This circuit is about a buck regulator which can produce an output of 5V for a input voltage ranging from 7V to 40V. LM2576 is a monolithic IC and it acts as the heart of this circuit. This IC has a potential of delivering an output current up to 3A and requires less number of...

For the exponentially growing data traffic worldwide, the data connections within and between microchips are increasingly becoming a bottleneck. Optical connections are an obvious successor, but that requires an adequate nano-sized light source – and this has now been found. Researchers...

Bob @ electrobob.com tipped us with his latest article about RFM69 module. As I was mentioning in my 1000.1000 Hardware selection, I have opted for the cool RFM69HW radio module. Weirdly enough, in quite a few sources (big distributor and ebay) the higher power HW module is cheaper....

Craig writes: I’ve gotten a lot of questions on the blog about the new version of the MHS5200A function generators available on eBay. Viewer Tolga was kind enough to send one in to me to review and tear down. Although some improvements have been made over the older models, there...

via elektormagazine.com: New in the Electronics Design Library is Volume 2 of FOCUS ON: Bob Pease on Analog. With very few exceptions Bob Pease is remembered fondly all over the globe for his analog design expertise as well as his sense of humor. Our esteemed competitors Electronics...

In this video educ8s.tv is going to show us how to use interrupts with Arduino, an advanced but extremely useful feature of the Arduino. But what is an interrupt? Most microprocessors have interrupts. Interrupts let you respond to external events while doing something else. Suppose...

Researchers at Cardiff University use 3D printing to create small devices that move small volumes of fluid and are used in various areas of research. 3D printing makes it possible to share the devices with other researchers, making the study of microfluidics more accessible to a wider...
