The JuiceBox is a personal video player that was sold by Mattel that no one cared about. It was capable of playing MP3s off of an SD card and this summer you could pick them up for low-cost as sellers disposed their stocks. [prpplague] has been hard at work creating a customized bootable rom cartridge. The MP3 adapter is a easy PC board with a SD card holder attached to it. The card is modified so the JuiceBox believes it is a video cartridge. An xD memory card is then soldered onto the back to act as storage. using the JTAG connection on the JuiceBox and a serial console you can flash the bootrom, kernel, and ram disk from the SD card onto the xD. once flashed the new customized cartridge will work on any JuiceBox. [prpplague] is still cleaning up the flash code, but it ought to be ready to go shortly.
