This is the giant controller used for the game Steel Battalion for the xbox.
I used this schematic diagram from a guy called Alpha who did it to his controller.
I put captions to the inputs to help me understand it better, maybe the error in in there.
I finally finished it only it doesn't work as i expected it to. Instead of rumbling when the led light is on (the LED is the interfaced circuitry that's supposed to activate the switch), it rumbles after the light goes off. I'll push the button to test it; the led will light without rumbling, but it'll rumble in the half a second after i let go.
The rumble doesn't work in normal operation when the 5th communication led flashes when i take a hit. If i hold the button for a few seconds, it seems to help as it needed a few seconds of charging. It'll rumble good and then every other rumble will feel underpowered.
I'm not sure what i've done wrong since i wired everything exactly as the diagram shows and triple checked it. Maybe my above description will help you diagnose what i did wrong.
Here's my parts list in case i used something to the wrong specification:
1k-ohm, 1/4 watt 5% tolerance, (wrong wattage?)
2.2k-ohm, 1/4 watt 5% tolerance,
100µF 35V 20% Axial-Lead Electrolytic Capacitor (Maybe i should've used a radial lead? It was a blue one even though both leads came out at the same end. here's the link:

Thanks for any advice. I've tried contacting the guy but hasn't anserwed his messages in a month! Also i was wondering if i could interface a 9 volt battery if after the problem was fixed that the motors wouldn't have enough oomph. How could i do this? I was thinking of just grounding one side of the battery and then putting the positive at the collecter part of the transistor instead of the 5V dc input. Could the circuit handle this without any changes or would it fry anything?
