Home office ventilation — controlled by CO₂ level

Home office ventilation — controlled by CO₂ level

I recently watched Jeff Gerling’s video on CO₂ levels, and how to monitor it. My home office is also in the basement, with no windows. So I paid attention to the air quality when setting up down here.

In addition to monitoring the CO₂ level, I’m also automatically ventilating the space when the air quality gets too bad.

Troubleshooting the garage access point

Troubleshooting the garage access point

Ever since I ran a underground CAT6 to my garage — my Unifi UAP-AC-M access point have been acting strange…

I initially noticed that whenever I was close to the garage; I would loose internet connectivity for a few seconds. At first I just thought it was an area with poor coverage, but looking at the signal strengths that didn’t make any sense.

Reddit traffic spike and website performance

Reddit traffic spike and website performance

On Tuesday August 24th I posted a link to my Running underground CAT6 to detached garage post on the r/homelab subreddit. The Reddit post got lots of upvotes and comments — and started climbing on the r/homelab front page.

This generated a spike of traffic like I have never gotten before. In this post I’m going through some numbers; like performance, traffic and cost.

Deploying this Hugo blog to AWS S3

Deploying this Hugo blog to AWS S3

This blog is built with Hugo — an open-source static site generator. Static websites require no server side processing, which makes them easier to host and opens up new hosting possibilities.

There are many options out there, but I deploy my website to AWS S3, using CloudFront to distribute it globally (aka. make it fast).

Here is the why and the how.

Altibox fiber — straight into Mikrotik CCR1009

Altibox fiber — straight into Mikrotik CCR1009

Ever since I got the fiber installed last year, the plan has been to drop the ISP box and plug it straight into my router. That’s why I had the fiber terminated in my patch panel.

I’ve been reluctant to do it, since messing with the internet needs to be done while the rest of the house is sleeping. And I was unsure what SFP module to use. I did buy the Ubiquiti UF-SM-1G-S pair, planning to use it with my EdgeRouter.

But I ended up using the SFP module that came with the ISP box, and my new MikroTik CCR1009.

The swap was super easy and only took a few minutes 😃

Getting started with MikroTik CCR1009 and RouterOS

Getting started with MikroTik CCR1009 and RouterOS

When I began replacing my Unifi switches with MikroTik — I was very impressed with the MikroTik devices. So when I found a CCR1009-7G-1C-1S Core router, second hand, for a reasonable price — there was no reason not to buy it.

RouterOS seemed daunting at first; so I watched a lot of YouTube videos from The Network Berg, which increased my confidence 🙂
