is there a stand alone motion sensor like the D-Beam?

it takes all of us

i was looking for a package with MIDI output

all of the D-Beam instances are in rather large packages
just wondering if there was something developed but smaller

it takes all of us

Buchla Lightning senses the motion of its input sources.

The web site only shows the wands as inputs, but there are other types of input source, including rings.

Yes, there are quite a few motion sensors which do that, including theramin-to-MIDI (30cm range) (doepfer electronics, for example), video-tracking (range of several meters) (CMUcam, etc.), acoustic rangefinders (devantech, etc.) and light (up to 3 meters) (or infrared) sensors. A couple of years ago, I needed a large number of motions sensors for almost no money, so I used LDR’s to pick up the reflections of peoples clothes and bodies. I was using a 32-input CV-to-MIDI interface, but you could just as well wire an LDR directly to a game-port or a hacked Joystick. The end result was effective from 0 to 3 meters (depending on ambient light, clothing and skin-color) and looked like the photos on this page:

You could do the same thing with infrared without the need for the visual light I was using, as long as you have a good infrared emitter.

Have Fun!
