It seems to have taken forever (at least from my perspective) but last week I finally sent my Eagle CAD files to OSH Park to have boards made. At this point, they are already out at the PCB fabricator and I expect to get them by the end of September.
This is my first time sending files out to have a board fabricated, everything else I've done has been with perf board (point to point soldering), strip board and single sided etched or CNC milled boards.
This, present, board is mostly surface mount parts (to save money and space). My
experience with soldering surface mount parts is very limited so I used larger package sizes (1206 for passive components) for components to make it as easy as possible for me, and others, to populate the PCB.
I tried my best to include the ability to add more memory of functions I haven't been able to test yet (EEPROM chip to expand functional memory, and an additional button for data entry). I really want to add capability to transfer data to computer/phone/cloud, that will have to be a future addition.
I'm posting the current schematics up, by 9/16/16.
