Built this tiny motion tracker with an ESP32-S3 and... an LD2450 radar sensor. The blue pulse hits the target, the speaker pings, and the pitch rises as you get closer. Real tracking. Pocket-sized sci-fi. Would you carry one? #AlienRadar #MotionTracker #ESP32 #LD2450show more

25 Grams of Hardware. 4 Motors. One Flying ESP32-S3.... ESP-FLY is a tiny DIY quadcopter built around the XIAO ESP32-S3. It uses an MPU6050 IMU for motion sensing, four coreless motors, and supports Wi-Fi and ESP-NOW for control. The interesting part is that the flight controller is programmable, so you can experiment with sensor fusion, attitude control, PWM motor control and wireless communication. About 25g with the battery, yet it can actually fly.show more

What If Your Phone Became the Screen for an... ESP32-S3? Droidputter lets you plug an ESP32-S3 into an Android phone over USB-OTG and use the phone as its display, keyboard, GPS and firmware flasher. The ESP32-S3 still runs the application. The phone simply provides the missing hardware. The clever part is that Cardputer apps can be rebuilt with a display and keyboard shim, while pixel data is streamed over the ESP32-S3's native USB-CDC connection. The phone can then flash the firmware and mirror the app. You can even take an open-source Cardputer app from GitHub and build a phone-mirrored version on demand. It is a really interesting combination of ESP32-S3, USB-OTG, Android, PlatformIO and open-source apps. Would you build an ESP32-S3 device that uses your phone as its screen?show more

Which ESP32 board should you buy in 2026? ESP32-C3... SuperMini: Small, affordable, and great for basic IoT projects. ESP32-S3 DevKitC-1: A strong all-rounder for displays, audio, USB projects & TinyML. Look for an 8MB PSRAM version. ESP32-C6 DevKitC-1: Great for Wi-Fi 6, BLE, Zigbee, and Thread-based IoT projects. ESP32-C5 DevKitC-1: Worth exploring if you need dual-band 2.4/5GHz Wi-Fi 6. ESP32-C61 DevKitC-1: Another option for Wi-Fi 6 and BLE projects. ESP32-P4: For advanced camera systems, multimedia & HMI projects. It needs a separate chip for wireless connectivity. My advice: check flash, PSRAM, GPIOs, USB support, and wireless requirements before buying. The chip name alone doesn't tell the whole story. Which ESP32 board would you add to this list?show more

Who says microcontrollers are only for sensors and IoT?... One developer used an ESP32-S3 to create an entire collection of interactive generative art, proving that embedded systems can be a creative medium too. The projects use Adafruit Qualia ESP32-S3 with a 2.1" round TFT display and an IMU for motion-based interaction, while the artwork is first prototyped in JavaScript and then ported to C++ and deployed with the Arduino IDE. Along the way, you will learn about computer graphics, embedded displays, animation, IMU sensors, generative art, optimization, and real-time rendering on resource-constrained hardware.show more

for everyone who still doesn’t believe you can run... local AI on an ESP32: here’s the same class of chip booting an entire operating system. Windows XP boot screen. welcome screen. the Bliss wallpaper. and, of course, an error dialog😁 we went from fitting a 28.9M-parameter language model into an ESP32-S3... to recreating the full Windows XP experience on a tiny 240×240 display. the era of "microcontrollers are only good for blinking LEDs" is overshow more

🔍 Can My DIY Scanner Detect Edible Things? 🍅... I built a DIY object scanner using an ESP32 that identifies objects and displays the results on a tiny screen. 🚀📟 So far, it has successfully identified a tomato 🍅, an apricot 🍑… and then an acorn! 🌰😳 📕 Now the real question is: Would you trust this scanner to tell you what’s safe to eat? 😂 A fun little project combining embedded systems, electronics, and object recognition — but maybe don’t let it decide your dinner just yet! 😅 #DIY #ESP32 #Electronics #EmbeddedSystems #Engineering #TechProjects #ObjectDetection #Maker #IoT #Innovationshow more

three GitHub projects show how much vision can fit... inside an ESP32-S3 esp32-camera handles the first layer: sensor data, JPEG frames, PSRAM, and frame buffers 🖇️ once the camera pipeline works, esp-who adds ready-made vision tasks such as face detection, pedestrian detection, and QR recognition 🖇️ the third project explores a smaller but more ambitious setup: training and deploying a custom vision model directly on the microcontroller 🖇️ put the pieces together and the loop becomes straightforward: capture an image run the model turn the result into a decision trigger something in the physical world a light, a servo, an MQTT event, or a local log the useful part is the short path from something the camera sees to something the hardware doesshow more

The F-22 Raptor looks like a Sci-fi sketch that... somehow got funding, was built with one mission in mind: dominate the sky before the enemy even knows it's there. This fifth-generation stealth fighter combines supercruise (flying faster than Mach 1 without afterburners), extreme maneuverability through thrust-vectoring engines, and advanced stealth shaping that makes it incredibly difficult to detect on radar. But the real advantage is its sensor fusion. The aircraft processes radar, infrared, and electronic signals into one clear battlefield picture for the pilot. By the time an opponent realizes the Raptor is nearby, the engagement is usually already over. Even decades after its first flight, it's still considered one of the most dominant air-superiority fighters ever built. Credit Mark Fingar IGshow more

Billions must watch Yamada on an ESP32 😆

I love this opensource project! Someone just put a... 28.9M parameter AI model on an ESP32-S3. A chip that costs only a few dollars. No cloud. No API. No internet. It runs locally at ~9.5 tokens/s and can generate stories on a tiny screen. This changes the way we think about AI hardware. The next generation of AI toys, robots, and IoT devices may not need the cloud at all. Small chips are getting smarter. 🤖show more
