I am building a digital master clock using a 32.768Mhz quartz crystal.
I am thinking about temperature controlling it using an old LCD temp module. Embeding the crystal. rc network and temp probe in a small block of hardwood with a heating element.
This is the problem what do I use as the heater?
I think it would be best run a few degrees warmer than room temp so would a resister work?
I could embed the control transistor in with the resistor heater as well.
Any advice or thoughts appreciated.
