Some months ago I wrote about installing Unifi LEDs in my office. It was an interesting project figuring out how to fit LED panels meant for a suspended ceiling in a big office, to my little tiny room. But it worked well, and I have since had questions on how it works and how I did it. In response I made a short video explaining the whole setup. 🤓
Have you ever wondered just how a USB security works? Yeah, I did too for the longest time. I just couldn’t get my head around why it was more secure, more convenient, or just better than other multifactor authentication options. So, Yubico sent me two YubiKeys to test out, and I made a video out of it, which is below.
TL;DR: USB security keys are harder to compromise than authenticator tokens (in an app), and easier to use as you just touch them when inserted. Anyway, find out more in the video 😊
I installed Unifi Access some months ago, both to add some security but also because swipe cards. Why would I not want that on my office? Anyway, Unifi Access does a whole bunch of things, some of which I don’t use with a single door lock, but also some that I keep getting questions about. So, as an add-on to my first installation video I thought I’d do a full run-through of what you can do with Access. Enjoy.
As most IT nerds are destined to do, I also support my family (which means I mostly fix their printers). I thought I would do some more in-depth support and organised for an Amplifi Alien system to be sent to my brother in Denmark. He is not a technical person beyond using a phone and hooking up a home stereo, so it was an interesting experiment to see how easy Amplifi is to set up.

I have been getting into Home Assistant for automating and optimising the infrastructure on my farm for about a year now. One of that main reasons to initially investigate how to do this, was to monitor my water tanks. I have no town water connected, so I rely on rain water tanks and a bore/well for backup. Living in country Australia, it is east to suddenly use way more water than you think due to washing, pool filling, garden watering, leaks and much more.
The tanks are dispersed on the property, so checking them manually requires lots of walking, climbing, lifting and finagling. Having sensors showing levels, remote on/off for pumps and logic to automate it would save time, money and water. It took quite a while to figure out which solution to implement, but I ended up with pressure sensors/conducers to get a water pressure reading, then convert that to litres using mathematics. It was quite a journey, and the hardest to figure out was the house tank, as it is an in-ground tank. Measuring pressure at the bottom of it is tricky.
In any case, I documented the whole journey in the video below. Hope you find it helpful and leave a comment if you have a comment or question. 😊
For the past year I have been upgrading, expanding, testing, configuring, adding and breaking my farm WiFi setup. I have been using Ubiquiti equipment, mainly from their Unifi range, and it has changed how I work, how I play and how I use my network day to day. It has upgraded my professional work with better lighting, more stable connection and removed one uncertain element of country living. For me and my family it has genuinely changed our ability to communicate with family overseas, our local community, our volunteer projects and schools. Most importantly, it has increased the safety of working on the farm outside, as we have no, or very limited, mobile signal. We can now call and communicate in general almost anywhere on the farm (and get those important tweets out!)
When I first started changing my WiFi devices it was to get rid of repeater points mainly, but I also had a bunch of other reasons. I didn’t expect it to have this much of an impact, nor that I would enjoy nerding out over networking equipment that much. But I have.
So far I have covered roughly 30 acres (12 hectares) in stable WiFi, built Llamacam and installed swipe card access to my office, which is made possible by the following gear:
- Dream Machine Pro
- Unifi Switch 24 PoE
- Unifi Swithc PoE+ 24 (250W)
- Unifi Switch PoE 8 (150W)
- Unifi Switch Flex
- 2 Unifi Long-Range Access Points
- 2 Unifi Flex HD Access Point
- 3 Unifi Mesh Access Points
- 1 Unifi In-Wall HD Access Point
- 4 Unifi nanoHD Access Points
- 7 Unifi Protect G3 Flex Cameras
- 1 Unifi Protect G3 Bullet Camera
- 1 Unifi Protect G4 Bullet Camera
- 1 Unifi Protect G4 Pro Camera
- 6 airMax NanoStation AC 5
- 2 NanoStation 5AC Loco
- 1 SunMax SolarPoint
That is a massive list, when I see it like that. It has been a very incremental journey, so it kinda blows my mind to see where I am at now. And because of that, I made this video to give you the tour of the farm and how it is all connected. Enjoy.
I am getting into home automation big time. I am loving the learning process, the tangible result and nerding with all sorts of processes. Most of it involves networking components, programming, new gadgets and an improvement of my every day life. All things I value very much.
In general I am looking for one or more of two principles when I install IoT devices or home automation
- Save me energy, time or money. There should be a measurable saving somehow that justifies the often many hours of work.
- Add a function or feature I am missing and would use regularly.
As tempting as it is sometimes to install something “just for fun”, it is most likely a waste of time. This time I needed lights in my server cupboard (which is just a cupboard that I happen to put the server cabinet in) and I figured I could automate it with Home Assistant and automation. I used a Govee Light Strip, an Aqara door sensor and community integrations in Home Assistant to get it all happening. Check out the video below.

In December 2019, I got my hands on the 7th generation of the ThinkPad X1 Carbon laptop. This was, at the time, the premium Ultrabook in the X1 line, and I was giddy as a llama in a heap of freshly cut tree branches. It was an exciting moment, and I was over the moon. However, after a full year of using the machine every day, how does it hold up? Read on to find out.
To continue my journey into amazing WiFi coverage and farm automation, I installed a Unifi In-Wall HD access point. This is a neat little device that provide both wireless and wired connections. I fit perfectly into the part of my farm homestead I am renovating, giving more WiFi coverage as well as provide wired connection for a future TV, Xbox and PlayStation that will live in this room.
The install and setup was really very simple, and I documented all of it in the video below.
I’ve been wanting to upgrade the security on my farm for quite some time. I’ve written about setting up cameras before, and when I discovered that Unifi has an Access product, which includes door locks and swipe cards, I wanted to get that onto my office. There was a lot of wiring experiments, broken parts, drilled holes and bird poop to get through, but now it works!
I decided to create a video guide for the setup as I went along. I genuinely had no idea how it would turn out when I started. Watch below to follow along with my journey.
