Arduino Trinket - Ocean-roaming data buoy | Hackaday via hackaday.com

An amazing free-roaming, ocean buy with tracking information. Is this something your STEAM group could put together — together? — Douglas

Put a message in a bottle and toss it in the ocean, and if you’re very lucky, years later you might get a response. Drop a floating Arduino-fied buoy into the ocean and if you’ve engineered it well, it may send data back to you for even longer.

At least that’s what [Wayne] has learned since his MDBuoyProject went live with the launching of a DIY drift buoy last year. The BOM for the buoy reads like a page from the Adafruit website: Arduino Trinket, an RTC, GPS module, Iridium satellite modem, sensors, and a solar panel. Everything lives in a clear plastic dry box along with a can of desiccant and a LiPo battery.

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...
