8-bit device quenches iphone envy
Peter deserves an award for doing more with less. He’s built a handheld device based on an AVR controller that has features normally associated with much more powerful devices. Here’s what it doesn’t do: no phone calls, no text messages, no accelerometer, and best of all no app approval needed. What it does do is leverage inexpensive, readily available components combined with common homebrew development techniques to create a touch sensitive handheld.
The demo video embedded after the break details the device playing video, rendering 3D objects, and displaying pictures and ebooks with touch scrolling. All of this is running at 60 fps for a smooth picture. The whole thing is no larger than the 320×240 LCD that he salvaged from a broken MP3 player. An Atmel AVR ATmega644 microcontroller ties together the display, a resistive touch screen, and a microSD card for storage. The chip also controls the backlight, a Lithium Polymer battery, and uses USB for PC connectivity, charging, and even a mouse or keyboard interface. He etched the PCB himself for surface mount components and managed to do it with just four jumpers needed on the underside.

Dzizaz, pa 8-bitni procesor na 12 mhz, sa 12+4 kilobajta memorije vozi ebooks i video k'o snapdragon!!! Jos da Pera nakalemi gsm sistem iz eriksona r320 i odma' ima da pazarim 50 komada!
If there's ever a time when I've matured to the point that I don't want to look at camera-phone-titties, go ahead and bury me in a shallow grave by the railroad tracks.
