Cheap 360 Degree Head Tracking


[Joel] sent in his efforts to build an inexpensive 360 degree head tracking display. He’s using a Playstation six axis controller as the key to his helmet tracking system. The demo is short and to the point. He’s using the usual Glovepie driver to provide the software interface and what looks like off the shelf hardware on the helmet.

What really grabs my attention is the low cost of getting into VR now. Assuming that you own a computer, you can build your own VR setup for the cost of a Playstation controller and a cheap heads up display. (Remember these?)

PSP Internal Hard Drive Mod


[Robin] over at acidmods sent in this interesting PSP mod. [PvP] added an internal hard drive (with the exception of a mini-usb cable sticking out the top) to his PSP. The advantage? Laptop hard drives are dirt cheap while sony memory sticks are still pretty pricy. More details should be along soon, but [Robin] assures me that this means up to 200GB of storage is possible for the PSP.

Obfuscate Your Power Switch


Just in time to keep your friends from sharing your toys, [l0rdnic0] brings you this simple mod: replace your power switch with a reed switch. Of course, now you’ll need a magnet every time you want to use your PSP. Of course, if my older brother did this, I’d build a big electromagnet and start firing it whenever he started playing games.

Pandora’s Battery (unbrick Your PSP)


[krazywhiteguy310] let me know about the announcement of the Pandora battery hack. It’ll cost you a Sony PSP battery to pull off the hack, but once you’re done, you can use it to jump start your bricked PSP to load up a memory imaged designed to unbrick the PSP. (I haven’t tested it, so I’m taking this on faith) Excellent news if you’ve bricked your PSP.

Force Feedback PSP Mod


[F00 f00] sent in his latest PSP mod. By combining a voltage amplifier, a PIC controller and a cell phone motor he ended up with force feedback enabled PSP. He’s got the PIC set to enable the motor when it detects certain sound frequencies from the speaker via the amp.

The video is after the break.

Virtualcogs Open Portable Gaming Platform


[David] thought you guys might like this – and I agree. It’s an open gaming platform built around a PSP LCD. It’s got all the basics, and it’s expandable. They’d like to put together an order for a run of boards, so let em know if you want one. If you’re lazy, here’s the specs:

  • MX21 ARM9 266MHz processor with 64MB SDRAM and 16 MB of FLASH
  • TFT LCD from the PSP (our thanks to Nathan at Sparkfun for helping us out with that)
  • stereo audio CODEC
  • stereo speakers
  • headphone jack
  • microphone
  • couple of joysticks
  • loads of buttons
  • battery pack
  • SD/MMC slot
  • expandable (can add GPS, bluetooth, accelerometers and gyros, etc…)

Most of the hardware is pretty decent, but the battery pack could use some help. Maybe a good surplus li-ion cell phone battery.
