This is a Hyper Dimensional Resonator, also known as an HDR. Invented by one Steven Gibbs in 1985, this device is said to manipulate time and space, allowing its user to embark on strange out-of-body experiences (OBEs).

Oh, but the HDR possesses many other unique qualities, as well.

It may produce fog, or rain. It may change the way your mind functions, and how you perceive the universe. And, most intriguingly of all, if you successfully locate an interdimensional gateway, or vortex (at just the right time, of course), you can even use the device to astrally travel through time.

Yes, you heard right: it is a time machine.

It also may or may not attract cats.

How Does It “Work?”

It’s simple, really.

The user must first place a quartz crystal into the “witness well,” which augments the frequency of the HDR, thus allowing time travel to occur. Then, the user must rub the rubbing plate while concentrating on the time and place he or she would like to travel.

When turned on, a Tensor coil within the Hyper Dimensional Resonator produces scalar waves that warp time around the device, generating an electromagnetic field and disrupting the usual flow of time. And off you go.

Like I said, simple.

Given the relative simplicity of the hardware, many have also attempted to build HDRs at home. That’s right: you, too, can unlock the power of time travel by soldering six rectifier diodes in a circle inside a box that looks about as complicated as an Atari 2600.

Has Anyone Traveled Through Time With It?

Many claim to have successfully traveled through time using an HDR, yes. Others have reported bizarre OBEs and other phenomena.

In 2004, one brave soul in particular risked his life in an unsuccessful attempt to voyage back to the year 1982.

Here is the shocking footage, caught on camera:

So be careful out there, fellow chrononauts!

And don’t forget the crystals!
