this is how mine looks
i pretty much used this thread as a guide
Official AXISdapter Thread: SIXAXIS/DS3 Hacking Made Easy
specifically this PDF http://www.geocities.com/shinjn/Intro_AXISdapter_v2.pdf
i used a USB mini b cable like this one
i use the cable for charging, syncing, and to use on the PC. tho i could run it wirelessly
via bluetooth. i believe there are drivers to do so but ive yet to try it.
and modified the smaller end so it would just be the connector with out the huge
protective jacket around it. i then covered it with some heat shrink.
the PS3 PCB is not a common ground so in my case i needed to modify the TE
terminal strip so that the were 3 commons (left, right, center) the commons are
all described in the PDF above.
aside from that, the stick is the same as any other stick and wiring is very straight
forward, you should have all you need info wise with the sixaxis adapter thread.
let me know i you have any Qs
