Projects
A selection of electronics design, embedded systems, and industrial automation projects we've delivered for our clients.
Isolated M-Bus to TTL Signal Converter for Smart Metering
An industrial-grade interface board with full galvanic isolation that converts the M-Bus meter protocol to UART/TTL, enabling smart reading of water, gas, and electricity meters in IoT systems.
Predictive Maintenance System — ESP32 Edge Node + AI Anomaly-Detection Backend
A predictive-maintenance system: an on-machine ESP32 hardware node plus a server-side ML engine with a 5-algorithm PyOD core and root-cause analysis for real-time anomaly detection.
Smart Splice Watch — Conveyor Belt Vulcanization Controller
An STM32F4-based precision control and data-logging system for the hot vulcanization (splicing) of conveyor belts in mining, cement, and steel, with dual independent PID loops and a verifiable digital quality certificate for every splice.
AI-Powered 3D Delta Robot for Pick & Place
A high-speed delta robot integrated with a deep-learning vision system (Intel RealSense + TensorFlow/Keras) for autonomous, fixture-free picking of randomly oriented objects on the production line.
Pharma-Grade IoT Data Logger for Cold-Chain Compliance
An ESP32 + DHT22 temperature and humidity data logger with OLED display, custom 3D-printed enclosure, and a cloud dashboard with interactive charts for pharmaceutical storage compliance.
Autonomous STM32 Field Data Logger — Gas Pipeline Monitoring
A self-contained, battery-powered STM32 data-acquisition system for monitoring critical parameters on remote gas pipelines, with 7-day autonomous operation and ultra-low power.
TouchGFX on External QSPI Flash — STM32H7B0
Booting and running a full TouchGFX UI from external QSPI flash on the STM32H7B0, a three-part firmware-engineering challenge with a custom bootloader and a dedicated external loader.
Smart Industrial Temperature Controller — Dual-Relay Architecture
A production-ready, STM8-based single-loop industrial temperature controller with a DS18B20 digital sensor, dual relay outputs, and EEPROM storage, a drop-in replacement for expensive analog controllers.
Full-Featured Low-Cost IoT Security System with ESP32-CAM
A comprehensive, affordable ESP32-CAM-based security system integrating vision, PIR motion detection, gas sensing, and cloud alerting into a single device.
ESP32-Based Industrial Saffron Processing Controller
A specialized ESP32-based process controller for saffron processing machinery, with a dual-board architecture (control/power separation), touch display, and OTA updates.
Electronics Catalyst — Remote Arduino Learning Platform
An online platform that lets users test their code on real Arduino hardware remotely, with Hardware-in-the-Loop, virtual wiring, and environmental simulation.
NELSCO Industrial Relay Controller — Drying System
A PCB-level relay controller for an industrial drying system, one of the first designs to reach volume production.
