• 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 add sudoers in Debian | FOSS Linux

  Sudo stands for superuser do. It is a command-line utility that permits trusted users to run commands as another user by default root. When prefixed with any command, the superuser temporarily gives another user rights as an alternative root. If you, for instance, want to access any system-related setting or, rather say, update a system or edit system files, you must log in as a “root” user in Linux. Ideally, root users have the right to perform any system task. However, sudo privileges can also be assigned to other users to act as a root. The basic philosophy is to give as few privileges as possible but still permit users to complete their work. Additionally, sudo is an effective way to log who ran which command and when. It is also advised to utilize this command carefully as it contains all the admin rights. As such, any misuse of the command may lead to severe damage to the system. In the latest release of Debian, version 11 (Bullseye), the sudo user’s info is stored in the sudoers file, located in the “/etc/sudoers” directory.
