This very low power circuit is based on the ICL7860. We found it in an Electronics Now from April 1995. The output current is very low.
With the coded activation of the relays, it is possible to control which of the 16 outputs...
The integrated circuit used in this application is not very common. Transistors and resistors...
This simple circuit makes use of neon lamps to indicate the voltage of a power grid. The lamps are...
