It’s late at night. The solder smoke keeps getting in your tired eyes, but your project is nearly done. The main circuit is powered by your 13.8 V bench supply, but part of the circuit needs 9 V. You ...

This simple and cost-effective ding dong electronic doorbell circuit is based on IC 8021-2. The IC has an in-built circuitry to produce ding dong sound each time its pin 3 is pulled low. The sound is ...

The design of the project consists of a few simple electronic components to create a metronome device that can be used as an invaluable practice tool for musicians. The term metronome refers to ay ...

Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constant current load, ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

Electronics-loving orthodontic clinician Dr. Mark Brickley has developed a collection of electronic circuit-building experiments, tested them on unsuspecting colleagues, and then squeezed them into a ...

AMOEBAS are smarter than they look: their bodies can store rudimentary memories. Now a team of physicists has built a simple electronic circuit that behaves in a similar way. When amoebas are ...

Every rose has its thorn – but roses grown in a Swedish lab have transistors and electrodes too. Researchers at Linköping University have created bionic roses by incorporating plant-compatible ...
