Where do I obtain the parts for DIY projects?
The cheapest thermostats are those used by the reptile keepers. They are complete units ready to run, no assembly is required and are priced between $60 – $80 (AUD) . I bought one from eBay for $60, it has a dial to set your temperature anywhere up to 40 degrees, which is basically all you need unless you are intending to make hard boiled egg with it. A probe attached to a long cable is included to allow you to pop it into your brooder or incubator to measure the internal temperature. On the actual box, is a power point where you can plug a heating device on (eg light bulb, infra red lamp , heating mat or heating cable) and the unit is powered from a normal 240V powerpoint. To find these items on ebay or google use key words THERMOSTAT or THERMASTAT REPTILE also try REPTILE HEAT MAT or HEAT CABLE.
