Every time I think the ESP32-S3 has hit its limit, someone finds another gear. This open-source Jet renderer is now pushing the S3 even harder. Real-time screen-space reflections, water ripple distortion, lens flare and 8 ships on screen, all running on a tiny MCU. Performance dropped from around 60 FPS to 45–50 FPS, but that's still wild for an ESP32-S3. And the developer thinks there is more performance left to squeeze out. No GPU. No desktop CPU. Just an ESP32-S3 doing real-time 3D graphics.

🚀 Introducing COMET Air Mouse 🖱️ I’ve been working on a compact wireless air mouse built around the ESP32-C3 + MPU6050. Instead of moving a traditional mouse across a desk, COMET converts hand movements into real-time Bluetooth HID mouse controls. 🔹 ESP32-C3 🔹 MPU6050 gyroscope 🔹 BLE HID 🔹 Motion-controlled cursor 🔹 Left / right click 🔹 Gesture-based scrolling 🔹 Adjustable sensitivity & smoothing 🔹 Battery-powered design The firmware is now packaged as a ready-to-flash .bin release, making it possible to deploy the device without setting up the Arduino IDE or installing the required libraries. This project has been a great hands-on experience in embedded systems, Bluetooth HID, sensor processing, firmware development, and power management. And this is just V1.0. 🚀 🔥 Top 6 ESP32 eBooks #COMET #AirMouse #ESP32 #ESP32C3 #MPU6050 #Bluetooth #BLE #EmbeddedSystems #IoT #Electronics #Hardware #Arduino #Engineering #Maker

What If Your ESP32 Could Run Real 3D Graphics Without a GPU? 🤯 Jet is a tiny C++17 software 3D rasteriser built for constrained hardware like the ESP32 and STM32. - Runs entirely in software - Integer-only rendering - Native RGB565 - Flat, Gouraud and Phong shading - Affine and perspective-correct textures - Z-buffering and backface culling - Optional CRT, bloom and motion-blur effects - Designed for displays like ST7796 & ILI9488 On an ESP32-S3, Jet can render around 40,000 triangles/sec, with up to about 650 visible triangles at 60 FPS on a 480×320 display.

meet WALL-E no, not the one from the cartoon :) this is a fully 3D-printed, autonomous desk companion running on an ESP32. it uses a local AI voice assistant to process commands in real-time and control its own motors building intelligent robotics just dropped to zero cost...

Made a little device that manages my claude code’s & codex’s on my server… Simple esp32 s3 chip by waveshare. The orchestrator agent works with voice, controls my device remotely with tools, and controls the server. It’s a cool time to make stuff.

Someone built a laser turret that autonomously tracks and pops balloons for a school deadline, on an ESP32. The real story is the debugging: TinyML on the ESP32-CAM alone maxed out at 2fps. Switching to YOLO on a laptop helped but was still too slow. Baud rate bottleneck killed it again fixed by streaming over Ethernet instead, which finally gave smooth, precise tracking. Same $8 hardware philosophy as the article below local AI doesn't need a $3,000 rig, it needs the right bottleneck fixed.

btw this robot runs on a fully open source AI framework called Xiaozhi it turns a $8 ESP32 chip into a fully autonomous voice assistant NO expensive cloud servers or high latency wake-word detection and audio streaming happen locally on the chip: > requires only an ESP32-S3, a microphone, and a basic speaker > supports real-time conversational voice interaction > completely open-source and customizable for any DIY robotics project anyone can now build a personal AI companion for the price of a cup of coffee.

I built a bot on an ESP32 that can create full projects by itself. Ask it to generate images, videos, 3D, build a website and publish it, it does everything autonomously. Powered by Claude Opus 4.6 for code, visual content generated with fal, bot powered via OpenClaw🦞 The skills to generate project with fal are here All running on a tiny M5Stack Core2.

another example: a developer used the exact same $8 ESP32-S3 chip and local AI setup to build a real-time object recognition camera the fact that this is running entirely offline, on an eight-dollar microcontroller, without any cloud API calls, is wild... it captures the video feed, processes it locally through the model, and identifies objects in real-time. we are entering an era where you can just glue intelligence onto any physical object for less than $10. the hardware barrier is completely shattered.

We’re on a path to video of any kind being imagined by a model in real-time. Because it’s real-time generated, each video becomes fully interactive & personalized. Type or speak into the model, and the video will respond in real-time. A revolutionary form of media is emerging!

I took Steve Ruiz's advice & got an ESP32! So much fun for ~$55. I programmed it to display live stats from my online radio station, and use the built-in mic to transcribe and send messages in the station's chat :) Here's everything I bought & how it works: - Waveshare ESP32-S3 1.54" e-Paper AIoT board ($30) - Wi-Fi, mics, speaker, battery charging built in - 3.7V 500mAh LiPo ($10) - JST 1.25 connector adapters ($15 for 20) - ESP32-S3 polls my radio's API over Wi-Fi every 20s → renders a "broadcast console" UI on the 200×200 e-paper - Hold-to-talk: dual mics record → WAV upload → server transcribes w/ OpenAI → posts to the live chat via websocket, pinned as the station owner (API-key auth) - Backend is my Wasp app (React/Node/Prisma) on Railway over 3 tiny endpoints: /status, /chat, /voice-chat - Firmware: PlatformIO + Arduino, GxEPD2 for the display, Waveshare's ES8311 codec drivers for the mic - Runs on battery, fully standalone Built the whole thing in a morning w Claude Fable 5. server endpoints, firmware. A really cool bit was mocking up possible UIs for the esp32 e-paper display using Claude's artifacts. Check out my mixes/shows at
