Composite is not much different but progressive video have an advantage over the interlaced composite video,
being it, well,…progressive! It is not composite that makes it a bit more complex.
Ali, for now I consider the project closed, but how about considering my project a starting point for the composite
version of your own ? In case, I’d be happy to link to your project.

Best regards and thank you very much for your appreciation

This is a very nice work! but i’m fairly “noob-ish” so bear with me, i understand that vga is reasonably simple compared to composite, but how pratical would it be to make the ATtiny48 output in a composite compatible form? i’ve seen a few things around about a monochrome composite output from an atmel chip, and it seems pratical.

Caio Joaquim,
I typically use an old limited functions demo of Orcad for drawing the parts of the schematics, then the pieces are exported (within Orcad) in DXF vector format. DXFs are then imported in Illustrator, which I have occasionally access to, to be glued together and sort of beautified.
Ciao e grazie

Best regards
A.

I wonder what software you use to draw the schematics ?

[...] This small circuit is very simple to make,with only few components caps, resistors and the heart of this circuit is Attiny84 microcontroller running at 20MHz. Source: 5volt [...]

very nice work. the paper mask over the perfboard is an exceptional idea – i’ll remember that. I wonder if they’d stand up to my soldering though!
