Open Source Ocean Data Buoy with Raspberry Pi #piday #raspberrypi @Raspberry_Pi
Here’s a project that meshes open source, 3D printing, Raspberry Pi, and coding knowhow into one yellow bobbing ocean data gathering device!
The next steps for the wave buoy project involves collecting accelerometer and gyroscope data from the onboard IMU and filtering/processing the data with a laptop to determine orientation and position. The math needed to perform these computations is too much for an arduino alone, so for now I plan to transmit the IMU data to my laptop with an Xbee and let the laptop do all the heavy lifting. Later on, the laptop will be replaced by a Raspberry Pi or other Linux based computer board, but for now it easier for me to develop everything in Matlab and then convert the code to C/C++ or something else in the future. Just personal preference.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
