In this video educ8s.tv is going to compare the computational speed of the WeMOS D1 ESP8266 based Arduino compatible board with the computational speed of the most popular Arduino boards and the Teensy 3.2. A few weeks ago, in a similar video we compared the performance of the Teensy...

This is an ATtiny Dev Board. Designed for the ATtiny line of microcontollers from atmel. Its made to be small, simple to build and easy to use. ATtiny Dev Board / Tinyduino -...

pinko @ exrockets.com has published a mini barometric altimeter based on PIC18F2553. He writes: I found on Ebay very nice, small 12v 23A battery holders for PCB mounting style and decided to fit the SMALL DIGITAL BAROMETRIC ALTIMETER just on the back of the holder. So basically...

circuitbasics.com has published a series of tutorials on the most popular communication protocols, like UART, I2C, SPI etc. Check them on the links below. Basics of UART Communication Basics of the I2C Communication Protocol Basics of the SPI Communication...

17 of the most common hard switched power supply topologies and the Phase Shifted Full Bridge with the most important waveforms and equations are now available for you in an easy download-and-print option. Power Topologies Quick Reference Guide from TI -...

Bob @ electrobob.com tipped us with his latest project. It's about a power supply tester. What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the...

Shahriar @ The Signal Path did a teardown and repair of Tektronix RSA real-time spectrum analyzer. In this episode Shahriar attempts a difficult repair of a Tektronix RSA real-time spectrum analyzer. This well-equipped instrument reports several error messages during startup POST...

The LTC2944 measures battery charge state, battery voltage, battery current and its own temperature in portable product applications. The wide input voltage range allows use with multicell batteries up to 60V. A precision coulomb counter integrates current through a sense resistor...
