First modular PCB designed!

It's the old adage, best become a dealer to support your habit. My plans for a small-scale modular fabrication lab in my garage are in full swing. My MyDIYCNC kit is half built, hopefully finished over the weekend. Below is my first modular PCB design. It's a true spring reverb driver module. It drives the sound through a widely available spring reverb tank like the MOD 9EB2C1B Reverb Tank from Amazon, with adjustable EQ, mix, and drive settings. I did not design the circuit, it came from this muffwiggler forum thread. I plan on releasing the EAGLE design files to the public once this is finished! Some pictures! (Sorry for thumbnails, it's that or the wide images break my blogger template)



Before selling modules I need to sort out an HPLV spray gun & compressor tank for painting the metal panels before etching, but other than that it's all things I've done before. Exciting! After this I think my next module will be a true tube overdrive/distortion, then some classic filters. I'm looking to build an tonally incomparable FX rack :) Interested in purchasing any of my built modules? Contact me!

So you're in Ottawa? Might be interesting to touch base with you - I used to do PCB board milling, was just thinking of using one for a new project as I'm looking to build a few things myself so there might be an opportunity there if you'll do related fabrications?

P.S. Doing a lot of electronics myself...

Hi! What are you looking at building? I have my Cnc running but not yet reliably. Once it is though I plan on doing cheap pcb milling for people. My Cnc is very slow so not really usable for 3d parts unfortunately. At 2 ipm it's prolly quicker to get it shipped from china :)

sorry for the disconnect, lost the thread... maybe you've sorted out any reliability issues by now? I'm into synth circuits, double-sided stuff that I'd like to build, nicer with a real board, but not sure how practical it would be via a milling machine..

Prototyped on breadboard with the intention to install into a Yamaha CSY-2 Synth Organ: Thomas Henry XR-2206 ring modulator, T.H. 4046 Sync VCO, Multi-channel C.V. & Audio Mixer, Yusynth S&H Module, Elektor Formant White & Pink Noise Generator, Super Ladder Filter Core (just the LPF)and input audio and CV mixer

The above modules expand the capabilities of the CSY-2 into something far beyond the original creative and audible capabilities. I'm also considering tying in a PAIA MIDI- C/V unit to allow direct connection to my midi/audio setup.
