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.

-Then we setup the MDX-20,
                                                                                  academy
-Installing the board on the milling table and also the milling tool (1/32" for
cutting and 1/64" for milling).

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