I built this watt hour meter to track power usage and production for my solar powered ham radio shack.
It uses a hall effect sensor to track current, and a voltage divider to monitor voltage. I calculate watt, watt hours, and amp hours.
Wow Thats so cool Steve,
They can knock out our satellites but they wont silence you will they. I think Ham radio is over looked and I don't need to tell you how there hoging our air waves with stuff that will not work in dyer need. I'm not a Ham but I have lessen to some while at large lurking in at some forbidden freq's. I did CB once. 25mile reach is a joke to you. I picked the wrong handle. (Daisy) Dasiy Duke they called me ... Crap, can't win ...
Glad you liked it. I'm working on a ps/2 keyboard to morse "radioteletype" for non-code folks to be able to participate. Incoming morse will display as text.
