I have taken a real intrest in building my own circuits for a hobby. I just don't know where to get started. I know next to nothing about this stuff. What I'm looking for is a solid starting point. Should I buy a beginners kit like the what parallax offers or get something else? I am just so overwhelmed with all the informtion. I also need to know about what tools are recomended to start me off. It would be best to keep the cost down at this point. Please show me the light!
