The chaos game creates patterns from random dice rolls via Boing Boing

Watch a Barnsley fern and other cool patterns emerge from plotting random dice rolls on paper or onscreen. Mathematician Ben Sparks explains the chaos game with a few variants. If that's your bag, you might also like Rob's post on the related Sierpinsky triangles.

Intruder Detection Using Raspberry Pi Pico and thermal camera via Open Electronics

The home security camera does a good job, but it may not work in complete darkness. You also don’t want your gadget to trigger a false alarm if it detects, for example, a cat. In this project we will see how to build a small-scale system that just turns on an LED when it detects a person in light or dark conditions using a Raspberry Pi Pico and a thermal camera. We use Seeed Wio Terminal for the collection of data that is saved on a micro SD card integrated in the Wio terminal.

FX: a command-line JSON processing tool via Adafruit Industries

  FX is a command-line JSON data file processing tool. It can be installed via npm, brew or downloaded as a standalone binary. It can work in two modes: cli and interactive. fx comes in handy with a curl command. If you have some API which returns JSON and you want to dig into the structure or just see it, pipe JSON into fx. fx has a really neat interactive mode for digging into JSON.

Monitor water quality anywhere in the world with WaterAid via Arduino Blog

WaterAid consists of a measurement unit that senses water pH, turbidity, and temperature, as well as atmospheric temperature and humidity. Data is relayed to the system’s backend via a cellular connection, using an onboard MKR GSM 1400. Collected information from one or more devices is then displayed on a Soracom Lagoon dashboard for water monitoring from anywhere in the world! Not only can a fleet of WaterAids be used to continuously track a river, lake, or any other body of water, but individuals looking to get immediate feedback on quality can utilize the portable tool’s NeoPixel ring for color-coded judgement.

FaceTime is coming to Android and Windows via the web via The Verge

Android and Windows users will finally be able to join FaceTime calls. During its WWDC keynote, Apple announced that FaceTime is going to be available on the web so users can call in from Android devices and Windows PCs. The video calling service was previously only available on iOS and Mac devices. Apple is turning FaceTime into a bit more of a Zoom-like video calling service with this update. FaceTime is also going to allow you to grab a link to a scheduled call so that you can share it with people in advance and join in at the right time.

Google Workspace Productivity Tools Are Now Free for Everyone via iPhone Hacks

  Google started making all of its services like Docs, Sheet, Chat, and others accessible everywhere. This was limited to only Google Workspace accounts, up until now. Starting today, Google is making its Workspace productivity tools free for everyone with a Google account. The Workspace service makes it easier for you to access other Google services when you’re in another one. For example, say you’re writing a mail, and you’ve to attach a Google Sheet in the mail. What you’ll usually do is to open Google Sheet in another tab, turn on its sharing, copy the link and paste it into the mail body.

Neural Networks Emulate Any Guitar Pedal For $120 via Hackaday [Raspi]

It’s a well-established fact that a guitarist’s acumen can be accurately gauged by the size of their pedal board- the more stompboxes, the better the player. Why have one box that can do everything when you can have many that do just a few things? Jokes aside, the idea of replacing an entire pedal collection with a single box is nothing new. Your standard, old-school stompbox is an analog affair, using a combination of filters and amplifiers to achieve a certain sound. Some modern multi-effects processors use software models of older pedals to replicate their sound. These digital pedals have been around since the 90s, but none have been quite like the NeuralPi project. Just released by [GuitarML], the NeuralPi takes about $120 of hardware (including — you guessed it — a Raspberry Pi) and transforms it into the perfect pedal.

HackSpace Magazine Issue 43 – Only the Best: Mini Hot Plate Preheater via Adafruit Industries

Sometimes a soldering iron just isn’t the right tool for the job. After you learn to solder through-hole  components, you’ll often find yourself soldering surface mount components. And although you can solder them by hand, a reflow oven or hotplate is much easier and more reliable. They can be big and expensive, but not this little hotplate from Adafruit. I know a few people who have this handy little hotplate, and it works great. It’s perfect for rework, preheating, or even reflowing solder paste. Just make sure your PCB is small because it’s only 30 mm × 30 mm.
