Okay, so most of you have probably seen my exploits about using a mic to detect sound and either power a lone LED or connect to the inputs of a LM3915/16 bar-graph display IC. Well, i'm still taking things one step at a time, but since last year, my VU meter was attached to my laptop via cable, I was to try to branch out and send the signal wirelessly.
This is my first wireless project and I'm actually pretty happy with the results, however, I can only get a range of about a foot to two feet. I've attached the schematics for the receiver and transceiver below.
I'd like to be able to attach the outputs of the receiver to a LM3915 IC. Right now I'm lighting up a simple LED successfully, but the range stinks. It definitely won't reach the 10 feet across my dorm. How do TV remotes combat this problem??
So any comments and ideas. I really like the idea of using simple, discrete components, but I'm open to ideas. If you have any questions about parts or values, just ask. Thanks for any help you can provide. -Joe
