The Raspberry Pi Pico W brings WiFi for $6

Today, Raspberry Pi announced the Pico W, a new $6 version of the Pico that includes WiFi.

No word yet on Bluetooth. The WiFi chip in the Pico W (Infineon CYW43439) supports it, but right now the RP2040 firmware lacks Bluetooth support.

The Pico W being available for just $6 is huge, because one of the chief complaints about the original Pico (powered by Raspberry Pi's own RP2040) was its lack of wireless support—a feature present on similarly-priced boards based on the ESP32 and ESP8266.

Answering Questions about the PetaPi

A few weeks ago, I posted a video about the Petabyte Pi Project—an experiment to see if a single Raspberry Pi Compute Module 4 could directly address sixty 20TB hard drives, totaling 1.2 Petabytes.

And in that video, it did, but with a caveat: RAID was unstable. For some reason, after writing 2 or 3 GB of data at a time, one of the HBAs I was using would flake out and reset itself, due to PCI Express bus errors.

Industrial Raspberry Pi computers (one is explosion-proof)

In today's video, I highlighted industrial Raspberry Pi computers. Specifically, the Lincoln-Binns CM4-Box Pro, the Onlogic Factor 201, and fieldcloud's Milü-X Industrial IoT Gateway.

And I asked Lincoln-Binns, Onlogic, and fieldcloud what makes an 'Industrial' Pi any different than a Pi and an enclosure like you could buy from a normal Pi retailer.

Last week this Tweet crossed my timeline:

If you look closely, that's a "Raspberry Pi Compute Module 3E"—which is so far not listed on Raspberry Pi's website.

Benchmarking DNS on my Mac with Pi-Hole

After watching Level1Techs' THE FORBIDDEN ROUTER II - DIAL-UP BY DAWN video, I wanted to do some DNS benchmarking on my local network.

Since I run Pi-hole locally, and rely on it for local DNS resolution, I wanted to have a baseline so I could compare performance over time.

In the video, Wendell mentioned the use of Gibson's Windows-only DNS Benchmark tool. But that's Windows-only. Or maybe Linux under WINE, but definitely not a native / open source tool that's easily used across different platforms.

I looked around and settled on bulldohzer—for now, at least—as it's easy to install anywhere Node.js runs. I have Node.js installed via Homebrew on my Mac, so I just ran:

npm install --location=global bulldohzer

Then I could run a benchmark against Google and my own local DNS resolver (Pi-Hole):
