  • Single Pair Ethernet with MicroMod

    The SparkFun MicroMod Single Pair Ethernet Function Board introduces 10BASE-T1L Two-Wire Ethernet protocol into the SparkFun MicroMod ecosystem. Using the ADIN1110 Ethernet transceiver from Analog Devices Inc., this Function Board provides a development tool for long-range, 10Mb/s single-pair 10BASE-T1L Ethernet applications.

  • Watching the Earth move with a Raspberry Pi

    As someone who has spent a bit too much time nerding out over space and atmospheric weather, but never touched seismology, I decided it was time to dig deep and learn a bit more about the Earth.

  • Amiga 1000 Restoration: Audio Repair

    The first thing to check is the audio amp and filter. The unique thing about this is that it requires a -5v to generate some of the waveform. Guess what? -5v wasn’t there, instead it was +0.75v. That would probably explain a few things.

    Tracing it back the power supply was at fault here, and that may explain the audio chirp I heard every time the system was powered on.

  • Building a Budget Homelab NAS Server (2022 Edition)

    The server itself cost $531, and I bought four disks for $732, bringing the total cost to $1,263. It’s similar in price to off-the-shelf storage servers, but it offers more power and customizability.

    In this post, I’ll walk through how I chose the parts, what mistakes I made, and my recommendations for anyone interested in building their own.

  • Using The Force to open a door | Arduino Blog

    In the Star Wars Universe, the Jedi and Sith use The Force for battle and mayhem. But in the real world, people would use The Force for much more mundane everyday tasks. Obi Wan even does this in the prequel trilogy when he closes a door using the force. Star Wars fanatic Nick O’Hara leveraged an Arduino to replicate that trick.

    Despite his wishes, O’Hara lacks the midochlorians to actually wield The Force. But he has technology and that is almost as good. Automatic doors are already a thing, but they conveniently open anytime someone walks up—whether or not they possess The Force. O’Hara wanted his door to only open when he waves his hand. To accomplish that, he needed two things: some way to recognize the hand wave gesture and a method for opening the door.

  • The smart home is stuck in stasis (and I’m stuck in Dallas)

    It was clear back then that interoperability was going to be an issue. Making smart hardware necessitated new thinking about business models due to the cost of continued software updates and cloud computing. We were even talking about security and the lack of compelling use cases back then.

    These topics came up again and again this week, a decade later. Half a dozen panels mentioned the challenge of figuring out a business model that offsets the ongoing cost of smart devices.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
