We have ordered the PCBs for the Fort Processor synth! Initially we tried to use JLCPCB, one of the biggest PCB manufacturers, but getting them to cut the irregular shape we need turned out to be impossible without some redesign work (we would have had to manually panelize it ourselves). So we went with AllPCB instead, they accepted our files without issue and we will hopefully have the finished boards very soon.
Interesting video about the PCB-making process, if you can get past the presenter's irritating style.
Never before has a list gradually updating itself seemed so exciting.
