NTC Measurements (Pt. 2)

In the previous NTC Measurements article, was shown the basic approaches and few variations of them in order to use an NTC, by following the suggestions provided in the datasheet and taking the correct assumptions in all the temperature signal processing. These suggestions are usually not  provided,  because with a  bit of math a lot … Leggi tutto NTC Measurements (Pt. 2)

Smoked crystals (Oscillator)

Once upon a time, during a lecture about electronics, more specifically on crystal quartz oscillators, a professor said that you can break a crystal oscillator by dropping it, because the quartz inside can be broken due to the fall, even if it seems solid like a common 1/4W resistor. Let me start with a briefing … Leggi tutto Smoked crystals (Oscillator)
