PS3 IR dongle tamed for use with a Linux box

So a man walks into a Radio Shack and the clerk says “Why the long face?”. No, that’s not it. [Ms3fgx] walks into a Radio Shack and says “holy crap, that PS3 IR dongle is only two bucks”. He’s been looking for an IR remote receiver to use with a Linux machine and decided to bend this PS3 dongle to his will. It’s a lot less expensive that the parts to build the simplest IR receivers like this FTDI cable version, or a microcontroller based receiver.

He plugged it in and was delighted to find that it enumerates. The kernel has PlayStation 3 controller support built-in and has no problem picking up this device. When he uses ‘cat’ to display the incoming data all he gets is repetitive garbage. This is because the dongle only supports Sony remote control codes. But after a bit of universal remote setup, he’s got unique commands for each button. The last piece of the puzzle is to map the controller commands to keyboard keys. This is done with the QJoyPad package, but there are a myriad of ways to remap these buttons so go with what you know.

PlayStation 3 controller made fully remappable

[Hazer] managed to take a PlayStation 3 SixAxis controller and modify it so that all of the buttons can be remapped in hardware. Aside from this being really cool, he had a good reason for doing it. Regular readers should remember the feature regarding [Chuck Bittner's] internet petition calling for button mapping as a feature in all games. As the industry still hasn’t taken up the torch in this area, [Hazer] developed this mod for [Chuck] to use and has released it for any others out there who wish to give it a try.

The hardware alterations are pretty hardcore. On the left of the image, just below the rumble motor, a DIP microcontroller is nestled dead-bug style. This is a PIC 18F14K50. It’s running a bootloader, and has its own USB port on the opposite side of the controller. By cutting traces and soldering to vias, this chip intercepts button presses and shoots them off to the controller’s processor based on alternative mapping stored in EEPROM. There’s a helper app that lets you plug the controller into a computer to specify what each button does, including features like toggle for the buttons. Check out [Chuck's] thoughts on the hardware in the video after the break.

“Extrem Konsolen Modding”

Not to be outdone by their North American counterparts, these German-speaking hackers have come up with a truly unique console mod. Although modding one system may be OK for most, the builders of this console decided to combine three systems into one clear plastic box. A stripped down Xbox360, Playstation3, and Nintendo Wii were all put together to form this “Extrem” system.

The build style should be very appealing to those interested in video game hardware. Combining the look of a tower PC with a clear plastic allows one to see all components in action. Since the box is lit up with electroluminescent lighting, one is able to show off this system in the day or at night. [Read more...]

Internal 7-segment PS3 display

[Zach] sent in his temperature controller and display for PS3, and even though it only works with a PS3 fat, we like our PS2 backwards compatibility very much, thank you.

The build stated off with [Zach] putting thermal sensors on the CPU, the RSX, and Northbridge of his PS3. After starting out controlling the fan with his laptop, he moved on to an integrated fan and display controller after seeing this post about a ‘hidden display.’ In the end, one of the coolest looking PS3 mods we’ve ever seen was born.

The build runs off an Arduino Pro that gets the temperatures from the sensors, prints everything to a custom 7-segment display board, and controls the fan. [Zach] thankfully made the Arduino source available and also put up some board files if you’d like to make your own. It’s a pretty impressive build that’s completely invisible when the PS3 is powered off.

Man spends 30 years helping disabled gamers

xbox_sip_puff

Using our hands to manipulate game controllers is something most of us take for granted. However for quadriplegics, whose arms and legs are completely paralyzed, gaming becomes a nearly impossible task. One man has spent the last 30 years of his life trying to help quadriplegics once again “pick up” the controller and enjoy a few rounds of their favorite video games.

Retired aerospace engineer [Ken Yankelevitz] has been using his skills to create game controllers that can be easily used by disabled gamers, offering them for sale at cost. Starting with Atari joysticks in 1981, he has been perfecting his craft over the years, creating some 800 mouth-operated game controllers. As the systems and their controllers became more complex, so did [Ken’s] designs. His new Xbox and Playstation controllers use all manner of components, including sip-puff tubes and lip-activated buttons in order to allow users to access every single controller function.

Even as he approaches his 70th birthday, he is busy making controllers, though at a slower pace than he has in the past. He has said that he will continue making them for as long as he can, but at some point he will have to close up shop. This has disabled gamers worried that they may no longer have someone to turn to for custom controllers, though we hope someone steps in to fill the gap whenever that day comes.

Be sure to check out his site to take a look at his designs, what he has done for the disabled community is amazing.

Fan throttling for PS3 temperature control

This setup will let you monitor Play Station 3 temperatures and throttle the cooling fan accordingly. [Killerbug666] based the project around an Arduino board, and the majority of the details about his setup are shared as comments in the sketch that he embedded in his post. He installed four thermistors in his PS3 on the CPU heatsink, the GPU heatsink, the Northbridge or Emotion Engine, and one in front of the air intake grate to measure ambient room temperature.

Above you can see the setup he used to display temperatures for each sensor on a set of 7-segment displays. The project also includes the ability to push this data over a serial connection for use with a computer or a standalone system.

The project is still in a prototyping stage. It works, but he likens the fan throttling to the sound of a car engine constantly revving. Future plans include smoothing out the fan speed corrections and scaling down the size of the hardware used in the system. We’d suggest doing away with three of the displays and adding a button that lets you select which set of sensor data you’d like to display.

Wireless controller operates your CNC mill

[Darrell Taylor] wanted to add a CNC control pendant to his mill but didn’t want to foot the bill which can often run several hundred dollars. These pendants are basically a physical remote control that operates the CNC software that controls the machine. Since he was already using a Linux box running EMC2, it wasn’t too hard to figure out how to operate the mill with a PlayStation controller.

To get the controller talking to his Linux machine he uses a package called QtsixA. The package identifies and loads the control through Bluetooth pairing. From there it can be used to map the buttons and joysticks as keys on the keyboard or as a mouse. In the video after the break [Darrell] demonstrates how he has his shortcuts set up. He’s able to move the machine head, and even start or step through the programmed routine. As he mentions, this is pretty nice if you’ve got dirty hands; just throw the controller in a zipper bag and you’re set to go.
