1) This is all hypothetical, and I'm not about to actually do this.
2) I realize that doing this will be ugly, immoral, and is possibly
illegal in some states or religions.
3) I realize that it's cheaper, easier and all around better just to

I've got a tentative plan to try and log power usage in my home, here's
a summary of the plan:
1) Buy two current transformers like these:

I've posted this to a couple of honda forums but I thought I'd try a
couple of electronics forums too.   Thanks for any help.

I'm looking for an engineer/contractor/producer who can tell me more
about voice controlled technologies. For easier communication, a person
or company within The Netherlands who develops these technologies would
be the easiest way.

I should probably know this but I am not sure.
I have a motorcycle that has a 12V output jack. I have a device that I
need to connect to it which is rated for 5V(+). I also have another
device which is a 12V device.

recently ive made a few posts asking some beginner questions.  well,
here is a summary of my project from start to now:
it started out with me seeing this:

Greetings All,
I'm working on a device to pull wire for welding. The mechanical part
is done and now I'm trying to figure out how to do the motor speed
control. I thought that a PWM speed control would be best because the

I'm a digital disginer who is having to some some pesky analog stuff.
I've been desiging some circuits using pen and paper and a little with
spice.  As far as I can tell the designs theoretically work.
I've designed a a constant current source using npn and pnp

If a conductor has zero resistance, then what is the amperage of a
current flowing though it?
Amperage = voltage/resistance
If the resistance is zero, then the amperage is something that math

What am I missing here?  Current flows from negative to positive, yet
the schematic for a diode points from positive to negative...

I bought a pre-programmed PIC12F683,

, and was wondering what the voltage to amperage output expectancy was.
I am running it off of a 5V regualtor. I tried to look through the

I hope this counts as electronics as it's definitely a problem I'm
having with an electronic circuit, but more with getting it put
together on a PCB board (the circuit works fine).  I'm pretty much a
newbie with very little knowledge so I may be using terms wrong & such.

I need to drive 2 capacitive electrodes with out of phase RF (0-100
Vp-p, 10KHz - 1MHz). For this purpose i got myself one of the T&C power
amplifiers (AG1021) with a gain of 53dB upto 1MHz. I planned to use a
BALUN transformer from North hills (75 ohm: 75 ohm, 1KHz - 2MHz) to

Hi, someone can help me to understand this effect?
I have two inverter in cascade:
   inverter       inverter
vin---|>----vout1----|>----vout

Please read the information at the following link:

This means that if you take a capacitor, and charge it up to it's rated
maximum DC Voltage, and either pinch it in a vise, or hit it directly
