Quest for Fire (or Radiant Spike)

BTW, there are enough people here that build and do not think.

Thanks Ernst, I'll certainly remember that quote!

Happy New Year

Not sure if this will help - from Scherz & Monk's Practical Electronics for Inventors, Third Edition, p. 154. There's actually a mistake in the text on this page, I think (due to two contradictory statements about inductance, capacitance and frequency), but I'll go with the one that lines up with what the page's graphics illustrate:

"When a voltage changes due to ac current passing through a coil, the effect is that of many small capacitors acting in parallel with the inductance of the coil."...

"Inductors exhibit distributed capacitance... Below resonance, the reactance is inductive... Above resonance, the reactance is capacitive and increases with frequency."

In other words, at self-resonant frequency, the coil's impedance is at its highest. As frequency increases above that of self-resonance, the impedance of an inductor drops, and its capacitance rises.

what's the best and worst thing that happened in your day!

I thought this was important enough to share.

The best thing that happened today is that I got to cook breakfast for my Mother this morning.

The worst thing is that I dropped all the eggs and salvaged one for Mother. The other six made a huge mess. As I cleaned them up with paper towels and a large bowl; I noticed that the corner of my heavy Terry cloth robe was helping me clean up egg goo. dang it!

Second Best Thing Today

The second best thing that happened today is that I just filled my car at Ingles for $1.69 a gallon.

Mother Nature just prevented you from preparing 7 eggs for your mother.
That is a good thing, cholesterol wise.

Then you got the poor man's egg-goo-on-your-heavy-Terry-cloth-robe-corner-discount at Ingles.
