Title: Not specifically Amiga, but interesting.......
Post by: Firedawg on September 27, 2008, 08:56:00 PM

While seeking something on the net (parts!!!!), I came upon this project, The Uzebox Project (http://belogic.com/uzebox/index.htm), which I found to be quite interesting considering the whole project surrounds only two chips and a bunch of resistors.  I guess the most interesting aspect of this unit, and probably what keeps the project cost down is the use of an interrupt driven kernel and which has no frame buffer.  After watching a couple of supplied videos displaying the units capabilities I thought it was jam up.  For you techies out there how are they achieving this level of output on very little amount of components?

I'm not a die hard techie but it seems plausible.

Especially considering the "Commodore" joystick is on the market.

Or they have a nintendo hidden somewhere outside the picture ;-)

It's a microcontroller, it is pure magic.  See this video (http://www.youtube.com/watch?v=sNCqrylNY-0) for another similar system (with explanations).

The Uzebox project looks awsome, though.  I'm almost tempted to whip up the iron and build one myself.

Amazing...

I love this kind of stuff. Some years ago we had some free time at work and the boss told us to make some free research.

I made a Black&White 40x25 text display with a PIC. The next step was to make a color version with an ARM, but we had to start working in some big projects, and we lost this free time to play...

Of course watching this I stumbled on TRAXMOD, a MOD player using an ARM7 based microcontroller. He's also working on a PIC32 based design. Finally a MOD player in your pocket!

It is a credit to the power of the Atmel AVR core which contains lots of fore-thought to achieve a C friendly, 8-bit core with lots of peripherals that can run separately.

Basically it is an overclocked AVR microcontroller with an R2R ladder.

There is a lot more info at www.avrfreaks.net

The only issue in building one is sourcing that particular AVR as it is pretty new and in short supply.
