Interesting idea with the ICSP strip. I have a Willem programmer that I have been planning on using, and can't really afford to branch out for the moment, but it's something to think about nonetheless. Is it a good idea to have just in case I want to do some reprogramming? Or better yet, is it something I should be doing and just nix the Willem programmer? I also like the wider traces. Seems like it'll make for a longer life for the project once it's built. The charlieplexing idea is a cool one, mostly because I love anything that concerns maximizing efficiency, and also because I have never built one. It may be superfluous given that I think I just want to go with variable times for the fan to be on, and not variable speeds. I will work it into a future project if I don't go with it on this one though, just too cool to not use. I am planning on making a remote starter for my car, so I am thinking I could put it on the fob that goes with that. I am also concerned about keeping costs low, so the LED's may be an extraneous cost for this project. I just had in mind a power switch, and then a switch or knob to control how long the fan stays on. I have a few ideas rolling around in my head, so the charlieplexing will get used sooner than later. Still no thoughts on the code? Is it right? Is it complete?
