fan starts to rotate at +40 C on the heatsink
The fan is reverse mounted so that it will blow cold air into the heatsinks and transformer. The NTC is glued with epoxy to the heatsink with the powerdiode, The fan controller is changed so ...
Car Water Temperature by CA3161 CA3162
The circuit measures the car water temperature. CA3161 , CA3162 is a counter and 7segment driver to display amount of temperature on 7segments. The temperature sensor is a diode, 1N4148. This is s ...
Thermal Fan Controller by IC 741 and Diode
The controller uses one or more ordinary silicon diodes as a sensor, and uses a cheap opamp as the amplifier. I designed this circuit to use 12V computer fans, as these are now very easy to ge ...
