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) Mill the circuit board and install it on the machine along with milling tools. 3) Download design files and mill the board. 4) Assemble surface mount components using soldering equipment. 5) Program the ATtiny microcontroller and test for shorts or errors. 6) Install programming software and download firmware to program the FabISP. 7) Power on the completed FabISP and conclude the process was challenging but completed with colleague support.

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

conclusions
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
