I have a new Topower TOP-500P5 PSU that has a separate line with 2 SATA
power connectors on it.
My hard drive is new but not SATA.
Is there an adapter available so I can run my 160GB IDE drive

I have read prior thread (1996) in this forum, explaining theoretical
problems with the bond between aluminum wire and, say, terminals provided on
duplex receptacles.  Aluminum has interesting, accelerative failure mode
when too much current is applied.

I'm looking for diagrams or schematics of switched power supplies with
(preferably ) 50V AC input to 24V DC output. Does anyone know where to find
these?
Hope someone can help.

How common are Aluminium bobbins for 50/60 Hz
chokes and inductors?  This is the first one I have seen.
I was at a ham radio field day recently and picked
up a heavy duty coil which I thought might make

I have several Failed In Use
"Advance ®" standard REL-4P32-2C  Ballasts~[electronic] ...
I had worked with some   "Sassy®" ballasts that have a fuse., these
don't ., but are failing and accumulating.

I'm trying to figure something out and so far no one has come up with an
answer.
If I have a voltage divider network (Just 2 resistors) and I bypass the
bottom one with a cap with an AC source in. How do I figure out the

This is an electrical question pertaining to derating more than three
conductors in a single run of conduit.
I am feeding a 54 amp, 220 amp tankless hot water heater, and a 5000
watt, 220v A/C with electric heat from the main panel through 1 1/4"

All:
The wiring diagram on the motor (for a Graymills centrifugal pump) is
EXACTLY the same for both voltages!!  This can't be right!
Here is the schema for the low voltage wiring:

Having trouble with house telephone - the handset batteries constantly run
down...suspect the small powerpack transformer attached to the phone base
that plugs into the mains that's supposed to keep battery levels topped up.
Its a little transformer to convert 240v AC to 9.5v ...

I've been given a Megger (500V Hand Generator), it's not
actually a Wheatstone bridge, but it does do the Varley
Bridge measurement.
Resistance measurement from MegOhms to MilliOhms!

Hi all I am helping a friend promote a web site. You see a childhood
friend of hers lost her husband at the World Trade Center on Sept. 11,
2001. She has run into some hard times and my freind wants to help her.
So she came up with the idea to market Just say NO to Bin Ladin

Jeeze folks... this little lawn  mowing didn't take long.
I should stop by more often.

Hi eveyone,
I am soon in the market for a new NEC 2005 book.  I heard second
printing has been planed a while back, but find many sites selling
books not stating which printing it is.  

I am doing a college course and am looking for a process simulation program
where I can set up a simulated a process on my pc and dabble with PID
settings to tune a controller in response to process upsets or setpoint
changes.
