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 ...

With this one simple circuit, you can hack into sleep and help overcome insomnia. How to hack your way to a better night’s sleep. How I design projects from start to finish. Some further ...

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 ...

Use the same concept above. The initial investment is the cost of the new gear and the ROI is based on circuit cost savings. ROI is a great, simple tool to show managers and sell your project. It ...

Amoebas are smarter than they look, and a team of US physicists think they know why. The group has built a simple electronic circuit that is capable of the same “intelligent” behaviour as Physarum, 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 ...
