I spent most of today making up the boards for my new robot and, oh boy! Maybe it’ll be fine. I started the day trying to figure out how to best use the space in the blank PCBs. The supplier didn’t have any of the stock I normally use, so […]

This was the state of my front IO connector PCB after I tripped over the USB cable, yeah not good. I figured I could make a replacement board, but before going that far I thought I’d try to repair the existing one. The first step was to glue the fragments […]
