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."
More visible then the cook ring. The wifi ring gives your average joe six pack the ability to pick out teh ghey with little or no effort.
