is an audio sampler I made with 4 IR LEDs and 4 IR sensors. When something reflective goes by one of the sensor/LED combos, it triggers an event on the computer. On the videos, I mount the device on a turntable and use coins to trigger sound samples of my choice. I'd also like to make the project open-source (or whatever applies to hardware) but know nothing about licenses for this."

    One suggested improvement: have the reflectivity control some variable (like pitch). small/dark/further away reflector will give you a low note, and a large/bright/close one will give you a high note.

    I'd describe this as a sequencer, not a sampler.

    I bet you didn't already apply for a patent? then you just published it(making it unpatentable, even by you) and made the idea free for all to use.

    This device is simple. If you had a quarter dispensed by a complex pathway, say using wires, traps, egg timers, cats yowling after having their tails smashed, etc., THEN you would be approaching Rube Goldberg territory.
