it's a bit late bit regarding litz wire: (post failed to send at the time)

http://home.earthlink.net/~jimlux/hv/litz.htm <say's it's insulated
http://www.mwswire.com/litzmain.htm <say's it's insulated
http://en.wikipedia.org/wiki/Litz_wire <say's it's insulated

It's possible the term is applied differently in different places, but if the wire isn't 'individually insulated' then litz wire is just normal multicore and I don't see what's so special about that for rf applications.

I suspect that just maybe this confusion comes from people seeing that it doesn't have a thick plastic coating covering it. (also generally the insulation burns off when contact with solder is made)

Hi 

@ Otto :
Can you just tell me if your proto is physicaly like that ?
For my language , i'm not German but French 
If your are the same i can start the .... construction

All,
I am not sure if an off the shelf Wattmeter is going to be any good as they are designed for use on 50/60 Hz mains line. My personal measure of success is a device that can feed it self and light a lamp no matter how dim/bright.

Dear AM

I am not sure if an off the shelf Wattmeter is going to be any good as they are designed for use on 50/60 Hz mains line.

The original intent was to aid those seeking a low cost method of logging watts drawn and power usage over time. The wattmeter is intended to be placed on the line side of your power supply. Certainly we realize they are designed for 50/60 HZ sine waves. As such they will correctly reflect the power draw of your power supply plus any load. They have built in power factor correction to allow for leading/lagging loads.

We also know that such devices cannot be used on TPU secondary as the frequency and waveform is not standard. That is why the resistive wattmeter using thermocouples was presented. I have used this arrangement extensively and is far better than guessing power by brightness of lamps.

My personal measure of success is a device that can feed it self and light a lamp no matter how dim/bright.

Certainly if you have a self running system with feedback, you don't need such devices and can just count the bulbs. Who has one of these running?
