“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.

NEW GUIDE: DIY Turbo Button Controller #Hacks #AdafruitLearningSystem @Adafruit

the controller next to a gamepad tester. buttons are pressed along with the turbo button combo

In this project, you’ll use a Feather RP2040 USB Host to listen for a specific button combination from your attached gamepad to trigger “turbo mode” aka rapidly sending A button presses. Otherwise, the Feather acts as a passthrough for your controller, sending all of your gamepad inputs as pressed.

Raspberry Pi Pico enhances a vintage Radio Shack microcomputer kit #RaspberryPi #RadioShack @AllAboutCircuit #ShackToberFest

Don Wilcher uses a Raspberry Pi Pico to build an adjustable clock with an LED display then integrate the clock with a vintage Radio Shack Science Fair Microcomputer Trainer programmed to function as a 7-bit binary counter.

Long before the Heathkit 6800 microcomputer learning system, the Arduino Uno, or the Basic Stamp, there was Radio Shack’s Science Fair Microcomputer Trainer kit. Introduced in 1985, this easy-to-program kit was intended to teach users how microcomputers worked.

In this project article, we’ll upgrade this vintage microcomputer by building and adding an adjustable Raspberry Pi Pico clock with an LED display. After assembling the hardware, we’ll program the trainer to operate as a 7-bit binary counter. Before any of that, though, let’s spend some time learning about the trainer’s features—and, in particular, about the TMS1100 microcontroller at its core.

Don adds a Raspberry Pi Pico programmed in MicroPython, making an adjustable digital clock.

Turn Your Pi into a Wi-Fi Router

PiMyLifeUp shares how to turn your Raspberry Pi into a Wi-Fi router using Pi-Fi.

PiFi is a distribution that makes setting up your Raspberry Pi as a speedy OpenWrt-based Wi-Fi router significantly easier. It is definitely a project you will want to consider using if you want a super portable travel router.

OpenWrt, for those who do not know, is an open-source operating system with a focus on network routing. It has become a popular choice for anyone wanting to set up their very own router. PiFi utilizes its own customized version with improvements to work better on the Raspberry Pi and be controllable through their app.

Haunted House Using a Raspberry Pi #piday #raspberrypi #ElectronicHalloween

With some sensors, servos and of course a Raspberry Pi, you can create some spooky effects. Hack into store bought props to induce the ultimate chills.

NetworkChuck set up a haunted house to scare his daughters. The power of the Pi lets you set the level of scares. He goes through 1,2,3….and 4!

This is my Raspberry Pi Haunted house. In this video, I’m going to show you how to program your Raspberry Pi in Python to scare EVERYONE for Halloween. For a solid basic scare, all you’ll need is a Raspberry Pi and some speakers. For more advanced users….you’re going to have some fun.
