E-Paper IoT Door Sign PCB via Tindie Blog

I have a number of paper projects floating around in my head, but they always seemed a bit too difficult to put together. This post and video help clarify the issues in a number of ways. — Douglas

E-Paper, E Ink, or one of the several other ways to compose/capitalize this class of device is likely best-known in Amazon’s Kindle and other eBook readers. And why not? This technology is easy on the eyes, and only uses power when it changes what is displayed.

It’s such a neat concept that one would think it would be used in more projects. It does, however, have a few drawbacks like the fact that it generally doesn’t come in color, and doesn’t refresh fast enough for any sort of acceptable animation. The other important drawback from a DIY perspective is that they are relatively difficult to control. As seen in this Hackaday.io writeup, you can’t simply tell one pixel to be a certain shade of gray and expect it to work without some serious fiddling.

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.

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...
