Assignment Week4
Electronics Production

This week's final project is "make the FabISP in-circuit programmer"

I milled PCB board, soldered electric parts, and install program.

I was told information of Waag"s FabISP from my instractor.

So I tried to make this.

Milling

First, I milled PCB board.

I used Fab Module and MDX-20.

1. Start the Fab Module in Ubuntu

2. Download the circuit data of Waag"s FabISP.

I downloaded "fabTinyStar-012.tar_.bz2_.txt V0.3 (Bas)". 3. Make mill data of FabISP using Fab Module. Then, we need to change parameter for milling

>for mill circuit pattern of circuit board : change "offsets" 4 to 2 , and make.path > make .rml > Begin Milling > use 1/64 inch bit

>for mill outline of circuit board : change "top" 0.6 to 0 , and make.path > make .rml > Begin Milling > use 1/32 inch bit



Milling.

Done.

Soldering Electric Parts

I solder FabISP's electric solder aspirator.

These parts is very small. So, at first, I put solder on pattern of PCB and aspirate, using solder aspirator.

So, very little solder remain.This is enough for soldering surface mounting parts.

I couldn't get PCT thermistor for protect circuit. But this is not must use.

So I use 0 ohm resister insterd of PCT thermistor.

Install FabISP

I use AVRISPmk2.

I download make file from Waag"s website. And I read this tutorial site.

Following this tutorial, I downloaded "vusbtiny-fabtinystar.zip" from Waag"s website.

This tutorial site use Arduino Uno to install ISP. But I use AVRISPmk2.

So, I change programmer setting in "makefile" of usbtiny folder.It can upen in textedit application.




And type make install following tutorial.








I checked the system information of Mac.So Mac could have recognize FabISP.
