This open-source hardware and software project shows just how much can be done with modern microcontrollers. It implements a fully functioning, NES-class programmable video game system in just a couple chips, a few resistors, and some other miscellaneous components.


This is a neat project that actually looks fairly powerful! Using only an ATmega644 microcontroller and an AD725 RGB-to-NTSC converter for major components, the Uzebox game console is a build-and-program-yourself project that is pretty simple, but also very impressive in the resulting product.

Hardware-wise, the console offers 4K of RAM and 64K of program space, with four channels of wavetable sound. Control inputs are setup for NES pads, but you could choose any similar input scheme since those old pads were just switches and not the complicated serial/analog stuff on modern commercial consoles.

The software is interrupt-driven, which prevents the programmer from having to count cycles, so its not quite as challenging to program as an Atari 2600, but should still be fun. You can access up to 256 colors thanks to the resistor-ladder DAC setup while the AD725 handles the heavy lifting to convert the signal to a standard TV-compatible NTSC signal.

Overall, it looks like you write some code that results in a very NES-class game. For example, look at the video of Tetris running on the Uzebox below and youll see that its definitely capable of NES-class games

7. SoR annoucement: microcontroller productAs many of you have realized, I have not really been happy with any of the microcontrollers available on the market. They are all missing something . . .So I am developing a microcontroller for SoR to sell (called the Axon), with revenue going to further develop/grow the SoR website. Ive done a manufacturing run and it mostly works, but Im working out the final bugs and documentation. Ive been working hard on this for the last ~6 months, and it should be ready within a month or two from now for shipment.For those who have used the Arduino, it will basically be the Arduino x 3 (in features, support, and cost). Yet it will be smaller and lighter, too.A few teaser features:16 ADCbuilt in USB3 additional UART (for camera, wireless, hyperterminal, etc)no programmer requiredcontrol up to 40 servos (building a hexapod/biped, anyone?)has a power busdesigned for the intermediate/expert builder, simple enough for a beginner  -actually, much much easier than the $50 Robot2.5"x2.5"x.7" profilefull support, easy to use software/codeRoHS compliant (environmentally friendly, no lead, etc)Price will be between $100 and $150. Send me an IM if you want to reserve one (no money down) so I can better judge how many to initially make. Those who reserve for the first produced limited batch will get ~20% off....
