This 1969 circuit generates a high voltage that reaches 100 V from 16 V. The power is of the order of 280 mW. The number of diodes determines the voltage multiplication.
This small MW transmitter emits its signals at a distance of a few tens of meters, depending on the...
We found this circuit in a documentation from the 50's. The transistors are germanium types. The...
This bistable touch sensor circuit uses a relay and is very sensitive. We found it in a 1990...
