Building the Open Jam Box 0.1

Impressions of the process prototyping a 4-track loop station that is meant to be played collaboratively by up to four people.

Part of FabAcademy Challenge I. See here for repo and here for 3D files. All files CC.

Material used was 3mm clear acrylic, cut at 65% power, 0.3 speed and 22000 Hz frequency on a Trotec Speedy 100.

Software based on Raspi Looper by RandomVertebrate.

Early sketches of the case by Joaquin.

We used a paper prototype to get a feeling for the dimensions of the case.

Connecting the first track interface elements after installing the necessary libraries on the Raspberry Pi.

The acrylic sheets after the laser cutting.

The assembled case featured a mount for the speaker, as well as several holes for 1/4 inch audio plugs and the Pi power supply.

Finishing all four track interface elements (2 LEDs, 2 buttons each) on the breadboard.

Soldering all 30+ connections took a while, but it allowed to get more routined at soldering.

Integrating all the electronics in the acrylic case.

The (almost) finished loop station.
