Adam I've got some micro control experience dating back to the early 80's, having to do with fine control of heating and air conditioning equipment. At that time it was still, replace the individual component, instead of replace the entire board. Replace the entire board came about 3 years later. So, I can read a schematic, I can solder and I remember some electrical theory and fundamentals and we have this wonderful internet that's like having the library of congress in your living room, so I figure I'll start remembering some of it, and I can study up on what I forgot. So, I'd like to design something myself, or I can go off a kit for the first one just to remind me what's going on. I want to start doing these clocks, etc. with my sons, so they can learn some basic electrical fundamentals, and learn how to solder, and have some neat father/son time together. Also, I wanted to try to make an over thermometer because analog oven thermostats have a 15-20 degree temp. swing in them. So I thought that would be an interesting project. Some people like to have a little bit more fine control over their ovens. And then I stumbled upon this board, and it seems like there are a lot of experts here.
Well, gotta run, talk to y'all later.
