Hi there,
for having fun with the great Sanwa Sticks I want to use a transparent Balltop and a Stick with a hole.
Thanks to luigi for the necessary hardware.
If you want to make it lid RGB you are in need of some SMD Led´s. First I tried SMD 605 (small Leds) but now I will try the bigger one called PLCC-2 DMX RGB-Leds.

pinout plcc2-rgb
IF=20mA, Red=2,0V; green=3,5V; blue=3,6V
-> Rred=150Ohm; Rgreen=125Ohm; Rblue=120Ohm @ 5V
You need 4 wires and shrinking tube.
