Weaving just got a lot better thanks to this Arduino-controlled Jacquard loom via Arduino Blog

Jacquard looms revolutionized the weaving process by independently controlling each heddle’s position. That made it possible to weave complex patterns. But modern Jacquard looms are very expensive, because they require a solenoid or other means of actuation for each and every heddle. Lea Albaugh and her team at Carnegie Mellon University found an affordable way to build a Jacquard loom from 3D printer parts — including an Arduino-based controller.

The key development for this Jacquard loom was a special bistable switch for each heddle. Those switches keep their heddles in the position in which they were last set. That makes it possible to set the heddle positions sequentially, instead of simultaneously with a multitude of solenoids. All of the heddle positions can be set by a single solenoid, which slides back and forth across the loom. This keeps costs down and makes it possible to build a Jacquard loom for about $200 using common 3D printer components.

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...
