Week 2: FabISP in-circuit
Programmer
I chose the Valentin board design because I found the snap-off
functionality clever. I have never fabricated a PCB before, so
this would be a learning experience.
Step 1: CAD/CAM
Milling the board on the Modela was super straight forward. Using
the fab module, I only had to set the Z axis myself- everything
else was a click or two away from pressing go.

(Note: someone left their tape to the left! I know, I should have
cleaned it up. Next time!)
Step 2: Clean/Prep for Stuffing
Cleaning was easy as well, simply scraping away the milled copper
with a straight edge ruler, and then washing the board with water.
Step 3: Stuff+Solder
Stuffing was fairly easy. Soldering, on the other hand, will need
some practice to get more consistent as well as faster. The whole
board took me around an hour- should be more like 10-15 min.
I would like my solder connections to be cleaner and smaller, but
for now I think they should work.
Step 4: Test/debug
To be completed once I locate a programmer!
