This is a S-Video capture of the Uzebox playing a movie @ 30fps (160x96) with 15Khz sound. Video and sound data is streamed from a standard SD/MicroSD card. Due to the fixed 256 color palette, dithering is used to enhance the overall look. Movies are converted using as mix of Photoshop batch and custom tools. Interestingly, playing the video in low quality mode will give a better picture because of the "smoothing" caused by Youtube's codec.

The Uzebox is a game console made out of only two chips (an ATmega644 and an AD725 RGB-to-NTSC converter) and a bunch of resistors. Both hardware and software are released under the GPL V3. Look at my other videos for more information on the Uzebox.

This new video introduces the Uzebox AVCore (a fully assembled commercial version) and shows off its potential with some of the latest games and demos out there! You can also buy the Fuzebox, a kit version with PCB you assemble yourself. See the project homepage for details.

The Uzebox is an open source game console based on an Atmel AVR microcontroller. The design goal was to be simple to assemble for any hobbyist and have great sound and graphics with absolute minimum hardware: an AtMega644 microcontroller, an AD725 RGB-to-NTSC converter...and a bunch of resistors!

The Uzebox is a homebrew game console made out of resistors and only two chips: an ATmega644 and an AD725 RGB-to-NTSC converter.

This video demonstrates the system kernel's four channels wavetable-based "synthesizer" and the MIDI interface that allows composition of music straight on the console.

Important disclaimer: Since I'm a lousy chiptune composer, all songs are transcriptions of 8-bit gaming classics! Hope they bring your back fond memories. :)

Everything is open source and open hardware, see the site for sources, schematics and have a look at the forums for updates (fully assembled Uzebox soon available in well know web shops!). Look for my other Uzebox videos and please rate if you liked it!

The Uzebox is a homebrew game console based on an Atmel AVR microcontroller. The design goal was to be simple to assemble for any hobbyist and have great sound and graphics with absolute minimum hardware: an AtMega644 microcontroller, an AD725 RGB-to-NTSC converter...and a bunch of resistors!

You get 256 simultaneous colors, 240x224 (40x28 tiles) graphics, a 4 channels sound engine with MIDI driver, NES joysticks ports and a MIDI IN input to compose your own songs straight on the console. The kernel is fully interrupt driven to generates video sync, mix music, read joypads, etc. so games can be written in plain C, no insane cycle counting required :D !

Considering this is an 8-bit general purpose microcontroller with only 4K of RAM and 64k of ROM (and no external RAM or frame buffer), it was quite a challenge to cram all that stuff in there. The site has the schematic and all code is open source. The hardware well...is open hardware! Have a look at the forums for updates (fully assembled Uzebox soon available in well know web shops!).

For now, I've completed a Tetris DS clone for the console.

Enjoy!
