I'll start with my ghetto fermentation chamber. My house is pretty cold in the winter so I needed something to help maintain a slightly warmer temp for my fermentation vessel during these cold months. Rather than investing in a fancy chamber, or cranking up the heat in my fermentation space, I found an old piece of foam in my basement which I use as an insulator. This stuff works like a champ for temp maintenance...I actually use another piece of this on my MLT keggle. When I need a bump, I wrap a heat pad (like you'd use for sore muscles) inside the foam insulator and moderate the temp control with the switch (mine has three levels). I don't want a constant application of heat, and may want an extra bump in the middle of the night when my fermentation room temp drops, so I can actually run this through a light timer to give it a bump every couple hours. I've been running the first stage of a lager in a room that's around 40 degrees, and this set up has helped me keep a constant 50 during primary. Here's a photo:
