Hello, Does anyone know of a science forum that deals with far out, controversial theories & ideas? This would be similar to the science fiction forum here at PF but may even be more outlandish, however postings would receive serious consideration. I have made some simple animations that I...

The first articles I came across all included either platinum or graphene as part of the method to produce spin waves . I now have found out there are at least several other, if not many materials to use.

dlgoff I wish I could find something like that. What I am going to try is to connect a platinum strip to a magnet, then when current is applied to the strip a spin wave comes out the other end of the magnet. A platinum ingot costs a huge amount of money, but a platinum strip is not so high of...

Hello, I have found the technology of spintronics very interesting with a great potential for the (hopefully near) future & I am desiring to experiment with spin waves. I am sure there are several ways to create a spin wave or current, one of which involves placing a platinum strip at the end...

I always obtain such good responses when I post questions on the forums. So to further expand the discussion I had learned that Tesla had generated massive amplification by using quarter (sine?) waves within the secondary coils (of the Tesla coil). Why is this? How could something as mundane as...

It seems we are not as far along with meta materials a I thought we were, which is a disappointment. Any way check out my new posting about Tesla power transmission. Joe L.

Several weeks ago I viewed a PBS program on Tesla - which is always interesting, & I learn new information every time I read or view a program about Tesla. Here is a question that is some what of a mystery - was Tesla trying to transmit power through the ionosphere, the regular (lower)...

Generally a 10K sine wave. But the range could be from 10 to a 2M sine wave.

Hello, Around 18 months ago I did a search on buying mete materials & came up with numerous results. This time I searched & found nothing. So I am posting this to find out where (on the internet) I could purchase meta materials. I am searching for a meta material 3 to 4 inches in diameter with...

Almost always 100K.

Correction: Please note I have a good function generator.

Hello, I need to find out how to generate a standing sine wave, or a quarter sine wave. I had no trouble finding out how to create a full or half wave rectifier, but very little generating a quarter wave, & that info mostly dealt with sound waves. I am doing this for experimental purposes...

I accomplished creating this circuit using resistors & a branch wire. I still get some ac leakage in the central (DC) portion but believe this could be alleviated by a filter. Just thought I would provide an update.

To respond to some comments - I am 58 with 5 years of college. When I saw Westworld in 1974 I became a firm believer that robots would some day become widely used & manufactured. Despite the violent content of WW I also believe that robots will instead greatly help mankind. I have a preliminary...

When I have some extra time I try to plan for creating an applications oriented robotics company. Not only have I searched for an advanced processor, it is even more important to find a functioning robotic arm. About the only arm I have found are prosthetic arms - which might be adapted for...
