Show and tell, Arduino oscilloscope.

A few days ago i found the arduino oscilloscope on the web. I decided to make one with some stuff i had laying around. Few resistors, diodes, a composite display from an old car d vd-player. And an arduino...

It uses the "tv_out" library available on github, and a premade sketch wich is available from here http://arduino.cc/forum/index.php?topic=64327.0 (not made by me)

It works up to 160 khz and has 2 buttons for scaling and pitch

For now it is only one way (DC) voltages. So with a sinus, only the upper half will show. Of someone knows how to make this work both ways, any help is welcome.

Anyway, let me know what you think!
