The circuit in the controller can only see voltages, and the pins on the circuit are pulled high by a resister attached to 5VDC, which comes from the xbox, no battery required. What this circuit does is use that five volts to make a circuit that fluctuates between 5 and gnd(also from the xbox). this signal is not sent to the controller. Rather, the fluctuating signal is sent to the two transistors at the bottom of the schematic. These basically work as electrically controlled switches, turning on and off. one side of the button is attached via a mess of circuit board and wires back to ground, so it works the same way, and you don’t have to solder anything to the button contacts themselves.

It doesn’t make sense to me that there **aren’t** four wires that come out of the schematic **that** go to the triggers. Two wires for each trigger.

Could someone tell me where these four wires go to?

1) +5v
2) Gnd
3) Right Trigger
4) Left Trigger

I want to use this device on a 360 controller. Do I buy a 5v battery and hook up 1 & 2 to it?
The triggers on a 360 controller have two leads going to them. As I would think all switches do. Which right trigger lead do I put 3) on? Similarly, which left trigger lead do I put 4) on?

It doesn’t make sense to me that there are four wires that come out of the schematic and go to the triggers. Two wires for each trigger.

#16 (stephen) pretty much any 555 timer in an Astable configuration would work. Here is some good beginners info on building 555 circuits: http://www.kpsec.freeuk.com/555timer.htm
