PiMyLifeUp shared how to power your Raspberry Pi using Power over Ethernet (PoE).

The PoE standard is a neat way to power devices without needing to plug them in physically to a power point. Power is instead delivered over your ethernet connection, this is super useful if you have to run an Ethernet cable to your Raspberry Pi anyway.

Powering over ethernet can also be done pretty affordably; you can get PoE-enabled switches for a reasonable price if you shop around without needing to invest in more expensive hardware from companies like Ubiquiti.

With the Raspberry Pi 3, the Pi team introduced functionality for PoE onto the Raspberry Pi boards. The one catch to this is that you have to invest in a HAT to add the power over ethernet functionality. The board simply exposes the power pins from the Ethernet port so that they can be utilized.

Do you ever feel like someone or something is watching you? In the case of this project, it is! You can use a Fruit Jam running CircuitPython with a USB webcam to display monster eyes that gaze in the direction of motion captured by the webcam. The CircuitPython code utilizes Turbo helper modules to speed up tasks like drawing the monster eyes and checking for new motion in the camera frames.

Turn your hair into a motion-reactive light show with these colorful LED Bubble Hair Extensions from Erin St Blaine.

This wearable project combines lightweight LED seed pixels with bright bubble-braid hair extensions to create glowing cyberpunk-style hair that reacts when you move. An LIS3DH accelerometer senses a shake of your head and kicks the animations into high gear, transforming a gentle falling-rain effect into a dramatic storm complete with flashes of lightning.

The LEDs are controlled with CircuitPython, so it’s easy to customize the colors, animation speed, and motion sensitivity to create your own look. It’s a fun project for festivals, costumes, cosplay, performances, or anywhere your hair could use a little more magic.

From the Guide

Make glowing LED bubble hair that reacts when you move your head!

In this project, six strands of seed pixels are built into a hair extension and controlled by an Adafruit RP2040 Prop-Maker Feather. The LEDs show a soft color gradient during normal wear, then the onboard accelerometer detects a head shake and triggers animated rain effects.

A gentle shake creates staggered glowing droplets that fall down individual strands. A stronger shake creates a lightning flash followed by a faster, denser rainstorm.

This is a fun project for festivals, costumes, cosplay, dance performances, or anyone who wants a little weather system in their hair. You’ll need to install some software, and there is a bit of tricky soldering involved — this is not a beginner project because of that, but it is very accessible to anyone who has some soldering experience.

CircuitPython recently gained support for bulk transfers from USB host devices on the RP2350. That unlocks the ability to use USB software defined radio devices on the Fruit Jam. This guide covers a basic AM/FM & Weather radio tuner project. You can load up your favorite stations as presets, or surf up and down the radio waves with manual tuning. A user interface is displayed using the Fruit Jam’s DVI output. The tuner can be controlled with the 3 on board buttons or a USB keyboard. Audio is output from the Fruit Jam’s 3.5mm output connected to the onboard TLV320 DAC.

The guide covers how to load the latest firmware on the Fruit Jam, assemble the parts needed, install the code, and how to control the radio using buttons or keyboard.

Atypical workshop built this time-lapse camera to document a garden renovation. He goes through the whole process from stabilizing the camera, building the housing, installing the hardware and a cost breakdown at the end. A step-by-step guide is in the works but for now you can checkout Github, YouTube, and Reddit for details:

I built a time-lapse camera around a Raspberry Pi 4 with a Camera Module 3 Wide, powered over a single PoE cable, and I’ve open sourced the software. The Pi takes a full 12MP photo every minute in daylight only, working out the window from your latitude and longitude so it follows the seasons, and it looks after its own storage by deleting the oldest frames once the SD card passes 85%. A Mac collects the frames automatically whenever the archive drive is plugged in, and one command turns any date range into a video. There’s also a film mode and you can control it from your phone.

Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!

You can turn a microcontroller into an I2C target for a second microcontroller. What is this witchcraft?

Matt Keeter has released Halfspace, an experimental IDE for solid modeling with distance fields, and written about it on his site. It is a GUI wrapped around his Fidget geometry kernel, which handles rasterization and meshing. Models can be built from pre-defined primitives and hand-written scripts, then exported as images or triangle meshes. There is a browser demo, best run on a desktop with WebGPU support.

Rather than hiding the math behind constructive solid geometry operations, Halfspace puts the distance fields in the foreground. Keeter shows two sawtooth fields with identical signs everywhere but different values. One has a jump discontinuity at the vertical edge, which breaks the normals that Fidget computes through automatic differentiation and produces wrong shading in 3D. Seeing the field makes that kind of bug easy to spot.

The project also drove work on fidget-wgpu. CPU rasterization was too slow through WebAssembly, so rasterization and post-processing now run entirely on the GPU with no hits to the CPU. Keeter has worked on it since April 2025 and notes it is not vibe-coded. It is open source under MPLv2.

Michael (@micthiesen) has published key-right on GitHub, a Rust firmware project that swaps the Realtek controller in an Elgato Key Light for an ESP32-C3-MINI-1. The rest of the lamp stays: the PCA9635 LED driver, the stock driver circuitry, the LEDs, and the power supply. The point is local control from Apple Home over Matter and WiFi, with no cloud.

Each lamp shows up as one Matter Color Temperature Light with power, brightness and white temperature. Home’s 1 to 100 percent brightness maps to the stock nominal 1 to 10 percent range, so Home 100 percent is a low-light ceiling. Temperature covers 143 to 344 mired, roughly 6993 K to 2907 K. Two lamps pair separately and then get grouped in Home.

The ESP32-C3 talks to the retained PCA9635 over I²C using GPIO4, 5 and 6 for SDA, SCL and OE, and takes power from the lamp’s 3.37 V rail. Version 0.1.4 adds 400 ms eased transitions.

Mahmoud Aly has published Micro REPL on GitHub, a MicroPython IDE that runs on Android, Windows, macOS, Linux and in the browser. Plug a board in over USB and you get a live REPL, a file explorer and a code editor with the same layout on every platform.

The terminal runs code, keeps command history, soft resets the board and stops a script caught in a loop. The explorer browses the board’s storage so files can be created, renamed, deleted, run or imported from the device. The editor has syntax highlighting, undo and redo, and keyboard shortcuts on desktop: F5 runs a script, Ctrl/Cmd + S saves it. Recently opened files come back after a restart, and there are more than 20 themes that color the whole app.

The browser version uses Web Serial, so it needs Chrome, Edge or Opera on desktop over HTTPS or localhost. On Linux, the desktop app offers to install a udev rule the first time it cannot open a port. The Android build comes in two flavors, one with no analytics and one with Firebase.

Micro REPL is MIT licensed.

Weeb Labs has published DSPi on GitHub, a firmware that turns a Raspberry Pi Pico or Pico 2 into a USB sound card with an onboard DSP engine. It handles room correction, active crossovers, parametric EQ, time alignment, loudness compensation, and headphone crossfeed.

Both chips run at a fixed 307.2 MHz system clock, which keeps the PIO dividers integer at 44.1, 48 and 96 kHz. The RP2040 needs a small voltage bump to get there. The RP2350 has more headroom thanks to its hardware floating point unit, so it supports 11 channels and 9 outputs against the RP2040’s 7 and 5.

Each output slot can be switched between S/PDIF and I2S at runtime, and a single device can mix the two. Output pins can be reassigned without reflashing, and assignments are stored in flash with one of 10 presets. A delta-sigma modulator on Core 1 drives a PDM subwoofer output through a simple RC low-pass filter.

The firmware is GPL v3 and builds with the standard Pico C/C++ toolchain.

RTL-SDR.com has posted work from Zoltan Doczi, who sped up the ESP32-SDR sampling time by about 50x. The ESP32 has undocumented features that let it work as an SDR, but USB bandwidth is too small to send the full 80 MS/s I/Q stream to a PC. Until now, spectrum data went out in bursts with roughly 42 ms gaps between them.

The fix was a data buffer ring spread across three SRAM banks, so the dump engine never stops. In turbo mode at 80 MS/s and 256 bins with the filter wide open, the chip produces 1295 spectra per second, gapless. The article includes characterization measurements taken with a Signal Hound VSG60 signal generator.

The same SRAM buffer work enabled real I/Q output, capped at 250 ksps. Doczi wrote sdrpp-esp-sdr-source, an SDR++ source module, to receive that stream on a PC. Using a moRFeus as an upconverter with the LO at 2259.1 MHz, a 90.9 MHz FM broadcast station was mixed up to 2350 MHz and received in SDR++. The module can also stream the full 80 MHz spectrum, but that is display data only with no demodulation.

See the video below and more on rtl-sdr.com and content on GitHub.

Windows Central reports that Microsoft has made WSL Containers generally available. The feature puts Linux container support directly into the Windows Subsystem for Linux, so developers on Windows 11 can run containers without installing a third-party tool like Docker Desktop first.

Containers bundle an application with the dependencies it needs, so the software behaves the same way on different machines. Microsoft announced WSL Containers at Build 2026 and has been testing it since. Features added during that period include container health checks, real-time event streaming, more networking controls, configurable storage locations, and additional container management commands. Enterprise controls are coming too, with Intune policies and Microsoft Defender for Endpoint support.

The new command-line tool is called wslc, and its commands will look familiar to anyone who already works with containers. Docker Desktop and similar tools still work, so this is an alternative rather than a replacement. Most Windows 11 users will never run a container at all, but for developers it is one less application to install and keep updated.

Adafruit Forums user paul_collins_iii had an engineering itch to use an Adafruit MagTag as a glorified timer.

Originally started doing this in CircuitPython, but the button presses had some serious delay before the device would respond just due to the size the code base was getting to. Converted to C with esp-idf and a lot of Claude.

The MOE-Timer (https://github.com/paulcollinsiii/moe-timer) is a kid-friendly timer for tracking screen time. Controllable from Home Assistant, with different screen time grants for Summer / Holiday / Weekend / Week days. Support blocking off some or all screen time till chores are checked off, additional custom timers (piano practice etc.), enforcing screen breaks and reporting back to HA.

Challenges:
* No RTC means Wifi and NTP is basically required. It doesn’t check every time, because the clock drift isn’t completely insane but it does have to check.
* MQTT integration for HA. Enh, esp-idf has really good support for mqtt, json and provisioning so no big deal.
* e-ink in C is a touch involved. Making that Claude’s problem is not so involved.

Several weeks of ClaudePro tokens later, this project sees daily usage by a kiddo.

See the project on the Adafruit Forums.

Péter Szentkirályi has released Darkplug, a darkroom timer app for iPhone and iPad that switches an enlarger on and off through a smart plug on the local network. The app works with Shelly plugs. Setup means connecting the enlarger to the plug, putting the plug and the iOS device on the same network, and entering the plug’s local IP address in the app.

Darkplug times exposures the way a classic darkroom timer does, and adds workflows for test strips, dodge and burn sequences, and split grade printing. The interface is red on black. The specific red was chosen and tested so it will not fog photo paper sitting next to the device.

A paid tier, Darkplug+, adds the more advanced tools. It is a one-time in-app purchase with no subscription. The app is on the App Store now.

Guenter Bartsch has published lxa, a Linux Amiga emulation layer on GitHub. It runs AmigaOS executables natively on Linux in the way WINE runs Windows programs. A 68000 CPU emulator is paired with AmigaOS library implementations, and system calls are bridged to Linux file and I/O operations. On first run it creates a ~/.lxa/ directory with the system files it needs.

Because lxa targets OS-compliant applications only, it does not emulate ECS or AGA chip registers. Display goes through RTG with Picasso96, so true-color screens at arbitrary resolutions are possible. The stated goal is a development platform for Amiga software on Linux: productivity applications, IDEs and GUI toolkit apps running on a Linux PC or Raspberry Pi with no Amiga hardware.

Development is checked against a real AmigaOS 3.1 reference machine. A twin runner executes the same scenario on lxa and on the reference, then compares Intuition trees, pixel snapshots and text output. All 9932 executables from the Fred Fish collection have been run under lxa. Version 0.11.28 closes milestone M2, with GELs, copper lists, PaletteExtra and library versions matching AmigaOS 3.1.

James Pickstone, writing on openrepair.org, previews what communities have planned for International Repair Day on October 17. This is the 10th edition, and the global event map is still filling up.

Vienna’s re:pair Festival runs 17 days, with textile workshops, furniture restoration demos, musical instrument repair clinics and a repair cafe. Vivita Philippines is running a Repair Fair with Mt. Cloud Bookshop as part of Design Week Baguio, bringing 3D printers, sewing machines and soldering kits. The Restart Project is holding London’s first Festival of Fixing with the City of London and the Barbican.

In Portsmouth, the local Repair Café and Library of Things are running Circle Fest, which includes a Tech Amnesty for old gadgets. Bath has FixFest, Edinburgh has Pianodrome’s Make It Yourself Festival, and Repair Cafe Pavia is working with the University of Pavia on workshops covering soldering, bike repair and Kintsugi. Ecological News and the Black Sea Maritime Professional College are holding a repair festival in an underground shelter in Chornomorsk.

The Open Repair Alliance also plans to release a larger version of the Open Repair Dataset on October 17.

Developer bclml has released mcIRC on GitHub, a desktop chat client for MeshCore LoRa mesh nodes that copies the old mIRC layout: a window tree on the left, a switchbar of direct message buttons, and unread windows turning red. It works with any board running MeshCore Companion firmware over USB, Bluetooth or WiFi. It is written for Windows, with Linux and macOS support marked experimental.

Besides channels and private messages, it shows a map of every node the radio has ever heard, past the 350-contact limit of the radio itself, plus full node settings, per-window logs, slash commands and five color themes. A demo mode runs without a radio.

Everything beyond chat is an addon. The project started as the BC traffic bot, which polls DriveBC, BC Ferries, BC Transit, TransLink, weather, earthquake and tsunami feeds and broadcasts incidents to separate mesh channels, with a follow-up cleared message when an incident drops off the feed. An Auto reply addon handles keyword responses.

The code is MIT licensed and the author suggests the pattern should port to other regions with open data feeds.

Marcin Wichary, writing on aresluna.org, tells the story of his first hack. As a teenager in the early 1990s he had a hand-me-down PC clone with an EGA card and a 14-inch cathode ray tube. The tube began to fail. The picture warped and bulged within three minutes of warming up, but only in the 320×200 mode. The sharper 640×350 business mode still worked fine.

Every game he cared about, including Civilization, used the low-resolution mode. A new tube was not affordable. So he wrote a TSR program in assembly language that intercepted any attempt to switch to 320×200 and forced the display into 640×350 instead.

Civilization kept drawing as if nothing had changed. Odd lines landed in the top left of the screen, even lines in the top right, and the game occupied about a sixth of the display with unreadable text. It worked. He played that way for months until he could afford a new card and monitor.

A post on mihai.dinculescu.dev explains why Tapo smart plugs started returning 403 Forbidden to scripts that had worked for months. Firmware 1.4.0 brought a new protocol, TPAP, and plugs will only talk the old way when the “Third-Party Compatibility” switch is on in the Tapo app. That switch is off by default. Lights followed on firmware 1.4.1 to 1.4.3.

Version 0.11.1 of tapo, an unofficial Rust and Python client for TP-Link Tapo devices, speaks TPAP. Lights, plugs, power strips, hubs and cameras work with the switch off, by IP address or through discover_devices, with no code changes. The client works out which protocol the device uses. TPAP logs in with SPAKE2+ (RFC 9383) instead of the hash exchange KLAP uses, so a recorded login cannot be taken away for offline password guessing.

Three releases landed within a week. They also added handlers for the H200 and H500 camera hubs, including listing and downloading recordings as MPEG-TS clips, plus schedule and timer support for plugs that run on the device’s own clock. The legacy AES protocol was removed in v0.11.0.

From the mail bag!

Hello Adafruit team,

Your CircuitPython introduction makes a lovely point: after a board is set
up, saving an edited file is enough to run the change. That short distance
between an idea and its result makes experimentation feel approachable.

Thank you for explaining the process so clearly and for building a place
where people can learn how electronics work.

Best,
Ray

Researchers from the University of Massachusetts Amherst have designed a flexible mesh that integrates electronics with human cells. The mesh is capable of providing a continuous electrical supply. The study was recently published in Science Advances. Their ‘biohybrid mesh harvester’ could change the way wearables and implantable electronics are powered.

Harvesting that cellular power requires a paradigm shift in electrical engineering—a shift that Yao, who has previously demonstrated a mesh that can grow with and monitor heart tissue, built an artificial neuron that can communicate directly with human cells and discovered how to harvest clean energy from thin air, is leading.

T-Kuhn has built the Hexa-Bouncer, a ball juggling machine published on Electron Dust and the successor to the Octo-Bouncer. It is a rotary hexapod that uses universal joints on all six arms instead of ball joints. An IK simulation in Unity showed the upper joint also needed to rotate around the end link’s axis, so a wrist joint was added to each arm.

Two cameras mounted 120 degrees apart send image data to a PC over USB at 120 frames per second. The Unity application extracts a 3D ball position every 8.33ms, predicts when the ball will come back down, and runs PID control on the X and Y axes to set paddle tilt.

The harder problem was pulse generation. Running IK for all six arms on the Teensy 4.0 at every pulse interval was too slow, so T-Kuhn sends precomputed motor profile points and interpolates between them. With points spaced close together the reproduced curve is nearly identical to the target, which is enough given backlash in the stepper gearboxes. That allows moves like rising and falling while tracing a circle.

See the video below and more on electrondust.com and content on GitHub.

Easy Flash is a browser based tool for writing firmware to ESP32 boards. Pick a hardware project from the list on the page, connect the board, and the flashing happens in the browser with no toolchain to install.

It uses the Web Serial API, so it needs Google Chrome, Microsoft Edge, or another Chromium-based browser. Firefox and Safari will not work. When the write finishes, the tool resets the board and reports the firmware version it installed, such as v1.2.4.
