We found this circuit in an article in Electronics Now magazine from November 1997. The circuit uses two transistors to measure the temperature difference between them when one receives the wind.
The circuit shown in the figure can serve as a basis for frequency meters, clocks. Stopwatches and many other...
This circuit is from an English book from the 1980s. Transistors can be general-purpose types of...
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
