Cool concept but as someone that makes quite a few PCBs a year I don't see any use of this for me personally.

Once you get to a certain component size and layer count, home making PCBs doesn't make any more sense.

I do still order only PCB and solder stencil initially to hand solder and test boards before PCBA but by that time I have tested most on breadboards and fitted the PCB in CAD to wherever it will go.

While waiting the 1-2 weeks for the boards and components I usually work on the firmware.
