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.

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.

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.

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.

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.

Case Study: Esp32-s3 Smart Curtain Automation Controller

A European window treatments company came to us with a problem. Their motorized curtain line worked fine as a standalone product, but customers kept asking for app control, voice assistant support, and scheduling.

Esp32 Touchscreen Home Automation Control Panel - Esphome

In this tutorial, we will learn how to make a wall-mounted Smart Home Dashboard by using two ESP32 boards

Case Study: Building A Qr Code Attendance System On Arduino

A manufacturing facility in Pune approached us with a frustrating problem.

Wifi Geolocation On The M5stack Core2

Will guide you to build a Wifi Triangulation based Geo Location on the M5Stack Core 2

Wireless Distance Monitoring With Tf-luna Lidar And Xbee

A client came to us with a straightforward-sounding request: they needed to monitor the distance between a moving gantry crane and a storage rack in real time.

Building A Secure Online Prescription & Patient Management A

We recently wrapped up a project that combined two things we love: secure patient data handling and embedded systems.

Diy 3d Printed Led Roulette Wheel | Esp32 C3 Project

Today I am going to show you how I made a "Digital Roulette Wheel" by combining ESP32-C3 with the classic CD4017 CMOS decade counters

Build Your Own Wifi Scanner: Network Detective Tool

Ever wondered what WiFi networks are around you? Here's how to build one with your hands!

Solar-powered Rfid Water Vending Machine Using Esp32 For Off

We’ve built vending machines before, but this one had a twist — no grid connection, no cellular towers nearby, and a budget that ruled out industrial PLCs or proprietary controllers.

Iot Cold Storage Monitoring System Using Matter Protocol

We recently wrapped up a project for a cold storage facility that needed to monitor temperature and humidity across 12 separate chambers.

Smart Security System Using Arduino, Rfid & Pir Sensor

In this project, I'll show how I built a Smart Security System using Arduino, RFID, and a PIR sensor.
