The micro:bit has an accelerometer and magnetometer (compass) powered by ST’s LSM303AGR chip (https://www.st.com/en/mems-and-sensors/lsm303agr.html). According to the chip’s technical specs, in terms of acceleration, you can use the micro:bit to measure acceleration up to ±16g (1g being acceleration due to gravity, i.e. 9.8 m/s2—16g is 16x acceleration due to gravity). The micro:bit uses this chip to detect gestures but it can also be used just to read acceleration in 3 axes.
In this first part, I will show a method of setting the sampling rate and plotting the accelerometer data from the micro:bit.
It’s great that the Mu Editor will allow display of the data and plot it too.
What happens when you put 1,700 of the world’s smartest teens together and ask them to show their scientific stuff?
You may get more than you bargained for.
“Science Fair,” a new documentary, follows teenagers through the highs and lows of the Intel International Science and Engineering Fair, the world’s largest pre-college science competition.
The fair, at which young people compete for millions of dollars in prizes, is a hotbed of scientific research. It’s also a hothouse of competition and teenage angst, as the documentary shows.
The film follows nine teenagers seeking to change their lives through science. Among them: Kashfia, a young Muslim who feels out of place in her large South Dakota high school and dreams of escaping small-town life through science. Robbie, a West Virginia math whiz with terrible grades, who wants to meet other kids who share his niche interests. And Anjali from Louisville, who contends with helicopter parents as she navigates the weird world of competitive science.

Violins: they’re often the first example people site when talking about traditional acoustic instruments. But using new pickup techniques and rapid prototyping, that could be about to change.
violinmakers.org is a community for this new kind of digital age luthier – a place to discuss 3D printing and magnetic pickup possibilities and electric violin fabrication, rather than gut strings and wood carving.
Community member Guy Sheffer spoke recently about why this matters. All that legacy of instrument building has perfected acoustic violins, but electric violins remain crude. As Guy writes: “The challenge is, that while modern instruments have been developing effects and new sounds, acoustic violins have been acoustic for the past 400 years.”
“We study krill so we understand whether its trends and abundance are likely to be influenced by how much fishing effort we do, but also whether that fishing effort will impact the upper trophic levels like penguins and seals,” said Christian Reiss, a senior researcher at the Southwest Fisheries Science Center in La Jolla.
But packing up a research vessel and traveling to the bottom of the world takes time and money. Both are in short supply at a federal agency that is keeping a close eye on shrinking budgets.
That is why the Teledyne G3 Slocum drone is so attractive.
The eight-foot-long submersible can carry sophisticated acoustic devices that are high-tech fish finders. The autonomous machine can identify and measure how many krill there are when it encounters a swarm.
Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
As we soak in the last rays of summer Adafruit would like to send a huge thank you to all the employees that make Adafruit what it is!
Today the team gets a day off in recognition of Labor Day. In the mantra of “Be excellent” Adafruit is always looking for ways to give workers more. We recently added a new paid day off for Election Day, and will keep looking for ways show gratitude and encouragement to the workforce!
Because of the great community and teamwork we are able to do what we do.
