Finaly, we received milling tools and made the PCB for FabISP with modela milling machine.

Had some problems at first, specially with milling cutting tools and adjustments, but are already solved.

Surface-mount SMD components is more difficult than it looks, I started by soldering small regions where need to put components, more precisely their pins.

After that, I started soldering the small components, and ends to soldering mini USB socket.

We shoud have carefully by not overheat the components, specially integrated circuits, so don't stay much time to melting the soldering alloy.

After finishing hardware stutff, we should programing our FabISP, well, that's a problem, we don't have got another programmer but an arduino.

I used an arduino duemilanove (atmega 328) as an ISP programmer (arduino ISP), followed instrutions by here:

http://hlt.media.mit.edu/?p=1695

http://hlt.media.mit.edu/?p=1706

So, I had programmed de ATiny44 with some exemples from arduino software with success.

I tried to transfer the FabISP firmware to my "FabISP" with Ubuntu 12.04, using ardunio as ISP programmer but had some problems to reconize the port. Arduino IDE and 1.0.3 software reconize arduino hardware (both installed in Linux) but, when tried to make all the necessary steps (make clean, make hex, make fuse, make program) using command line, it stops in make fuse command.

And yes, I changed makefile for arduino ISP and moved #, but I did not used sudo command for make fuse (maybe it is the cause???).

After all, I get an AVRisp mk II, edited the makefile file and programmed my fabisp successfully (fix, before, a bad contact detected).
