[OVERVIEW]

Personal Projects & Real-World Builds

MTE Solutions Group is operated by Michael Hemmett — someone who loves tinkering with electronics, especially 12V systems, and building complete end-to-end solutions for real problems. What started as hands-on curiosity has grown into the ability to deliver across hardware, web, and mobile.

Every project is practical-first. The focus is always on things that actually work reliably in the real world, not over-engineered concepts. Rapid prototyping, iterative refinement, and shipping systems that hold up under real conditions.

TravelMate — Android App

TravelMate is an Android application built for travel groups — enabling live GPS location sharing, group chat, journey breadcrumb recording, and Bluetooth fridge temperature monitoring. Designed for 4WDs, camper trailers, and off-grid adventures.

The app integrates real-time telemetry, push notifications for fridge alarms, and a clean map interface for tracking your convoy. Built from the ground up with a focus on reliability in remote conditions where connectivity may be limited.

LET'S TALK

ABOUT MICHAEL HEMMETT

Builder · Tinkerer · Problem Solver

[01]

The Background

I'm someone who loves to tinker and play with electronics — especially 12V systems — and to design concepts and solutions that assist myself, family, and friends with practical solar and low-voltage setups.

What started as hands-on interest has grown into a genuine ability to design and deliver complete solutions across hardware, web, and mobile platforms. I'm driven by a passion for building, experimenting, and solving real-world problems through technology.

From custom-built electronic systems to fully integrated web platforms and Android applications, every project gets a practical, problem-solving mindset focused on making things work reliably — not just in theory, but in the field.

[02]

How I Approach Things

I focus on building practical, working solutions rather than over-engineered concepts. The goal is always forward progress — rapid prototyping, testing in real conditions, and systems that can evolve over time.

Whether integrating hardware with software, building custom tools, or developing complete platforms, the priority is simple: make it work, make it reliable, and refine it as needed.

Most builds come from hands-on experience — testing, breaking things, and improving systems under real conditions rather than relying purely on theory. There's no substitute for actually running the hardware and seeing what happens.

[03]

Projects & Scope

Projects range from personal builds through to small-scale business solutions. Many are developed for internal use or specific operational needs, with the potential to expand into broader applications over time.

The common thread is practicality — building things that solve a real problem, used by real people in real conditions. From a solar monitoring dashboard for a camper setup to a full Android app for travel groups, each project pushes the capability forward.

  • Personal electronics builds and off-grid system design
  • Small-scale business tools and automation
  • Mobile applications for specific operational needs
  • Hardware + software integrations that bridge both worlds
  • Ongoing refinement and iteration of existing systems

  • Schematic design and circuit simulation
  • Component selection and sourcing for practical builds
  • PCB layout and prototyping
  • Embedded systems and hardware integration
  • Testing, debugging, and iterative improvement

12V & Off-Grid Systems

A strong focus area — 12V systems for real-world use across camper trailers, 4WDs, vehicles, and boats. These setups are designed to be practical, reliable, and easy to understand and maintain. Systems that just work when you need them out in the field.

  • Dual battery system design and setup
  • DC-DC charging integration and configuration
  • Solar charging panels, controllers, and monitoring
  • Voltage, current, and battery state-of-charge monitoring
  • Custom telemetry and remote monitoring systems
  • Fridge and load management for extended off-grid use

Most builds come from hands-on experience — testing and refining systems in real conditions. The goal is always simple: reliable power when you need it most, whether you're 500km from the nearest town or just in the backyard.

// SOFTWARE
</>

Web Application Development

Building functional web platforms and systems — dashboards, APIs, and custom-built tools designed around specific operational needs rather than generic off-the-shelf solutions. The focus is on web systems that integrate tightly with hardware or data sources.

  • Custom dashboards for monitoring and data visualisation
  • REST APIs and back-end data systems
  • Real-time telemetry displays and alert systems
  • Automation tools and workflow integrations
  • Hosting and deployment for live systems
APK

Android App Development

Building Android applications that tie hardware and data together in a clean mobile experience. Focused on device integration, real-time data, and practical utility — not generic apps, but tools built for a specific purpose and user.

  • Native Android development (Kotlin)
  • Bluetooth BLE device integration
  • GPS and location-based features
  • Real-time server communication and push notifications
  • Offline-capable design for remote environments
  • Background services and foreground notifications
// AUTOMATION & TELEMETRY

Telemetry, Automation & Data Systems

Tying sensors, hardware, and software together into systems that collect, transmit, and act on data automatically. From simple voltage monitoring to multi-channel telemetry with alerting and logging — built to run reliably in the background without attention.

  • Battery monitoring — voltage, current, state-of-charge
  • Temperature sensing and threshold alerting
  • Remote monitoring via web dashboards or mobile apps
  • Journey and route logging (GPS breadcrumbs)
  • Scheduled data collection and server-side storage
  • Push notification alerting for threshold events

PRIVACY POLICY

TravelMate — MTE Solutions Group

EFFECTIVE DATE: 11 MARCH 2026  ·  LAST UPDATED: 11 MARCH 2026
GOVERNING LAW: PRIVACY ACT 1988 (CTH) · AUSTRALIAN PRIVACY PRINCIPLES

1. OVERVIEW

MTE Solutions ('we', 'us', 'our') operates the TravelMate mobile application ('the App'). This Privacy Policy explains how we collect, use, disclose and protect your personal information in accordance with the Privacy Act 1988 (Cth), the Australian Privacy Principles (APPs), and applicable Western Australian law.

By using TravelMate you agree to the collection and use of your information as described in this Policy. If you do not agree, please do not use the App.
