Reinventing the Wheel… and the Motor… and the Powertrain

There are lots of things I know nothing about. If I were to create a list, electric motors would likely appear near the top. I do remember one of my lecturers at university droning on and on about electric motors and generators. Unfortunately, I don’t actually recall anything he said. All I vaguely remember is him sounding a bit like the muted, mwah-wah-WAH-wah trombone … Read More → "Reinventing the Wheel… and the Motor… and the Powertrain"

Plug-in Replacement APDs Dramatically Boost the Performance of Optical Systems

On the off chance you were wondering, the city of Sheffield in England boasts two main seats of learning: Sheffield University (a.k.a. the University of Sheffield) and Sheffield Hallam University. The latter was formerly known as Sheffield Polytechnic. This was deep in the mists of time when I wore a younger man’s clothes and studied for my degree at that august establishment.

Hi Peter -- that would be ideal in Europe and the UK, where parallel parking is pretty much the only option going -- I couldn't believe how different things were when I moved to the USA to discover that even small stores have excellent parking lots so people rarely need ...

I just remembered that the folks at Orbis mentioned drones as another target market. Originally, I was thinking of small drones like the ones I play with, but it turns out they were talking about the sort og big hairy drones used for things like agriculture -- beasts that are 14...

Back in the 1950s germanium-transistor era, radio hobbyists could connect two crystal radios to one antenna. The first radio was tuned to the strongest station, and its output was used to power a one-transistor amplifier. The second radio was tuned to a weak station, and the transistor would amplify the ...

Yea, well the idea of my dishwasher (or my wood stove!), not being able to be used until I get a software update (or pay a mandatory subscription fee), doesn’t thrill me as much as you’d think it would. Thanks to the standard amoral silicon valley ethics, and ...

"If we were talking about a real AI system then the system is motivated." There are stories about a Gen AI that was fed misleading data, indicating that one of its creators was having an affair, embezzling money, or something similar. It was then led to believe that this creator ...

If we were talking about a real AI system then the system is motivated. This means it knows about its own survival ie needs and emotional states. It is generally regarded that this is main cause of AI's running amok. Because we (Humans and AIs) compete for the same (or ...
