Default How to make, where to buy, order 5 kHz, 10 kHz, 15 kHz crystal/ ceramic resonators


At 15 kHz, an AT quartz resonator would need to be (in size) about 200
times that,
2 cm thick (and broader than it is thick, so it'd be a Frisbee-sized
disk). They don't
make those, as far as I know. Normal mortals couldn't afford one.


This guy came close , quartz ring, not a frisbee, but close :
