Power Meter
 
Has anyone looked at the power meter over at http://www.snippets.org/filters/wattmeter.htm ?

It looks interesting, and may be somewhat useful for testing stuff.

Thanks,
Paul

well looks simple enough to implement

for $5 you can get the chip from digikey (canadian that is!) and another $5 for led's ..
so $10 all in all to make it .. maybe i'll try it too! ;)

although i would love to find out if it works or not as well

Testing ... what stuff? Seems good for RMS wattage but if not true RMS? I dont think it will be good for testing you wall outlet (how much your computer consumes) except for things with cos fi of 1 (that is resistive)
Please correct me if Im wrong!
But Ive used this IC for some of my projects and its OK.

Jens,

As I have sent it to another member already it`s ready for "emailing".
The scans are rather big (even already downscaled in resolution) - can You receive 4MB without problems (but could send it in parts also)?
