Who's the troll now, YOU COCKSUCKING REJECT?

Anybody know why the "Deacticated" the Communications Units Group on
Google?

I have developed a binary circuit using ultiboard and how can i
generate Gerber files and native cad file in ASCII. from the ultiboard
program or the Gerbtool program.
what is native cad file in ascii mean?

The DC component losses from I^2 * R end up as heat in a choke. I've
received some mixed signals about the AC reactance component of the
impedance of the choke. One theory, is the energy in the reactance is
simply phase shifted, and returned to the circuit out of phase, and

It's impossible http://www.kevinkatovic.com/ - 10 years I have been
trying to get a payday like all these so called successful online
marketers but its so bad now no one ever gets paid.  After trying
again and again with multiple failures the only thing that makes money

It's still the wild west out in info land.

I see this term in specs for UPS's. Wikipedia describes it as a ratio of RMS
to peak voltage.
That doesn't "grok" for me.
Help me understand what it means re. a UPS whose output is spec'd to be sine

You kept saying "I'm uneducated due to my poor wording" ok in that sense the whole world is uneducated then according to your stupid logic because people don't speak the same language.   I will settle with "f.ck you American refugees" You'll be refugees in 4-5 months whether you ...

There is no such formula that can compute the battery voltage drop accurately per say.   Because voltage drop does not depend on your load alone, it depends on power source.  If you don't believe me, try this:
Put a 20 ohm on your BIG 12V power supply, measure voltage drop, record ...

I have a cable box with three pins on the back, constant 9VDC, GROUND,
and 3VDC(when switched by remote, normally 0VDC). I want to use the
GROUND and the 3VDC to switch RCA style Video and audio lines, that's
four lines per source (video, audio left, audio right, and ground). I

I hope this isn't inappropriate for here, but I'm looking to make some
white LED lamps (task lights, music stand, etc) since I can't find
anything that suits my needs. I'm wondering if anyone can direct me to a
supplier for goosneck parts or other lamp-arm parts?

Can you define the meaning of the line over 3 dots symbol as used on
many wallwarts? Does it just mean dc, or unsmooothed dc, unregulated,
or what?

I'm generally OK with electronical things, but hardly an expert on
rechargables, from reading the posts here. So, thanks in advance;
here's the question:
Like a lot of folks, i have a pile of those solar yard lights with a

I'm winding a coil for a crystal radio.  The original plan says to wind
the antenna coil on top of the tuning coil, whereas another version says
to wind the antenna coil *adjacent* to the tuning coil, separated by about
1/4 inch.

I'm trying to drive some LEDs with standard batteries (eg. from a
battery holder with 3 AAAs in it). Should be easy ... right?
There's various colors of LED which need from 2.2 to 3.3 volts at
around 25mA and I want to drive maybe half a dozen from the battery
