From Ghost Radars to SpecTracers: The Evolution of my Paranormal Mapping Tech

When I first launched my ghost radar devices back in 2023, they were simple, standalone tools built for curious minds – like mine – that wanted to push the boundaries of paranormal investigation. But in just a few short years, what started as a Bluetooth-connected experiment has transformed into a modular, connected ecosystem powered by the ParaLink Mesh app.

Here’s a behind-the-scenes look at how we got from there to here – and where things are heading next.

📡 The Original Ghost Radar (2023)

The very first Ghost Radar was powered by an Arduino Mega. It used a ToF (Time-of-Flight) sensor to scan in a sweeping arc, detecting changes in depth and movement in the environment. These early radars were rudimentary but effective – and sparked a wave of interest.

Each Ghost Radar connected to a mobile app via Bluetooth, but there were key limitations:

• It required one phone per radar, people wanted multiple Ghost Radars, but didn’t have the phones for each 1.
• There was no internet connection or SD card storage
• Firmware couldn’t be updated, as there was no OTA (Over-the-Air) system in place
• There was no screen on the device, so all data had to be interpreted through the app
• No built-in battery, they were power hungry and had to be powered via a power bank and USB cable

Still, it was a massive step forward in giving ghost hunters and investigators a physical, scannable presence detector.

Before the original Ghost Radar was ever released, I spent several months deep in testing and prototyping. IF you followed me on my social media, you would have seen the photo’s and videos I uploaded to show you all. I tried out a variety of Arduino boards to find the right balance of performance, power consumption, and compatibility with the sensors I needed.

Alongside the electronics, I was designing and 3D printing custom cases to house the components – tweaking dimensions, airflow, and aesthetics until everything fit just right.

One of the biggest challenges was portability. In the early days, the Ghost Radar would be mounted to a tripod, but I had to lay the phone and power bank on the floor during investigations, which wasn’t ideal. So I designed a tripod-mountable tray system that could hold all three securely, making setup much more practical and professional.

That phase of trial-and-error was critical in shaping the device into something both reliable and usable in real-world environments.

💡 The Birth of the SpecTracer (2025)

By 2025, I knew it was time to level up.

That’s when the SpecTracer was born.

Built around the M5Stack Core Basic, these devices brought huge improvements:

• A built-in screen for standalone operation and visual feedback
• A built-in battery, giving around 5 hours of use from a full charge
• Wi-Fi connectivity for real-time control and updates
• An SD card slot for data logging and offline investigations
• Modular architecture, allowing add-ons and future expansion
• Full support for OTA firmware updates, making it easy to roll out new features

Unlike the original Ghost Radar, a SpecTracer doesn’t need a phone to function – but if you do connect it, you unlock even more capabilities.

🧠 Enter the ParaLink Mesh App (2025)

The real game-changer came with the release of the ParaLink Mesh app.

A huge update to my original Ghost Radar App. No more one-phone-per-device. No more isolated readings. The ParaLink Mesh app allows multiple SpecTracers to be connected to a single mobile device via the phones Wi-Fi hotspot. From one interface, you can:

• Monitor and control each SpecTracer individually
• Visualise synchronised readings from multiple rooms or areas
• Activate remote functions like scan angles, data logging, and sensor triggers
• Built-in screen recording functionality via your phone / tablet
• View a mesh-style map of activity, helping track potential anomalies across a location

The system now behaves like a coordinated sensor network, offering powerful tools previously only found in industrial or military-grade tracking systems.

🔮 What’s Next: Expanding the ParaLink Ecosystem

SpecTracers are just the beginning.

The ParaLink Mesh app is designed to support more than just SpecTracers. Soon, it will become the command centre for a range of purpose-built investigation tools.

There’s much more in development – some of which I haven’t revealed to anyone yet. But trust me, they’re unlike anything else out there.

👻 Where We Are Now

The current SpecTracer + ParaLink Mesh ecosystem is the most advanced I’ve ever created. It’s built for serious investigators, content creators, and curious minds alike. It’s modular, scalable, and future-proof.

Key features now include:

• Mobile App support (Android Only)
• OTA firmware updates for all devices
• Real-time multi-device tracking
• Local SD logging
• Screen recording through the app
• Expandable platform for future devices
