During the academic year of 2016-2017 at McMaster University, in conjunction with Dr. DeBruin, Christina Riczu, Thomas Phan and Emilie Corcoran, we developed a compact, battery powered, 12-lead electro-cardiogram. The project won 1st place in the biomedical category at the ECE Capstone Poster Day. The final report we handed in for the course is attached […]

Why did I build a power bank? Why would anyone even try to build a power bank – i.e. an external battery for charging mobile devices – these days? These things are commodity, it’s impossible to compete. Right? Well, that is until you find out that the type of power bank for your application, namely
First unveiled over the weekend at World Maker Faire New York, Arduino has introduced a pair of new IoT boards with embedded LoRa and GSM capabilities. The Arduino MKR WAN 1300 and MKR GSM 1400 are designed to offer a practical and cost-effective solution for developers, makers and enterprises, enabling them to quickly add connectivity to their projects and ease the

The terahertz (THz) region, which is based on 1THz frequency, separates electronics from photonics and has been difficult to access for ages. Semiconductor electronics cannot handle frequencies equal to or greater than 100GHz due to various transport-time related limitations. In other hand, photonics devices fail to work below 10THz as photon’s energy significantly drops to thermal energy. Terahertz
As Internet of Things (IoT) devices are optimized for lower power consumption and affordability, most of them have poor computing resources. As consequence, these devices are more vulnerable to hacking attacks. The good news is there are several options for using cryptography to make it difficult for hackers to gain access to IoT devices of your smart

Over the last several months, [Aaron Christophel] has been working on creating a custom firmware for cheap fitness trackers. His current target is the “D6 Tracker” from a company called MPOW, which can be had for as little as $7 USD. The ultimate goal is to make it so anyone will be able to write

Hi! In this build we’ll make a good looking light that dances to all sounds and music, using simple components and some basic Arduino programming. It makes an awesome effect while standing on the desk when gaming, playing music, and anything else that makes sound really. Let’s get going! (Click here to download schematic) STEP 1:
Synchronous four-switch buck-boost controller suits transport and medical use A 150V high efficiency four-switch synchronous buck-boost DC/DC controller, the LTC3777, by Analog Devices operates from input voltages above, below or equal to the regulated output voltage and had an efficiency of up to 99 per cent. The Power by Linear DC/DC controller has an input

Most of smartphones parts are made of silicons and other compounds, which are expensive and easily-breakable. This problem is making all of smart devices manufacturers looking for stronger and cheaper solutions. By combining a set of materials, a group of researchers have successfully discovered a new material which could finally finish the disaster of cracked smartphone
A New Material For Unbreakable Smart Devices Continue Reading
When [Mr. Sobolak] started his DIY Midi Fighter he already had experience with the MIDI protocol, and because it is only natural once you have mastered something to expand on the success and build something more impressive, more useful, and more button-y. He is far from rare in this regard. More buttons mean more than extra mounting
