Thermostat for heated enclosure
Hi, I was thinking of making a thermostat for the heated 3D printer enclosure that I am building. In the past I have had issues with ABS 3D models curling up on the edges, due, I think to unequal temperature distribution over the print bed.
I want to keep the enclosure at a constant temperature, using a normal incandescent light globe. In the past my (now deceased) father used to keep the honey that he produced, warm and flowing easily, using a similar method, but he used the thermostat from an old hot water service to control the temperature by switching the globe on and off as required to maintain a constant temperature.
Times have moved on, and I was thinking that I would use a solid state relay to do the switching of the 240v lamp and a thermistor to sense the temperature of the enclosure.
I was wondering if there is a relatively simple circuit to do this? I can of course use google to search, but I have been a little overwhelmed by the number of results and possibilities with which I am presented.
Thanks in advance for your help

Your fathers design is a good method, another used by home wine and beer makers is a lamp controlled by a tropical fish tank thermostat so don't rule out the 'old' technology!
RS also sell a low cost thermostat both electronic and contact
If you want to make one, obviously you need to consider mains voltage and safety!
Some good simple analogue examples are here:
Then there are all the digital possibilities using a microcontroller reading a sensor and driving a relay....
Hope the above gets you started
