I started using Vim in earnest about two years ago, and it has become my main text editor since. But before you dive in you should know the learning curve is steep but it comes with powerful capabilities. I won't go into all the pros and cons but I do want to share how I… Continue reading VIMRC File Configuration
Ever seen those beautiful images Real-Time Spectrum Analyzers produce that show the FFT as an intensity graded persistence display? Well, I wanted to create a plotting tool that would allow you to create high-resolution static imagery for signals. There is already an amazing tool aptly named Fosphor for GNURadio that is capable of real-time plotting… Continue reading Python Intensity Graded FFT Plots
Learning how to solder with hot air and solder paste is definitely one of those skills that you need to practice in order to built and fix modern electronics. The perceived difficulty of soldering SMD components has scared me in the past and has prevented me from learning more skills like PCB design, because why… Continue reading Hot Air Reflow with Solder Paste
Diving deeper into antenna design you find really interesting antenna structures based on what parameter you are trying to optimize for. I was looking for antennas that had wide bandwidth and some directionality, to use in conjuncture with my LimeSDR Mini for one of my many projects, that's how I found out about the Vivaldi… Continue reading Vivaldi Antenna Design with MATLAB
The competition, along with its organizers, look to set a new standard in wireless efficiency and durability. This is done by providing a simulated wireless environment and scoring structure that challenges competitors to build resilient and reliable radios. More detailed information can be found on their website. https://radioresilience.com/ The Radio Resilience Competition debuted at the… Continue reading Radio Resilience Competition
I created a shared drive on my network on my Unraid Server that I have set up to display photos with Plex. I wanted an easy way to upload photos from my phone to the server, there is the ability from within the iOS Plex app to do so but it requires a monthly subscription… Continue reading Save Photos To Shared Drive From iPhone
I first learned about the Unraid OS from a Linus Tech Tips videos where they set up multiple gamers to use the same PC, at the same time, with virtualized OS and separate dedicated GPUs for each person. This really sparked my interest not because I am a huge gamer but because of the possibilities… Continue reading Unraid VM Server
I wanted to create an electronics bench computer that could be set up to control logic analyzers, GPIO, software-defined radios, and other equipment for running tests and diagnostics on my various projects. Decided to use the Raspberry Pi 4, because it is small and compact, has various IO capability, can be paired with a touch… Continue reading Raspberry Pi 4 Bench Display
A while back I read about a project on Hackaday that a hacked an expensive indoor smart bicycle, where the virtual riding ability was axed when Peleton bought the company, to work with the popular service Zwift. They did this by capturing the proprietary Bluetooth output, reformatting it, and sending it on as a generic… Continue reading Arduino BLE Cycling Power Service
This is the last day of technical conference talks so its packed to the gills with content. There is also a closing talk with Ben Hilburn and Derek Kozel where they close out the conference with a bunch of information. Along with a reveal that all or almost all of the workshops have been recorded… Continue reading GRCon20 Virtual Conference Day 4
