This tutorial building the FabTinyISP, help me to fabricate my FabISP. I took soldering iron, tweezers, lens, solder, components and a Modela MDX 40.
I downloaded the PNG files for the traces, the board outline and the Fab modules to convert the files and send to a Modela MDX 40.
First I acess the Fab modules web site and upload the traces.
Chose the machine Roland mill .rml as out put format and the tool PCB traces 1/64 to mill internal traces.
tg(15)=x/2 :2
x = tg(15) x 2 x 0,2
x = 0,1 mm tool diameter
Then the main parameters are about the Modela machine, and we are using the cut deth 0.2mm tool diameter 0.1mm and number of offsets 8
Then Calculate and Save and after this ...
... send to Modela software in our case is the Vpanel
After the milling the PCB, I remove a bit of cooper note that It is important to do with care, I removed one board trace and lost one PCB milled.
To organize the solder practice I separate the components in my noteboo, for more details see this tutorial building the FabTinyISP.
Materials
1x ATtiny45 2x 1kΩ resistors 2x 499Ω resistors 2x 49Ω resistors 2x 3.3v zener diodes 1x red LED 1x green LED 1x 100nF capacitor 1x 2x3 pin header.
The soldering technique that I was using was inappropriate, and my tutor Kenzo Abiko. help me to not put solder in all board places (connections) before the component. To have better connections the advice is to put solder in half of components connections ("legs") and so, solder the other component´s ("legs"). The technique is so important to make the best board.
The difficult is the ATtiny45, Zenner and the LEDs that need our attention about the orientation.The tip is that the Attiny (circle mark) and Zenner (line mark) have the same direction in the board" (see red mark).
But I have "heavy hand solder" then I had to clean ( Isopropyl Alcohol) and sanding gently to have better connections in the USB computer. Thanks to my tutor Kenzo Abiko.

After tested several times without sucess, my tutor Kenzo told me to reinforce the FabISP base with a tape to a better connection with the computer. After that, it was connected better with USB computer and was programmmed.
