First off if you don't like this then don't read it. If your only going to complain its not CFW or QA flag then go away.

If you can't be asked to read just watch the video

Now i have said that, this is my PS3 case mod, there are 4 seven segment displays on the front. The left two show the temperature of the PS3 from a LM35dt temperature sensor i have added between the two heat-sinks on the motherboard. The two displays on the right show the current fans speed as a percent. The fan speed will go up as the temperature goes up, or you can set the fan speed manually with my TV remote. The display can be turned on or off with the remote, also you can make it count down from 99 to 0 in 1 second (i got bored so i added this, there is not practical reason).
I have also added a blue PlayStation logo on the top of the front of the PS3, as well as some red LEDs shining out of the air vents on the top and the front of the PS3. These LEDs have three modes, ON, OFF, and sound reactive. They will flash to whatever sound is coming out of the PS3. Of course these modes are selected from the remote.

I have taken lots of pictures as i went along of the wiring and of the holes so if you are interested have a look:
For the full Album click here


The left number is the temperature and the right one is fan speed (42c & 44%)



The right board is the 4 MCP23008 chips controlling the 7 segment displays. The left board is full of transistors that control the 12v current to the LEDs. The 5v voltage regulator is on the bottom of the left board.



This is the LEDs before they were wired

If you are wondering this is not a copy or a mod of KillerBug's mod, i have been working on a similar project. However i still want to say a big thanks to him as he has answered lots of questions i have asked him as well as recommending me the MCP23008 chips.

If you have any suggestions or comments then please post or PM me

[KingKush]

Wow I am totally impressed man, That is 1 super killer mod, that is sick!!!

[Chris9191]

that is really good. ime going to try this myslef. with your help lol

[KillerBug]

That is some great stuff...simply awesome; this needs to be front page'd.

A few questions...
-Using the automatic control where 1 degree = 1% fan speed, how hot does it get while gaming?
-I don't see the music reaction in the code...are you using an off-the-shelf unit or am I just tired and missing that section?
-What hardware are you using for the IR, and where did you put the sensor?

[daveyp187]

dude that is awesome

are you selling it...

1) This PS3 has a broken blu-ray drive so i can't test a game like COD, I have not tested playing a PSN game yet but it seems to settle at 48 and it is a very smooth speed change, not like your "revving" . (ill edit this after more testing)
EDIT:
Ok its been on over an hour now and i've tried a few different games and the temperature peaked at 51 and settled at 50 while playing, i'm sure it would go higher playing COD. The most demanding game i have on it is Burn Zombie Burn.

2) The music reaction is done with 2 TIP31a transistors. The sound from the motherboard is connected to the base of the first transistor. That transistor has 5v going through the collector - emmitor. the emmitor of the first transistor is connected to the base of the second. The second then has 12v going from collector to emmitor. The LEDs are connected to the collector leg and the emmitor is grounded.
There is a third transistor used as a switch which the arduino controls to put the LEDs into reactive mode.
Hope you can follow that, ill try again if not.

3) You are asking about the hardware, not the libraries. OK. I used a TSOP4838 Infrared Reciever 38kHz. Since i snapped of almost all the pins on the translucent case of the ps3 i put the reviver in one of the holes on top of the blu-ray drive. It still get good signal across the room through the lid.

That is really cool

Neat...btw; mine hasn't revved since the first release. I'll have to pickup one of those IR receivers...seeing this gives me some interesting ideas; I never even thought of putting stuff behind that panel.

Zembor0, just an idea, but i think your PS3 should react to sounds too. Like Playstation, on. Playstation, off. And then maybe Playstation Disc Off or what ever you think is good for it. Anyways it's amazing piece of work and art
