In this guide, you’ll setup an HTTP (web) server with a Pico W running CircuitPython. HTTP servers are handy for creating custom web interfaces to monitor and control IoT projects.
This example sets a static IP address for the server, logs temperature readings from a DS18B20 temperature sensor, displays server information on an OLED and serves an HTML webpage with buttons that can send HTTP POST requests to toggle pins on the Pico W.

Have a litte fun with your smart home. Inspired by Rick and Morty, donutsorelse developed this wearable control…EVERYTHING (well, a lot of home gadgets and whatnot).
He completes the cosplay with a 3D printed Meeseeks.
Ever wish you could control your smart home like Rick from Rick and Morty? In this video, I show how I built a fully functional “Remote Remote” that works just like Rick’s wrist gadget! With my setup, I can control smart devices from anywhere using WiFi and Blues Wireless connectivity. From turning lights on and off to making the house spooky, this gadget puts the power of home automation right on my wrist.
Using an ESP32, Unihiker, and Flask server, this device communicates with my smart home system through MQTT and OpenAI’s API. It’s even voice-activated! Just say “butler,” and the remote activates, ready to take commands. Plus, when WiFi isn’t available, Blues Wireless kicks in, making this one of the most versatile smart home controllers out there.

The Raspberry Pi USB 3 Hub provides extra connectivity for your USB devices, turning one USB-A port into four. Inside it uses the Infineon CYUSB3340 for 5 Gbit/s USB 3.2 Gen1 support
The USB 3 Hub has been tested to work seamlessly with all Raspberry Pi products, but of course it will work great with any desktop computer or laptop or other USB host device.
The Bluetooth USB HID Relay uses a Raspberry Pi Zero (or similar OTG-enabled single-board computer) to use Bluetooth keyboards and mice with computers that have Bluetooth disabled, by presenting the board as a composite USB HID device.
This project was born out of a desire to help a friend who couldn’t use his favorite Bluetooth mouse and keyboard due to Bluetooth being disabled on his work laptop. As someone who enjoys tinkering and problem-solving, I saw this as an opportunity to create something useful while learning more about Linux internals, USB gadgets, and Go programming. The Raspberry Pi Zero became the perfect bridge, connecting Bluetooth peripherals to computers that wouldn’t normally allow it.

Pieter on Skatterbencher is a frequent overclocker and he’s taken on boosting the new Raspberry Pi 5 to unheard of clock speeds.
We tried everything to make our Pi the fastest Pi in the world. That includes changing the operating system, subzero cooling with liquid nitrogen, boosting the power circuitry, and even swapping out the crystal oscillator.In this blog post I try to share some of the findings and insights from the several weeks of Pi hacking in collaboration with ElmorLabs.
Various methods were used to be able to increase the frequency the Pi would run at:
Whenever you think something might not be connected, art has a way to show you it is. The Baltimore Museum of Art invites you to question the use of colors and patterns in art by combining the works of Matisse with Japanese woodcut artists in one exhibition.
In contrast to Matisse, Japanese woodcut artists working in the 19th century depicted their female subjects more often in public spaces clothed in layers of ornately decorated robes. Prints by some of Japan’s most popular woodcut artists—Kikugawa Eizan, Keisai Eisen, and Utagawa Kunisada—show glamorized courtesans and entertainers frequently depicted as though on parade. The exhibition also features a vibrant sash supplementing those shown in the prints.
Tancrede Collard of QuestDB has been tinkering with Raspberry Pi products with his child. Various projects ensued then a Raspberry Pi Pico powered display from Pimoroni came along.
It then occurred to me that a market-making game would be more interesting.
When market-making, you are quoting on both exchanges and over the counter, hedging in the underlying market and taking/managing risk. A large difference between market making and the previous game is that in market making, you are constantly quoting both sides, and other participants come and trade against you.
To manage your risk, you can trade in the underlying markets. For example, if you sell S&P 500 ETFs, you are short. To mitigate this risk, you can buy a hedge instrument (for example S&P500 futures) which are perfectly correlated to the ETF and therefore render yourself immune to market movements.
A custom PCB was made with the display, Pico, and eight buttons to control all the various actions. Software has been written in MicroPython. Various methods were employed to have the code work quickly and efficiently.
I am truly impressed by the Raspberry Pi Pico, and the micropython language. When I think microcontroller, I think toothbrush control or small RC remote. But seeing it run an exchange, orderbook, matching engine, and refreshing a display for a cost of around $8 is truly impressive.
They just released a new version with more cores, more memory, and other features, and I can’t wait to try it for other projects and to see what more skilled makers will make of it!
We designed and prototyped an RP2350 Metro a few months ago, and it worked OK, but we were really short on pins, which meant a lot of annoying compromises – so we ended up only fabbing the RP2350 Feather to start.
With that design flying off the shelves, It’s time to revisit the Metro.
We wanted to jam-pack this design, and with the extra GPIO on the B we have plenty of peripherals: the 22-pin HSTX for DVI output, Stemma QT port, NeoPixel, JST 3-SH SWD debug port, 16MB flash, an extra spot for PSRAM, MicroSD card with SPI or SDIO connections, and 5V buck converter that can give us 2 Amp easily, which we’ll need since we also have a USB Host port pinout for connecting USB peripherals.
We even managed to get a couple of niceties like switchable power for the USB host power, a USB boot button as user input, and an SD card detect GPIO.

What is a ‘zero’ library? The first ‘zero’ library was Pygame Zero, created by Daniel Pope to address what he saw as an ongoing issue beginners faced when getting started with PyGame software. Pygame Zero was a simplified version of PyGame that allowed for greater accessibly.
Since then, developers have made many other ‘zero’ libraries, now including picamzero, adapted from Picamera2, a used on projects like the Astro Pi. Here’s more from the Raspnerry Pi Foundation:
The Code Club Projects and Youth Programmes teams at the Raspberry Pi Foundation have joined forces to create picamzero: a new library that makes it simple for beginners to use the Raspberry Pi Camera board.
As with the other ‘zero’ libraries, it’s straightforward to get started.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Check out the latest tutorial from Erin St Blaine: build a Halloween illusion that transforms your face into the face of a skeleton or monster. This prop can also be used to blend your face with your friend’s face. It uses a Feather ESP32 board and NeoPixel LEDs with a 2-way mirror to create all the spookiness.
From the guide:
Get spooky this year with a magical halloween coffin that holds a surprise inside. A 2-way mirror and an array of animated lights creates a face-blending illusion, melting your face into a creepy skeleton or other Halloween monster. You can also prop this up and blend two human faces together, creating a very creepy and surreal experience.
This project requires a little soldering and some software installation, but no coding. We’re using an ESP32 Feather board to program and control our lights over WiFi, so you can control and change the colors or animations with your smart phone or any web-enabled browser.
This illusion was inspired by TANZER’s Infinity Boxes, and first created by us for Maker Faire 2024, where we built it inside a Love Tree. It turned out so good that we wanted to recreate it to scare the kids in our neighborhood on Halloween!
Content Summary:
– The guide provides instructions on creating a Halloween prop that uses an illusion to transform the viewer’s face into a skeleton when they peek inside a coffin.
– It includes details on setting up lighting effects that enhance the illusion, making for a spooky and memorable Halloween experience.
Adafruit Products Used:

NEW PRODUCT – Raspberry Pi Touch Display 2 – 7″ 720×1280 with Capacitive Touch
Raspberry Pi Touch Display 2 is the sequel to the popular Raspberry Pi Official Display. Like the original, it’s a 7′′ touchscreen display for Raspberry Pi. Unlike the original, it has a much higher quality IPS TFT screen, the same kind used on tablets. That means it looks great at any angle, and it has much higher resolution too, 1280×720 rather than 800×480! It is ideal for interactive projects such as tablets, entertainment systems, and information dashboards.
Raspberry Pi OS provides touchscreen drivers with support for five-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse. No coding or special drivers required, everything works out of the box if you’re running the latest Pi OS.
Only two connections are required to connect the 720×1280 display to your Raspberry Pi: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line. The Pi can be mounted on the back for a cute all-in-one setup.
The display can be configured for portrait or landscape mode. Check out the installation guide for how to get started fast. No tools are required, it’s plug-and-play easy!
Check out the latest Learn Guide from Erin St Blaine: Make a star crown inspired by the headdress worn by Hedy Lamarr in Zeitgeist Girl (1941). This is a fantastic beginner project that requires a little soldering and some crafting skills, but no coding at all. Learn to install WLED on a microcontroller and hook up Adafruit’s new star-shaped NeoPixels. The crown is made from an inexpensive headband with zip ties for the spokes.
Sparkle like a 1940s starlet with this DIY star crown, inspired by the iconic Hedy Lamarr in Ziegfeld Girl (1941).
Hedy Lamarr wasn’t just another Hollywood beauty—she was also a fearless inventor, and wicked smart. While making headlines with her glamorous and sometimes scandalous roles (like in Ecstasy, where she became famous for one of Hollywood’s earliest nude scenes), Hedy was secretly working on a groundbreaking invention to help win World War II. She co-created a “frequency hopping” system to keep Allied torpedoes safe from jamming. That tech became the foundation for what we now use in Wi-Fi and Bluetooth.
In this tutorial, we’ll channel that mix of glam and genius to make a modern, glowing star crown with NeoPixel stars and WLED, perfect for cosplaying the timeless Hedy or adding some sparkle to your next event. Let’s dive into some Old Hollywood glam meets high-tech magic.

Here’s a story that isn’t true: a group of esotericists create an imaginary country built out of alternate mathematics, aesthetics, and philosophies. To make the world feel, they write an encyclopedia enumerating in bland, painstaking details of their imagined country. In the same way that the original encyclopedia brought the our own world into the imaginations of people all over Europe, this encyclopedia of the imagined country is so real, so specific, so alien, so plain, so clear, that it begins to manifest on the real world. Like an invasion of the imagination, the imaginary country soon overtakes our own, and we find ourselves in a world that never was. That’s an imaginary story that may well be the plot of a short story by a certain Argentinian writer of some renown.
Here’s a story that is true: in 2022 Vorja Sánchez self-published his own volume of an imaginary world, Invisible Home. Sánchez’s work could easily have invaded from an imaginary country. His poetry in particular feels like something one might find if they fell into a Pottery Barn from another world. Here’s more from imaginary from COLOSSAL:
Beastly jugs and vessels with legs comprise the latest in illustrator Vorja Sánchez’s eclectic and uncanny menagerie. A new print titled “Ancient Pottery” draws inspiration from a wide variety of stoneware urns, bowls, and statuettes from prehistoric cultures around the world, imbuing each of them with the lively features of animals or mythological beings. Produced from an original piece made with pencil, ink, and watercolor on cotton paper, the artist emphasizes the appearance of age, as if a patina has formed over time across the entire composition.
“I am fascinated by the simple and imperfect but pure and free forms of ancient ceramics,” Sánchez tells Colossal.

Musician Laurie Anderson has a spin on reusing magnetic tape to create new sounds. She created a violin bow strung with audio tape instead of horse hair.
By drawing the bow across the violin strings, she can play the sound captured on the section of tape backwards and forwards.
Laurie Anderson repurposed a section of tape to say a phrase in Dutch when drawn forwards across the strings. By pulling the bow back, the phrase is played backwards, sounding out a phrase in English. What an inventive way to repurpose not only an old audio tape, but also sound itself!
This week, we finally got the last parts required to convert our Desk to standing – yay!
We also got some cool swag from LINAK, including a desk-mount USB PD power hub, which we discovered could do 20V output, which means it can power our ember mug using a 20V USB to DC adapter cable. That plus some under-desk cable management and we’ve cleaned up the Desk quite a bit.
We covered the Lepton infrared cameras on EYE ON NPI, which made us think about designing an EYESPI-compatible breakout with which the sensors can be used.
We also chatted with some Adafruit’ers about designing an RP2350B-based CircuitPython/Re-mapping Gameboy Cartridge.
Finally, JP asked us to design a DMX FeatherWing much like the MIDI FeatherWing.
salimbenbouz shared this neat project on instructables, thingiverse, and Github! If you’re into 3D printing and Pi projects, they’ve combined the right amount of nostalgia in this miniature PC.
Inspired by the retro machines I grew up with during the 90s and early 00s, I decided to design and build a working tiny miniature PC to bring a little of that nostalgia to my desk. In this guide, I’ll walk you through the entire process of building one, sharing detailed steps and tips to help you recreate this project.

What do you think of when you think of a hacker? Today hackers have taken on international status as government-funded agents who can change the course of history. We might imagine a shadowy government funded team in some droll office performing the 21st Century version of foreign interventions. That wasn’t always the case.
Forty years ago, hackers were thought of a nerdy solo acts. You might think about a particularly geeky Matthew Broderick accidentally pushing the world toward global thermonuclear war while trying to impress Ally Sheedy in WarGames. Hackers for quite some time were seen as basement dwelling, Doritos munching outsiders ready to break the law through nerdy means just to get a little status.
In 1995 that all changed. The movie Hackers dramatized in a very Hollywood sort of way what had already happened: rave culture, electronic and synth-based music, the early wild-west internet, conspiracy theories (back when they were fun), Blade Runner aesthetics, and a very cyberpunk view on politics, had converged into a bleeding-edge cool. This vibe transformed the zeitgeist so much that by the turn of the century everybody was fluent in the visual language that first surfaces in the mainstream with Hackers.
Here at Adafruit, we love Hackers. One of the most fun Raspberry Pi projects we’ve seen comes from the ever-reliable HackersCurator. A re-creation of Nikon’s laptop, powered by Raspberry Pi. Here’s more:
We recreated a fully functioning reproduction of Lord Nikon’s laptop from the iconic cult classic film Hackers from 1995. Here is how we did it, and you can too! In Hackers, Lord Nikon A.K.A. Paul Cook, played by Laurence Mason sports an iconic laptop and startup sequence from the film. We wanted one that actually works. We captured the entire process on Twitch and have compiled the build into this video.
