Intro to GPS With Microcontrollers

https://youtu.be/_Qog6ofGD5Y Once the purview of strictly military operations, GPS has become a regular part of modern living and in relatively short time! Who wouldn't want want to know when and where they are anywhere on the planet? It's a science fiction dream brought into reality, one now so woven into our lives it seems almost trivial. The demand for precise positional data built into planes, ships, ca ...

MyPart, An Open Source Portable Air Particle Counter

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 is also useful in understanding the cleanliness level in a controlled environment. Ai ...

InstaKISS : Networked Picture Frames

These frames are connected to the internet, which allows you to instantly send a kiss to a loved one. When my boyfriend and I were in a long distance relationship (for one and half years!), we communicated anyway that we could. We talked on the phone, sent presents and cards, fought through text and would leave our webcams on while sleeping so we knew the other was there if we needed them. We communicated t ...

PCB layout design with DipTrace – An overview

DipTrace is a sophisticated schematic and PCB layout software. I had it installed on my computer for over a year but have never really used it. Since I needed a super simple PCB for some 78XX / 79XX type linear regulators, I decided to use this opportunity for my first steps with DipTrace. DipTrace offers different prices for different packages [1]. The cheapest version, DipTrace Starter (300 pins, 2 signal ...

Make Your Own Motorized Camera Slider

In this project I will show you how I repurposed two old camera tripods in order to create a motorized camera slider. The mechanical system consist mostly of aluminium and stainless steel which makes the slider sturdy and pretty decent looking. The electrical system consists of an Arduino Nano with LCD, rotary encoder, limit switches and stepper motor. Let's get started! Step 1: Watch the Videos! https://yo ...

Design and Implementation of a 12 Lead Portable ECG

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 at the end of this post and includes background inform ...

High voltage supply (10-30kV) made from CRT television flyback transformer

Old CRT monitor or TV is a great source of electronic components that can be used in DYI constructions. One of them is a flyback transformer that can provide 10-30kV output. The input voltage can be in a range from a couple of volts to over a dozen of volts, power consumption is a couple of watts. In my construction input voltage is 9V, power consumption is 5W. A flyback transformer is driven by one or two ...

Arduino Weather Station using DHT11

Introduction Using a display to view the temperature and humidity of your environment can be possible using the DHT11 or DHT22 sensor with the easy to use Arduino microcontroller platform and that’s the goal of this project. For this project, we will be using the 16×2 LCD display module to display the temperature and humidity readings gathered from the environment using the DHT11 temperature and humidity se ...

Open source 12V powerbank

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 charging a higher-end tablet with 12V input, does not exist cheaply. Looking around for 12V power banks yields ...
