About

I work on embedded systems and electronics, with an emphasis on the point where hardware and software meet: microcontroller firmware, analog and digital circuit design, and the control logic that connects sensing to actuation.

My approach is to build complete systems rather than isolated components, and to document what fails as carefully as what works. Each project is developed in iterations, where the problems found in one revision define the requirements for the next.

Projects

Rescue Robot Car A remote-operated rescue robot with differential drive, built around an STM32F407 for motion control and a pair of ESP32 modules for the wireless link. Radio and real-time motor control are kept on separate microcontrollers so that a communication fault cannot delay a PWM update.

Density-Based Traffic Light System A traffic light controller that grants priority to the road with more waiting vehicles, implemented entirely in discrete logic — counters, a magnitude comparator, timers and flip-flops, with no microcontroller or firmware involved.

Additional Work

Alongside the engineering projects, I maintain a self-hosted Raspberry Pi and Linux environment covering networking, containerised services, monitoring and MQTT-based IoT integration. The related repositories are published on this profile.

Pinned Loading

  1. Density-Traffic-Light Density-Traffic-Light Public

    Density-based traffic light built entirely from discrete logic ICs — counters, a comparator, flip-flops and 555 timers decide which road gets green. No microcontroller, no firmware. Proteus simulat…

  2. rescue-robot-car rescue-robot-car Public

    Remote-operated rescue robot built prototype by prototype — STM32F407 motion control, dual ESP32 Bluetooth link, hand-built 3S2P 18650 pack. Radio and motor control deliberately on separate MCUs.

    C

  3. metehantech-homelab metehantech-homelab Public

    Two-node home lab infrastructure as code — redundant AdGuard DNS with parity and failover tooling, Mosquitto MQTT, and Home Assistant, all reproducible from Compose and scripts.

    Python

  4. metehantech-smart-home metehantech-smart-home Public

    Home Assistant automation generated from Python, plus a no-listener file bridge for infrastructure HA cannot see. Manual control always wins; the camera is off while you are home.

    Python

  5. metehantech-status metehantech-status Public

    Self-hosted control centre for a two-node home lab — health metrics, alerting with a single delivery path, verified backups, and a resilience harness that tries to break them.
