‘Drifting Buoy Project’ Has Been Floating and Transmitting for Nearly Two Months
Update: It’s now March 2017, so you can amend the title to *nearly eight months* – wow! Wayne writes, “the Arduino Drifting Buoy”… “is still functioning! We’re at over 220 days and about 2500 NM from where we started. Only 700 NM to Spain and Portugal. Working on a V3 for deployment this summer, also with a Trinket Pro (3V this time to save power).”
Thanks to Wayne for sending this in – him and his team built a “drifter” floating buoy that transmits data back multiple times a day including lat/long, water temp from 1′ below the surface, speed (knots), tilt angle, and more. Check out a map of the buoy’s movement here, and the full project site is here.
On Sunday 24 July 2016, after months of building and testing, we deployed a small drifting buoy 50 miles off the coast of Virginia. The buoy has a satellite transmitter and sends position and water temperature back to shore.
Here’s a quick video testing the buoy including an intentional upside-down drop to see how the buoy rights itself:
And the deployment video from July 24th, about 50 miles offshore east of Virginia Beach in the Atlantic Ocean:
Adafruit Pro Trinket – 5V 16MHz: Trinket’s got a big sister in town – the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious. Read more.
Adafruit DS3231 Precision RTC Breakout: The datasheet for the DS3231 explains that this part is an “Extremely Accurate I²C-Integrated RTC/TCXO/Crystal”. And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low power package. Read more.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
