Phasor, high quality video

What exactly is this?

[PivotMasterD1]

I noticed that the music sounds like keygen music, and in the scene thing with all the text that lights up, one of those strings says "fairlight". Is that on purpose?

[lftkryo]

@PivotMasterD1 The "thing with all the text" is called a greetings part. That's where I greet other demo sceners and demo groups that are still active and doing awesome stuff. Keygens come from the world of software cracking, which is different from the demo scene, although they share the same roots. Fairlight has been active in both these communities for over 20 years, but even within fairlight the crackers and demo sceners are different people.

made me tap my foot

[NLRevZ]

Linus, you've done it again. Congrats on yet another awesome creation!

Did you run this at Breakpoint 2010?

(On a side note, I still have my build of your hardware chiptune project here beside me, still working :) )

Greetings from the Netherlands!

8-bit acid ¥(^.^)

[bs2290]

wow lft , this is great!

[Devicon]

Out of fucking nowhere, a parrot lol

[TheDuttyProfessor]

this is really great, love the song and the video - please don't stop doing this stuff, it's awesome!

[chaincells]

Dude. This is like LSD.

[LSLencrypted]

Awesome job, i'm using an arduino running an atmega328 - i've seen kits to convert and draw video signals. Good job! Especially the song... it's nice and feels original.

[andrei25ni]

Cool demo :)

[Arcterion]

... Whoa. 8-bit acid trip.

Pure, undiluted awesome!

[shuttershadez7]

WHO THE FUCK MISSED THE LIKE BUTTON?

[chrisiverzen]

Cool song! Is it you who have composed it?

[lftkryo]

@chrisiverzen Yes it is. Thanks!

[TheTankinTortuga]

This is EPIC WIN!!!!

[Klonkiller888]

awsum song, dude

[MrDragontamer2009]

WOW THAT WAS AWESOME

[ueberRegenbogen]

Generating video with code reminds me of the ZX-80 and ZX-81—which mustered a base horizontal resolution of 256 pixels with a 4 MHz Z-80. And since the raw video output was accessible to code, software could take over from the text-mode-only firmware to generate a 256×192×1 graphics mode (given 6k of available RAM for a frame buffer, of course).

[MrEHQE]

beautiful!

[jedor]

i think this song is not really good enough.i think u should add more loops in it.compare to mario and so on,its really not good enough~

[Primiscomputers]

Any way to mod this to work with NTSC? The signaling is a bit different, 60 hz instead of 50, color carrier is different too... oh yeah and did I mention the horizontal lines is smaller? 480i... Still any comment would be appreciated.

[lftkryo]

@Primiscomputers The biggest hurdle would be encoding the colour signal. I'm using a trick (documented on my site; follow the link in the description) to get away with generating colour information at half the nominal rate. This trick is based on the phase alteration done by PAL, and would not work for NTSC. It would still be possible to get something to work with a small subset of the available colours, though.

[ueberRegenbogen]

@lftkryo. Consider how an 8-bit Apple II induces NTSC colour. It spits out colour-burst at the start of each line, then lets the phase relationship of each pixel position determine its colour. I don't know how tightly you can generate pixels. (You'd have to go with a different clock rate to generate the lower freq sine wave of the NTSC colour-burst). The A2 gets 4 colours (incl black & white) out of a 7 MHz pixel rate, and 16 out of a 14 MHz rate, with 1-bit raw pixels.

Very very nice, love it that you went back to the 8-bit'ish sound which your earlier "controller" did not have :) Excelent composing, could listen to this all day long

[AndrewFaulds]

@thejonlord The microcontroller could have easily done an 8-bit sound, but lft chose not to program it that way.

[TheDekalibrierer]

loveable :D

lovely ♥
