This circuit is from an April 1991 Radio Electronics magazine. The circuit uses power MOSFETs and an integrated circuit from that time.
This circuit was obtained from ancient documentation using transistors of the time. The circuit...
I found this circuit in an old Argentine publication from 1973. The components are no longer...
This ammeter measures currents in 5 ranges from 50 uA to 0.5 A using a 40 uA instrument, which can be...
