I got some nasty pop ups when I went to that link you just put on.????????
I can see how you could get a hamster running hell for leather in a small router or trimmer. What I want to know is how on earth did they get two and a half horses into my big router and does the RSPCA know about this? :confused: And watt are these mysterious things that everyone reckons is equal to a horsepower and why won't anyone say watt they are? :D

Getting back on track, Peter. Win98 computers have this function in the setup, ie when you turn the computer on, amongst all the crap that scrolls up the screen is "hit DEL to enter setup" (or something like that, it's a while since I had Win98). Go to "Power Management Setup", scroll down to "PWRON after PWR fail" and toggle it to "off". Then your computer won't turn itself on when the power comes on again. I used the feature the other way, ie. to turn the computer on when I switched the power point on at the wall that had everything connected to it, printer, modem, speakers etc.Quote:

Thanks , now I see why you get the big money.Quote:

Drop the voltage and the amps drop too, not increase.
Now Bob, umpire, mate, I want you to go back to whomever it was that said I was wrong and Just explain to him....If you don't mind.
If you feed hampsters on good pancakes they will run like a horse...true.http://www.woodworkforums.ubeaut.com...cons/icon7.gif

The theory involved with electric motors is far more complex than mere Ohms Law.
The performance of electric motors are influenced by
Mechanical loads
Voltage
Current
Resistance
Inductive Reactance
Capacitive Reactance
Magnetic properties of the iron (etc) in the motor
Hysteresis
Phase shifts as a result of the motor design.
Frequency, and possibly other things I can't recall at the monent
Significant errors can occur if you apply simple ohms law to a motor.
Dynamic testing is the only accurate way to assess the relationships of voltage and current, (unless you are a design electrical engineer)
Generally if you halve the voltage applied to the motor the performance deteriorates but the speed doesnt reduce very much. (The same applies if you double the motor voltage, the current doesn't increase very much)

I found the easiest way to sell insurance was to let the client buy, that saved me a great deal of effort.
(Ex. Pearl Assurance man now AMP)
Pete, you are on a hid'n ta nuth'n, stop now. :cool:Quote:

Somethings are NOT what they seem on paper, even if you ARE using a calculator. ;)
There's a differance between electrical & electronical.
Electrical is simple, electronical is complex.
Once you move away from straight DC & purely resistive loads, it becomes electronical.
You can still use simple laws for calculating loads with houshold AC power if you don't start F'n around with the voltage 'cos the stuff was designed to behave fairly normaly at those set voltages. Once you start dicking with the voltage, you are outside the normal design parameters & they don't, READ DO NOT, behave according to simple laws that you can work out in your head or even on your calculator.
Now, let's get back to the more IMPORTANT things in life.... 42?
Test ya pancake mix on THIS!!!! :D
(don't ask me how I found it 'cos you won't believe me.)
WHAT DATE DO YOUR CHILDREN BREAK UP FROM SCHOOL???????
Kids have been known to use other peoples computers!!!!!!!!!!!!!!!!!
Re those nasty pop-ups - if you have windows XP get service pack 2 (the CD is free from Microsoft) - it stops them all.
Caution!! - it can also stop your bank, etc, popups so you may have to enter your bank's, etc, web address(es) in the exceptions box.
Out of the steaming mist from decaying gobbldeygook comes the one man that has kept head clear of all distractions, and pancake recipes, to give help in the original reason for the post.Quote:

"the steaming mist from decaying gobbldeygook"
Now that is a brilliant phrase PeterR, seems a pity to waste it in one big paragraph so I might see if there are other places to use it.
Actually getting a straight answer after only 4 pages is pretty good going!
Give it back,Bob, or I'll tell. Too bloody late, you've already used it in another post - you are a plaga....plagr.....plugg.....a word robber.Quote:
