Terraform’s null_resource resource can be useful when there aren’t any existing modules to satisfy your needs (with some caveats). Hashicorp’s documentation for it is a bit lacking, but fortunately there’s more information about the provisioners in their other docs here. After using these resources in a handful of...

Cloud Functions are an easy, performant, and potentially inexpensive way to build serverless backends. I recently went down the route of setting up continuous deployments for them, and thought I’d share my learnings with it. The easiest way to deploy a Cloud Function is using the gcloud CLI like so: gcloud functions...

Featured on Hackaday! A few years ago, I had the idea to track my sourdough starter using computer vision. It was neat to monitor it this way, but it was fairly impractical to do for each feeding since it required setting up a camera, downloading the images, and doing some manual image cropping before running it...

Back in 2018, we decided to raise chickens in our urban backyard, all in the name of being able to have fresh eggs every morning. Our city had bylaws on having chickens, which included: A maximum of 4 hens (no roosters), 4 months or older Ducks, turkeys, or other livestock are not allowed Eggs, meat, and manure...

A few years ago, I created a tutorial on setting up Visual Studio Code for development with the STM32. Since I’ve also been developing on the Nordic nRF52, I thought I’d share another tutorial to show how a project can be set up, flashed, and debugged using Visual Studio Code. The template project discussed in this...

Featured on MagPi Issue 72, Hackaday, Hacker News, Adafruit, Hackster.io and The Guardian! Bread, the quintessence of life. People have survived for centuries off this staple consisting only of flour, water, salt, and yeast. Try consuming all these ingredients separately, and you’ll be in for a digestive surprise....

In case the title wasn’t clear, this blog post is about developing a web application using the Python programming language using Jupyter Lab, Flask, and the Heroku platform. If you were looking for an article on python recipes, you can start off with this one on making a poached Burmese python curry. The Backstory...

As a mechatronics engineer (in training), sometimes I like to pretend that I also know how to program. In my most recent adventures to software land at MistyWest, I needed to write an application in C# that involved doing a ping sweep to find devices that were physically connected through ethernet. Since Google and...

Disclaimer: Light therapy is one method of easing seasonal affective disorder (SAD); some people swear by it whereas others remain unaffected. This blog post does not intend to refute the effectiveness of light therapy, but rather to dig deeper into the technology behind these light therapy lamps to better educate...

Visual Studio Code’s combination of functionality, customizability, and aesthetics makes it one of my favourite code editors. As such, I was set on making it work with embedded development since I was getting started with the STM32 line of microcontrollers. I was following the steps outlined in Mastering STM32 by...

Featured on Hackaday, 3D Printing.com, All3DP, and Fictiv Blog. Also cited in a few research papers1, 2. Yep, you heard it right. With all the craze surrounding cooking sous vide these days, it was only a matter of time before someone decided to venture using it outside of the culinary world. Turns out that someone...
