Linux, Hardware, Software and Chaos. What more is there?
Here’s some instructional tutorials on how to accomplish some really neat tricks with hardware or software, Linux or Windows.
In Part 1, I discussed the research, physical installation, a bit of maintenance, and the overall basic operation of the Generac 22kW Guardian whole home generator. In this post, we’ll go over the monitoring of the generator and quickly outline the vendor’s supplied option as well as the Open Source option I decided on, and even up contributing to! Yes, even though I’m not a developer, I managed to contribute to an Open Source project and helped the developer out!

So, if you’re a Texan, you already know who ERCOT is and you already know what’s going to happen in the next few days. If you’re not Texan, or you haven’t been eyeing the weather, it’s going to freeze. If you’re not sure what the connection to freezing weather and ERCOT, I’d recommend reading up on it here: Wikipedia This quick hack article isn’t about them per se, but something that might be helpful to keep an eye on the grid in the upcoming winter storm.
Comments closedTo set the scene for this quick hack, I needed an MSDOS bootable USB drive so that I could flash firmware for a FreeNAS box…

Everyone knows that in most if not all devices, batteries are considered a wear item, an item that’s designed to be replaced at certain intervals of a machine’s lifetime. (Ok, unless you’re Samsung… or Apple… or any one of a bunch of stupid laptop vendors) Enterprise level servers are no exception. What is outrageous though is these consumables are usually stupidly expensive and can be repaired for much less than the replacement part. In this case (and this post), I saved myself about $63 by building my own replacement battery pack for my HP SmartArray P400 raid card.

It might not look like much, but the switch used as this feature image has more to offer than one would think judging by appearances. In this article, we will be converting a “stupid” switch into a “smart” switch for the purposes of controlling a connected GE Light Bulb over Z-wave and discuss why you’d want to look for a stupid switch for smart devices in the first place.
Everyone knows that I love a bargain. That love for bargains is intensified any time networking gear is involved. Imagine my excitement when I found a bunch of the above pictured Cisco access points on Ebay for around $8 a pop because the lid won’t stay on. Unfortunately, my excitement was tempered a bit when I found out that these were designed to work with a controller and weren’t stand alone units. Undeterred by this disappointment, I researched and found a way to get these things to operate on their own as standalone units and freed them from the hive mind! In this article, we will cover converting the Cisco AIR-AP1131AG-A-K9 from “Lightweight”(controller-based) to “Autonomous”(standalone) and will even cover how to put them back in “Lightweight” mode if you want later on.

Quite some time ago, I posted an article on how to build a basic Minecraft Server which served to get you up and off the ground with multiplayer gameplay. It’s been two years since that article was posted and there have been so many advances in the Minecraft Server realm from administration changes (now you have a fancy GUI) to core game changes that allow for the modification for just about everything gameplay related. Popular alternative servers (Bukkit, Tekkit, Feed The Beast, etc..) allow for mods to be used which can drastically expand your Minecraft experience. This howto will detail the process going from a basic Debian server installation to a fully fledged vanilla Minecraft server with a browseable map. Read on for the full article, it’s pretty long but we have a lot to cover.

Have a giant Arduino powered killbot, but can’t fancy being right next to it when you unleash it on the unsuspecting populace? Want to change the mood-lights in your dorm without having to get up off the couch? Why not use IR remote controls to do the walking for you? In this article, I will be covering how to use the IRremote Library written by Ken Shirriff for the Arduino to control a seven segment display as a proof of concept. Killbot not included.

The Internet as we know it is undergoing a significant change. With the last IPv4 addresses being allocated out, the Internet has officially run out of address space. IPv6 is the next-generation IP addressing system that aims to resolve this issue however the changes proposed are drastically different than the current IP schema currently in place and for most is quite a daunting task to switch. In this post, we will cover some basic IPv6 information and some fundamental differences between v4 and v6 (aside from tons of IPs), and finally we will build out a pfSense firewall with IPv6 using pfSense and a free IPv6 tunnel provided by Hurricane Electric. Read more to get started on the cutting-edge of Internet infrastructure.
After publishing the last post on networking and the security series, I felt it was necessary to go ahead and publish a piece on building a custom router. I have been a fan of pfSense for the past four years and swear by it. It has the ease of use of a commercial GUI-driven router and unrivaled flexibility limited only by the hardware it is installed on. In this howto article, we will cover installing pfSense on an embedded platform and initial configuration for getting your router up and running.
