I got a case for my modular synthesizer.
|The finished case|
I got inspired by this thread on Muff Wiggler to use a basic tool case to host my first modular synth.
I reckon my initial idea of 2U 84HP utility panel would have taken me too much time. So starting from an existing box seems a better idea.
As usual with me, I progressed step by step.
The box is a standard tool case from the local DIY store (Sencys from Brico). External dimensions are 46 x 33 x 15 cm. This is great for hosting a 6U 84HP Eurorack modular synthesizer.
I'll keep the lid from now.
The Doepfer A100 DIY kit is perfect for the job : four rails, two bus boards, a power supply is all you need to start..
|Checking everything is in place ...|
I started by checking that everything could easily fit into the box. And from there I evaluated what would be needed to mount the kit inside.
Apart from the box, I exclusively used pieces of woods already available in the house. Mainly remnant from a 6mm thick MDF wood panel..
I decided to keep the foam inside. I only had to tighten the corners and cut out the part where sides were recovering the bottom part.
I bought some 6mm x 6mm square nuts to fit in the rail, as the standard hexagonal ones have a tendency to rotate and block into the rail. As I miscalculated my needs, I kept 4 hex nuts per rail, two on each end, for a total of 21 nuts per rail. I reckon this will suffice.
The back of the structure is a bit more than 4 cm deep. It gets to support the power supply placed vertically and can accommodate 2 8HP modules turned horizontally. Not as good as the 2U utility panel I initially envisaged, but this will do.
For the bus boards, I decided to fix them from below an horizontal wood piece. These slats were a bit thick. The box is not very deep. This way I keep a full 7 cm clear. The bus boards are blocked by the foam. And yes I checked if, by any chance, this would be conductive … which it is not, obviously.
The connection of the power supply to the 240V-15V AC transformer is done via an appropriated connector on the front panel to avoid piercing the box. No trouble thanks to the parts I collected when I started to make guitar pedal kits.
A green LED connected between the -12V rail and the ground (with the help of a 1k resistor) indicates when the case is powered.
Both fit into a custom panel, drilled with some ventilation holes.
I made sure the power wires would stay nicely on the side and I double checked the connection with a voltmeter.
