2 questions...

Is it compatabile with my tin foil hat?

How can you tell if it's on?

if you have access to security cameras, try pointing a TV remote at it and pushing some buttons - you should be able to see it :) this works with many color ones too, but not quite as well.

Thought I replied earlier.

You tell it's on by either:
a) looking at it with an appropriate camera or filter, or
b) adding a regular (eg red) LED into the mix and trusting that the others are working

Of course this sort of thing could be installed around the brim of a hat, or in clothes, or whatnot.

And Junkie's right, which is why this works on very little battery power for a very long time.

I wonder how long it'll be 'till we start seeing it as part of the latest gas-station-robbing bling? Somehow I doubt the homies would go for the geekery of it, but it'd be good for business...

I wonder how many will walk into a well lit place thinking it'll blind the cameras.

[saizai]

Charles - It actually should work in a well lit place if the camera is one of the standard types that's sensitive to IR. (LED IR power - background IR illumination)*camera sensitivity is bigger than you might think.

Of course, as soon as people start using these in robberies, security cameras will start sporting IR filters.

One hopes.

My guess is it'll take a few high-profile news cases (like say, someone gets shot and they have no evidence because the person blinded the cameras). :rolleyes

Compare to bump keys - it's only barely gotten any press in the US, nearly all locks sold here are vulnerable (including the otherwise high-quality ones), and nobody's going to give a shit until some idiot gets caught on tape using one in a major case.

Whereas in Europe, it's gotten plenty of press, and they are already rolling out anti-bump locks.

Nice. I should use or build one for the next time I'm out urban exploring. To see if it's on, put a video camera on night shot and take a look from a distance.

IR Spotlights are pretty cool too. It will light up an area that can't be seen with the naked eye but point a camera equipped with night shot and viola! (not the instrument).

I was just thinking that as the backgound illumination increases, the "iris" of the camera will adjust and become less sensitive to the glare. Kind of like taking a flash pic during the day with a reflector. The reflector is bright, but everything else is still visible. take the same pic at night and all you'll see is the reflector.
