Week 4Assignment: make the FabISP in-circuit programmer
Programs/Machines:Fab Modules, Roland Modela MDX-20
Lessons Learned: Be careful soldering as not to flood traces with solder and pay attention to drill bit sharpness when milling your board on the Modela.
This is the first week of electronic production. I have never worked on creating an electronic component from the ground up. I have worked with Arduino and processing before, as well as wiring house-hold electronics but this will be a new experience for me. Our assignment is to mill and build a FabISP in-circuit programmer. What a FabISP allows you to do is program other boards that have microcontrollers. Programming of boards occur through the connection with a USB cable and a six pin header, which connects to a six pin IDC cable. The components of the Hello-ISP board are all available within the FabLab inventory. I would recommend familiarizing yourself with the Fab Modules before continuing.
Roland Modela
The Modela's primary job within the Fab Lab is to mill printed circuit boards (PCBs). This tutorial helped me greatly in understanding constraints of the milling process.
Starting the process:
-Download the FabISP traces and interior
-Look over what components need to go where here and view what it should look like in reality (without the bridge resistors)
-Stick your copper FR1 to the sacrificial board on the Modela with double stick tape, or tape it in a way that does not interfere with your milling.
