    Is it good or bad that they are close?

    Some audio recording softwares can actually record at 38khz. Would this be better ?

    Because you're sampling at specific time intervals, and the sampling is the same as the incoming carrier frequency, you might sample a LOW every time - you should sample a MINIMUM of 2.5 times the maximum frequency.

    Hey im new here, sounds like a cool idea. Just a quick question for ya. Dont some IR photodiodes only respond to certain wavelengths eg. 900nm? So what if the IR LED sends out a different wavelength to what the photo diode in an appliance can pick up? Does it matter too much if the wavelengths are different?

    It makes hardly any difference, pretty well all IR remotes use similar wavelength diodes.

    Has anyone actually made their own Griffin IR module yet? I don't mean to be a noob asking for schematics, but I 've tried a few times without luck. The only solution I see is using an amplifier to actually drive the LEDs.

    i think the qwestion was post a circuit...
    i would like one too...
    even a note on a napkin will do (i hope i dont regret that...)
    thanx in advanced

    what is a restor? I couldn't find its definition from hyperdictionary.com..
    Something to ask about the 3.5mm jack.
    As i know, there are 3 terminals at the jack, can i know which one represent what?

    Analog audio has a stadard of 2V +/- output.So you need a resistor that will let trough about 20mA whith a aproximete half volt drop. Ohoms law says 25Ohm a comon resistor is 22Ohm so use that.

    Google wil find you audio jack pinouts.And wikipedia wil give you lots of info about resistors and IR LEDs.

    do you have a circuit for the sound to IR converter? and the Phototransistor circuit needed to input the IR signals to the PC.

    Thank You

    Circuit Diagram

    tried makin the transmitter, with that LED and the 220ohm resister, used a common audio jack. the thing is how do i make that phototransistor circuit for the input of the signal> ?
