PS3 controller modification

Hello All,

Its been so long since i dropped some thing on here, but here is what i've been working on:








Here it is! A modification of the playstation controlled. I'm no good at reverse engineering hardware, so the plan is to make use of the stuff there and install my own. Eventually I'll use this as a media remote.


This is the joy stick section of it, basically it functions as a voltage divider, 5v one side ground the other, read the value in the middle. All the buttons function as pull down switches, that is when the button is closed the corresponding pin is pulled to 0v from 5v

Above is testing the set up on the breadboard before everything goes in. The system works by reading the values of all the pins through a de multiplexer, reducing the number of pins required by the arduino to read the button that has been pressed. the down side to the method is that two buttons press at the same time can't be distinguished. But the purpose i'm thinking (media remote) that won't be an issue.


The battery was a little too big, one way to fix that.
Throw everything in the mix, on the right hand side i will put a bluetooth module that will allow the system to communicate with the outside world.The mini arduinos are pretty small, fits nicely into the stem of the controller.

PWM, MSQEQ7, Arduino ProMini, Its got everything

Hey guys, thought i'd share a few images of what i've been working on.
Using:
  • Arduino ProMini
  • msgeq7 sound equalizer 
  • 12v led strips attached to pwm outputs
  • few transistors
  • Etching kit
I managed to whip up some case lighting for my computer, its not perfect yet but its on the way.
The idea was to pass the sound through the equaliser and have the lights react to the sound, that still needs a little fiddling, but since the arduino is there i can interface with the lights and do some fun things.
Most of the project was new to me, using transistors (i burnt a few) and etching.
That's the schematic that i'm building from. points to who ever can pick out the problems. I'll leave the 2 that i know of at the end of this post.


I'll let the images do the talking.

Thats my initial power supply, fairly dodgy
This is me learning the ins and outs of transistors, and testing the setup with the uno

This is the sketch after is has been ironed onto the board


The final check before etching


Soldering just started, the beginning of more problems...



Faults in the board

Look at this image full size, the trace just above the power pin has a crack in it, took me a while to find! The use of the multimeter to do a continuity check worked a treat.(this picture as taken through a magnifying glass so its fairly small)

O'course here is the current copy of the files that are on the sketch,
This is all running on the arduino ProMini, which i don't have a picture of :(
I ended up programing the mini via the uno, which worked alright, not the best but good enough

If you want to know more, leave a comment. (ill edit this soon with some some final pictures.

Problems with the schematic
  • Ground of power supply not connected to anything
  • No pull down resistor on the push button
I should add, feel free to use for personal projects, would love some return kudos if you do use it, makes me feel good.
If you want to make and sell anything, please don't without seeking permission for the rights to do so from me.

Eagle Schematic for LED CASE Lighting, With MSGEQ7 Sound equaliser

Might have to click to see it easier,
Its gonna end up on a PCB, im working on that part
transistors, worked them out, lets hope they work with some fast switching

12v power supply

who needs desktop power supply when you can pull you computer up close and use one of the molex connections? I justify this because the end result will be powered off the molex power.

At the start of a new project! It will be a pwm sound controlled thing for the computer case. more to come.

Files down

some of the files are down, i'll have them fixed up in a week or so.
The new files shall have a few updates
Files are back online
