Tokay Lite: Esp32-s3 Ai Camera That Wakes On Motion

An open-source ESP32-S3 camera board with PIR wake, IR night vision to 10 m and on-board face detection. It sleeps on microamps, runs the model itself and sends results over HTTP or MQTT.

S1-adv: An Openclaw-connected Cardputer Adv

An experimental ESP32-S3 handheld interface with local tools and a bridge to a host-side OpenClaw agent. The device handles keyboard, display and audio; models and optional builds run off-device. Source, architecture and a filmed walkthrough of my own setup are included.

DIY Retro Camera (Afterglow)

Bring back the joy of film: wind it, shoot it, wait for it. Build your own retro camera with a UNIHIKER K10.

Arduino-based Automatic Air Compressor Controller

Build an Arduino-based air compressor controller that automatically maintains tank pressure using an analog pressure sensor and a relay module.

Building A Basketball Hoop Alarm Clock That Actually Gets

A while back, a client came to us with a simple problem: phone alarms don't work. You swipe, you snooze, you go back to sleep.

Make A Morse Practice Recording In Your Browser

Turn a short message into a Morse audio file, then use a decoder to read it back. A simple exercise with no circuit to build.

M5 Timercam X: Wi-fi Camera With Live Web Dashboard

Turn a thumb-sized M5Stack Timer Camera X into a self-hosted network camera: configure Wi-Fi from your phone, watch a live stream.

Therezor/cardputer-ai

Fully offline tiny LLM chatbot on the ESP32-S3 Cardputer ADV - 8M params, Q4 weights baked into the firmware, ~5 tok/s.

Eye Pendant V2

The Eye Pendant is a wearable electronic pendant with a small round display that shows an animated eye. The eye moves around the screen, loo

Fallsena

FallSena detects falls and alerts caretakers within seconds. The wearable device senses a fall the moment it happens and sends an alert straight to a caretaker's phone, ensuring the caretaker is always aware.

All About Ttp223 Capacitive Touch Sensor

Stop using clunky physical buttons for your Arduino projects. Instead, why not use the TTP223 capacitive touch sensor.

Native Linux 7.2.4 On Esp32-s3

Native Linux 7.2.4 running directly on a single ESP32-S3 N16R8. The project includes WiFi, SSH, writable storage, Bash, MicroPython and a custom fork() implementation for NOMMU, using the ESP32-S3 cache MMU to reduce memory-copy overhead during process switches.

Murdrum

Eight voice MIDI drum sample player for Eurorack, 3U/6HP or 1U/20HP.

Ewatch: An Open Esp32-s3 Smartwatch You Program With Ai

A full ESP32-S3 dev board in a watch: 1.69" colour touchscreen, USB-C, WiFi, Bluetooth LE and a 350 mAh battery, with open-source drivers on GitHub. It took me five years and four attempts to build. Now I write most of its firmware by prompting Claude Code with the driver headers.

Shopcam 2000: A Button That Records The Past

A battery ESP32-S3 "That was Awesome" button saves the last sixty seconds from nine cameras at once, over ESP-NOW and the Blue Iris JSON API. I press it after something worth saving happens, and every angle of the minute before lands in it's own directory. Then it runs STT and saves a file for searching later.
