DIY Synth VCO | Part 2: Designing the PCB
HTML-код
- Опубликовано: 2 авг 2024
- So far in the DIY VCO I've managed to lay out the ground planes front and back, route the traces and condense the board, it's been proto-typed and on the way so we'll see how it turns out!
Here I'm showing the progress of the PCB design I'm working on, it was converted from the original CEM3340 stripboard design on Sam's website, further modified with advice from the members of the LMNC discourse and of course Caustic who helped quite a bit and so yeah... you should check em out! Links below, hashtags all that good stuff!
My contributions are only to convert this to schematic file from stripboard picture form, I designed the PCB, I've added a eurorack power header, added 1k output resistors, power filtering and decoupling and put it into PCB form, I've also included mounting holes to make it easier to mount (no need for driilling)
The original location of the CEM3340 stripboard layout that this was copied from can be found here:

The added Hard/Soft Sync, FM and Square wave filtering was added by Caustic, and can be found here:

EDIT:
If you want to follow the ongoing progress you can follow that here:

I will test the board, and verify my findings once it gets here, so if you'd rather wait on the next part, that's okay too!

Been great watching you find your vco-ation ;@)
I'm glad they've been enjoyable :D I worry I come across as boring a lot of times haha
@@SpectrumDIY There are different ways to watch a video. It is genuinely encouraging to see someone else learn the ropes and succeed, whatever it is they're succeeding at. It means that I might have a chance too when I decide to try something. It might even be my own synth - who knows! I don't.
@@ymirthefrostgiant I really love that! *Pinned* :D I can't wait to do the next bit, I've been having a lot of stuff going on in the background, but it's all repetitive so I figured I'd just culminate until I've got enough to info dump into 7-10m video (been trying to keep it shorter and sweeter if possible, something else I'm learning as I go XD)
@@SpectrumDIY lot of stuff going on... repetitive... culminating into a 7-10m vid... sounds like you're already synthesizing your next dance beat, man!
There might be quite an update coming ;)
Nice. I got more than expected. I have not considered the full-up PCB, but now the challenge for proper engineering is a must. No more slap some solder on it to make it go. Crossing the T's and putting dots in the right place just make sense.
very cool :)
Lookin' forward to seeing the prototype, mate!
The boards made it to the states today, so not too much longer😁🥳
The AS3340 text is left intentionally as you can use either AS3340 or CEM3340, Minor differences in power resistor, I think is 10k vs 51k, but otherwise they are the same.
