James Lewis from Kemet has made a presentation to address some of misconceptions about capacitors like how you should de-rate capacitors. James said that de-rating depends on the chemistry and configuration of a particularly capacitor.  So he started by asking a question: Should...

Ahmad Al-Shalabi and Bassma Karbouj show us how to control a DC fan using easy to find components. The fan works when temperature reach into pre-specified threshold. The purpose of this project is creating a cooling system by controlling in a DC fan in a simple way without using...

Vasily Ivanenko build some discrete chip oscillators with 74HC series logic gates and tests them on his oscilloscope. He writes: In numerous RF synthesizer chips lies an inverter with input and output pins for making a reference crystal oscillator clock. I built some discrete chip...

Bosch Sensortec announced a new 9-axis motion sensor, the BMX160, on June 21, 2016. BMX160 targets smartphones, smartwatches and other wearables applications. It has a low power consumption (580 μA), which is proper for long working time on battery for this type of applications, also...

Espressif announced ESP8285 a Wi-Fi chip for wearable devices on May,2016. Some described this chip as the killer of ESP8266, that is because ESP8285 includes an embedded 1 MByte flash memory. This means smaller area in PCB is needed to include your Wifi chip while the old ESP8266 needed...

If you’re one of EAGLE CAD fans, and you were wondering how some boards like Arduino boards have what's called a negative silkscreen, hollow rectangles or shapes by text or logo, then you will learn how to do it with Ishaan’s video tutorial. Ishaan used a ULP called...

This tutorial is going to teach you the basics on using OLED 0.96inch LCD128x64 with Arduino. OLED 0.96 inch is a monochrome graphic display module with a built-in 0.96 inch, 128X64 high-resolution display. OLED 0.96inch is able to work despite the absence of backlight. In a dark...

educ8s.tv uploaded the last video of this season and it's a different one! The first one, is this: Practical Electronics for Inventors. Since I studied computer science and not electronics engineering at University, I needed to find a good book to study electronics myself. After a...
