Kofi,
you might have that backwards.

There was a statue in the Film Institute in Brussels that I saw in 1970, dedicated, supposedly, to the guy... the idiot... who proved that staring at the sun can make you go blind. I just tried to find out who this is, and ran across a great article at [Link: mintaka.sdsu.edu]. From near the end of this article:

When the sun is low in the sky it is yellow or orange indicating that the hazardous blue light has been scattered out of the direct path of sunlight, and the sun may be fixated for many minutes without risk.

This implies that it's not the colors beyond red that cause damage, but the colors beyond blue. Anecdotal proof can be found in sunblocks never being IR rated, but UV rated, and products made to be in the sun rated for their ability to withstand UV, never IR.


By the way --

Doesnt work very well anymore. Worked great with my motorazr.

For a lowtech solution that predates the cell phone camera...

I printed this out and it did not work. What gives?
A good answer is easier with a clear question giving the make and model of everything.

Have you ever taken your camera / phone and pointed at an IR Cam (night vision cam) at night? You see all the illuminators on it. Also cool if you have two IR PTZ cams that you can maneuver over to "look" at each other in the dark.

Another trick, less impressive but it work fine also: Get a good old am/fm radio, tune AM 1400 and press the buttons of the remote while the IR emitter is very close to the antenna. You will hear it.

No way! Really?

Heh, it's old but I guess you guys never saw this [Link: remotecentral.com]

Also URC at a trade show was giving away the "bIRd" - a bright yellow remote with no buttons whose only function is to chirp when it senses IR. Technically it's for detecting problem IR sources such as LCDs, plasmas and lighting that can conflict with remotes, but of course it'll also detect remotes...

Did you subject the test card to light for 1 minute?

I used to that, with video cameras back in my BB days (1995) to test remotes people brought it.

Another trick to try when you have a non-working manufacturer remote is put the batteries in backwards, press as many buttons as you can. Put the batteries back in correctly and that sometime brings back a remote.

yup, real old trick ( wow Dan, that link brought back some memories, do you still have the blanket you used to test remotes)

I am not sure of the physics, but it is not really a CCD thing, like KVH kind of pointed out, you could do it with old none digital camcorders as well (like those big VHS monstrosities).
