MDNS Across Unifi VLANs

I started working on some hardware projects related to home assistant using the ESP8266. in working on these I learned that the ESP devices use mDNS to advertise their hostnames for communicating with them. My devices however are on a separate VLAN that’s unable to communicate with the internet, and that VLAN was also blocking the mDNS updates from making it through to home assistant, keeping it from being able to know the hostnames. I could use static IPs for this, however I want to avoid locking all my little smart devices to static IPs.

EspDeck: Home Assistant Macro Pad

After seeing some posts with EspHome and Zigbee keypads, I realized I wanted to make one too. I wanted the ability to easily trigger more complex actions in home assistant that I don’t have an easy way to fully automate. I decided to make the EspDeck project to provide construction and technical details on building one of these macro pads. EspDeck provides a 9 key macro pad supporting single, double, and hold click actions on every key and can be integrated with home assistant easily through the ESPHome integration or add-on.

Network Rack Upgrade

I recently needed to build out a new network. The new network had a box in place that I could use for gear, however that box wasn’t big enough for any rack mount gear. I decided to mount a rack over the top of the box to handle all of the gear and keep it organized. With the new network, also came with a need to expand the number of switch ports I have available. I set it up to drive POE to all the end points so that I could have better centralized power.

Proxmox VM Misconfiguration Downtime

I’ve got a VM running a critical service on my Proxmox host. This VM doesn’t have any real data to speak of, it just runs a few automated tasks that we rely on, so the virtual disk is rather small for it. For some reason while working on the VM (likely restoring a backup from a previous problem I had), I must’ve restored the VM and made my NAS mount the location of the virtual disk. So my virtual machine has been running off my NAS for a while. Until one day, when I had to bring my NAS down for an extended period, and the service went down too. I spent a bit of time trying to get it back up before realizing that the disk was located on the NAS and the NAS wouldn’t be up for a while. Nevertheless, once the NAS was back up, I moved the disk back to the virtual host where all the other VMs run from… oops.

Server Rack Repair

I noticed a bit of damage on my server rack recently. The top of it is starting to crack around two of the screws. This isn’t good as it undermines the integrity of the rack and could cause problems in the future, and so I had to fix it. The lid was crushed downwards, likely due from a heavy object sitting on it (more than likely my NAS sitting on it at some point in time).

Upgrading Ubuntu Host for Unifi Controller

My unifi controller was installed on an Ubuntu server back on 16.04 LTS. This server finally reached end of life and I needed to run an upgrade to Ubuntu 20.04 LTS. I decided to first try to just release upgrade it two steps. I’d tried this in the past and failed which is why it stayed out of date for so long, but maybe the upgrade process was fixed for things to work automagically. I was a bit wrong on that, however I also found out that rebuilding from scratch is pretty easy.

3D Printing Bed Treatment

We have one material for my 3D printer that is very temperamental on the build plate. Printing using it and a clean build plate will lead to the print not sticking midway through and failing, while printing on glue stick or tape leads to it sticking so well it takes 30 minutes with a razor blade to remove it. Anything that seems to help it stick, helps it stick a bit too much, and my build plate is glass, so i can’t flex it to pop the print off. In comes the dumb idea, why not use a sticky note underneath the tape. This will let us flex the print just enough to break the seal with the build plate. It worked. So here’s how to do it.
