Case Study: Retrofitting Intelligence: Building A Smart Hvac

We recently wrapped up a project that felt like a throwback to classic embedded engineering. A client came to us with a common problem: they had a commercial office space with a legacy HVAC system. It was a workhorse—reliable, powerful—but dumb. It ran on a fixed schedule, ignored occupancy, and treated the entire 5,000 sq ft fl

Wifi Geolocation On The M5stack Core2

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

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

Gps Tracker Using Heltec Wifi Lora 32 V4 And Reyax Rys352a G

Build a browser-based GPS tracker using the Heltec WiFi LoRa 32 V4 and REYAX RYS352A Multi-GNSS module. This project visualizes real-time location and travelled routes on OpenStreetMap while hosting the tracking interface directly on the ESP32—no third-party cloud platform required.
