building my own IR receiver ...

I also have an extra Hauppauge receiver (but it plugs in a Hauppauge mini jack), can I use the IR receiver IC component? I am trying to waste as little money as possible ;)

If your serial port spits out high enough voltage, you should be able to use the 7805 that Radio Shack sells: 276-1770.
The 78L05 is much smaller (TO-92, the size of the transistors you've been buying). The 7805 may not be very efficient, but it shouldn't matter too much. If your serial port doesn't spit out enough voltage, the 7805 may not deliver 5 volts.

If you want, I can toss a 78L05 in the mail. If I can find them, I should have 100 or so around here.
work is done in a microntroller, offboard from the PC.
Smee, the last url in my first post shows how the guy tried using the one from RS, but it didn't work, do you think he got the 78L05? I think I might take you up on your offer if you can find that pile of 7805's ;)

So why would anyone want to use the Ocelot IR input at all then? Am I missing something?
My understanding (now) is that it's primarily used to record an IR sequence which will be played back. The goal is to have the Ocelot control other devices, not really for it to be controlled.
 
That's what I am saying, why would you want to buy one of these IR receiver dongles if all you use it for is to learn IR sequences?
 
Well, one reason is that the Ocelot is sometimes mounted in a hidden location (hence its case shape with mounting tabs) so using the built-in receiver would be difficult or inpossible. Then there is the added possibility of using it to receive an IR command and act upon it. Its too slow for real time control but to trigger a macro it might be ok.

Compared to a Pronto, the Pronto also has an IR receiver for learning but I don't think that it offers the added capability to receive an IR command from another remote to then trigger a macro of output commands...the Ocelot at least gives you that extra., although its not perfect.
 
I tried the macro triggering thing, and even then it dropped some of the IR commands. I understand the Ocelot wasn't designed to do this, I just wanted to make sure I wasn't doing something wrong. Back to my IR receiver ;)
 
When you learn an IR code for the purpose of recognizing it later to trigger an action, it is best to hold the remote's button down for a full second in order to fill out the entire sampling window. This makes pattern matching more consistant. Give it another try...
 
As far as using the Ocelot, just for clarification, are you trying to blast it at the IR receiver or are you going into the IR Aux Input? If you're using the Aux IR Input port, you must use the IR Receiver cable from ADI. This cable has circuitry inside that strips off the carrier portion of the signal and injects the IR code directly. The cable runs about $10.00. The Ocelot should be able to be used as an IR receiver, but it has to learn the codes first before they will be passed through.
