I've been coming across various articles about napping which made me curious to try it. The one thing I couldn't figure out though, was whether it's worth it to get less sleep at night in exchange for taking a nap during the day. Having tried that for a few weeks now, I can tell you that it is. I've been getting up 35 minutes earlier than I used to, so that in the afternoon I can walk home, take a 20 minute nap, and get back to work.
I build Alton Brown's flower pot smoker a while ago, and have used it quite a bit. The first few times trying to control temperature with a meat thermometer and by adjusting the hot plate inside. This sucked. Then I used it with an oven thermostat, but I found it pretty imprecise. I've finally built a simple circuit controlled by an Arduino that should make all this better.
