I’ve been working the past several weeks on my traditional summer activity, expanding my synth cases (too cold in the garage workshop for woodworking in winter), and reassembing Kosmodrome. I’ve added two rows to the bottom of the second case.

A wood case, unfinished on top because it's meant to bolt to the bottom of an existing case. It is built from dimensional pine, with cherry stain. There are extruded aluminum rails with slide nuts, and three blank panels screwed to them.

Kosmodrome case extension

A wood case, consisting of two rows mostly filled with synth modules above two more rows that are empty except for three blank panels. It is built from dimensional pine, with cherry stain. There are extruded aluminum rails with slide nuts. It sits on a cluttered work surface with a 3D printer to the right.

The woodworking is, erm, imprecise, and the finish is positively slapdash, but good enough.

I assembled and built two new bus boards for the two new rows, and one new power display module (I had one spare already).

I redid the power distribution from the power supply, replacing terminal strips with Wago lever connectors with more capacity. Yes, I’m using one 40 W power supply for all four rows. Should be all right, yes?

Three 5-position lever connectors mounted in a green 3D printed housing and screwed to the inside of a wood case. Five each of red, black, and blue wires go into the connectors. There's a blue plastic electrical box on the left.

I basically took all the modules out of both Kosmodrome cases and put them back, in a different order, adding the recent modules that had been left out due to lack of space. In the process I found one module that needs troubleshooting, and I knew about another, so I’ll have to work on them — I didn’t screw those two down. I hope to get a better photo later but for now here’s a quick phone picture.

A Kosmo format modular synthesizer. Two wood cases, each about 70 cm wide, one with two rows and one with three, mostly filled with modules and some blank panels; there's one empty space.

The cases now are big enough to accommodate all the recent modules and some future modules — though most of the empty space is already allocated to modules I plan to build in the near term!
