In this simple but effective project, you will learn how to make a simple circuit using a 9-volt battery, LED, and pencil drawing. This project is a fun way to explore and learn about the science of ...

Here is a VLF receiver tuned to 300 kHz designed to detect the crackle of approaching lightning. A bright lamp flashes in sychrony with the lightning bolts indicating the proximity and intensity of ...

Cooper Lighting has reduced the power consumption of its pioneering RXD1 LED downlight to just 25W, resulting in an energy saving of 56% when compared with equivalent 2 x 26W CFL downlights, which are ...

The following circuit uses a low-power CMOS comparator and an LED to indicate low-battery voltage without causing excessive current drain. To view the application note, click on the URL below. Circuit ...

Here at STEAM Powered Family we LOVE our owls. In fact we are kind of obsessed. Another one of our loves is building simple circuits. With this project we have brought both of those loves together to ...
