6 hand-picked embedded projects shipped on X. Every card is a real demo or repo, not a screenshot thread.
Cheap 128×64 LED matrix driven by an ESP32. Rewrote the demo in Rust for more color depth and smoother animation than Python.
First hardware project: ESP32 mesh nodes with RTOS, MQTT scheduler, time sync and a web server to monitor anything.
High-frequency real-time pressure sensing system built with M5Stack hardware and Grok Build.
This year's DEF CON badge runs open-source RISC-V silicon you can visually verify against the published RTL with an IR microscope. Doubles as a security key.
Tiny open-source AI model running fully offline on a few-dollar ESP32-S3 chip at ~9.5 tokens/s. No cloud needed.
Custom local AI running on an $8 ESP-32 that tracks humans with zero computational delay.
Rewrote this demo in Rust and it performs phenomenally better than the Python version. More color depth, and smoother animation. Impressive for a dirt cheap ESP32 μc. Unfortunately, my iPhone camera does a poor job of capturing the color at night so you'll just have to believe Show more
built my first hardware project. It's a node (will be multiple nodes in a mesh) that's used to monitor anything. built scheduler to handle mqtt messages, used rtos, time synchronization between nodes and a web server... all running on esp32 been loving this
The @DEFCON 34 badge packs a surprise: Andrew "bunnie" Huang's "mostly-open" Baochip-x1! hackster.io/news/the-def-c…
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 Show more
this creator just built a zero-delay auto-aim system on an $8 microcontroller he deployed a custom local AI algorithm on a cheap ESP-32 to track human movement with absolute 0-pixel accuracy. the system completely eliminates standard computation delay. it processes the bounding Show more
finally! local AI is accessible to everyone. we replaced our massive smart home server with a single $8 ESP32-S3 chip processing voice commands entirely on-device. now anyone can build this. here is the full guide: x.com/i/article/2081…
