Continuing on from my previous post about Meshtastic , I started Meshing around (see what I did there?) with the LILYGO T3 S3 V1.3 . NOTE: I received this product for free (minus shipping) from LILYGO in exchange for feedback. Why this one? As mentioned in the previous post, I have a T-Deck Plus and I was impressed with the build quality. It was not ideally suited to be a permanent station node…
Introduction to Meshtastic Because ACARS and ADS-B wasn't enough tinkering with electromagnetic emissions, I've gotten into Meshtastic . That link should cover the basics but for a TL;DR, Meshtastic is a standard that uses unlicensed frequencies (915MHz in the USA, 868MHz in Europe, and others) to send small packets of digital data in a decentralized wireless mesh. This is useful in emergency…
Since my last post about picking up ACARS messages I've made more progress, enough to warrant another post! Let's dig in. ACARS Since last post, I've added 2 more receivers - one more for ACARS and one for VDLM2. It was pretty easy to add the additional containers . This increased spectrum coverage helps ensure I pick up juicy messages. Antennas I added a metal plate and attached small a magnetic…
I've been interested in @ACARSDrama on Mastodon for a while and I sent a message to @SecureOwl (Mike, the operator) offering to help pick up messages to feed the bot if he ever went in that direction. He later invited me to help out and put out a public invitation and thus began my ACARS/VDL2/SDR (Software-defined Radio) adventure! What does it look like? Not much, really. Just a computer with a…
Information and Background (Skip to the "How-to" section if you're already familiar with these computers) Dell 7010 Plus is a computers with 13th gen Intel processor that comes in a very small form factor and are quite easy to work on, with a max of 64GB of DDR5 RAM (possibly 128GB, but 64GB SO-DIMM sticks are unobtainable by me) and two M.2 slots. As you can see, there is 1x Gigabit Ethernet, 4x…
Background and motivation Many people use tools like Terraform, Ansible, custom boot scripts and more to provision and maintain their Kubernetes nodes. These tools are powerful but they do have a downside of only partially achieving what should be the ultimate goal: declarative configuration with an immutable OS. Talos is a great, popular tool that can step in here, but unfortunately Talos is a…
Currently, my Kubernetes cluster is running on Ubuntu 20.04 and my upgrade path to the latest LTS 22.04 is dicey. So I figured it's time to look into immutable OSes. There are a few to pick from, Talos , K3OS , Kairos are popular ones. Talos seems to be the most popular, and K3OS is used pretty often (though it seems the momentum in the project has slowed). Oddly, Kairos doesn't have much written…
Information and Background With many thanks to Perihelion in the k8s@home Discord. (Skip to the "How-to" section if you're already familiar with these computers) Dell 7040s are computers with 6th gen Intel processors that come in a very small form factor and are quite easy to work on, with a max of 64GB of RAM, an M.2 slot as well as a 2.5" SATA port. They are quite powerful and refurbished units…
The Problem If you're like me, the prospect of being able to hit Kubernetes resources from your local network (and expose them to the Internet to host apps, games and other services) is very alluring. There are many ways to do this, one of the most popular being MetalLB . MetalLB is a fantastic app, and it served me well for years but I always wanted to do things the "right way". In the "easy…
Background I recently decided to try out Ubiquiti after hearing many of my friends and people on social media (Discord especially) speak highly of their experience. On a previous project for replacing my NAS, I did all my own research, bought an Asustor NAS, ended up making a lot of mistakes and ultimately also discovered that that device was not a stable enough or easy enough to use. After…
