In this tutorial we will show how to build WiFi internet connected switch connected to EasyIoT Cloud. We will use ESP8266, solid state relay and Arduino IDE. Switch can be controlled by WEB application, native Android application or button. Improved version of this switch can be found here: https://www.instructables.com/id/ESP8266-5-Internet-Connected-Switch-Improved/ This internet switch is “plug and
When designing circuits, many hobbyists take capacitors for granted – but each type (ceramic multi-layer, aluminum electrolytic, tantalum, mica…) has its own unique properties. Nowadays, ceramic capacitors are the most commonly used capacitors in the industry, but many can lose up to 80% of their rated capacitance near their voltage ratings. Enter the OpenCVMeter! This
The ARC was designed to bridge the gap between high-end sound quality and the world of digital music. This ultra-compact system provides high-resolution USB audio and high quality aptX Bluetooth audio for an astonishingly detailed sound. Fully integrated with the latest in class-D amplifier technology, the ARC is a complete high-end digital audio system. For
Kids just aren’t huge fans of brushing their teeth. Not only are they not huge fans, they also are pretty bad at it. Teaching a young kid to brush their teeth is really hard. I created a little contraption that not only times them to make sure they brush for an entire two minutes, but
It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them.
In this project, we will be making a weather station that measures air pressure, temperature, rain drop, soil humidity and air humidity using Arduino which save the data for data acquisition! It’s a fairly easy project and can be used either on its own or part of something bigger, check it out >> Integrated Weather
Automation is defined as using various control systems to operate equipment such that there is minimal human intervention. Closed control loops (feedback systems) regulate how other systems or devices behave by taking into consideration their output and making corrections based on feedback. An example of this feedback system is Progressive Automation Linear Actuators. In this

Voltage references are a humble piece of hardware, their sole function is to provide a stable, known voltage. This constant, known value of voltage can then be used as a reference for ADCs and DACs as well as provide a precision current source. I recently got hold of an Analog Devices AD587KN high precision 10.000V
This tiny Unipolar stepper motor driver has been designed around SLA7078MPR IC from Sanken, It is unipolar stepper Motor driver can handle current up to 3 Amps, micro-stepping up to 1/16 steps. On-board Jumpers to set the Micro-stepping, Preset (Potentiometer) to set the current. The SLA7070MPR series motor driver ICs features unipolar drivers. The clock-in
