Hi everyone,

Since speaking to Ralf at RandomSource and realising there are no more PCBs available for the Haible Living Vocoder, I've taken it upon myself to redesign the Living Vocoder using Jurgen's original schematics.

So far, I have a filter channel PCB, using SMD components for the parts common across all the channels.
I also have the Slew/Freeze, Speech Input Amplifier, and Synthesis Compander PCBs laid out in Eagle. I'm working on the others too.

Since Jurgen always designed his circuits with the DIY community in mind, I'd like to offer my work to you all here, so we can collectively bring the Vocoder to life in a form that is slightly less daunting to build.
(The 20-channel filters will be easier to solder if half the components are already on the board in SMD).

If anyone's interested, I can upload my eagle layouts to a github page, so we can all double-check and debug, with a view to getting some PCBs manufactured and soldered.

What say you all?
