Getting faster 10 Gbps Ethernet on the Raspberry Pi

If you read the title of this blog post and are thinking, "10 Gbps on a Pi? You're nuts!," well, check out my video on using the ASUS XG-C100C 10G NIC on the Raspberry Pi CM4. Back? Good.

To be clear: it's impossible to route 10 gigabits of total network throughput through any Raspberry Pi on the market today.

But it is possible to connect to a 10 gigabit network at 10GBase-T speeds using a Raspberry Pi Compute Module 4 and an appropriate PCI Express 10G NIC. And on my Pi PCI Express site, I documented exactly how I got an ASUS XG-C100C working on the Raspberry Pi. All it takes is a quick recompile of the kernel, and away it goes!

The Raspberry Pi IoT Notification Bell

Harbinger of the Internet of Dings

Last year, I built the first version of what I call the "Raspberry Pi Bell Slapper." It was named that because it used a servo and a metal arm to slap the top of the bell in response to a stimuli—in this case, an email from a donation notification system for a local non-profit radio station.

This year, that same radio station had another one of their fund-raisers (a radiothon), and to celebrate, I thought I'd do the thing justice, with a better circuit (using a solenoid instead of a servo) and a 3D printed enclosure. And this is the result:

There is a Raspberry Pi Zero W with a custom solenoid control HAT on top inside the case to the left, and the solenoid right up against the bell, which is mounted on the right.

I also posted a video on YouTube exploring the project in detail: The Raspberry Pi IoT Notification Bell.

Monitor your Internet with a Raspberry Pi

Internet Service Providers are almost universally despised. They've pushed for the FCC to continue defining 25 Mbps as "high use" broadband, and on top of that they overstate the quality of service they provide. A recently-released map of broadband availability in the US paints a pretty dire picture:

Here in St. Louis—where I guess I should count my lucky stars we have 'high use' broadband available—I have only two options: I can get 'gigabit' cable Internet from Spectrum, or 75 megabit DSL from AT&T.

That's it.

And you're probably thinking, "Gigabit Internet is great, stop complaining!"

Review of Raspberry Pi's PoE+ HAT (June 2021)

The PoE+ HAT powers a Raspberry Pi 3 B+ or 4 model B over a single Ethernet cable, allowing you to skip the USB-C power adapter, assuming you have a PoE capable switch or injector.

Unfortunately, I can't recommend this new PoE+ HAT for most users, at least not in its current state.

For more background on PoE in general, and a bit more detail about the board itself and my tests, please watch my video on the PoE+ HAT—otherwise scroll past it and read on for all the testing results:

AWS S3 Glacier Deep Archive - Difficulty deleting files with accents

A few days ago, my personal AWS account's billing alert fired, and delivered me an email saying I'd already exceeded my personal comfort threshold—in the second week of the month!

Knowing that I had just rearranged my entire backup plan because I wanted to change the structure of my archives both locally and in my S3 Glacier Deep Archive mirror on AWS, I suspected something didn't get moved or deleted within my backup S3 bucket.

And I was right.

But I wanted to write this up for two reasons:
