Great to see this discussion. My son displayed a science project on negative differential resistance 21 years ago. Had quite a few electrical engineers passing by with "the low brow" look. His device involved carbon fibers arranged in a cross shape placed inside of a cement mixture and compressed to ~8,000 psi during the cure stage (following the example of some published research).
- NooneAtAll3 3mo agowhat does low brow mean?
- signa11 3mo agoumm `surprised scrutiny and skepticism` perhaps ?
- tdeck 3mo agoThere are apparently some very simple ways to achieve negative resistance in a home lab. For example http://sparkbangbuzz.com/zinc-40-meter-xmtr/zinc-40-meter-xmtr.htm http://sparkbangbuzz.com/zinc-40-meter-xmtr/zinc-40-meter-xm...
