How to make a PS2 Guitar Hero controller out of scratch

Step 2The electronic part of it

The electronic part of it
It is really important to use a PS1 analog controller, because a PS2 controller just won't work with GH2. It doesn't matter for GH1 though, so you can make a guitar exclusively for GH1 from a PS2 pad. And so why is GH2 so picky? Beats me, but it needs a digital controller with analog sticks, and we all know that the PS2 pad is totally analog! Even the buttons, they are touch sensitive. So our only choice is a PS1 pad if we want to make it compatible with GH2 and the probable further versions (I mean beyond the Rocks the 80s, cuz' it worx the same as GH2).
I used a Typhoon 3rd party PS1 pad, because it had an ugly shape...

Ok, so here is "what goes where":

1. You have to solder the left d-pad - as if it was always pressed down - it tells the PS2 that this is a guitar controller (try to push it in the game, the tutorial menu will be unfolded).
2. GND - needed for all the switches. There are a lot of outlets of it fortunately.
3. up d-pad - strum up
4. L2 - 2 outlets for the motion sensor (star power)
5. down d-pad - strum down
6. select - I haven't found any other uses of it than star power
7. start - important for pausing the game and for the in-game menu
8. square - orange fret button (be careful, there's no little extra solder pad - but maybe yours will have)
9. R2 - green fret button
10. cross - blue fret button
11. circle - red fret button
12. triangle - yellow fret button
13. Y-axis of the left analog stick - whammy bar trimmer (connect it between GND and Ucc)
14. Ucc - the easiest place where it can be found

I won't go into details with these later, there will be a reference always in this step.

Note: I would recommend you to remove the rumble motors, because in GH they don't have a role.

Why is your circuitboard different from mine?

 Is the "Ucc"    the    "Vcc"   point  of  analog led ?

I did the same... i put the circle, square, triangle and the cross as the buttons but they don't do... i play GH2 and they don't assume to be the real buttons...

you need to solder down the left cuz thats how the game recognizes it as a guitar

Will it work with a controller looking like this? If so, give me the prints/instuctions with that, please:)

is there a way to connect a usb wire to the controller to make it compatible with the ps3?

I am not sure but i think that can´t be done But in some stores have an adapter to usb

ok one last thing... i just need to know what the original component for the the Ucc was.. like was it from the "analog" button or whatnot, if you know what i mean.. i also tried using the right analog stick for the strum bar and soldered it the same way as the whammy but it did'nt work "duh" haha but ya i just need to know where the Ucc was originally from and i'll finish the rest...
Aug 21, 2007. 11:08 AMsuper_genius says:
ya I tried that but it did'nt work it should'nt work either because it is basically a potentiometer and as far as Im concerned a potentiometer is used for adjusting something, not as a switch. and thanks about the Ucc but ya i got my strum bar working now i just used two metal strips and screwed them down next to eachother on the end facing away from eachother so i can press down to the right and up to the left. confusing much but it works so thats all i care about.
peace.

hey, haven't talked to u for a while but I had an idea that i thought i might run by you, but first I need to know if you know how what ohm the potentiometer is. Like you know how they have 10 Ohm and 100 Ohm "pots"? well I was wondering if you know what the rating is because I just cant get a strum bar to work. I've been thinking that maybe I can just put in a resistor straight on the pot(which I hope you remember from earlier, I mean the analog stick you didn't use). If you don't understand what I mean I will try to explain better, but all I need to know is what is the original ohm of the analog stick..?

oh nevermind i figured it out just forget everything i said. sorry.

ok i got a question in step 2 it says that connection 14 is Ucc ok what is Ucc??? please help tryn to put this in a real guitar
Sep 10, 2007. 5:59 PMTheMadScientist says:
in this way, couldn't you make the star power non motion activated aswell, one or both, seeing as, I dont know about you guys, but I find it annoying in a difficult spot in the song having to tilt it just so. I was thinking near the whammy bar.
