I put together something a bit more sonically interesting than the video that I posted earlier. I recorded myself improvising on double bass, and then processed the recording with a puredata patch that I wrote to use the 3 sensors that I have built so far. It’s pretty bass-heavy, and not EQ’ed or anything, so it probably won’t sound good on speakers without good bass response. All of the processing was done in one pass, and the only interface between myself and the computer was the 3 sensors. So if I had the sensors mounted on the bass, I could theoretically have performed this live with no pre-recording. The patch requires my granulator external, which is downloadable on my PureData page.

Here’s a quick video I made of me waving my hands around the MouseTrap sensors, and sending the data through an arduino board into my laptop running puredata. The video footage was pretty out of sync with the audio, which is why there’s more screen capture than video. All that the patch is doing is modulating the amplitude of 3 oscillators running at 400, 500, and 600 Hz. Soon I’m going to set up some sort of media gallery so that there’s a more permanent home for things like this, but this is it for now.

first three moustrap sensors plugged into an arduino
I’ve got 3 of the MouseTrap distance sensors built, and I have just a little bit more tweaking before the the design will be ready. The blue board that you see the sensors connected to is an Arduino, which converts the analog signals to digital numbers and sends them to my computer over USB

initial board design cut on a CNC machine
Today I milled out Revision 3 of my MouseTrap board, after realizing some mistakes in Rev. 2. After stuffing the board I’m happy to announce that it seems to be working great! I had to change some component values because the PCB acts differently than the breadboard, but performance seems good. One of the pads ended up being connected to an adjacent trace, but I moved it over a bit in the newest board layout, so we should be ready to go.
