Do you want to know how to use a 555 timer? Laura brings you more Back to School tips and tricks on using this integrated circuit. Basic Electronics - How to use a 555 Timer -...

Mark Maddox @ edn.com has a design idea on cold-junction compensation using AD7708. The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a...

LT8303 is a monolithic flyback regulator in a TSOT-23 package that simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator, LT1431 or third winding for regulation....

The single supply microphone pre-amplifier amplifies the output signal of an electret capsule microphone to audio line levels. An op amp is used as a trans-impedance amplifier to convert the output current from the microphone in to a signal level voltage. The circuit works with 9V so...

A new type of batteries called “Printable Solid-State (PRISS) Lithium-Ion Batteries” was designed by a group of researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea). The new battery is created from consecutive layers of printed composite...

This is a general purpose relay board accepting 8 inputs to drive 8 relays providing control requirement in your project. This board can also be used as an add-on card for the various Development board that we provide and various microcontroller boards. Features Robust Design...

by S Kaliyugavaradan, Anna University, Madras Institute of Technology, Chennai, India; Edited by Brad Thompson and Fran Granville -November 10, 2005 Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low...

The pi-top converts your Raspberry Pi into a complete RPi notebook. by René Bohne @ elektormagazine.com It comes as a nice kit that is very easy to assemble thanks to a great construction manual. We created a video of the assembly. If you have any questions, feel free to leave...
