A few years back, Boardcon introduced EM3399 single board computer powered by a Rockchip RK3399 processor through the company’s PICO3399 SO-DIMM system-on-module. They’ve now designed another RK3399 based SBC , the Idea3399 – comprised of a baseboard and module, but instead of...

Axiomtek - a world-renowned leader relentlessly devoted in the research, development and manufacture of series of innovative and reliable industrial computer products of high efficiency – is proud to unveil eBOX100-51R-FL, a fanless ultra-compact embedded system with weight 600 grams...

This article describes a set of minimal I2C routines for the new 0-series and 1-series ATtiny and ATmega microcontrollers. They allow any of these processors to act as an I2C Master and connect to I2C peripherals. As an example of their use I've designed a digital clock circuit based on...

One of the most important actions in the development of any electronics device is soldering, irrespective of the method adopted, having the right tools to do it the right way is a major determinant of the speed and quality of the soldering process. Several soldering tools exist in the...

The release of mini-laptops with display size in the region of 9" has seen a surge in recent times with several companies like CHUWIX, One Mix, and a few others releasing quite a number of these PCs. To join these growing number of PCs, the Mag1 is joining the fray with the MAG1 “Magic...

The MPLAB® Snap In-Circuit Debugger/Programmer allows affordable, fast and easy debugging and programming of most PIC®, dsPIC®, AVR and SAM flash MCUs, using the powerful graphical user interface of MPLAB X Integrated Development Environment (IDE) version 5.05 or later. The MPLAB...

A volume unit (VU) meter or standard volume indicator (SVI) as it's sometimes called, is a device which displays the audio signal level of an audio signal. It is essentially a basic voltmeter (fitted with transducers to convert sound to voltage) that takes a simple average of the...

This motor driver circuit can drive a brushed DC motor with up to 250W of continuous load. The project can be controlled with the general logic IO-Ports of any microcontroller. Either an Arduino Uno or other microcontroller can be used as the control board. The project uses two IFX007T...
