  • If engineers ruled the world…
  • As I recall, ten years ago the entire Chinese cabinet had science or engineering degrees, and China has not been doing so badly. In the UK and USA, being a politician is one well-paid and powerful occupation you need NO qualifications for. To run a country you might think the least would be an MBA, along with a degree requiring logical joined-up evidence-based thinking, like science or engineering.

  • For error analysis, it’s hip to be squared
  • I wish you would just publish this kind of article on a single page! It seems to take ages to load the next page, so I do something else, and often lose the place. Why do you break articles up? To give readers more time to read the ads?

  • That 60W-equivalent LED: What you don’t know, and what no one will tell you…
  • Yes, I found this two days ago with an outdoor LED 10w spotlight. The switch light caused the LED to flash for a small fraction I of a second very 5 or 6 seconds. This switch had a wire to the illuminating light which I could change from load to neutral, so it is on all the time - no real disadvantage compared to having the illumination on only when the main light is off. Oh, and you do need a neutral wire brought to the switch.

  • Circuit gates pulse train without truncating
  • This function is the same as the old TTL SN74120 Pulse Synchroniser, though the detailed circuit is different. Interesting that the same idea comes up 40 years later.
