Interest in PCBs for Bruno Putzey's Preamp and Hans Polak's relay volume control

Example Arduino sketch to control VolCB board

I put together the attached Arduino sketch. It controls Hans Polak's 64-step VolCB and 4InputSelect boards. For simplicity, it uses two rotary encoders, one to select input, the other - volume. Use it as a starting point.

Sorry to say this but I have none of the PCBs you are interested in. (I do have a few BPPBP and 16-step volume control board left.) I do not plan another run as there has been little additional interest. Thanks to Hans Polak's publishing the gerbers for his boards, you can order some PCBs for yourself though.

Hi Alex,

Are there any PCBs left. I’m interested in BPPBP AND 16 step Volume board.

Thanks
