Hi,
I'm building an analog/digital clock based on a quartz crystal pierce oscillator. A goal of this project is to learn how each part comes together and eventually produce a high quality prototype (lack of better term) mounted inside a wooden enclosure. I am happy with the circuit design aside from failing to include temperature control. I don't want to get too crazy with controlling temperature because feedback is currently beyond my understanding which I can return to later.
Alternatively I am considering methods and materials to soften the temperature gradient experienced by the enclosure when exposed to sudden changes such as a door being left open for 10 seconds in the winter, here in Canada the breeze is a nice -40c at times! I haven't done enough testing to know how rapidly temperature changes a quartz circuit.
Temperature and fire suppression are aspects I'm investigating as long term fidelity of this project is important for my understanding. Any information on the topic is appreciated.
Regards,
