Everything You Need To Know About Digital Audio Signals

grinter says...

That was excellent.
I got a stairstep on an oscilloscope coming out of an analog output a while ago. Spent a few days trying to fix it, and never could. I wonder if my 'analog' oscilloscope was actually digital?

HP scanner on lead vocals: 'Somebody That I Used To Know'

spoco2 says...

Did it not annoy anyone else that the timing of that damn printer was off? It was too slow to change notes, I found it incredibly painful from that standpoint.

Also, what was actually making the notes on the oscilloscopes? We see the waveforms, but not their sources

White Trashed Knight Rider Car

..Coot looks like he wanted to get some extra mileage outta those modifications....

He's got the oscilloscope modified for hypothetical negative energy conversion..

That display in the center is so positioned to interface with the the invariance of the speed of light created by compensation for inference, and I'm only guessing here, that those buttons on the steering wheel/alignment cradle are some sort of Michelson-Morley interferometer.

Got a great deal onnit but he won't be able to keep a wormhole stable in an open perimeter....good try though, looks like someone helped their kid win a pre-school science fair!!

Camera attached to a helicopter rotor

Ariane says...

Awesome experiment. This would be a boring blur of a video except that the 60 frames a second taken by the camera matches the 60 cycles per second of the rotating blade. The sine wave distortions are the result of minute changes in the speed of the blade as it moves around.

I have seen distortion shapes like this experimenting with waves on oscilloscopes in a lab, but have never seen them mirrored in real life before.

"I haven't seen ANY flatscreens, including TFT, that show rich and accurate colors. Even with graphic designers' monitors. CRT FTW."

although You might not get the same contrast in blacks with TFT you get a crispness not possible with CRT , also majority of people viewing digital content are using TFT screens , most TFT screens also have the advantage of being 1-1 pixel mapped.

if you are doing stuff for print i still would prefer to use a TFT to work on the image due to the pixel clarity as for colours and contrast you would send out a sample/samples to the printers to make sue you are getting what you actually want back.

In short all the benofits of TFT outway CRT by far.

still love old school 70s,80s vector graphics on a CRT or oscilloscope graphics but other than that and specific artistic motivations CRT is largely redundant.

Nerdgasm: PLASMA Loudspeaker!

meow says...

If the dielectric breakdown voltage of air is 3kV/mm and the spacing between the wires is about 65mm (~2.7in), then the voltage between the wires would have to exceed 200kV before the air would ionize and allow current to flow. This would be possible with a transformer with an extremely high turns ratio at the expense of current driving ability. The oscilloscope seems to show a pulse-width modulated waveform with a low duty cycle.

Nice work with all the breadboarding! I wonder if they ran into problems with the high voltage wires arcing to something unexpected.

Clifford Stoll: 18 minutes with an agile mind

spoco2 says...

Well, geeze, a lot of negativity here. I enjoyed it thoroughly.

I too think that maybe he's a little too anti computers etc. as he's coming from the point of view of someone who grew up without them. I may as well say 'No oscilloscopes in schools' but he had them, so he can see the intrinsic value in them. (I have one in my garage).

But other than that, he speaks some truth, he jumps around a lot... but mostly, he entertained me... and one doesn't always need anything deeper than that.

Feature request: queue suggestions (Sift Talk Post)

djsunkid says...

No way- When I go on a video hunt, I keep text files of'em- a queue of videos to queue. Most of my published vids I got in probably two or three hardcore sifting sessions, where I'll watch dozens and dozens of CRAP videos to try and find each sifted one.

I don't think it would be something I'd be interested in. I'm jealous of my finds, and I think that others would agree. There is a certain level of cooperation to be found on VS, but some competition too. Farhad, for example, finds stuff (shpongle, what) that kicks my butt, but I think I've found a few that he digs too. We cooperate on some level, but we're also looking for the best vids for our own.

That leads to another interesting dichotomy. I'll be the first to admit- some of my sifts are pure "this will get lots of votes" - anything with richard dawkins, my penn&teller, etc. But then there are videos that I don't expect to even make it out of the queue, but I sift anyway- stuff that I feel is culturally significant, interesting , cool, or important for other reasons. Sometimes just videos that I find hilarious for my own reasons.
And so we have this dichotomy: On the one hand, anybody could post the daily show and get votes, but on the other, it's good to find quality content that would normally be missed.

To me, it is the mix of these elements that makes VideoSift strong- the "hot clips" that everybody on the internet has seen, along with the neglected super-cool "elite" gems that get passed over elsewhere.

So maybe you want to share your finds, but I'm keeping my hand close to my chest. They are my finds- and I'll sift them when my queue has room.
