MirkoPC - a full-featured Raspberry Pi desktop computer

The MirkoPC is so far the closest thing to a full-fledged Raspberry Pi desktop computer:

MirkoPC with Raspberry Pi Compute Module 4

Based on the Compute Module 4, it has a full-size M.2 M-key slot, allowing the Pi to boot from reliable and fast NVMe SSD storage, a built-in headphone amp and line out, 4 USB 2.0 ports, gigabit Ethernet, two HDMI ports, and a number of other neat little features.


I also have a video review of this board here:

Setting up Starlink, SpaceX's Satellite Internet

Starlink Dishy and box from SpaceX

In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above.

I was a little too excited about getting Starlink, though, because I realized after I started looking for mounting locations that Starlink needed a 100° view of the northern sky, and my house is literally surrounded by 70-80 ft trees.

So I thought, why not let a cousin who lives out in a rural area try it out while I figure out what to do about mounting 'Dishy' (a common nickname for the Starlink satellite dish) on my own house?

After all, my cousin Annie, who lives in Jonesburg, MO, currently pays for the maximum available DSL plan to her farm (Haarmann Farms), and gets a measly 5 Mbps down, and 0.46 Mbps up—on a good day:

Building a 2.5 Gbps 5-drive Pi NAS - Hardware Setup

A few months ago, an ASUSTOR representative emailed me with an offer I couldn't refuse. He saw my blog post and video about building the fastest Raspberry Pi NAS, and asked if I wanted to put up my best Pi-based NAS against an Asustor NAS.

We settled on the Asustor Lockerstor 4, with dual-2.5 Gbps networking, 4 GB of RAM, and a quad-core Intel CPU. To make things even, he convinced Seagate to send four 8TB IronWolf NAS drives. I don't fancy he thought it would be a good show if I kept on using my four used WD GreenPower drives from 2010!

I posted a video of the hardware build process for both NASes on my YouTube channel:

Setting up a Pi for remote Internet connection monitoring

So... recently I acquired a Starlink 'Dishy', and I'm going to be installing it at a rural location near where I live, but since it's a bit of a drive to get to it, I wanted to set up a Raspberry Pi to monitor the Starlink connection quality over time.

I know the Starlink app has its own monitoring, but I like to have my own fancy independent monitoring in place too.

The wrinkle with a Starlink-based Internet connection, though, is that SpaceX is using Carrier-Grade NAT (CGNAT) on their network, so there won't be any kind of IPv4 address I could reach the Pi at, nor does SpaceX yet have IPv6 set up in their network.

So to make remote access possible, I would have to find a way to have the Pi reach out to one of my servers with a persistent connection, then I could 'tunnel' through that server from other locations to reach the Pi.

The Raspberry Pi can boot off NVMe SSDs now

When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board.

The initial response in October 2020 was "we'll see". Luckily, after more people started asking about it, beta support was added for direct NVMe boot just a couple weeks ago.
