    So here’s a question for those of you who know what you’re doing (unlike me). I can set this receiver up on an isolated circuit (powered by 2 AA cells), attached to a visible LED, that lights up when the TSOP goes low. Works great, and I can see it light up when I press buttons on a remote.

    The weirdness comes in when I start using my arduino uno to generate a signal (38khz + pulsed) that I will eventually drive an IR LED. But before I even attach the signal to a LED, I can get the receiver circuit to light up just by touching an exposed end of the wire hooked up the arduino’s output pin. I swear that the receiver is electrically isolated from me and the arduino completely.

    The only thing I can think of is RF. Is this TSOP really that sensitive to RF interference?

No public wish lists :(
