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.

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.

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.

This tiny ESP32-S3 packs an impressive amount of hardware into 24mm. The M5Stack ATOMS3R is a tiny IoT controller built around a dual-core ESP32-S3 running at up to 240MHz, with 8MB Flash and 8MB PSRAM. It also has a 128×128 color display, BMI270 6-axis IMU, BMM150 magnetometer, programmable button and IR transmitter, plus USB-C and expansion GPIO. At just 24 × 24 × 12.9mm and 6.8g, this is small enough to disappear inside the project you are building. You can program it with Arduino, ESP-IDF, PlatformIO or UiFlow2, so it is a pretty capable little platform for embedded and IoT experiments. At $17.50, it is the kind of board you can throw into a project just to see what you can build. Tiny board. Full ESP32-S3. Lots of possibilities.

An ESP32-S3 with a 3.97-inch e-paper display. What would you build? This Waveshare board combines an ESP32-S3 with a 800 × 480 e-paper screen, making it useful for low-power projects that need to display information without constantly refreshing a backlit display. Think desk dashboards, e-book readers, weather stations, or smart labels that update over Wi-Fi. The e-paper display keeps the image visible even when power is removed, making it a great fit for mostly static information.

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.

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

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.

What if you could run ESP32 firmware without touching a physical board? Espressif's open-source ESP Emulator lets you run firmware binaries for chips including the ESP32-C3, C6, H2, P4, S3, and S31. You can even try it in your browser. Upload a merged firmware ".bin" file and watch the emulator run, with a live view of the console, CPU registers, memory and GPIO activity. For embedded developers, this opens up new ways to test firmware, debug execution and experiment before moving to hardware. Would you trust an emulator to test your next ESP32 project before flashing a real board?

With the new firmware for Brook Gen5X, now we can light up 15 RGB buttons, perfect for Modern Layout that use extra buttons (L3, R3, TP). This upgrade is a must when using All Buttons Controller layout with extra buttons #VM6R B24 and B30. Now we hope Qanba USA will consider to release RGB harness for 15buttons 🙏.
