Buy one of these instead. A PS2 gamepad to usb converter.

No matter what you post... It makes me happy.

I understand but will the chaining increase the latency of it all or is there no noticeable difference? And can you make a guess at how much LEDs i can power from the linked brains?

btw im getting really excited about this method. Im goin to buy 4 controllers this weekend and start testing. Awesome post!

That's what I used for the Leo Bodnar device, which is the same thing really - a game controller. I believe I read somewhere on here that the size of the pot isn't too important, but the fact that it is linear is. I seem to remember someone saying 10 -100k will work, but 10k is the standard.

I can't find any of the post to quote it though.

Milo, the pots are 10k. Somewhere I read that you can use up to 100k pots as long as you are using all the same value.

btw, the newer xbox360 drivers from microsoft work very well too; latency nil, the driver has a configuration control panel that's way versatel, buttons are reassignable, Fergo's Joystick loves it. I've been messing with Ableton with these. Only 2 stacked so far with great results. I believe the remark about handling up to 4 is correct with the redcloud driver. It might be more with the microsoft ones.

I'm having a bunch of fun with this, sounds like you guys are too. Woohoo!

Post a photo of the gamepad opened. A lot depends on what type of pcb you have in there.

Then if you're serious about doing this, the first thing to do is de-solder the vibration motors, then the joysticks. You will not require the vibration motors. De-soldering the joysticks will help later on when you fit pots to the connections. There will be at least eight connections per joystick - 6 analogue and 2 (probably 4) for the joystick button. There will also be two solder joints which are used as fixing posts on the pcb. That's just for starters, but don't let it scare you.

Anyone tried to do a controller from ps2 pad. It looks quiet complicated on my pad.

unsure about latency - it's definitely something that would need to be considered whilst testing.

LED's could be powered directly from the USB power but I believe you're after a midi brain that allows you to control, via midi, when the LED's get activated, which is something that a USB gamepad (like the xbox pad) doesn't offer, unfortunately.

good idea - I'll probably do the same once I've soldered everything else on to the circuit board... just need to do some tests with various potentiometers first...

Just to say this inspired me to try this too.

Just mocked up a quick test using the supplied driver and one button hooked up to an arcade button and SUCCESS!

Although I would recommend not splicing the cable into the xbox cable. What I did was unsolder the original cable from the PCB and solder in a usb cable back in. Much neater.

The pads aren't too bad to solder to, just use a sharp blade to scrape off the carbon contact to reveal SHINY!!! copper track, the track must be shiny otherwise it still has crap on it, the way I did it was to scrape off the track just as it turns into the pad and then lay your wire ontop of the revealed track, that way you get a good solid contact area.

the answer is yes and no, the solder pads are nicely spaced out for the analogue nubs but some of the digital pads might be trickier to solder... have a look:
