Great project write-up by Sourav Gupta up on CircuitDigest.
To save the Pi during uncertain power falls or unintended shutdowns, a UPS can be constructed, same as the UPS backups which are used in our home or offices. Here in this project, we will make the RPI UPS power supply that could provide sufficient time to save the code in RPi as well as this can be used as a separate power supply unit for backup also. We have built this project on PCB and have used PCBWay to fabricate the boards for this project. In the following sections of the article, we have covered in detail the complete procedure to design, order, and assemble the PCB boards for this Raspberry Pi UPS Hat from PCBWay so that you can also easily build one on your own. So let’s get started.
This is a writeup of a project I did for my Introduction to Making class. I was inspired by my wife who wanted a device that automatically rotates her plant so that each section gets an even distribution of sunlight.

A couple simple projects from Les Pounder on Tom’s Hardware demonstrating the power of CircuitPython on the Rasperry Pi:
CircuitPython can also be used on the Raspberry Pi and via two projects we introduce how to use CircuitPython with the Raspberry Pi. The first project is the humble LED, controlling how to blink an LED enables us to understand how we communicate and control components. The second project involves using additional components connected to the GPIO via a jumper wire to Stemma QT connector.
CircuitPython on the Raspberry Pi is transferable to other devices, such as Adafruit’s QT Py RP2040, Feather RP2040 and Pimoroni’s Keybow 2040, along with the Raspberry Pi Pico. So the skills learned here are applicable to any board that can run CircuitPython

Track down ghosts with this super authentic PKE meter. If you were a fan of the show growing up, you remember how vital this tool was. From Starscream205 on Instructables:
There was one cartoon in particular that seems to dominate my childhood memories and that was The Real Ghostbusters. Ray, Winston, Peter and Egon were armed to the teeth with really cool gadgets, among them the PKE meter. This was my favourite of all their tech and it basically detected the ghosts they were trying to hunt.
What I am going to do is make my own fully functional PKE meter.

A custom, low power temperature sensor powered by a Raspberry Pi Pico with an LCD display and WiFi connectivity for integration into an MQTT home automation hub.
For a number of years now, I’ve been wanting to monitor room temperatures across my house to assess the effect of multiple heating sources and insulation efficiency. Best practice would dictate that I have multiple sensors running in parallel to get data points that are relative to one another. For multiple sensors to be running constantly, I’d prefer it to be low powered and low cost to maximise the number of units I can have in the setup. For ease of setup, it would be preferable for each unit to be wireless to allow temperature data collection to be performed in a single location and for each unit to only require a power connection.

I have a gradually growing Twitter account for my website to showcase my projects and articles. Most of the time, I forget to check if there is a change in the follower count of my Twitter account to discern the account growth chronologically. Thus, I decided to create this apparatus placed on my desk, which displays information of my Twitter account:

“Food Computer” may be a bit misleading as a description for this project. The machine is less like a computing machine made from tasty snacks, and more like a fully-automated plant growth station. Here’s more from Raspberry Pi Blog:
“It is a fully automated growth chamber that can monitor over a dozen atmospheric and root zone variables and post them to an online dashboard for remote viewing,” Chris Regini tells us. He’s supervising both Noahs in this project. “In addition to collecting data, it is capable of adjusting fan speeds based on air temperature and humidity, dosing hydroponic reservoirs with pH adjustment and nutrient solutions via peristaltic pumps, dosing soil with water based on moisture sensor readings, adjusting light spectra and photoperiods, and capturing real-time and time-lapsed footage using a [Raspberry Pi] Camera Module NoIR in both daylight and night-time growth periods.”

Who doesn’t like looking at dogs? Ryder over at Ryder Calm Down does. And he’s using Raspberry Pi to up his game. Here’s more from Ryder Calm Down:
Quarantine isn’t great, but looking at dogs makes me feel better. So I built a machine that notifies me when a dog passes in front of my house so I can go look at it.

Hi all,
Just a simple multilevel Hexagonal Key tidy.
There are 3 heights of key fob to match the varying heights of the holder. Below are the quantities of each you would need to print to fill the holder but I think it looks better if you leave some gaps

These templates allow you to mark rounded corners for 1/2″, 3/4″, 1″, and 1.5″ corner radii. Hook the template over the corner and mark with a sharp pencil. Then saw and sand to the line. I have also included a four-in-one template.

The arm has been created by a group of e_nable France Makers, for Gaspard15 year old boy born without left arm.
He can activate the hackberry fingers with a mobile bone raising up from his shoulder.
The arm is mechanical
The shoudler is using a lockable joint ball,
The elbow is using a ball_lock rotation
All mechanical locks commands are on the forearm to be easy to access from the right hand.

DIY USB-HID With a Twist of Lime
Make a custom USB-HID keypad in the shape of a citrus fruit. This keypad features six mechanical switches for controlling media players like Spotify, iTunes, YouTube, etc. Powered by the Adafruit QT Py RP2040 and CircuitPython.
Inside the case is a NeoPixel Jewel that slowly fades in and out making the keypad illuminate. The QT Py and NeoPixel are housed in a 3D printed case with part that snap fit together.
Lemon, Lime and Fruits
The case and key caps can be 3D printed in different colors. Choose a color scheme that best matches your preferred flavor of fruit. Could it be an orange, a lemon, a lime or maybe a watermelon? You decide!
Kailh Mechanical Key Switches
Click, click, click… Mechanical key switches offer a tactile feeling and there’s a few varieties of switch type. Choose the type that best suits your preference.
Custom Keys
One of the goals of this project was to create a unique layout for a keypad. Originally conceived as a circular keypad, the enclosure evidently turned into a fruit inspired shape. As a result, the key caps are cute little triangular pieces.
