I have a domain that points to a Heroku dyno running a Node.js web app. To facilitate sharing, I added Facebook Open Graph meta tags to the html headers. However, I could not get Facebook to “see” the tags in the Facebook Sharing Debugger using my custom domain, even trying…

Introduction Welcome to Web Development! It is a fun skill to develop and very manageable to do as a side hobby in your free time. I originally wrote this article to introduce web dev to my colleagues in the medical field. …

If you are an Arduino developer using the CC41-A attached to a ZS-040 breakout board with a non-functional STATE pin, this trick may be for you! Ok, admittedly, that sounds like a pharmaceutical commercial. The CC41-A is a Bluetooth 4.0 module clone of the HM-10 that can be used to…

Modifying the code to enable drawing by a hand in the air — Introduction In this final tutorial of the series, we will use the Leap Motion Controller to track finger motion in the air as it traces our Archimedes spiral. Refer to Part 1 and Part 2 for prequisite steps. Step 1. Install Leap Motion Controller Download the Leap Motion software to be able to obtain data from the…

Building on Part 1 to use a clinically validated test stimulus — Introduction In Part 1 of this tutorial series, HTML, CSS and Javascript was used to build a web application that tracks a mouse cursor position while a user draws a straight line between start and target points. In Part 2, we will build on the existing app by focusing on JavaScript…

Developing the app structure with HTML, CSS, and Javascript — Introduction Leap Motion controller is a low cost USB infrared sensor that can track position of hands, fingers and joints in 3D space. The device’s tracking reliability has been studied and is used in virtual rehabilitation projects (e.g. Putrino…

There is a saying that learning in medical school is like “drinking from a firehose.” I have also heard estimates that one learns [insert some large number here] of new words in medical school, but they were never substantiated by data. While in school at Ross University, I started thinking…

Introduction Electromyography (EMG) is a method to evaluate motor unit action potential activity in a muscle region. As action potentials (electrical signals) propagate through nerves to neuromuscular junctions, the change in electrical potentials (voltage) can be measured. …
