Make

From an exciting array of low-cost hardware to more plug-and-play training modules, it???[ s easier than ever for makers to incorporate machine learning into personal projects. In the new issue of Make: (Vol. 77), we take a look at new tools you can use to train AI modules right now like Tensor Flow, Edge Impulse, and Lobe, and show how to use frameworks like Tensor Flow Lite to squeeze trained AI onto a Raspberry Pi or Arduino. Our cover story details how to make an AI-empowered artificial nose that can sort coffee from tea, or identify whatever else you train it to smell. Next in this section we show: how to build a teddy bear that listens and Tweet-shames you when it hears a swear word, how to make a trash-sorting camera using Lobe and Raspberry Pi, and how to monitor your 3D printer for failed prints with an AI watchdog. Plus, get the inside scoop on Tesla coil-powered band ArcAttack???[ s new mini musical coil kit. Also find 23 projects inside, including: Track meteors entering the atmosphere with a Raspberry Pi Modify a vintage iPod to stream music from Spotify Make an animated light-up skirt with 120 hidden full-color LEDs that respond to your movements Add some arctic ambience to your home with a quick Arduino-powered Aurora Borealis light setup And much more!

In this issue's cover story, we go inside how an FX team built a working R/C prop of the famous disembodied hand "Thing" from Netflix's Wednesday, and how you can bring your own props and robots to life with channel mixing, telemetry, and on-the-fly programming using OpenTX for your R/C transmitter. Then, we dive into exciting DIY music projects, starting with the burgeoning synth DIY (SDIY) scene. Get the ins and outs of how to kit out your modular synth setup, then build your own simple synth and learn what makes it squeal with the Mt. Brighton Avalanche Oscillator. Or, go low-tech with a great-sounding Soda Bottle Marimba you can build for pennies, or 3D print your own speakers and instruments. Plus, 33 projects and skills, including: Program animations for mechanical flip-dot displays Sharpen your knife skills by carving a chain from a tree branch Etch custom designs into brass using salt water and electricity Carve two different universal clamps for your CNC projects Learn tips and techniques for getting glass-like 3D prints from clear filaments And much more!

In this issue of Make: we make friends -- literally! Build your own companion robot with a Raspberry Pi 5, and then give it a voice using AI and a large language model running locally. No internet required! Or keep it simple and build a friendly bot with a micro: bit and a few servos. Next, get an overview of the latest new dev boards, including offerings from Adafruit, Seeed, Sparkfun, Pimoroni, and more, that use Raspberry Pi's second-gen, double dual-core RP2350 chip. And, get started with new Arduino libraries and example projects for cheap ESP32+LCD boards. Special Bonus -- Make: Guide to Boards 2025 You know Raspberry Pi and Arduino, but the waters run deep for microcontrollers and single board computers. From wearables, to Wi-Fi and Bluetooth, to AI capabilities, we show you 77 new boards that have exactly what you're looking for to power your next project. Plus, 38+ projects: Embed tiny mirrors and mesh into your 3D prints to create sparkling fabrics Build an autotune kazoo Make a battery using your favorite sports drink Laser cut a creative ski chalet birdhouse for your feathered friends Use an Arduino for professional looking DMX lighting Make a walk-in camera obscura to project the outside world inside (and upside down) Expose spy tech with the budget K18 Bug Detector And much more!
