Herbert,this is not the place to discuss this but how much do you know about my knowledge ? If you have some opinion about it from my questions and directions,you are watching too much hollywood. I have an EE major and MBA,If everything goes ok I will be finishing my Ph.D till the end of 2007.Although you are right,my field is not power systems. There are lots of reasons why I seem to be stucked on an inverter. 1)As I said,all of the power inverters (ok,relax,lets just say most of em) has power-cut feature.This is a good feature to have.Why should I bother to build an apart module while I am able to handle most of things in one design. 2)I may be running other stuff (like a printer,digital satellite reciever[for special purpose] or a wireless booster) 3)It's open for development.You can get almost whatever you want from city electricity formatted electric without bothering yourself to design special purposed modules which are going to work only at that system. > Why do people fixate like this on THE ONE SOLUTION, when they have competent > people advising them that their solution is unworkable? This is what we call thinking wide open.Don't think of this approach as I don't know what I want - I do.The one solution you are talking about is going to be roots of another solution for the future.If I need a refrigrator at my car,what is going to happen ? Another bright solution will be coming up from competent people ? In time,My car is going to be full of competent peoples advises because I will be putting a special module for each thing I want to use.I appreciate your will to help - I really do but what kind of an investment philosophy is this ? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
