We recently got a family computer in our play room, and it of course needs network. So I ran a 20 mm conduit from the basement, through the kitchen, to the play room, and pulled two CAT6 cables.

Shortly after I upgraded my Unifi access points from 4.3.28 to 5.43.43; I started getting timeout issues. Not all devices, but some; the Raspberry Pi driving our DAKboard, and both our Netatmo air quality sensors.

It took me a while to understand what was happening, and I didn’t immediately relate it to the firmware upgrade.

When I got serious about my electronics lab — I found it useful to see what equipment other people have in their labs. I got a lot of information from EEVblog’s video on How To Set Up An Electronics Lab.

So — here is my contribution 🙂 Below you’ll find a list and photo gallery of my electronics lab equipment 👇

Earlier this year I put up a Raspberry Pi powered DAKboard display. It shows photos from our Google Photos albums, the time and weather, and most importantly; our shared calendar.

But I’d like it to show some custom data as well — like indoor temperature and humidity. And the measured outdoor temperature, not just the one reported from the weather service.

Here is how I did that — using Home Assistant 👇

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.

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.

I’ve written a few posts now about my Home network v2 project. What’s the plan? Let’s go through that now.

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.

I’m adding security headers to my S3 and CloudFront hosted website — using Lambda@Edge. It’s pretty easy, here is how 👇

I dug a 10 meter trench to get wired network to my detached garage. Then installed a rack cabinet and PoE switch. Here is the build log 👇
