Week 03
FabISP In-Circuit Programmer

This week, the goal was to learn how to cut out a FabISP in-circuit electronics board on the Roland Modela (MDX-20?) and then solder all of the surface mount components in place. In addition, I also lean red how to program the Atmel AVR AtTiny (part# ATTINY44A) in preparation for using it as a tool to program other chips.

Above is the final device without the bridge unsoldered.

The CnC machine used was the Roland Modela (MDX-20?). The view button allows you to check on the part and when pressed again the job resumes where it left off. The height of the cutting tool is adjusted manually by combining the up down z axis of the machine as well as setting the bit in the bit holder (via set screw).

This is the soldering room, in the basement of the old media lab (room E15-043). All the parts as well as tools required to solder and program the board were located in this room. I didn't even know it existed until this week!

This was my first attempt, but obviously I set the origin wrong. D'uh.

Here is the final device with bridges de-soldered. I used the wick for the solder bridge and I used the heat gun to get the 0 ohm resistor off.
