( h o w . t o . m a k e ) a microcontroller pcb
responsive environments group :: MIT media lab
This week's project was to add to a pcb design and program a microcontroller in assembly code. The micro of choice this time was the ATtiny44. The second time around milling a board was easier, but not without complications. The sacrificial layer on the Modela machine was not level, and the first few boards came out with shorts all over the place. After we adjusted the material and set the cut a bit deeper, the boards were fine. Designing layouts with cad.py can be confusing to those used to a graphical cad.
