Raspberry Pi Pico Spider Robot

Tom’s Hardware shares the details of robot wiz Kevin McAleer’s new Pico-powered spider robot.

This spider is still technically a work in progress but he shared lots of juicy info about its design in a recent video — plenty to indulge in. The design schematics show it’s built around a Raspberry Pi Pico but McAleer assures you could use an Arduino Nano in its place. It works by detecting people with ultrasonic sensor eyes (HC-SR04). When someone gets close, its arms wiggle open and closed. It also has LED strips inside its body that can be programmed to change colors.

Nice Pi find from Tom’s Hardware just in time for Halloween:

Poke080 shared a demo video of the Halloween eye in action. In it, we get a good look at the eye’s movement and ability to track targets. It’s illuminated from the inside with RGB LEDs to glow red, occasionally flashing green. It could theoretically be programmed to say anything but in the video, we hear a nice welcoming “Happy Halloween!”

Air Quality Monitor Project @Raspberry_Pi #PiDay #RaspberryPi

Here’s a project that brings a matteter sensor together with a Raspnerry Pi to create a DIY filtration system. Here’s more from Joyce Lin via hackster.io:

Connect a particulate matter sensor to a Raspberry Pi to trigger a DIY air filtration system. The PMS7003 particulate sensor measures the air quality and transmits data in a serial stream from the transmitter pin (TX) to the receiver pin (RX pin) on the Raspberry Pi.

See project!

“The Starry Night” Follows Laws of Physics That Weren’t Discovered Yet #ArtTuesday

VanGogh starry night ballance1 1 jpg

Science and art have always been inextricably linked. Before ‘art’ and ‘science’ were subjects in a text book scientist and artists were one and the same.

Fascinating discovery in Physics of Fluids. Van Gogh, knowingly or not, accurately depicted fluid mechanics. Laws of physics that wouldn’t be proven for decades. This depiction isn’t only on the broad strokes either: “On a microscopic scale, the scientists found that the brushstrokes and the visual effects of the paints’ viscosity also align with Batchelor’s law”

Did he know? Was it keen observation, intuition or coinidence?

Via Hyperallergic:

The research team examined the length of, space between, and varying luminance of van Gogh’s brushstrokes from each of the 14 whirling eddies in “The Starry Night,” and found that the composition intrinsically observes Richardson–Kolmogorov’s cascade picture of turbulence, specifically Kolmogorov’s −5/3 Power Law. Put simply, this predicts that turbulent flows experience energy cascades during which larger eddies transfer some of their energy into smaller ones, and that those, in turn, transfer their energy into even smaller eddies, and so on.

Early Home Computers in the work of Lola Dupre #ArtTuesday

Onc day Americans woke up to discover that home computers sat on their desks. These home computers soon brought with them the world wide web, smuggling the entire world into suburban homes from Portland, Maine to Portland, Oregon. Home computers transformed our families, our relationships, our the way we make our decisions. Nowadays we walk around with proof of that complete transformation in the form of smart phones. The work of painter Lola Dupre helps us remember just how strange home computers really are. Here’s more from COLOSSAL:

[Lola Dupre] continues her disorienting manipulations with a pair of early Apple desktops, ships with enough stories to rival a high-rise, and a cow so bloated she needs eight legs to stand. Each work pushes the limits of legibility as limbs and common objects undergo exaggerated distortions.

See Dupre’s work here!
