Today I called Steven Gibbs the inventor of the HDR. My HDR is old from circa 2001 and I want to get a new model of Steven Gibbs HDR. My old HDR is a bit travel torn. The new model has different components in the box as well as a flat HDR caduceus coil. I believe the electromagnet is the same in both models. They both use 21 gauge magnet wire.

I am looking forward to getting a new unit.

Why did Steven Gibbs create a radionics device?

According to Steven Gibbs in 1981 he received a letter from his future self on how to create a time machine. This led Steven Gibbs to create the Sonic Resonator, later in 1985 he would imporove on the original device to create the Hyper Dimensional Resonator. 

This radionics machine was now stable enough that Steven Gibbs began to make it available to people.

Steven Gibbs says that in the last twenty years he has sold about seven hundred time machines. All of them based on drawings he received in 1981.
