Tech Tidbits & More

Welcome to the Internet Home of John M. Wargo; I created this site back in 2009 so I could post articles about things that interested me. Herein you’ll find articles on a lot of different topic areas: Mobile development, Web development, Internet of Things (IoT), and a lot more. Every time I learn some new technology or complete some cool or interesting development or IoT project I publish an article here.

You’ll also find information about my books, source code projects on GitHub, and articles published in or on other sites or magazines, even videos of my many conference presentations or project demonstrations. I’m also especially fond of the series of Stupid Developer Tricks posts.

You can view all articles in reverse chronological order, or you can find articles by category. Of course, if you can’t find what you need in those views, use Search to find anything anywhere on the site.

    Over the US 4th of July holiday, we were hanging around with family when my sister in law mentioned that she wanted to get an Owl House for her back yard in order to attract an owl to live in her yard. I'd never made an Owl House before, so I quickly volunteered to make one for her.

  • Generating Post Descriptions Redux

    Date: Posted Monday, July 1, 2024 at 09:04 PM  | Categories: Artificial Intelligence

    AI Generated   I recently published a post about 3D printing but forgot to set a description. Luckily, I used the Describer GenAI extension for Visual Studio Code to quickly generate a description for me. It only took a few clicks and seconds to add a nice description to the post before publishing it.

  • 3D Printing Paradise

    Date: Posted Monday, July 1, 2024 at 08:40 PM  | Categories: Project Builds

    AI Generated   I bought a 3D printer during the pandemic but struggled with it, so I upgraded to a P1S printer from Bambu Lab. The new printer is enclosed, self-leveling, and fast, making it easier to use. My daughter loves using it for cosplay projects. I also bought a lot of filament and have been impressed by the quality of free models available online. I recently used the printer to create a wooden enclosure for a T5 e-Paper display unit, but had to find a 3D printer plan for a better fit due to the unit's design. The prints turned out amazing, and I'm excited to see the final result.

    Date: Posted Thursday, June 20, 2024 at 05:07 PM  | Categories: Flutter, Mobile Development

    A while back, while anticipating a particular event (my retirement), I decided to create an app that allowed me track the number of days until the event. One thing led to another and I decided to create a more generic version of the app so I could write about it here.

    In my previous post, I mentioned that I like building electronic projects I find online. Historically, I purchased a lot of project components from online vendors like Adafruit and Sparkfun. Both offer their own proprietary boards as well as some standard electronics components you can use for your projects (such as battery connectors, cables, breakout boards, other connectors).

  • Bench Power Supply Project

    Date: Posted Sunday, June 16, 2024 at 02:12 PM  | Categories: Project Builds

    I'm a big fan of Instructables and regularly watch their newsletters for interesting projects. A few weeks ago, one of them caught my eye: Lab Bench Power Supply. This project seemed cool so I decided to build it.
