This circuit for currents from 500 mA to 1.5 A was found on a Ham Radio from the 90s. R4 determines the current in the load under test. Transistors must be equipped with radiators.
This constant current source is from the LM11's own factory manual used in the application. The circuit is...
This circuit, from a 1988 documentation, consists of an automatic temperature control using an NTC...
With this name we already published an interesting game. For readers who do not know, this game...
