Modular Synth (Eurorack) - Case

Case

I used a walnut board, cut it to size and planed it to 25mm thickness. I decided to build an 84hp width 12u case, with a depth of 200mm. I cut and planed the boards. I decided to biscuit joint them as I wanted to be absolutely exact on dimensions and wasn't confident cutting dove tails and keeping dimensions to within about a quarter of a millimetre (to fit the racks properly). The back was made from plywood which was stained with a spirit-based walnut dye. After closing the carcass, I used Liberon Finishing Oil (with no sanding sealer). I applied eight coats and then waxed with Black Bison wax.


Power and Mounting the Modules

Doepfer A-100 DIY Kit

I bought a Doepfer DIY kit which consists of two (6U) 84HP rails, a power supply and two bus boards. I mounted the power supply and bus boards on PCB standoffs on the back of the case. I used XLR caonnectors (rated > 2A) to connect the power.

As the rack grew, I bought a second kit for the next 6U.


Second DIY Case

About

This will probably a quickly knocked up plywood 6u case built around synthrack rails and Frequency Central Routemaster power supply/busboard.

Frequency Central Routemaster

I started building two Frequency Central bus board/power supplies to use as a test power supply, with the long-term plan of mounting them in a 6u case later.

Synthrack Rails

I decided to build a case using Synthracks 84HP rails.


Doepfer LC9 (PSU2)

A second-hand LC9 with linear power supply (PSU2) was too much of a bargain to ignore, right when I had just filled the 12u DIY case !


Doepfer LC9 (PSU3)

I built a lot of new modules and was too impatient to build the large case I have planned so I bought another Doepfer LC9 (PSU3 version this time).
