made this and wrote the signal processing routine. works surprisingly well. seems to perform better in warm rooms. you can view the finished project here:
What I like in this video is that there is no amp and your transmitter/receiver generates pretty strong signal. Can you tell, what number analogRead() returns? I used crappy transmitter/receiver that gave about 50 at maximum. What element do you use?

Hi, would you be so kind as to share the schematics for your set up? Can't really see it from the video, especially the value of the resistors used. Thanks in advance!
