Often, simple robotics projects are powered from a small power bank consists of common dry cells (1.5Vx4=6V) or Lithium-Polymer cells (2S LiPo=7.2V). Ofcourse, the 5V required for the microcontroller ...

A lithium-ion battery tester seems like a simple project, at least electrically. But when you start thinking about the physical problem of dealing with a huge range of battery sizes, things get a ...

The bulky batteries that power mobile devices could one day be extinct. Oki Printed Circuits has showcased technology that embeds a 170?m-thick thin-film all-solid-state lithium-ion (Li-ion) ...

Explains electric current, highlighting that it originates from a battery and requires a complete circuit to flow. It compares electric current to water flowing through pipes, using meters to ...

If something runs on batteries, you’ll find a battery meter somewhere on it. Your smartphone, your vape; even batteries themselves can tell you how close they are to dying. So why am I excited about ...

Isn’t it always the way? There’s a circuit right out of the textbooks, or even a chip designed to do exactly what you want — almost exactly. It’s 80% perfect for your application, and rather than ...
