One might argue that all the transistors are created simultaneously in a single processing sequence, and that the chip is, technically, a single component. |

Like most people, Arfa doesn't like high-K lighting. I switched to 5000K CFLs, and though it took a couple of weeks to adjust, I much prefer light that more-closely resembles daylight, and is subjectively brighter. |

Are you any relation to Joshua Speed? Arfa is an intelligent and knowledgeable person. You do not come off as very bright (joke intended) making such a broad attack. |

In general its also a tested component. so it works to spec or it doesn't. *Failure* of a system that worked to start with implies change over time: The relevant point is what changes happen to circuits over time and what law if any, they follow. -- Everything you read in newspapers is absolutely true, except for the rare story of which you happen to have first-hand knowledge. – Erwin Knoll |

One might argue that is the case for the 100-component circuit referred to in the EE Times article. I simply do not know what goes on in the making of "an LED plus its associated circuitry". Is it made as one,two or 101 components? -- Rod |

I too prefer higher K lamps - though probably 4200 to 4500 rather than 5000. I get the feeling that the 2700 ones started out as OK LEDs but someone adjusted it until it was a yellow as a candle. Also want the best possible CRI. -- Rod |

Phil It's the lack of pliabililty. They call it a pinch roller because it pinches the tape. A hard rubber puck is useless. The exact dimension isn't critical as long as the bearings fit and the plunger goes far enough. |

Maybe, I always had a bench setup with voltmeter, scope, sig gen, power supplies, and parts. Showed him ohms law, and verified it. He was ahead of me in math, so it was a breeze, when I needed help I ask him. We once made an electric motor. As a project I suggested we build an electric go kart. We did, but dad did most of the work, but I did run through motor, axle ratio, tire circumference, speed calcs, and he understood. he and the neighbor kids had fun. I will say from the start both kids new they were going to college, my daughter graduated H.S. 4th out of a 430 class. Somewhere around 10th or 11th grade, I figured out my son was probably smarter than my daughter, he just didn't do anymore work than he had to. His grades got him into a good university but he didn't work at it. Now I think it's just video games and laziness that have brought him to a halt.
