Energy Consumption program 10 Years Ago by Prisms … to start on a personal project to see how much energy I was using when I had my laptop, tablet or…. I was thinking of trying to write my own volt meter application and using a timer to see how much power… Re: Making GUI to talk to an energy meter for calibration purposes 10 Years Ago by Ancient Dragon Windows Forms is c++/CLR, which is a slightly different language than c++. c++/CLR is more like C# and VB.NET and all three are based on the .NET framework. But for quick GUI use Windows Forms. None of those options have anything to do with serial communications. Once you have the basic GUI coded and running you can use the [Serial Port class](… Re: Making GUI to talk to an energy meter for calibration purposes 10 Years Ago by tinstaafl It would probably help to break your problem down into parts. First decide what language you will be using. Since you want a GUI, using a .net language would probably be the easiest. If you have a background in c++ the c++/clr option is viable. You could also easily go with the C# option. Before you actually do any GUI designing and work, … Re: Few questions about energy 13 Years Ago by ithelp Energy is vibration , which creates ripple across the medium it passes through , so is dark energy something opposite to energy which can cancel the vibration , like I throw a stone in a river , a ripple is created , now is dark energy something which can nullify the ripple in no time ? Is energy also a dimension which is not understood by us? Re: Energy Consumption program 10 Years Ago by ddanbe Very good idea I guess. The first language you have to learn is not computer language but the language of electrical measurement. [Perhaps start here](http://en.wikipedia.org/wiki/Electrical_measurements). In using a timer and a voltmeter alone, you never going to be able to measure power consumption.

Re: Few questions about energy 13 Years Ago by vegaseat The Singularity that was at the origin of the Big Bang was unmeasurable small.
