Digital picture frame reverse engineering

A few months ago [Jason] got his hands on a free Coby DP700WD digital picture frame and thought it would be fun to hack. After realizing that the frame did not run any sort of Linux-based OS he figured his options were pretty limited, but he gave it a shot anyways.

The frame came with a set of built in images, and his goal was to swap them out for pictures of his own. He started by trying to read data from the frame’s serial flash chip, but found that the processor was preventing him from doing so. He de-soldered the chip from the frame, mounted it on a makeshift breakout board, and started reading up on SPI.

He was eventually able to read the device’s flash chip and swapped out the built-in images with his own. After a bit of trial and error, he was able to replace the frame’s boot screen with his own custom image as well.

If you are looking to do something similar, be sure to swing by his site – all of the tools and code he used to hack his frame are available for the taking.

Hacking a digital picture keychain

coby

The Coby DP-151sx Digital picture frame keychain seems to be ripe for hacking. At roughly $9, you get a screen, and Li-Ion battery. That’s not bad considering a similar screen alone would cost $20 elsewhere even though it runs on a slower serial connection.  While they’ve only put a 3 color pattern on it so far, more can’t be far behind. If you don’t feel like actually tearing it apart, there are some projects that have managed to customize what it displays via the USB connection.
