OUR WORK

A showcase of precision-built embedded systems

Rolling Robot
ESP32 · OpenAI · Web Portal
Based on the open-source ESP-ROLL project (ESP32 SoC), extended with an OpenAI Q&A feature that performs visual question-answering from the onboard camera feed. Users can switch between standard and AI modes via a web portal.
Rolling Robot
pH Meter
STM32WB · BLE · Medical
A medical-grade device built on STM32WB that measures the pH and temperature of a fluid. On every measurement, data is stored locally and can be viewed on the onboard display. It has a custom protocol developed over BLE to communicate with a smartphone. The user interacts with the device via physical buttons. OTA updates to the device can be performed over BLE.
pH Meter
Balena IoT Logger
Raspberry Pi · BalenaOS · Python
A Raspberry Pi running BalenaOS hosts a Python script as a containerised service. When a physical switch is closed, the script logs a message to the Balena Cloud, which can be monitored in real time from the Balena dashboard.
Balena IoT Logger
Cold Chain Data Logger
ESP32 · WiFi · BLE · Cold Chain
IoT and offline data loggers built on various ESP32 SoCs for cold chain monitoring — warehouses, pharmaceutical shipping and beyond. Devices measure temperature and humidity with high accuracy and display live stats on an onboard screen. IoT variants connect over WiFi and BLE to log data to a cloud portal, with OTA updates delivered securely over HTTPS. Offline variants are fully self-contained — generating detailed CSV and PDF reports at the end of each trip. Both variants are configurable over USB.
Cold Chain Data Logger
Bluetooth Device Adaptor
ESP32 · BLE · HID · USB
A device that gives BLE capabilities to any wired keyboard or mouse. Built on ESP32, it connects to any BLE host regardless of OS. Features include battery percentage reporting to the host device and LED-based indications for various events.
Bluetooth Device Adaptor
Smart Helmet
Arduino UNO · 433MHz RF · Safety
A helmet that replicates left, right and stop indicators in sync with the motorcycle. LED indications are in the direct line-of-sight of riders behind and oncoming traffic, giving additional protection. Built on Arduino UNO with 433MHz RF communication for seamless wireless sync with the vehicle.
