After looking over a lot of posts here I have noticed two things. The first to hit me is it appears that there are a bunch of people trying to get us to do their homework for them. Not cool. Second is there seems to be a huge lacking in the basics of analog electronics. I see a lot of folks jumping to PICs and microcontrollers when the same result could have been achieved with a few transistors at a fraction of the cost. Just an observation feel free to comment or flame won't hurt my feeling none.
