This week's challenge? To manufacture, solder, and program your board - from scratch! We started with copper boards, milled them out, then stuffed the components onto the board - and finally, hooked the board up via the AVR programmer and got it set up in terminal.
The traces for the conductive pathways.
Component plan for soldering the circuit.
First, I milled out the copper boards on the modela mill. I was lucky that I had a really sharp end mill at the time so my traces came out perfect on the first try! An unusual feat, I know.
Next, I soldered up the board making sure to be really careful with the delicate and small components, such as the USB board the 6 pin header. I double checked for shorts and bridges with a multimeter and it all checked out.
Finally, I hooked up my circuit to the AVR and got a green light - indicating that there were no shorts and that I could proceed with the last step: programming in terminal!
I am super excited about using this circuit board to code cool things in the future! I was also pleasently surprised as to how easy it was to manufacture circuit boards in house - which could potentially save me a lot of time and money over outsourcing to PCB manufacturers.
