Hate to revive a dead thread but think it needs to be said there are many of us who homebrew because we love building things and solving problems. Some of us are comfortable working with electricity and build things in our everday lives. If this isn't you, then please don't do this as a first project... spend $20 and get a reptile heater. For me, spending an evening tinkering with discarded equipment in my basement was fun. I ended up with a 35 watt bulb I found and anchored it in a ceramic fixture and put it all in a small electrical box. All this stuff was collecting dust in my basement. Total cost: $0.. If I didn't have this stuff I would totally get a reptile heater.
