Suggested by General Electric in a 1965 document, this circuit can accept a greater number of sensors. When anyone opens the SCR it fires powering the load.
The presented circuit can use an equivalent transistor like the BC548. The configuration, which [is...
In the figure we have a simple timer with two voltage comparators of the four of an LM339. The...
This circuit was found in an 1888 publication. However, since it uses common components, it can...
