    i guess MIRTS do work. what if someone modified the usb IR posted by JackyD, http://www.usbuirt.com/overview.htm , to use more IR emitters with a higher amperage? I think this would be also be very nice to use as a IR light for nightvision cams...

    The one I saw at radio shack was square and it said 10hz on the back. Just make sure it says 10hz or 14hz. The ir filter is a option. You dont need it. But I would use one. It darkens the flash so it doesnt look obvious.

    I know people who own mirts. They are not happy and say they dont work. I dont own one. I think they are overpriced. I really dont see how they can work. The unit is very small. I dont even know how the reciever picks them up at all.

    I read the specs on usbuirt. It basicly a super remote controller.
    IR Transmission 20-60KHz

    Seeing how its not a strobe. I highly doubt it would work. Its not even the righ frequency its gotta be 10hz or 14hz.

    I know its not a strobe, but considering its connected to the computer i wonder if a program could be written to make it flash at those frequencies. The unit is very small, but what if someone attached several high outputs IR leds to the board, this might make it more feasible. Just a thought... It would be nice to have a computer controlled IR flashlight especially for those who have IR sensitive cams installed on their car.

    I just dont think leds can take the abuse. Flashing at 10hz is very fast. They are bright and are good for Police lightbars and active laser jammers etc.

    It be cool if you could get it to work! But all that work you better off. Buying a strobe and getting it to flash 10 flashes or 14 flashes a second.

    The radio shack strobe might work. Its like $30 bucks I think?

    first of all MIRTs do work... they're illegal but they work...the article from i-hacked.com describes how to build a simple adjustable flashing IR (supposably a working MIRT) ... i dont think THAT will work... the flashing sequence must be a little different than just ON/OFF/ON/OFF (at least thats what i believe) ....

    just my 2 cents

    btw. i have an idea... if digital cameras can capture Infrared Light... then how about having license plate frames that have infrared LED's around which would blank your license plate if you get flashed by red-light traffic cameras...

    Because you don't know if ALL digital cameras pick up IR.

    i have a MIRT. i threw away the cardboard box a long time ago, but it says "seven stars electronics, taiwan" on the bottom. I promise u, it does work. I saw a piece on the local news a couple years ago about them, and they said that they were going to be outlawed. So, i searched the net and bought one real quick. wish i hadnt. damn thing cost $400. now its sitting on a shelf in my laundry room. the damn thing is dangerous. im pretty much an outlaw about most things, ftp, but this thing is not a good idea. it mounts on my windshield w/ suction cups, and i was always paranoid the police were gonna see it. its supposed to be "invisible" IR, but at nite u can see a low light flashing red color. but the reason it is on my shelf is this: When u activate it, (up to 1500 ft away) your red light and the turn arrow turn green withing 3 secs, and all other lights turn red for opposing traffic. I was approaching a school one day, and turned the mirt on well b4 i got to the light. there was no traffic sitting at the light yet, but there was traffic speeding towards the red light, in front and beside me. then i noticed that the light turned green and there was a crossing guard and a whole pack of children in the middle of a large 3 lane intersection. it turned their 'walk' sign to 'dont walk' immediately and they were stuck in the middle. all the speeding traffic kept speeding and the guard was in a definite panic. i had to practically run a guy off the road and blow my horn to stop him. children were running and the guard was doing her job in the middle of the highway trying to protect them with her life. these things are not good for plain old citizens. yeah, thats the worst thing i can think of that this thing is capable of, but it can cause traffic accidents too. i will never use it again.
