Raspberry Pi Reads What It Sees, Delights Children via hack a day [Raspberry Pi]

[Geyes30]’s Raspberry Pi project does one thing: it finds arbitrary text in the camera’s view and reads it out loud. Does it do so flawlessly? Not really. Was it at least effortless to put together? Also no, but it does wonderfully illustrate the process of gluing together different bits of functionality to make something new. Also, [geyes30]’s kids find it fascinating, and that’s a win all on its own.

The device is made from a Raspberry Pi and camera and works by sending a still image from the camera to an optical character recognition (OCR) program, which converts any visible text in the image to its ASCII representation. The recognized text is then piped to the espeak engine and spoken aloud. Getting all the tools to play nicely took a bit of work, but [geyes30] documented everything so well that even a novice should be able to get the project up and running in an afternoon.

Shared calendars are one part of an organized family

by Douglas E. Welch , techiq@welchwrite.com 206-338-5832 Reader/Listener Line As a parent with a school-age child, I often hear other parents bemoaning their disorganized existence. 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...
