dam you build like 1 module an hour our what . you are really setting the build progress bar high for us . no really it is very inspirational , glad to see you are having great progress .

Heres the stuff ive been working on.
3x Simple OSC w/Filter, Big Button, AS3340, MS20 LPF, EnvGen, Mixer.
All panels designed in blender for my set up. (130mm panels)
I didnt realise at the time its only about 3mm off standard Euro U, it just felt right in designing.
After building however, I feel 150mm would be easier to work with in terms of wire routing and pcb mounting lol.

Nice color scheme!!!

Great layout. The proportions of your simple oscillator and big button are excellent.

Thanks Jos, im thinking of replacing the white LED’s in the arcade buttons for Blue ones aswell just for a little extra touch.
i’m committing to getting shtuff working before modding LEDs etc tho =D

They’re actually the same size XD It’s just the 3x OSC was printed at 1.5mm thick (Others are 2mm standard) and it cant really take the weight and the 10* lean back on my stands.
so its all curved up lol

I’ve been working on a new power supply for my 2nd 19 inch rack. 7812 and 7912, the usual configuration. For the 5 V part I’m using a dc2dc converter as the power dissipation would otherwise be too high using only one transformer.
I’ve added a front panel this time with an on/off switch, some displays that show the actual voltages, a USB connector to feed occasional 5 V dependent stuff I have lying around and a 16p connector which should make it easier to supply modules I want to try with some power without having to screw them into the case.

Are those standalone voltmeter modules or is there more to them than that?

Those are standalone voltmeters.

Very nice, i like the panel mounted voltmeters, a metal power switch is kinda scary tho. id opt for a LED rocker where possible =]

What else were you thinking of?

Cannot really tell from the photo, but I hope there’s something keeping those heatsinks well separated, otherwise you’ll short the transformer sooner or later.

No worries, they are 1 mm apart and fixed to the pcb, so can not move. Just for good measure I put some insulating tape between them.

do the volt meters do -ve values?

They show 4 - 40 Volts. No negatives, but in my use case it’s a matter of switching polarity and knowing that the voltage is negative.

so freakig cool!
I was thinking about swiping this out of the MFOS and somehow doing bi-color…
but have no freaking idea how to do it lol.

Looks like a series of comparators that go high once the input voltage exceeds their threshold values.

Dual 12 V? Looks super cool as always.

Once wired up, it’ll be adjustable ±2-12V to the left, fixed ±12V to the right, both via linear regulators and polyfuses. Plus raw ±5V and ±15V outputs on the side for future use.
At least that’s the current plan; this thing is modular and easy to reconfigure, so no idea what it’ll look like in a week from now
