I've been searching for a sound activated LED circuit/schematic with little luck.
I need one that'll drive 8 high output blue LED's with the following specs:
Luminosity: 5000mcd @ 20mA
Viewing Angles: 25°
DC Forward Current: 30mA max
DC Forward Voltage: 3.3V typical
Reverse Voltage: 5V max
I've calculated I'll need an 82 ohm 5 watt resistor to drive them all. So I'll also need a pretty hefty transistor as well.
I don't want any electrical connection to my source (must use a mic), has to be non-latching and will run off of cars electrical system.
I really don't have time to bread-board at the moment, so an "out-of-the-box" answer would be great.
I've seen kits that resemble what I need, but I'd rather build it myself.
Any ideas? Please e-mail me at sparky3489@yahoo.com
