4th ELECTRONICS PRODUCTION
step1: Download and make the Milling date by Fabmodule.
step2: Milling by SRM-20

This is my first time to use the milling machine, So I need to be very careful.

 

  1. Prepare the tools .
  2. Turn on the power and link SRM-20 to the computer.
  3. Open the SRM-20' driver program.
  4. Fixed the board on the wood board with the 3M double side glue.
  5. Set the XY axis first and put the 0.4mm drill in.
  6. Set the Z axis, adjust the height of drill then fixed it.
  7. Load data and start to work.
  8. When the traces cut is finished set the 0.8mm drill for outline cutting.
step3: Soldering by hand

Electronics parts list：

 

ATtiny44A×1

20MHz resonator×1

1μF capacitor×1

3.3V diode×1

USB connector×1

2×3pin×1

resister : 100Ω×2, 1kΩ×1, 10kΩ×1, 499Ω×1, 0Ω×2

Take all the needed parts out and get ready for work.

step4: AVR writing I use the AVR writer. But the work is not smooth with Windows system so I had to use a mac to finished the writing. First I installed crosspack, downloaded the xcode and the firmware. Then I connected the computer with AVRISP mkII and my FAB-ISP. After that I open the Terminal and write as follows： cd ~/Desktop/firmware make clean make hex make program

This is my first time making board, I learned how to use the Fabmodule, milling mechanic, and how to welding. It's really hard for me, but I finally got my own FABISP.
