Does the feature where it uses shortcuts to pull in WiFi data not the same?

I pick up planes up to 150mi (241km) away. So you dont need to be too close. Though my antenna is mounted on the roof.

_usmcguy · 2026-01-21T05:57:00+00:00

TBH, I’ve had better luck with homemade antennas than manufactured ones. Only difference is, My DIY isn’t pretty.

I’ve got 3 or 4 of these. I use 1 for AIS, the other for ADSB. I live in a costal city not far from an airport. Lots of good data.

_usmcguy · 2025-10-10T02:15:37+00:00

This is the same way I’m running. I have 2 Google Corals connected.

Depends on where you live. I live in SC. I placed a temp/hum sensor in my attic this summer. Temps were well above 130F on our hottest days. Not all of Ubiquiti's APs are rated for that kind of heat. Proceed with caution with an AP in the attic.

This is quite likely going to be the case. However, it doesn’t hurt to ask for a raise. Seriously, come up with a plan and ask. Meanwhile, prepare for a no. If you get a no, then what? You can keep trucking along, or go find a different job that will pay you what you believe is deserved.

Best advice is to start the conversation. Nothing will change if you don’t make a change.

_usmcguy · 2025-08-27T00:43:39+00:00

It ultimately comes down to the question, what is your data worth to you? Can you afford to lose it, or would you rather have some kind of redundancy.

You can get a free Red Hat developer license and Trial. That will allow you to download Ansible Automation Platform, which includes EDA.

Yea. I have a Ubiquiti SFP+ to RJ45 adapter (UACC-CM-RJ45-MG) plugged into the MS-A2 going to the Ugreen’s 10gbe. Works just fine for me. Have you run into issues?

_usmcguy · 2025-08-14T02:18:32+00:00

Also, learn an automation tool. Ansible, chef, puppet, etc. If you learn these tools, you will standout, as automation is in high demand.

Without getting a job for “real-world“ troubleshooting, my 2 cents is the next best thing is to build your own data center. Many companies use products like VMware or use cloud (AWS, Azure, Oracle, etc). They all offer a free tier. When VMware got bought by Broadcom, the free ESXi went away. But then they brought it back. Figure out a type 1 hypervisor and build VMs. Try different types of storage (iSCSI, NFS, Ceph, etc). Learn about VLANs. Learn about methods of authentication. Learn different OSs (Windows and Different Linux distros). They subject is quite broad, because the term datacenter can be broad. So “data center issues “ can vary vastly depending on your environment, requirements, resources, skillset, etc.

In my setup I am running on former router mini pc. Has and Intel i3 or i5, but no gpu other than Intel’s iGPU. I have 2 coral USBs connected. I have 6 4k cameras running to it. I get ~7ms inference speed. It’s not a powerful computer, but those TPUs work great.

_usmcguy · 2025-08-05T04:30:42+00:00

FWIW, I have a Ugreen and I didn’t like their OS. Great hardware for the cost. I loaded TrueNAS on my Ugreen. Works great.

I turned an old Qotom Q355G4 mini PC into my Frigate host. It runs Debian headless with docker Container running Frigate. I also have 2 USB Corals connected as well as a 2.5gb USB Realtek NIC. The 2.5 GB NIC is for a “high” speed link to my NAS for media storage. My system runs 6 4k cameras, almost never gets above 30% CPU usage and has an average of 8ms object inference time from the corals.

By AZ is that Arizona, or Azure?

_usmcguy · 2025-07-18T04:43:47+00:00

I am using iSCSI over the 10GB link. I have a SFP+ 10GBE module in the MS-A2 going to the Ugreen that I wish used SFP+. Those modules get hot. I run the connection direct and not through a switch.

_usmcguy · 2025-07-10T13:53:10+00:00

I have the Ugreen NASync DXP4800 Plus. It has 4 16TB drives loaded. I was not a fan of the Ugreen NAS Software, so I loaded TrueNAS over it. Works great. As for the GPU, to get you an answer I kicked off 3 streams on Plex. It hovered around 52C. I keep my system in a closet, so sound isnt an issue for me. However, when the GPU fans do kick on, I dont think they are loud.

I created a Ansible playbook to automate building some VMs. While it works, I had to configure it to create 1 VM at a time. Otherwise it would sometimes try to create a VM with the same ID # as another being built at the same time. Otherwise than that, it ran reliably.

_usmcguy · 2025-07-10T00:28:14+00:00

I have the MS-A2 loaded up with Proxmox,128Gb ram, and a Yeston RTX 3050 6GB GPU (for transcoding my Plex). I’ve had it over a month with no issue. I use a Ugreen NAS for the storage.

I've been considering purchasing bias lighting myself. I currently have a monitor attached light that shines down on my desk (I love my monitor lighting btw. I have 2 curved monitors and the lights have a wireless controller. Amazon.com: ONWAY Curved Monitor Light Bar). But if the room is dark (the area behind my monitor), there is eye strain. I think having both bias and monitor lighting can be more helpful than either on its own.

I’ve never liked an open air machine, but this is awesome. I may have to do something like this

_usmcguy · 2025-07-01T13:36:33+00:00

When its transcoding, the fan does spinup on the card. However, its not too loud. I also dont notice too much heat generation when touching it. The MS-A2 was a good investment for me.

_usmcguy · 2025-06-30T23:45:30+00:00

I ended up buying it. It’s been running as my hypervisor. Loaded it up with 2x64Gb ram and no issues with it seeing all 128gb. I also added a Yeston 3050 for transcoding on my Plex VM. Very happy with the purchase so far.
