the flashlight makes it look like you broke into a hospital in the middle of the night and jacked with someone's EKG machine lol

Cool... But it now seems obvious that my scope needs to be calibrated...
Either way - I'm going to watch this till I fall asleep!

@kittykat490 Try testing things. heres something cool. get an old headphone and strip a piece of the wires. onnect one lead of your oscilloscope to one each of the wires til you get some kind of signal. try setting the volt/div to .5 and the knob on right is time. you can "see" your music.

Is that really an ossiliscope doing that or is it just special effects?

I can't do this with my DSO. It's not fast enough (only updates ~5 times a second with XY mode and is limited to about 5 kHz). :( I'm thinking of getting an analog scope just to do cool stuff like this.

you need a vectorscope, right? I'm kinda a no0b

whoa this is so freaky and cool :psyduck:
-
Aaaah... I'm a 13-year-old girl that pretty much fails at everything cool but I have an oscilloscope... The most I can do is make little dots move across the screen by turning the knobs...

@tejeez this is confusing o.0

thank you for making this
-
@Sulleric Can you teach me how to do this, please?

this is quite impressive. I've been hacking a CRT and running audio signals out of Max/MSP to achieve this effect, but haven't got anywhere near this kind of complexity.
The "low-pass filter" you're referring to is actually what is called the Nyquist frequency, and is not an effect of your player but a fundamental characteristic of digital recording. Get yourself a DAC that can play back audio at 96khz and you'll have much better results.
It actually is...
For example, a 10kHz sine wave looks like this without lpf: tinyurl . com / nhs52e . Great for drawing pixels on oscilloscope but contains lots of aliasing products (above the nyquist frequency) which should be removed with a low-pass filter. As they are outside the range of human hearing, some cheaper sound cards don't use any filters.
No way I'm doing that to my Tektronix :)
even easier: turn yourself upside down?
At least it'll look better than with isolation transformers...
