Welcome to the weekend: Please turn off your computers at the end of the day, enjoy the weather (whatever the temperature), and return to your full, upright positions on Monday. In the meantime:
The Wi-Fi is strong in this one: Make a Wi-Fi sensor that puts a signal heartbeat in your pocket (via BoingBoing).
Wi-Fi stays in with this paint: EM-SEC Technologies will sell a coating costing $4 to $5 per square foot (in small quantities) that can block electromagnetic transmission to create secure rooms in buildings. I'll be curious if people who have self-identified as electrosensitive will use this paint to keep signals out?
