PS3 Sixaxis controller now houses exploit

[Hasuky] posted a guide for turning a PlayStation 3 Sixaxis controller into a PSGroove exploit device (translated). Unfortunately you’ve got to crack open the controller and add some parts to get it working. The hack requires a PIC 18F2550 (a chip we’ve already seen used as a standalone PSGroove device), a crystal, and various resistors and capacitors to connect to the controller’s PCB. From there you connect the USB cable between the controller and the game console and boot using the exploit.

PSGroove on a PIC microcontroller

There’s now a method of using PIC microcontrollers to exploit the PlayStation 3. This is centered around a PIC 18F2550 which has been popular in past hacks because of its built-in USB serial port. This again makes use of the PSGroove open source exploit code and, like the TI calculator version, seeks to expand the selection of hardware the code runs on.

In addition to the chip and a PIC programmer you’ll need the CCS compiler as others cannot successfully compile this code. A licensed copy is necessary because the demo version of the CCS compiler doesn’t support this particular chip. Add to that the fact that because of the timing it may take several tries to achieve the exploit and you may find yourself disappointed by this development. But there’s always room for improvement and this is a proven first step on the new architecture.

Car computer requires PIN for ignition

[Ben’s] added some nice goodies to his Volvo in the form of an in-dash computer. The system monitors two pressure sensors for boost and vacuum, as well as reading RPM, O2, and exhaust directly. All of this is tied into the touch interface running on an eeePC 900A. But our favorite feature is that the system requires you to enter a PIN to start the ignition. The forum post linked above is short on details so we asked [Ben] if he could tell us more. Join us after the break for a demonstration video as well as [Ben’s] rundown on the system.

RGB VU meter

[Simon Inns] turned out this VU meter with a 16 RGB LEDs. He’s using three 16-bit TLC5940NTG LED drivers for the project. They’re not cheap chips but they do a great job. If you were looking to save on parts [Simon] found there’s more than enough brightness and any loss due to multiplexing would not be a problem. The device connects to a computer via USB thanks to the PIC 18F2550 which he’s used in his past VU meter projects. One of the design choices he made was to use a switching power supply. The LM2576 (datasheet) has no problem sourcing 3A at 5V and in addition to two electrolytic capacitors which are commonly used with linear regulators, you just need to add a diode and an inductor.

The meter offers several different configurations which are set on the PC side of things. These include the colors that are used and if the entire bars is used as one meter or split into sections to display both audio channels. Check it out after the break.

The UltimateSIMON

[Simon Inns] designed a circuit board to retrofit an original Simon electronic game. This hack is immediately a win because he made sure that his design required no modification of the original case. The new PCB has many improvements. It moves the device from using 2 D-cells over to a 9 volt battery, the incandescent bulbs were out swapped out for three LEDs per button, and the use of tactile switches makes the buttons a lot more responsive (but does require a bit of modification to the colored button covers). Under the hood there’s a PIC18F2550 controlling a serial LED chip and handling input monitoring and sound generation. The video after the break is safe to watch at work, there’s no swearing involved this time. Continue reading “The UltimateSIMON”
