This was my first experience with circuits of any type, so I was very excited. Since everybody had the same assignment to fabricate, stuff, and program their board I’ll mainly just show some cool pictures.
I downloaded python and everything else that was needed (which is quite a bit) to use cad.py on my PC. Then I pulled up the .cad file from the assignment sheet to make the .g file.
Then, I downloaded ReplicatorG so that I could run Ilan and Max’s awesome machine from my laptop and made the .g file a .gcode file.
I was fortunate enough to mill the very first board from the new machine! We then milled one more for another student (who ran the machine off her mac) and then I milled the board I needed to program the Hello-World board.
While I had done some soldering before, I had never done any surface mounting and especially nothing with this small of components. Unfortunately, I don’t have any action shots because I only have two hands and I needed them both to solder!
Notice the rework on the far left diode. I destroyed the original pad trying to connect it the first time and had to use a small piece of tin-coated copper wire to get it to work without remaking the board.
First, I needed to make the cables. The female DB9s gave me a little trouble…
I then borrowed some USB to serial adapters, downloaded the necessary drivers and tried to send the code.
Crossing my fingers…
And it worked!!!
Overall, this was pretty awesome. Mainly because I had never done anything like it before and I really enjoy new things!
