Simple to build isolation transformer that consumes less power than it gives out

TheCell:

Thank you for correcting me, you can multiply Vrms x Irms to get a proper power measurement.

If I can offer a suggestion it would be to use power resistors instead of light bulbs because light bulb resistance varies with intensity/temperature.  Then connect a True-RMS voltmeter across the power resistor to calculate the output power.  The transformers may saturate which would distort the sine wave and you can see that Wattsup's sine wave is not a pure sinusoid so using a True-RMS meter would be advisable.

Thanks for sharing regarding your fascinating replication, Wattsup!  More power to you!

You might use a watt-meter (e.g. Kill-A-Watt) on the input power also, as a check. 
Also, why not run straight from the mains?

Have you tried rectifying BOTH outputs?

Thanks for admitting this, MileHigh --

MH, How can you expect people to take your suggestions seriously when it is that these people have to correct you on the fact that P=IxV?

I know that you admitted the mistake. But guess what. Now these people have to overlook all that you post. The reason is, when it comes to something as simple as you saying that P cant be derived from IxV, then what are we to think when you post something more complex than P=IxV?  Now we have to question everything

I know you have knowledge and some skills. And you have repeatedly blamed lack there of on the fact that it has been 30 odd years since tech school. Just the other day you said it in the Tar Baby thread, again.  Call me a liar on that one. ;]  If you do, I will provide a list of posts that you state just that. If you like. ;]


Yet with quite a few similar stumbles, a memorable one is the led that biases on at 1v, you still assert yourself as some sort of elder of knowledge, telling people they are fools and such, just because they are very interested in a subject.

You need to reread(and rethink) your posts before hitting that button. Because if you are going to stand up and jump in as the Wizard of OZ, if you keep stumbling like that, these people will find you in that little box, hiding, pulling levers and knobs, trying to make people believe somethings that are really not.

These people are going to experiment and continue to learn about these subjects, whether you post you interruptive oppositions or not.   If we go to look at your posts here at OU, and even just skip the Tarbaby thread posts, what would we see? Its real easy. Just click on Milehigh and click show posts.  Its all there.

I see a lot of negativity in just about every thread you post. I have not yet seen a post from you that shows you trying to help someone try to "advance" on a project.
Why? Because you always oppose any ideas or claims of OU. You are never ever positive on these subjects. Most of us know where you are coming from.

Magluvin.

That's just a bullshit posting by you were you are strutting around puffing your chest out and stroking your ego because you saw me make a mistake.  If I corrected every single error you made and made a big stink about it and gave a speech you would not like it one bit.  The LED example is more bullshit because if someone else made the same mistake you would have politely corrected them and them left it at that.  With me you ran around like a crazy person screaming your lungs off.

Don't start this nonsense again where you are going to "go after me."  What you do know is that I know my stuff and I am not perfect.  Big farking deal.

In my previous posting I was trying to help Wattsup and I made a mistake.  Do NOT make the conscious decision that you are are going to try to make my life miserable every time I make a mistake.

Mags don't you remember we gave that job to Wilby??
{a side note ,I believe wilby was awarded two Gold stars for his efforts in the "Rossi" thread]
Thx
