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

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.

Building A High-temperature Monitoring System With Arduino U

This project uses an Arduino UNO and MAX6675 thermocouple module to accurately measure high temperatures in real time, making it suitable for industrial heating systems, furnaces, ovens, and laboratory monitoring applications.

Arduino Gps Boundary Detection System With Instant Sms Notif

A smart Arduino GPS tracking solution that detects boundary violations and instantly sends SMS notifications for real-time monitoring and security.

Rotating Led Sphere – A Rp2040 Pov Display Step By Step

Inspired by the Las Vegas Sphere, this project brings the concept to desktop scale: a spherical POV LED display powered by an RP2040. It plays videos and animations from an SD card, runs wirelessly, and can be controlled via Wi-Fi. A key goal was to achieve stunning visuals using as few components as possible. Fully open source.
