Raspberry Pi Illuminates Staircase Steps with LEDs and a Motion Sensor via Tom's Hardware

This summer seems to be an excellent opportunity for home repair and improvement. If you're looking for something fun and colorful to spruce up your home, check out this awesome Raspberry Pi-powered LED staircase project by Reddit user chocolate_dingy.
The project concept is simple enough, it uses a motion sensor to detect when someone is walking on the stairs. There are LED strips corresponding with each step. The Pi will send a signal to light up each step depending on the location data received from the sensor.
According to the creator, the whole setup relies on a single sonar sensor. This is used to measure distance while ascending the steps. The sensor information is relayed to the Pi so it can process the location information.

Along with the busy schedules of two working parents you might have art classes, karate classes, Little League, soccer and more. Add in more than one kid and organizing your life can quickly become a nightmare. This is exactly why one of my most important organizing devices is a shared calendar that reflects all the activities and events for everyone in the household...and I do mean everything. If someone -- is required to be somewhere -- at sometime, it goes into the calendar. If we are given a calendar that reflects all the events for a particular activity (say, Little League), all these events immediately go into the calendar, along with notations on whether we are providing the team snack, working in the snack bar, etc. Even events that occur anytime during the day, like family birthdays, and other rem...

Google Docs adds templates

I have started to move away from using Microsoft Office (Word, Excel, Powerpoint, etc) in favor of online tools like Google Docs . Even as a computer consultant, I find that I use probably less than 10% of the features in any of these projects. One feature I really like in Google Docs is the easy, online file sharing that also allows you to edit simultaneously with someone else. Today, Google Docs added some templates including business cards, brochures and more. At the moment, it looks like they are rolling out this feature over time, so you might not yet see the templates on your account. When available, you will find the templates under the New... menu item. From Open Loops ... Today, Google quietly rolled out a new feature for their Google Docs Applications: Templates! It's so new that it isn't even listed on the new features page at this time. When one opens their Google Docs account and chooses to start a new document, a new "From Template..." command is pre...
