This is a simple clap switch circuit with high sensitivity. The only unusual component is the single coil latching relay. While there are numerous means of generating the latching function, the ...

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 can learn more about ...

We usually tend to switch things to ground as seen by outputs such as an Open Collector output ... Hopefully this is an example of a simple circuit which you may find useful at some point ...

The triboelectric effect can be used in a simple switch (Fig. 1). A metal tine wrapped with Teflon tape is sandwiched between pieces of copper-clad epoxy circuit board stock and covered with ...
