Changing Xbox360 analog triggers to digital (on/off)

Pages: (1/2) > >>

Ballard:

I'm trying to get the analog triggers on an Xbox 360 controller to work like a normal button. Rather than the analog of somewhere in between. On episode one of the Benheck show (11:30ish), Ben shows you how to do it, assuming you kept the pots (and perhaps glued them in place so they don't rotate). However, I desoldered mine because there wasn't space for them. Well, I've moved houses since then and have no idea where they could be. However, I know there is a way to do it without the pots, I'm just not sure how.

I found one thread on the subject here. Problem is, there are two solutions given, and I'm not sure which is right:


--- Quote from: Franco B ---There are three pins on the pot/pad. If you look at the pad as if you are holding it, bridge the bottom two pins with a 10k resistor. Attach a ground wire to the bottom pin and attach the NO terminal of the buttons microswitch to the top pin.

--- Quote from: r3ll1k ---One is to remove the potentiometer if you do the best thing to do is solder 2 10K resistors to the contacts so that they won't register as open. You then solder a wire to the middle contact as your signal wire and then wire the ground wire to any common ground on the controller.

Has anyone here done this in the past and can confirm which way is correct?

HaRuMaN:

Depends on whether you have the old pcb or the new pcb...

Ballard:

It's a gamestop-brand PCB actually.

Well, there are two versions of that one, too.  One is more complicated than the other, requiring NPN transistors along with resistors.
