Exactly how handy are you, Andy? Heh! I made this temperature controlled outlet that I used to use for my smoker. I currently use it to make stock (2016 Thanksgiving shown), for sous vide, and to turn the lights on to keep my lime tree warm on the rare occasion that the temperature drops into the low-30s.handyandy said:huh, good to know I have couple old block heaters for diesel engines that just plug in and get red hot might use those instead rigged on a timer to cycle them.
It's one of these: https://www.amazon.com/gp/product/B005T5EGC4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
And one of these: https://www.amazon.com/Inkbird-All-Purpose-Temperature-Controller-Fahrenheit/dp/B00OXPE8U6/ref=sr_1_2?rps=1&ie=UTF8&qid=1511199703&sr=8-2&keywords=digital+temperature+controller&refinements=p_85%3A2470955011 (mine is a different brand, but they're all the same)
And then all you need is a standard outlet socket (scavenged mine from a battery backup), some flexible house wiring and wire nuts (Home Depot), and an IEC jack and cord (scavenged from an old computer power supply). The whole thing is wired up with wire nuts, so no soldering. Replacement sensors are $4.50 for 5 on Ebay [link].
It's a handy little device to have. Set your temperature, and stick the probe somewhere. When the probe goes below the set temperature, power is applied to the outlet. It made it very easy to cycle the hotplate to keep the right temperature. It is also very easy to read from a distance, and in the dark.
