1) What is an HDR?
The Hyper Dimensional Resonator (HDR) is a device created by inventor Steven L. Gibbs using Radio Shack parts. Here is an HDR parts list. Perhaps you can build an HDR. I have taken the HDR apart it is an electromagnet.
2) When was the HDR invented?
The first HDR device was created in 1985. It was based on a prior prototype machine called the sonic resonator invented in 1981.
3) Where was the HDR first produced?
In Clearwater, Nebraska on Steven Gibbs cattle farm. The inventor had a workshop in his basement full of tools. It is here that the Hyper Dimensional Resonator was born.
4) Why did he build it?
According to inventor Steven Gibbs, he got a letter from his future self with instructions on how to build a time machine. He was so amazed that he had to try it.
5) How does the HDR work?
Steven Gibbs says that his invention, the Hyper Dimensional Resonator works on the basis of resonance. It uses resonance to distort time. I use the HDR for astral time travel.
