During the course of the day I encounter lots of challenges, some of which take minutes to solve and others that take much longer. My goal for this section is to keep track of these challenges and their solutions. I will turn the longer ones into articles, while the shorter ones will stay as blog entries. You can expect topics to range from very specific programming challenges to broader topics like life.
Below is a list of the recent blog entries. You can also browse the blog by using the tags on the right side, or if you know what you are looking for then you can use the search box at the top right.
I have recently been training for my private pilot license. After learning the basics, I really enjoy using ForeFlight for tracking and planning. ForeFlight also makes it easy to track my progress towards the license. One of the requirements is to do a solo cross-country flight. When it came time to log my entry in ForeFlight, I couldn’t figure out how to do it initially. I finally figured it out and this blog post shows how to do it.
I have recently started playing around with Hive OS. The miner kept failing to connect with the default setting in Hive OS portal. Sometimes it would say things like “Connection Remotely Closed by usw-eth.hiveon.net” and after some tinkering, it started giving some generic errors like “Operation canceled.”
I have recently been training for my private pilot license. As part of the whole experience, I also setup a simple flight simulator using Microsoft Flight Simulator 2020. It has been a good supplement for my training, definitely not the same experience, but it can help with better understanding VOR navigation and other similar concepts. I haven’t run the simulator in about a month and a half, and when I started it up I got an error message saying that there was some mandatory update that I needed to install from the Microsoft Store. Going to the store didn’t show any updates so I had to do some digging to figure our what was going on.
I have recently been playing around with a side project that uses the ESP32 SOC/microcontroller, the Adafruit Huzzah32 flavor specifically. I am controlling a motor with it and use a ULN2003 to drive it. I noticed that when I connected the driver, I couldn’t upload a new firmware to it. After doing some troubleshooting and research, I learned that my pins were the issue.
Specifically, GPIO PIN #12 was the issue for me. It’s one of the strapping pins used for the different boot modes. I am sure there are ways to address this, but I ended up switching to a different and now I can upload firmware as needed.
I have recently been playing around with 3D printers. I wasn’t sure if I would like them or use them enough, so I decided to start with a common basic 3D printer: Creality Ender 3 V2. I was surprised to see how much I ended up using it. I wanted to turn the printer off automatically when it completed a print, but there wasn’t anything standard. So, I researched and put together this solution for my specific setup.
I recently decided to build a new desktop computer for a new hobby that requires a powerful Windows-only computer. I thought I would spend 1-2 weeks researching, and then I should be good to buy and be done within three weeks. Was I wrong?!
In March of this year (2020), when the Coronavirus disease (COVID-19) pandemic was getting into full flux in the US, I, along with other volunteers, started an initiative to help with grocery and other essential item deliveries for at-risk population. With volunteer developers’ help, we launched right away. Later, we successfully concluded this initiative at the end of May once commercial services and grocery stores caught up to the delivery demand surge. This page hosts the last remnants of that effort, and the cv19assist.com domain now redirects to this page.
It has been a while since I have had to set up a new MacBook Pro so I forgot about all the small things that I had changed over the past few years. I have some interference issues at home that I am still trying to resolve, but in the meanwhile I set up a second slightly older access point that I had lying around. I noticed that my MacBook Pro wasn’t switching when it got closer to the second access point (AP).
I couldn’t resist the Tesla fever and finally took the plunge a few months ago. Since then, I have been absorbing the Tesla ecosystem and observing everything that it has to offer. I have been especially intrigued by the Autosteer (part of “Autopilot”) functionality because that’s one of the game-changing features that Tesla is offering. Here are a few odd behaviors of the system that I have observed so far. Note that most of the Autopilot features are currently in Beta, so I am always careful when using it, and I am also expecting that Tesla will work out these kinks as it continues to improve the system.
