  I'm shocked! I was watching TV and on the I-TECH show (what's new in Hi-Tech) they presented a new device, an electronic meter, recently developed by some company.. An ease to use device, compact , and more precise than the old tool! &nbsp; Wondering what does it have to do with me? Why am i shocked? Well.. I thought of the idea some time ago.. I was wondering back then what device could a person invent and gain serious amount of money out of it? And i got the same idea.. What did i do with it? Nothing! Asking why? &nbsp; Well.. I would have jumped on the idea right way..
But.. There is a BIG BUT here, meaning, what if the is not 100% straight vertical? This would cause a calculation error. What if a person wants to calculate a flat surface, a 2X2 table for instance? &nbsp; Anyway, I think that if i can come up with such ideas i can, eventually, fix it's defects.
