completed circuit board

This week we were asked to produce an already designed circuit board in order to get a basic understanding of the general workflow.

The process begins by milling the circuit board followed by soldering the components to the board, and finally programming it via a computer.

In general, the process went pretty smoothly and surprisingly quickly, though the milling machine was a bit finicky and required restarting multiple times.

moving the origin to the least touched part of the board :

After running the trace and outline, I decided to make an additional circuit board. I wanted to have a back up in case soldering went south, but I was also curious about making the offset 0 vs the default 4.

running trace with offset 0 :

excess tape (suggested by paloma) makes pulling board off easy :

popping off the board with spatula :

difference between offset 4 and offset 0 :

gathered all of the required components :

began with the ATtiny to have the most access :

after sautering :

connecting to the programmer :

i had to manually add the USBTiny for it to be programmed :

programming successful! :
