Tertiary Parts of an NFC Music Player

The devil is always in the details with large systems like this. I wanted my multi room audio system to feel like a polished product, a professional setup. For that I need to make sure I covered ALL the details, since it’s all the small things that can add up to big issues. Here is a smattering of the details I’ve been working on for my multi room audio system.

Finishing Old Projects 2 – Bioshock Pistol

This second project is the pistol from Bioshock, it is primarily 3d printed with some extra materials thrown in. I picked up a toy pistol, cleaned out some old cans, and printed off some of the pieces to mod it into the fully upgraded pistol from the game. Except the problem is I never got further than painting a few of the printed parts, no assembly was ever started, so now it’s time to fix that.

Assigning Unique IDs to Template Helpers

I ran into an odd issue while trying to use a template sensor, home assistant gave me an error that I needed to have a unique id in order to use the sensor. Luckily, this is surprisingly simple to add.

It really is just a one line addition to the yaml for the sensor to add a unique ID. You can also use an online generator to create the ID to make sure conflicts are avoided.

- sensor:
    unique_id: asdf
    name: a_to_b

JetKVM

After the BliKVM PCIE failed to work at all, I decided to try one of the new little IP KVM units out there. I went with the JetKVM because its main distributor isn’t AliExpress (after the BliKVM didn’t work at all), and seemed to be pretty high quality on top of that. I wanted to set it up to have the ability to remote power on my NVR as well as to monitor it.

Finishing Old Projects 1 – Adafruit Gas Mask

I have a number of old projects I started years ago and never got around to finishing. Some of these have electronics in the plans, others are just 3d prints. Many of them I purchased parts for, or printed parts of them, but I just never managed to finish them. So I plan on getting them done, cutting a few corners to do so, but it’s better than not doing them at all.

RC Mini Bot

I’ve been watching some YouTube videos featuring 3d printed battle bots recently. One of the form factors that looked neat were the antweight robots (150g), due to their small size and small price for components. I decided to design and build something similar (though no weapon) just to drive around for fun, tormenting the pets, and practicing some design work. I figure I’ll design it so a tail can be tied on with feathers for the cat to chase (the dog will chase it just because it makes noise).

NAS V2.0

My NAS has been getting old, and it’s been getting more and more noticeable over time. Considering that I built it in 2013, I’d say it’s had a good 10+ year lifespan and could use a solid upgrade. I plan on reusing a fair bit of hardware, but I also plan on moving to ZFS for my primary storage, so I’ll be getting new drives to use in a new ZFS backed array.

Unraid Disk Shown as “New Device” When Its Full of Data

While working on setting up my new hardware and bringing my unraid pool back online on it, I encountered an odd problem that made me sweat. I started my array and immediately it gave an error that the cache drive failed. This was odd since that drive was fine just before I started installing the new hardware, so what changed now. I stopped the array and looked, and it was no longer assigned as the cache drive. When I went and added it to the cache again, unraid claimed it was a “new drive” and would be wiped when the array was started.

This was very wrong, this wasn’t a new cache drive, it was the same one as before. It also has a large amount of data on it that I’d like to keep, and docker settings. So I had to figure out how to tell unraid that the drive was fine and to just use it.

I found out that this was one of the situations the “new config” option was added to the tools for. So I went to tools -> new config and applied it while saving the disk locations in the pool. I double checked them after applying the new config, went to the main page, and checked the box stating that the parity should be assumed correct. After starting the array, everything was in order again. All my containers started, data was all there, and everything was back working again.
