I'm thinking of using a $5 candle warmer as the heat source for a small incubator. Less fragile than a light bulb and less likely to burn out. anybody ever try it? Mrs Delmar has a couple of them laying around. If I get the hatch done before the heating season ends I might not even need a thermostat. Just hook it to a dimmer switch to regulate the temp and keep it in a 70 degree room.
