My build progress

yeah thats the only way to go it makes so much easier . the only problem is you end up with a wall of these things to !

Did you get them in the Euro Bundle or are you going to do your own Pot Board and Panel?

Assembled - tested - and it works (with some minor bug fixes).
To summarise I call my first design and build a big success. Thou this is only the first iteration. It has one big issue that I somehow missed - it won’t mount in any regular eurorack case, as I didn’t leave enough space between top PCB and mounting rail.

Forgot to readjust the jacks after putting on panel and before soldiering.

It’s a shame I’ve never seen knobs that are little wasps. It looks brilliant.

Congratulations! Made a first module and a double dekker at that! I find the mechanical part the most difficult when designing a module, therefore I always check the layout is confined to the space between the rails so that I do not position anything past them or too close to the rails (I’ve been lucky a few times in the past).

From the first image I get the impression that you wouldn’t be able to use any nuts on the rotary encoders or would you thing you wouldn’t need any? The jacks seem to be as high as the switches, so those look fine to me.

I write this mistake down to the fact that I don’t have a rack jet, so I just didn’t think of that.

Those are potentiometers with same dimensions as a regular Alpha one. It is just weird perspective of the picture. They fit just fine. Thou I don’t like the high profile of these switches. I have hard time finding switches I like.

I feel the same about the switches. An alternative way of mounting them is to use a nut on either side of the front panel. Then you can have them ‘end’ wherever you want. You will however need to mount the switches and jacks differently then ( not on the pcb ).

My first PCB design was too big for Kosmo, I now have template files for PCB and Panel so should never have the issue again.

The up side to making your PCBs too long is you end up with a cool plaque to mount over your workbench

This week work is telling us,

“Don’t plan to do any work, but plan to always be available to work”

So I spent the day doing 5 mins evey half hour checking e-mails and our work queue for urgent issues. All was quiet…

So I productively kept myself available.

I created a KiCad Component and Footprint for the “PB-86” push button ( love these )
I created a PCB and Front for a button/display module for a DMX controller project.
I updated and finalised my TunerVco, I have altered the “Link” to send the REF voltage.
I updated and Finalised my BussBar
I updated and Finalised my Kosmo PSU revisions.

And sent them all to JLC …

And got home to find my last JLC order for the CheapStep Revisons and My DMX controller main board.

Tomorrow I am going to take a look at my failed ADSR project, see if I can find an Issue.

Holidays are super busy for me, glad to see progress for the CSP though, that thing is awesome.

hopefully found the issue on my AS3310 ADSR design (Credit @EddyBergman Design) , corrected that and a layout issue on it’s front panel (offset vertically too far ).

Slipped that into the growing JLCPCB order…

Going to be busy, I need to start replicating my workbench setup (component stack ) from home to the workshop. And buy another half decent iron.

My T12 clone is the jam.
Heats up super fast and the handle end has a nice flexible silicone cable. There are also nicer aluminum versions as well if you want something a little fancier.

If you have a spare laptop charger 24v 3A+ you can get one super cheap. else its 60USD for one with a built in psu.

This eves project - panel wiring of the Simple AR Envelope. I regret not thinking ahead and making this a dual AR panel. Always V2.
Used a stomp switch that I’d misordered before knowing what a momentary switch was for my trigger.
