Getting Started with Meshtastic

After seeing the Meshtastic booth at Open Sauce, my Dad and I thought it would be fun to learn more about the low power radio tech by getting our own radios and experimenting.

Then, we were contacted by Simon from Muzi Works, and he offered to send a few units of R1 and H1, his company's pre-built Meshtastic nodes.

What's a node, and what is Meshtastic? Excellent question.

What is Meshtastic?

Simply put—and copied shamelessly from the official website:

An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices

Meshtastic nodes are often tiny gumstick-size PCBs with a LoRa radio module, a couple buttons, a tiny OLED display, and a USB port.

The state of Docker on popular RISC-V platforms

The state of Docker on popular RISC-V platforms

I've been testing a Milk-V Jupiter this week, and have tested a number of other RISC-V development boards over the past two years.

As with any new CPU architecture, software support and ease of adoption are extremely important if you want to reach a wider audience. I wouldn't expect every developer and SBC hobbyist to be able to compile the Linux kernel, and the need to compile much of anything these days is getting rare. So having any instance where one has to know how to tweak a Makefile or pass in different flags to a compiler is a bit of a turn-off for platform adoption.

So one thing I've followed closely is how easy it is for me to get my own software running on RISC-V boards. It's one thing to run some vendor-provided demos. It's another entirely to take my real-world applications and infrastructure apps, and get them to work without hassle.

And to that end, Docker and Ansible, two tools I use extensively for dev/ops work, both run stably—though with plenty of caveats since RISC-V is still so new.

Where is Qualcomm's Snapdragon X Elite Dev Kit?

Where is Qualcomm's Snapdragon X Elite Dev Kit?

I signed up to buy a Qualcomm Snapdragon X Dev Kit the second I found out about it. It's supposed to be the Mac mini killer for Windows.

They even promoted it with this amazing-looking transparent shell, and I and hundreds of other devs were ready to pony up the $899 Qualcomm was asking.

Their pre-order form said it would be out June 18. Almost exactly one month later, I got an email saying it was available. Great!

So I went to the purchase page on Arrow... and it showed as out of stock. That was about 15 minutes after receiving the email.

There were three possibilities:
