2.4GHz Wi-Fi Detector Ring Project

mohrt writes "The Wi-Fi detection ring was developed to give mobile computer users the ability to detect 802.11b/g signals, while providing a unique, fashionable and ultra-portable product package. The prototype circuit collects and rectifies an RF signal in the 2.4GHz range, whereafter an Atmel Tiny microprocessor, detecting the presence of a DC voltage, thusly engages a flashing LED. For those of you who have no excuse to wear a ring, well here it is."

Wouldn't cordless phones set this thing off constantly?

Silliness. Using a processor is massive overkill!

Why use a microprocessor when you can have the DC voltage from the rectified 2.4Ghz signal turn on a transistor which activates a flashing LED (or an analog flasher circuit). Surely that kind of arrangement would use much less power than running a processor (even a "tiny" one) all of the time.

Too funny... though I think you're aiming too low. Desperation is rarely attractive to a woman, and trolling for drunks and barflies is likely to be unfulfilling.

I'd suggest holding out for some quality women instead of going for the low-hanging fruit... the fruit can be sweet, but the aftertaste can be permanent. Despite the commercials you see on TV, herpes still isn't curable, and taking valtrex every day for suppressive therapy is a drag, and expensive (not to mention what happens when your next hot date goes snooping in your medicine cabinet)
