VIDEO: Aussie inventor captures 'waving ghost' using Xbox camera

We don't want to alarm you, but your humble Xbox could be a ghost detection machine.

If this clip is anything to go by, with a few modifications to the gaming console you could be interacting with Casper and Co.

Aussie electrical engineer Graham Lewis reckons he captured the ghost of a little boy called Oliver when he was testing out his paranormal activity equipment at the Quarantine Station in North Head, Sydney.

A follower of the paranormal investigation program Ghost Adventures, he saw the technology similar to the Xbox Kinect SLS camera being used on the show and found there was nothing similar available in Australia.

So he just made it himself.

The Camden local explains how he took the Xbox product and harnessed infra-red technology and motion sensors  to create his own ghost-spotting camera.

"The unit itself puts out an imaginary laser gird and looks at light returning," he told Pickle.

"What the software does is manipulate the light and look for human figures - it'll put a stick figure on top of me to denote that I'm human.

"What happens with the software, is that you'll get a stick figure and there's no human being there.

"I've proved it time and time again and it seems to be connected to paranormal activity.

"It is extremely interesting."

Interesting indeed.

Lewis' use of the technology is starting to turn him into a bit of a celebrity, appearing in his local newspaper, The Camden Narellan Advertiser and ABC online.

Footage published by the ABC shows a miniature stick figure appearing to wave.

As Lewis explained to journo Sean O'Brien, he found out the stick figure's identify via his medium friend Libby.

Oliver was apparently the son of a worker at the station.

It's right about now that we're going to mention that Lewis was once a staunch sceptic of all things paranormal.

The electrical engineer and inventor was much more interested in science and technology than ghost stories.

But after losing his father, Lewis had an experience that made him question his scepticism – it was like a dream, but more realistic.

"It felt like I was wide awake," he said.

"That sparked my interest.

"[After this] I went down to Port Arthur I got a picture I can't explain.

"It was a sunny day, a nice day and I took a photo of my then wife.

"There was a misty apparition next to her and that caught my interest."

That was enough to send Lewis down a rabbit hole of researching paranormal activity, but through the lens of technology.

After discovering most of the tools ghost hunters were using were "just crappy… really terrible" he decided to make his own.

He found himself out of work for the past four months, and in that time has built up an impressive backlog of paranormal tech products, building his own software and manufacturing pieces using a 3D printer in the shed in his backyard.

And what started out as a hobby has now turned into a business.

Lewis sells his products through his website, the bulk of which was the result of a flurry or work in the past four months.

He's built his own powerful night vision camera and something he calls a Vortex Direction Finder, which looks for static energy.

"It's associated with seeing a ghost… static energy hairs back of your neck stand up.

"It pulses back and forward looking Ghost Busters, my wife reaction reckons."

Now, Lewis is gearing up for a paranormal expo in September.

After that event, he'll be focusing on inventing new equipment, such as temperature sensors and fear detectors that measure brainwaves… in case you needed to put an exact figure to how much you were freaking out on a ghost hunt.
