Rich Cook: "Programming today is a race between software engineers striving to build bigger and better idiot- proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning."

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

You should never argue with idiots because they will just drag you down to their level....then beat you with experience!

Couldn't he just generate the IR directly via DDS?

Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometres, which equates to a frequency range between approximately 1 and 430 THz.

All he needs is a faster PWM on an AVR. Better use one that has the PLL. Can't be done on a PIC, though--sorry, Leon.

Can't even get to their forums, servers are overloaded.

Using a microcontroller to set the electromagnetic radiation frequency of an LED is overkill. I suggest just using a 555 timer.

Perhaps he could use a Doppler effect to get the spectral (infra) red shift of a blue light.

No RSTDISBL, no fun!

Nice solution. I will recommend him to run with a blue LED as quick as possible :D

Might require a bit of overclocking. Probably have to hand-pick the chips to get ones that will work.

And after this,all my hopes are gone.It seems that i will never be able to turn my little blue led to an infra red one.You have broken my dreams,you are horrible and i hate you.

Ah yes, but you left out one very important detail: Does he run Towards the viewer, or Away from the viewer?

If he gets it wrong he will be even further from his goal...

Running away will be a benefit in terms of the doppler effect, but running towards will be a benefit because if you get the LED close enough then they may not be able to see it either, depending on its position relative to the person's height and the length their eyes extend from their central vertical axis. IE: If it's under the person's chin they won't see it, just as they won't see it if it's infrared.
