It is hard to put into words how so many people "out there" can print things, have people read them, and they are so worded that the average person is probably reading this as "the truth".
> but it’s rather difficult to build a good analog oscillator from scratch. The most common category of oscillators you can find on the internet are circuits that simply don’t work. This is followed by approaches that require exotic components, such as center-tapped inductors or incandescent lightbulbs.
It is not hard to build a good analog oscillator from scratch, we have been doing this for decades. Secondly, while an incandescent _might_ be considered exotic, and completely unnecessary for an oscillator, a center tapped inductor is totally not exotic, and also, not really necessary for an oscillator.
As others have noted, it is simple to build a really good analog oscillator. This article is blah, and "meh" at best.
