testeur quartz 32khz
here also a photography of the circuit. the SMD transistor should be visible. works fine for 4Mhz, but also no startup from transformer based power supply.
**broken link removed**
from computer USB startup easily.
i will test with E-Block battery (5 to 6 volts) later on today. the design is not critical, i am just interested in the subject.
you can share the flickr link freely for the purpose to discuss the circuit, or maybe even link to it for reference purpose. however, i do not give a guarantee.
