hak8or is building a rover and posted pictures of DIY Bus Pirate:
Here is my bus pirate I am using for getting the contents of the EEPROM. I took the schematic from the original bus pirate, got rid of some stuff, changed some stuff, and made it a bit smaller. I should have used a SMD pic24f, but oh well. I mainly made it to break out a FT232 and practice making PCB’s and soldering. This was my first PCB I designed and soldered, and 0402 components were not THAT bad, just need a nice microscope. :P
