Cool TV experement!

[Someone Electro]

I pushd a button on my tv remote while facing it in my web-cam.

You can see it flashing

At some remotes if you look at the IR LED wean pushing a button you may see a red spot flashing(in the dark uf course)


PS:
I one time wean i was trying to film a static spark i allmoust blu out my web cam! :? (thank godnes)

This is because unlike our eyes, your webcam sensor (probably cmos) is sensitive to IR wavelengths.

 

[Someone Electro]

You dont need to tell me that some cameras detect IR!

 

[windozeuser]

Sweet!

This has been a standard way of checking IR remotes for years in TV shops - simply point at a CCTV camera and look at the monitor screen.

Back in the late 70's when I was still in the service, we used several remotes together to make what we called, "a poor man's night-vision scope". It was brand-new stuff then, but still it was cheaper than the military versions. Just use a high-power remote like a flashlight while peeking through the camera eyepiece. It won't work with all camcorders, so play around with it. On a dark night, very little is more fun than sneaking up on your girlfriend's cat...

HAHAH...awesome...have to give that a try :lol:

i've also known noticed that aiming the camera at a tv allows you to see the tv screen refresh!!

The camera seems to translate the IR wavelength into visible light.

The chip in the camera is sensetive to electro-magnetic energy.Linght is just a part of the electro-magnetic spectrum!In there is infraren,gama,microwaves,radio waves...

Or for those that know more abaot electronic than science:

A camera is just a plate of mini LDR whith a lens in front(LDRs detect IR too)

 

[Sebi]

The CCD (Charge Coupled Device) in cameras not contains LDR-s....
BTW: all old camera tubes can see the IR e.g. orticon,iconoscope,plumbicon, and vidicon.

 

[Someone Electro]

Well i nont know exatly what is that chip caled.

PS:
I ment all those stuf:
LDR,Light sensitive diodes and transistors...

 

[Sebi]

LDR = Light Dependent Resistor, too slow for camera applications.

 

[Someone Electro]

I have the "TRUST SPACEC@M 350 PORTABLE"

 

[Agent 009]

Aiming the camcorder to the TV, and having the TV connected to the camcorder gives a WOW effect. Try it...

 

[Someone Electro]

I know that efect! I tryed it whith my web cam!its becose its tacing the picture of the pictute picture its tacing(this goes in a unlimited loop)

Try rotating the cam a bit!


The same thing is of you tace a miror and pace a nother one paralel whith other (same efect but much more faster)

PS:
Its cool to step in a coridor whith mirors on bouth sides!it loocks like its a unlimited room
