sabor awesome shift register boards

oshpark: 6 dollars per 3 board (5cm x 5cm) - prototype service
http://docs.oshpark.com/services/
- i probably order my first board from here.

dirtypcb : dirtypcb wants *edge.cuts.gm1 into *.gko extension
lionscircuits: http://www.lioncircuits.com/ - looks promising for small number for prototypes.

On my home PC, the menu icons were absent in kicad somehow. running this command fixes those:

$ gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>}"

put 2.5-3mm space between each pcb as 1mm space would take up by cutter tool.

Kicad setup guide

first time setup.

Setting folders for lib,footprints and 3d shapes.

create a dir named "Kicad" in ~/repos/
cd Kicad
git clone https://github.com/KiCad/kicad-library
git clone https://github.com/KiCad/kicad-packages3D
git clone https://github.com/KiCad/kicad-footprints
open Kicad
Go to Preferences -> Configure path ->
KICAD_PTEMPLATES -> /home/ami/repos/KiCad/kicad-library/template
KIGITHUB -> https://github.com/KiCad
KISYS3DMOD -> /home/ami/repos/KiCad/kicad-packages3D
KISYSMOD -> /home/ami/repos/KiCad/kicad-library/modules
open any sch file and do following things
Preferences -> component libraries
delete all components library files click add -> go to /home/ami/repos/KiCad/kicad-library/library and selet all .lib files.
