Overview: This is the third generation of our succesful SODAQ ONE board. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. It has the Ublox Eva 8M GPS module which is not only miniature but with it’s assisted GPS feature it can get a fix within seconds. We’ve now […]

This is a tutorial for making the Tidal Clock. The clock shows the ebb and flow between high and low tide by a rising and falling water level. It consists of an airtight acrylic container that has a front visible chamber and a back hidden chamber. A volume rotates through the back chamber, displacing the
I designed this project for a 10-hour workshop for ChickTech.org whose goal is to introduce teenage women to STEM topics. The goals for this project were: Easy to build. Easy to program. Did something interesting. Low-cost so participants could take it home and continue to learn. With those goals in mind, here were a couple

Nowadays, there is a lot of technology that implements wearables in fashion, medicine, worker safety, accessories and much more. Many wearables are coupled with uncomfortable charging cables that are irritating for users to handle, some even have big batteries that make wearables a burden instead of an advantage. Statistics show that people tend to abandon

In this project I will describe the construction of robots standing in equilibrium with Arduino.We explained in our previous version of the android controlled project. In this project we will move to our control. Let’s go let’s get to our building project. Step 1: Materials: Arduino Uno or Mega L298 Motor Driver Card 3 Piece

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy! A version of this tutorial is also on my

One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It

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

Intro 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 endurance of the power supply, as most of the designs out there are using slow components. However, I
