Attempting to make an improved version to provide for internal R&D efforts. Updated the PCB design to improve the text spacing on the F.Silkscreen and add a spot for serialization. Etched another PCB and drilled thru holes, slightly nicer than the previous one in a few different ways. Attempted in vain to toner transfer the silkscreen onto the front face for the final time. Decided to just use a sticker for the foreseeable future, as it's not worth the effort for toner, and it's less robust anyway. Just waiting on some ZIF sockets before I can assemble.
