Behold, the homemade mini-tablet
Jose, otherwise known as gpeiro06 to fellow members of the Todopic programming forums, is an unusual man in the best possible way. Instead of going out and purchasing a shiny new PDA from the store, he went ahead and skipped the usual retail cycle by just building his own.
Actually, he did something cooler than just make a run-of-a-mill PDA. His homebrew device apparently has the potential to be used as a game console, an oscilloscope, a clock, and a wristwatch. The possibilities, though not endless, are certainly huge.
At the core of jgpiero06's homemade PDA lies a 170MHz ARM Cortex-M4 processor. As for the motherboard, it's got a hodgepodge of electronic parts that include an SD Card slot, a USB port (which is currently only used for charging the battery), and a touchscreen LCD controller.
After trying out various programming libraries, jgpiero06 settled on GWEN, a highly adaptable, lightweight library made in C++. See the original thread (English translation) for full technical details.
Like the people at Hack A Day, I'm kind of stoked over the thought of what might follow in the not-so-distant future. Right now, jgpiero06's PDA isn't capable of much just yet, but projects like his make me hopeful that the homebrew community might one day be able to compete with the big dogs at their own game.
