Customize Your Google Background
Google is introducing a new feature that brings the personalization of Google a notch higher. Now, Google lets you add your favorite photo or image as the background of the Google homepage, replacing the plain white default of Google. Photos can be chosen from your computer, your own Picasa Web Album or a public gallery hosted by Picasa which includes a selection of beautiful photos.
According to Information Week, based on an e-mail from Google, customizing Google.com with a background image will not slow the search engine's load time.

Fan Control Circuit
LM56 is a monolithic thermostat designed for simple temperature control. The chip has two programmable threshold that can be used to drive a fan and or alarm. Here is the schematic diagram of the fan control circuit:
The circuit will turn on the fan when the temperature rise above 50 Celsius degree, and this threshold is set by the voltage at VT1. When the temperature rise above 70 Celsius degree then the OUT2 will go high. This signal then can be used to trigger system shutdown or just to turn on a warning LED. This threshold is set by voltage at VT2. [Schematic diagram source: National Semiconductor's Temperature Sensor Handbo...
