This digital picture frame runs Linux better than you might think

Ah, the beauty of spreading the guts of some hackable hardware across your workbench. This happens to be the circuit board and LCD screen from a Parrot DF3120 digital picture frame. The device is pretty powerful, considering you can still find them available for around $25. You’ll get a 3.5″ screen, ARM9 processor with 8MB or RAM, Bluetooth, a tilt sensor, and more. It seem that [BusError], [Sprite_tm], [Claude], and few others really went to town and spilled all of the secrets this device has to offer.

Their goal of the hack was to get their own Linux kernel running. It is possible to reprogram the processor using its JTAG interface. And if you really want to drill down to the good stuff, there’s access to all of the BGA pins on the bottom of the board thanks to a grid of micro vias. But the device can be tricked into flashing your own firmware just by altering a stock upgrade image.

You can get a pretty good idea of what there is to do once you’ve replaced the firmware from the video after the break. A RAM upgrade (using a chip from an old PC133 stick) lets the video run smoothly as it’s controlled via a Wii remote.

New Wii drive hardware emulation

wii_drive_emulation

The Wii-Optical-Drive-Emulator (WODE) makes it possible to load Wii and GameCube ISO files from an SD card or USB storage device. This hack uses the ribbon cable for the optical drive to connect to the Wii, requiring no soldering. The WODE is based on an ARM9 processor, runs Linux, and features a backlit LCD screen and 4-way center click joystick. Storage can be hot plugged and then an ISO selected using the stick and LCD display. Selected ISO files appear in the game channel as if an original disc had just been inserted into the drive.

The developers claim that a Wii firmware upgrade will not be able to lock out the WODE. There is also a second ribbon-cable connector to use as a pass-through, giving the option to keep the optical drive hooked up if you so desire. Now the race is on for a replacement case that can house all of this new hardware and still look nice like the original. We wouldn’t be surprised to see a homebrew channel program that allows ISO selection without having to walk over to the console.

The original report (in dutch) is a dead link so here’s the Google cache copy translated. These links came via the translated Tweakers article (here’s the original Dutch). Video after the break. Don’t pirate video games!
