Component Heaters - cellularmitosis/Electronics GitHub Wiki

All electronic components have a temperature coefficient, which means that controlling the temperature of components can yield better consistency from your circuit.

Rather than regulate the temperature in both directions, a simpler solution is to choose a set-point which you know will always be above ambient temperature, so that you only need create a heater to achieve temperature regulation.

A very common use-case here is that of creating a crystal heater to achieve better stability from cheap crystal oscillators.

Here are some heater circuits designed to regulate the temperature of components (or entire circuits):
