    Default what kind of LEDs used in Jammers

    I know my ZR3 has LED's but does anyone know what kind of LED's they are? I would really like to understand how they work and what specifically makes them work. I am sure its not just regular old LED's. Does anyone know such things or know where a good site is for explaining how these jammers shifters are made?

    They're infrared LEDs, not a lot different from what is used in TV remote controls to transmit to the TV, but the LED's used in jammers are higher power and usually operate at a different frequency in the IR range. In the Blinder they used 870nm LEDs (not sure with the new M25/M45).

    As far as how jammers work, check out my post in this thread:

    Also, fr0st made a website with some good info:
