A variation on the classic CMOY design. This one uses significatly more power filtration and a higher end opamp. It also runs at 18v for increased headroom. Its currently a work in progress with changes on the way. The PCB will be designed to fit into an altoids tin being locked in place by the mounting hardware of the pot and switch.
The source files for the PCB have been posted to Github, you can get there by the link on the left. The PCB files might be incomplete because I had some second thoughts about the design, I will be updating this in the future when I get more time to put into it, expect the next update to be finished with a possible prototype fabricated.
