I saw this posting a few weeks ago on Hack-a-day:

This afternoon I attempted something similar, with a few adjustments. I cut the head off the 6inch 3/8ths bolt so that a shifter knob could be installed directly, and instead of the spring I just used a short piece of 5/8ths fuel line with a bolt fixing it to the bottom of the box.

Next to get a cheap chopping board to make the 'H' pattern and a 2nd hand game controller to wire it up...

Picked up a cheap $5 cutting board and went to work.

And the result looks like this.

General thoughts are that the gates are a little too wide (so will have to make closer on the next one), but apart from that it shifts OK. When you drill/cut the outer gates (gears 1,2,5 & 6) remember that the shaft will be angled, a keep checking against you base that the shaft has enough travel to lock into gear.

Next is to find an old game pad to rip apart...

Cool. Are you going to put some kind of switches in it to indicate (to the game) which gear you're in?

Yep, the idea is to rip apart an old gamepdad and use that for the USB side of things. A better, more professional approach would be to use an Ardunio/Teensy/etc to do a custom HID device.... but I'm just mucking around at the moment.

Probably will just use paperclips to short across the steel shaft, micro-switches would be nicer but I fear there's not enough space for mounting them for 3rd and 4th gear.

You will see from the pictures that I have cut extra bits to make up a second device when I've mastered it.
