CarbAlert - Part 1: Let Your Next Laptop Find YOU!

This is part 1 of a 4 part series of articles where I explain how I discovered and purchased my laptop by building a web application which scrapes a local PC parts forum and sends automated email alerts when posts featuring specific keywords appear:

Web inbox

CarbAlert is a web application which scrapes a local (South African) second-hand computer parts forum for new posts offering laptops featuring keywords of interest (specifically the first page of the “laptops” forum) I’m using Django for the admin console and database/ORM integration, Scrapy for web-scraping, Celery for task management, Flower for task monitoring and Mailgun for sending out alert emails. I am using Docker to manage and run the containers which make up the CarbAlert application.

NoiseBlanket: Arduino White Noise Player with IR Remote Control

Overview After a recent sinus/ear infection I began to experience tinnitus. In my case it presents itself as a constant high frequency static hiss/whine in my left ear. It’s been about a month since I first noticed it. Hopefully it will eventually disappear. During the day when I’m at work or around friends I don’t really notice it. However when I’m in a quiet room, such as when falling asleep or in the early morning after waking up, it is quite noticeable and distracting.

A Python wrapper for the Adafruit USB/Serial LCD Backpack

Overview I’m working on a project which requires a character LCD to work with a Raspberry Pi. A character LCD is thing displaying the text in the image above. The one I am currently using is a “green backlit 16x2” character LCD. This means that the display is capable of displaying 2 rows of 16 characters, and it features black characters on a green background. There are various sizes and colour combinations (text and backlight) available.

Adding Hugo version and commit information to a status page

As described in a previous post, I have set up a GitLab CI runner to build and deploy this blog. For obvious content changes it is easy to see if they have been applied - I can just visit the site itself. For changes that are a bit more “behind the scenes” it may not be so easy to determine if and what changes have been applied. For example: updating the version of Hugo used by the GitLab CI runner to generate the site.

Domain Name Change

FYI I have decided to “re-brand” this blog under my own name. I have 301’d all the server blocks for practicalmagic.co.za to point to dinofizzotti.com. I also promise to actually blog more often (sorry).

Automated blog posts with Hugo, GitLab CI and Docker

…or how this blog is built and deployed. Introduction I’m using the tools and methods described in this post because I wanted to learn more about Hugo, GitLab CI and Docker. I don’t claim this is the best way of combining these technologies, or that everyone should do it this way. I wanted to create a blog and publish content in a way that felt fun, and at the same time learn something new.
