Every other week I meet up with the fine audio geeks of "Bay Area Modular". Here we discuss life, liberty, if Behringer is modular methodone, and the final -2db off the noise floor.
An ongoing project/meeting recently completed: members proficient at audio DIY showed the less civilized members how to lay out and build a complete Eurorack synthesizer module.
The build chosen was the "Farm VCA" from the website here (the original post from a server in Japan appears to have been taken down...but its open source design lives on....)
This time we go over the successful outcome: a simple EuroRack Voltage Controlled Amplifier.
The two boards (main board and front panel) were laid out in Kicad 6.0 by Elton at Otter Mods and the rest of the group.
My sponsor, PCBWAY, generously donated the PCB fabrication.
(Great news--except for a blown up trimmer--my fault!--the module worked first time, no kludges, no rewiring, no fixes.)
Here's the finished module:

 |
| Wrong trimmer--should be 100K, not 100R. Oops, blew it up during my intial test, but it was easily replaced. |
 |
| The group laid out the board with components occupying both sides of the PCB to get the design into a 3HP configuration |
 |
| Elton testing the module in his rack |
 |
| Works--Rack em! |
Get the schematics, gerbers, BOM etc., from PCBWAY's project page, here.
More analog hardware? Less Digital? Less C nonsense? Bring back Arduino? We can only hope.....See you next time!
