There's actually very simple composite output library - it's called TVout, it's not really something impressive with color and hires graphics, but it's made out of 2 resistors

That actually looks like it would be perfect for a disk selection overlay! If I'm reading it right, it requires one chip and two resistors.

I'd be willing to try and get some basic functionality working with that library but haven't the slightest clue how you would actually overlay it on the Atari's video signal.

I haven't used it for few months, but if I remember correctly then it was really just resistors connected to pins 11,7 and 9? There is also simple sound generator included in the library.

About overlay, I have no clue too - hope somebody here knows.

and there is a video overlay shield here: http://lowvoltagelab...ooverlayshield/

That's cool but quite expensive. I'm not sure I see an advantage to that over a $14 LCD display.

Agreed.

On a separate note, I couldn't find explicitly where all the libraries should reside. Is it under a single folder under Arduino Libraries? Which name should I use?

Thank you

That's interesting. I'd never seen video out of the arduino without another shield attached, so assumed it didn't do it. (you're not kidding with the color and resolution -- it makes a TRS-80 look luxurious.)

They're asking $60 for that! The thing about open hardware designs is that if you look around you can find something similar....

http://nootropicdesign.com/ve/

That one is $32.95. (or $24.95 for a kit if you know which end of the soldering iron to hold.)


They have another toy with video output -- http://nootropicdesign.com/hackvision/
A videogame with multiple input controller options. $43.95 assembled, or $33.95 as a kit.

That looks cool... too bad it doesn't work with the Arduino Mega

Has anybody messed with the new NetDuino boards?
