This document outlines the 7 steps to produce a FabISP electronics board using a Roland MDX-20 milling machine: 1) Work with the circuit board and setup the milling machine. 2) Install the board and milling tools and download files. 3) Problems were encountered finding the correct files but the board was eventually installed properly. 4) Gather additional tools like a soldering station for assembly and testing.

summary
-This week assigment is to make a FabISP.
-using Roland MDX-20 Milling Machine
-for this we will have to programmer in-circuit
academy
-then assemble the SMD components, test for shorts or open circuits and then
test and program the FabISP.

-upon completion of the construction of the card
- Then following the tutorial I installed the AVR programming software and Fab academy
downloaded the firmware.zip file for programming the FabISP.
-Testing and programming the FabISP

1. This has been a hardwork, especially . We had to calibrate the table of the
milling machine,

2. When connected the ATTiny to the programmer, first we got a red light, so
with the multimeter we measured the voltage supply of the ATTiny and found a
short circuit, wich was fixed.
3. I asked for help to our colleagues, for the programming, the support was
