Rather read credible books on engineering or study at an accredited university than reading the junk "advice" on this blog. --- End quote --- Actually I think EEVBlog has the lowest signal-to-noise ratio of any large internet forum I'm aware of. I've gotten plenty of helpful advice here, and perhaps given a bit too. I think the point of the LED-circuit discussion went over your head. Yes, it turns out you can solve it surprisingly accurately compared to Dave's experiment--the one where he went to the trouble of matching the LEDs. Lots of us know the diode equations and their applications--bias compensation in an audio amplifier for example--but I think most would not bother trying to apply it to such a circuit. And, in the end, it turns out that the person who had presented the problem had no intention of anyone using it. The analysis that you had attached to one of your posts, I don't know if it is yours or if you copied it, has an interesting statement. "Engineering students are taught to make reasonable assumptions when there is missing information." Is that really acceptable for 'professional engineers'? Or just for solving academic problems? And as for your statements on registered and professional engineers, there was a debate on on that long back. Every country and sometimes states has their own rules on this, but those certifications are typically required only for certain activities. Except for one hapless Oregon man who the licensing board went after (they lost, eventually) I've not heard of any such requirement for making public comments or YouTube videos. |

It is too bad that the OP is getting nothing from the EEVBlog. I admit that I pay little attention to the videos. While Dave is better than most, I can read much faster than videos present information. This comment is totally independent of the quality of the content though I have noticed no major bloopers in the videos I have observed. If the OP is complaining about the forum also, then I suspect that the finger should point back at himself. I have advanced degrees in engineering, and am retired after a five decade career in the field and find much useful information on the forum. Some theoretical information, but I would agree that texts are usually a better source. But a great deal of specific and practical information about specific devices, instruments, repair techniques and sources. In addition, the caliber of the people involved in the discussions is far higher than typical in other on line venues. People here to make trouble, people who have trouble tying their shoelaces and people who have difficulty dealing with other points of view are relatively rare. Absolutely not useless. |

The vast majority of PE's I've known are civil engineers and structural engineers. |

Dave sells video views, simple as that. If he steps them up to the level of PhDs, the audience shrinks to the point that there is no money in making videos. The videos need to be of value to beginners. I like this one: Yes, I know there are second order effects to consider but the video presents the essence of how to use op amps. There is time later to discuss the fine points. There are a lot of talented people on the forum that keep the conversations on track. That is the main purpose of the forum; help beginners make things that work. I suspect many of these helpful people do indeed have formal education - a lot of it! OP: Your objections are noted. Now go find a more appropriate forum for your more advanced status. |

Never seen anything else than ideal opamp on Electronics II, never seen one at digikey. Uni has its place but it doesn't prepare you for the real world. Good luck. |
