[sdiy] PCB / Panel Manufacture

I like Sam Battle’s LOOK MUM NO COMPUTER videos, and in fact it was exactly that VCO video in CJP’s link below which inspired me to build the CEM3340-based VCOs in my pictures (Thomas Henry’s VCO MAXIMUS, www.birthofasynth.com/Thomas_Henry/Pages/VCO_Maximus-Resources.html <http://www.birthofasynth.com/Thomas_Henry/Pages/VCO_Maximus-Resources.html> ).


Sam often builds something that he plans to use in a live performance, so you notice that he actually takes a lot of care to make it simple and reliable.


I’m looking forward to seeing more pictures of real-world-working non-perfection…

I recommend "look mum, no computers" on youtube.  He's pretty funny and he cobbles stuff together and it works.  His panels are black spray paint and silver paint marker.

Here's one of him doing a VCO:  https://www.youtube.com/watch?v=4Kz8YopLTCQ

Hello and welcome, I’m also fairly new here.


I’m in absolute awe of the amazingly professional hardware that everybody else seems to be building; my ShedSynth is a bit more home-brewed:



I wonder if anybody else will admit to hacking together stuff like this?


You asked about simple modules.

I started with an Arduino pretending to be a not-very-1V-per-octave VCO and Hendrik Göttling’s “Ultra Simple VCF” (www.electro-music.com/forum/topic-45231.html <http://www.electro-music.com/forum/topic-45231.html> ) which turned out to work happily on dual rail supply.


Best of luck making some noise.

I don't know if copper trace thickness should be a concern. Obviously with power PCBs and distribution boards you want wide traces and I have done some research to try to learn how wide for certain amp loads. Really, any advice will be good for me - anything that you wish you had known before your first order could be helpful.
