Mitocondrion Mark 4.1 Build: Main PCB
So, here's the board being made, from design, through masking, etching, building and testing the step-down power converter, and then once that was checked and working, populating the rest.
( Great big pic under cutCollapse )
The status LEDs are the smallest things I've ever soldered, 1.6 mm long and 0.5 mm wide. It was a mission to get five of them in place, even getting them out of the packaging without losing them was a mission. Admittedly, there's supposed to be six of them. One is now on the floor somewhere. Can you spot the missing LED? Hell, can you spot the five LEDs in the picture?
So it's built, but mostly not tested yet. As I mentioned, it does a lot of different things.
