Actually.... He's not bad at tetris... he's playing a different version of tetris that has the blocks fall down when not connected to it's original piece anymore... He's making combos

worst tetris player ever
see all

Boo, Tetris has no gravity.

I LOVE THE CHIP MUSIC
NICE WORK D00D

very pretty and snowflake just rawks.

this song sounds like big blue from fzero in some parts O__O
-
incredible :)
-
Very nice!
-
Commodore SID tune :)

LOOOOOOOOOOOOOOOOOL
it's pretty nice!!11
Since 1 day i also have an oscilloscope xD
-
wow! worse player but succsessful!!! crazy world

I was shaking like an oscillograph hand watching this. Amazing)

Is this scope rewired as a vector monitor or is this all done measuring voltage? The whole thing looks amazing to me. I can't picture how you could set up a voltage pattern to make the screen. Or is this simpler than I realize?

No, the 'scope is simply in X/Y mode. No rewiring necessary.
The microcontroller simply controls the X and Y voltage pixel by pixel and scans the entire picture. But as there is no control of the beam intensity (as on a real vector screen) I use the timing for intensity. The faster the beam moves, the lesser the phosphor lights up. The timing is also such that the entire screen is drawed with 100 Hz fixed. When done drawing, you can see the beam rest in the upper left corner ;)

So it's not done by voltage levels and frequency, it's done by drawing lines between co-ordinates like any other vector monitor? I guess you are talking directly to the monitor and not plugging your output into the voltage inputs used to use the machine as a scope, right?

No, it IS done by voltage levels, channel 1 and channel 2 standard voltage inputs on the oscilloscope is all I use. When the scope is in X/Y mode (any scope can do that, no modification necessary) the voltages control the beam X and Y directly. Keep in mind this is an old analogue oscilloscope which is actually just a vector screen with extra electronics (but without intensity control). Clear?

woa! that's the first true vetorial graphics game I see.
btw, strange technique you have to play tetris =) but its effective!

Don't give me credit for inventing vector games... Take a look at old school arcade games such as Tempest and Asteroids!
