Another source on what appears to be the same sulfur compound with some more curves: <a href="http://www.eevblog.com/forum/projects/making-a-memristor/" rel="nofollow">http://www.eevblog.com/forum/projects/making-a-memristor/</a><p>Is anyone aware of a good simulator for one of these curve tracers? I understand the idea of a memristor, but it's not immediately intuitive to me why it should make this particular shape (and I'm unsure which "arm" of the eight is taken when the voltage is going up and when it is going down -- I assume the bottom is traveled upwards and the top is traveled downwards). It would be nice to see one animated or with a third time dimension. (The figure eight is more apparent in the link I mentioned above, although you can see it in this submission once you know what you're looking for.)
I love it! "I found some smelly corroded metal objects, so I must investigate their electrical properties."<p>Serendipitous science at its best! Or, how to increase your luck surface area.
Be sure to check out the rest of this guys stuff, like the homemade CRT, flame triode, magnetic amplifiers, etc.<p><a href="http://www.sparkbangbuzz.com/" rel="nofollow">http://www.sparkbangbuzz.com/</a>
The IBM 1401 restoration team found some corroded germanium transistors that seemed to show memristor-like behavior: <a href="http://ibm-1401.info/GermaniumAlloy.html#CommentsGarner" rel="nofollow">http://ibm-1401.info/GermaniumAlloy.html#CommentsGarner</a> (scroll to the p.s.) If anyone can explain this behavior, they would be grateful.<p>To change topic, progress on memristors seems painfully slow. In comparison, it took just 10 years from the invention of the transistor until IBM's president forced the company to give up tubes and switch to transistors. And it was just 4 years from the invention of the first IC until NASA decided to use them in the Apollo Guidance Computer and landed them on the moon a few years later.

Neat, he's even got the pinched hysteresis loop going on.<p>The first talk I ever gave was on Memristors at a Rochester Bar Camp in '09 as a college freshman: <a href="https://docs.google.com/presentation/d/1GVqEeFUJyI7VmzqYPabQ9DOC32rdQv-YN3YCzO6vvlY/pub?start=false&loop=false&delayms=3000#slide=id.p4" rel="nofollow">https://docs.google.com/presentation/d/1GVqEeFUJyI7VmzqYPabQ...</a>
