1uF Capacitors

[PRR]

My fellow New Englanders most certainly just felt that earth quake.

From friends near-enuff to the epicenter:

Holy $hit!  Did we ever get an earth quake.  I was sitting at the kitchen table, talking to Bill, and Man o Man!  4.7 on the scale.
Windows rattled, pictures came off the wall, pots and pans jingling.  It sure was something.  Bill says "Rock quarry?"  I said "No, that's not the Quarry............ its.... its... an ....Earthquake!  Of course the Dogs went nuts.

We just had a 4.0 aftershock! I was on the toilet...

Getting back to capacitors..
Why aren't Non Polarized aka BP caps used or specified more often in effect circuits?

[GibsonGM]

I think size is a consideration (NP are larger?), and cost.  The 'big dogs' trim every penny they can, and NP costs more per unit...I cannot think of any place you can't use a NP in place of polarized (maybe someone else can?).

For the EA Tremolo that calls of four 1uF caps I use BP.
Because I was unsure of which way + goes and film was to big, R.G. gives a good Mouser ref for next time.
Got 20 on Amzon for $8.
They are the same size as polarized. Small(ish).

[GibsonGM]

I'd use 'em, no questions asked.  Convenient...and you really aren't supposed to use polarized caps with AC. Y'know - since it's always changing     That hasn't hurt me any - I only think about DC voltages when using them - but still, it's just 'not right'.

What I want to see is star "light" in front of the moon.
The light that is bent by the gravity of the sun.
Ie the experiment long ago in Russia to prove gravity bends light.

Hi, that would be ace, but gravity lenses don't quite work like that.  The light is bent as per a convex lens, so that something that would otherwise be behind the sun/moon would appear further out sideways, not in front.  The effect is too small to detect with the naked eye sadly.
