Many of us are familiar with photosensitive switches made with a single transistor that is controlled by a photoresistor placed between the base and the recharger, depending on what is desired: normal ...

This analog switch circuit is designed to switch on or off and analog line. it consists of two analog switches in IC form that are controlled by two pushbutton switches. In standby mode the voltage at ...

Deadman circuit development We developed the Deadman kill switch to serve as a passively activated biocontainment system for engineered microbes. Similar to pioneering biocontainment systems in E ...

Horrible Science fact It's all well and good having a perfect, simple circuit but it it includes a switch, it will only work if the switch is in the on position meaning the circuit is closed. You ...
