Hardware Design Help

I will try to add slowly some basic circuits and characteristics of some components and what way we use them. This will take a while as i need to put enormous amount of time for that.
Need feed back on my website. As i want to add lots of stuff to that again.

Lots of times i had even problems in guiding layout engineer, so will add one section on information about layout which designers should know.
