Erica Synths DIY Eurorack Modules
Folks,
please pay attention that the main BBD delay chips are not included within the mouser BOM project!
You'll have to find it by yourself. They are very rare!
Good luck"!
I'm not able to upload the zipped main gerber file to my pcb maker(jlcpcb). I've tryied merging the drill files, but no success. any idea on how to fix it?
If there happen to be any downstream improvements, the diffs will be impossible to see. I recommend these projects remain uncompressed in simple folders. Thanks
Good day.
I believe that the build guide and BOM for the Erica Synth BASSLINE module are not up to date. The Board files appear to be a version 2 and contain resistors and dip pins that are neither present in the build guide nor the BOM downloaded from the official Erica Github.
Fore example resistors R177 and R178 are not marked as NU and have values next to them but neither the BOM nor the build guide have any mention or reference to these resistors. Same with R179 and R180 and a bunch more.
Is there a build guide and updated bom available for the version 2 somewhere?
Hi! I can't calibrate my Dual VCA. I'm sending 10Vptp saw wave and can't set the same level on output. Is anyone have the same problem?
On the BOM and schematic for the VCO v3 the value for C23 only says 5600 film.
I was able to find C23 on the VCO v2.1 BOM listed as 5600pF film.
I'm very pleased you have open sourced this hardware. It would be good to do likewise with the MIDI-CV software. While you do provide the .hex file, that's of little use if one wants to address bugs or add new functionality. Please consider making the .ino/c++ source code available.
please, provide the source codes and also the kicad files. thanks!
Hi there,
where can I find the kicad files?
This would be really helpful to have them since some pcb suppliers need modified versions of the drill files (and there are some other issues too).
Cheers!

If you plan to manufacture both pcb and panel for polyvoks VCF, be aware that "in level" and "cv in" are flipped in the panel from the Gerber.
There are several of the BOM parts lists that have unavailable parts, what is the best way to get an up-to-date list of parts for these modules?
Hi. I recently finished building the VCO, just in time for support to end. ๐คฆ I'm getting no sound out of it so I'd like to check the voltages to figure out where it went wrong. Can someone please post the voltages at the test points? Thanks.
The cv1,cv2 and input pots are mixed up on the panel
I found that I couldn't get 5V at TP8 as per the calibration instructions and that the voltages didn't step in 1V steps as the switch is moved. I removed R87 (10M) and it worked fine. This was on a v2.2 board but the circuit is the same on v3.
