I made this little Eurorack for desktop experiments with new module designs.
- Sturdy plywood design.
- The righthand side (module with white panel) can be removed for access to module under test.
- The top can also be removed for access, but mainly when changing modules.
- The side module contains small power supplies for +/-12V and +5V.
- In the back of the cabinet I have:
- Small power-bus for 4 flat-cables.
- 2W class-D amplifier with jack-input and volume control.
- 40 mm loudspeaker.
- 40 mm 12V fan.
- USB to RS232 converter for Arduino ProMini programming*.
- Small feet are mounted on the lefthand side for vertical positioning of the cabinet.
- Retractable leather handle.
- Transparent acrylic front cover to protect switches and dials during transport.
- Instructions sheet for envelope- and “next-gate” programming is places inside the cover.
*Note: Disconnecting the +5V supply coming from USB and via the converter board is a good idea.
This is how the rack looks when setup for experiments with a new module:

…and without the cover. The modules are, from left to right: Doepfer A-190-3 (permanently installed), my Super VCO prototype with its extra panel, and a small mixer/gate/envelope module made specifically for test purposes in the mini-rack:
