Using Homebrew Coils To Measure Mains Current, And Taking The Circuit Breaker Challenge
https://hackaday.com/2021/09/12/using-homebrew-coils-measure-mains-current-and-taking-the-circuit-breaker-challenge/
Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current flowing in the wires of his house, he did what any of us would do: he built his own current sensing system.

It is easy to apply computers to improve things we already understand. For example, instead of a piano today, you might buy a synthesizer. It looks and works — sometimes — as a piano. But it can also do lots of other things like play horns, or accompany you with a rhythm track or record and playback your music. There’s plenty of examples of this: word processors instead of typewriters, MP3 players instead of tape decks, and PDF files instead of printed material. But what about something totally new? I was thinking of this while looking at Sonic Pi, a musical instrument you play by coding.

COVID Green Pass Validator With Raspberry Pi
https://hackaday.com/2021/09/25/covid-green-pass-validator-with-raspberry-pi/
It seems like every nation is dealing with the plague a little differently. In June, the EU instated a COVID Green Pass which comes in the form of a paper or digital QR code. It was designed to grease the wheels of travel throughout Europe and allow access to nursing homes. As of early August, the Green Pass is now required of those 12 and older in Italy to gain access to bars and restaurants, museums, theaters, etc. — anywhere people gather in sizeable groups. The Green Pass shows that you’ve either been vaccinated, have had COVID and recovered, or you have tested negative, and there are different half-lives for each condition: nine months for vaccinated, six for recovered, and just forty-eight hours for a negative test.
[Luca Dentella] has built a Green Pass validator using a Raspberry Pi and a Raspi camera. Actual validation must be done through the official app, so this project is merely for educational purposes. Here’s how it works: the user data including their status and the date/time of pass issuance are encoded into a JSON file, then into CBOR, then it is digitally signed for authenticity. After that, the information is zipped up into a base-45 string, which gets represented as a QR code on your phone. Fortunately, [Luca] found the Minister of Health’s GitHub, which does the hard work of re-inflating the JSON object.
Let’s learn together: Raspberry Pi and Green Pass

Raspberry Pi Plots World Wide Earthquakes
https://hackaday.com/2021/10/05/raspberry-pi-plots-world-wide-earthquakes/
What do you do when you stumble across a website posting real-time earthquake data? Well, if you’re [Craig Lindley] you write some code to format it nicely onto a display, put it in a box, and watch it whilst making dinner.
[Craig] started off with coding in Forth on the ESP32, using ESP32Forth, but admits it didn’t go so well, ditching the ESP32 for a Raspberry Pi 3 he had lying around, and after a brief detour via C++, he settled on a Python implementation using Pygame.

SparkFun Offers 60GHz Pulsed Coherent Radar with Latest Raspberry Pi Add-on Board
https://www.hackster.io/news/sparkfun-offers-60ghz-pulsed-coherent-radar-with-latest-raspberry-pi-add-on-board-9b6c78314a22
Communicating over SPI at up to 50MHz, this board makes it easy to get highly-accurate positioning data — on ARMv7 or Cortex-M4, at least.
SparkFun has launched a new revision of its break-out board for the Acconeer A111 60GHz pulsed coherent radar (PCR) chip — and it’s designed for easy mounting on the top of a Raspberry Pi or compatible single-board computer.
“Does your project require high-precision, cutting-edge distance measurement? Or maybe speed, motion, or gesture-sensing,” SparkFun writes of its latest launch. “We’re not talking about simple ultrasonic or even infrared here, but 60GHz radar! Well say hello to the SparkFun A111 Pulsed Radar Breakout.”

Raspberry Pi’s New Build HAT Adds LEGO Technic, SPIKE Compatibility via an RP2040 Microcontroller
https://www.hackster.io/news/raspberry-pi-s-new-build-hat-adds-lego-technic-spike-compatibility-via-an-rp2040-microcontroller-95516afc6101
Driving up to four motors and/or sensors, this partnership between Raspberry Pi and LEGO Education is a smart move.
Raspberry Pi has announced the launch of its second RP2040-powered microcontroller board, and this one aims to bridge the worlds of Raspberry Pi and LEGO Technic: the Raspberry Pi Build HAT.
Designed in partnership with LEGO Education, the Raspberry Pi Build HAT is a Hardware Attached on Top (HAT) add-on for any Raspberry Pi single-board computer. Connecting via the 40-pin general-purpose input/output (GPIO) socket, it offers four connectors designed for use with LEGO Technic motors and LEGO SPIKE sensors — as well as optional pass-through access to unused GPIO pins.
“We are excited to work with Raspberry Pi,” claims LEGO Education’s head of product experience Andrew Sliwinski of the partnership, “to provide tools for students, teachers and makers all over the world to expand their creative digital skills and discover hands-on learning experiences.”

New Part Day: Raspberry Pi LEGO HAT
https://hackaday.com/2021/10/21/new-part-day-raspberry-pi-lego-hat/
The Raspberry Pi Foundation have been busy little bees for the last couple of years producing their own silicon, new boards and now in collaboration with the LEGO Education team a new HAT to connect to the LEGO SPIKE education platform. This new HAT board will work with every Raspberry Pi board with a 40-pin GPIO header.
Based on the RPI2040 microcontroller, it makes an interesting detour away from dumb slave boards, although it looks like the firmware is closed (for now) so you’ll have to make do with the pre-baked capabilities and talk to it with the supplied python library.
According to the documentation, the communication between the Pi and the RPI2040 nestled beneath the HAT PCB is plaintext-over-serial, freeing up the majority of the GPIO pins for other uses.

Low Orbit Flux Builds a Raspberry Pi Router with a Compute Module 4 and DFRobot’s IoT Carrier Board
https://www.hackster.io/news/low-orbit-flux-builds-a-raspberry-pi-router-with-a-compute-module-4-and-dfrobot-s-iot-carrier-board-ce52f690928b
Using the Compute Module’s PCI Express lane, it’s possible to pack two full-speed gigabit Ethernet ports into a very compact IoT router.
Pseudonymous maker “Low Orbit Flux” has posted a guide to turning a Raspberry Pi into a firewall and router — getting around the device’s usual lack of a second Ethernet port by adding a DFRobot dual-Ethernet carrier board to a Raspberry Pi Compute Module 4.
“The first [router] that I built was using the original Raspberry Pi with a USB NIC [Network Interface Card], so I had the onboard NIC and a USB NIC,” Flux explains. “That was kind of suboptimal because it was limited by the speed of the USB controller, and that was kind of a bottleneck. So, my new Raspberry Pi firewall router is going to use the Raspberry Pi Compute Module 4 together with this dual gigabit NIC expansion board here.”
