Logging accelerometer data with the micro:bit

Jonathan at Impractical.ly Awesome posts about logging accelerometer data with the micro:bit

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.

Check out the blog post for more including the code.

David Lynch Is Creating a Virtual Reality Experience for Twin Peaks

via Adafruit:

Via Open Culture!

David Lynch and Mark Frost’s Black Lodge/Red Room, the extra-dimensional space that is both an integral part of Twin Peaks and iconic in its set design, is a place most of us would not want to visit. Detective Dale Cooper got trapped there for 25 years and it was not pleasant. But that hasn’t stopped fans from wanting to create that space any chance they get, whether as a bar or place to sing karaoke. And when the final episode of the second season showed the lodge was an endless series of rooms connected by hallways, it wasn’t long until the video game versions started appearing.

Well, now you can really get lost in the Black Lodge with the slow unveiling of Twin Peaks VR, which AdWeek says will be available “sometime in 2019” on Steam for HTC Vive and Oculus Rift.

This second clip gives us a bit more of the Red Room and a dubious looking Audrey Horne. The Convenience Store, however, is well done.

But this is, we stress, nowhere near a finished version. It’s not even clear if any of this will make it into the final version.

A beta version premiered two weeks ago at Lynch’s Festival of Disruption in Los Angeles. AdWeek had the only real description of the five minute demo, which starts near the ring of saplings in Glastonbury Grove:

Immediately after the pool turns to blood, viewers are transported to the Red Room, an extra-dimensional space that’s been a key feature of Twin Peaks in both the original series from the 1990s and the modern revival that aired last year. (It’s also a location frequently visited by the show’s main character, FBI Special Agent Dale Cooper.) Inside the room, viewers aren’t able to walk like they can in some VR experiences, but they’re able to teleport within the room as it rapidly changes in ways similar to what happens in the show itself. (One moment, a statue falls over before running around as a shadow on the other side of a curtain. In another, users can pick up a coffee mug that won’t empty until the second time it’s picked up.) The demo ends as a white horse appears in the room in the distance, surrounded in darkness but unreachable.

The best news is that the company developing the game, Collider Games, is giving creative control to Lynch, so hopefully the game won’t be like those terrible non-Lynch episodes in Season Two. Says AdWeek:

Science Fair shows brainy teenagers in National Geographic documentary #MakerEducation

via Adafruit:

The Washington Post reviews the new documentary Science Fair.

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.

Hacking and 3D Printing the Future of Violins #MusicMonday

 

via CDM and Adafruit:

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.”

Drones to be Utilized in Antarctic Food Web Research #drone #droneday

From KPBS:

“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.
