Heh. Cheap trick. Though I've been thinking of getting a Zeta MIDI-fiddle

If we're talking festivals and jam sessions, the list gets pretty long. GetI play flute and a bit of pipes, but the best name I can drop is that
I played with Cathal McConnel at a festival many years ago! (Oh, and I
vaguely knew old Des Donnelly- Dezi's uncle- before he died)

The problem is caused by the way capacitor operates. When you use a large
capacitor with a bridge rec. on AC 120V line, the capacitor will charge to
171V DC, which is the peak votlage of sinusoidal 120V AC. Except when the AC
waveform is at the peak, the load depends on capacitor charge to operate. The
charge depletes as the AC voltage sways from the peak. If you let it drop to
165V, the capacitor will not start charging until mains voltage goes up to
165V. At 165V, it abrubtly loads the mains and charges up from there to peak.

You can also use calculated series inductors on input side to correct power
factor with a fixed load. The property of inductor slows down the current rise,
lowers the harmonic distortions and increases power factor.

one of the best places to start, because it helps you ask more questions
and seek more answers is by going to radio shack and getting their new
book "Getting started in electronics" that encompasses all of their old
Forest Mimms mini engineers notebooks. They have lot's of cool little
projects and off some good beginning info. Radio shack will also be a
source for some entry level components like 1/4 watt and 1/2 watt resistor
assortments, electrolytic capacitor assortments disc capacitor assortments
and LEDs and what not. I like to build things like small projects and try
to find out how they work along the way. Get a breadboard or two also.
As for the previous fellow with the hammer analogy, I worked with a hammer
for 20+ years, now because of a start like the one I described above I am
the Webmaster, Network Admin. and advertising graphics artist for our
company.
I write all of our instructions and do all of our technical illustrations,
manage our product labeling system and they are paying for my electronics
education (CIE course while I work), I am starting to teaching myself to
write assembly for PIC microcontrollers (which most of our products use).
At this time I have put all aside for our second in house video (I am the
technical editor) on a video editing system that I built. It is an
instructional
video for all of our testers.
So I say grab on and have fun, keep asking questions and don't feel like
any question is a stupid question.
