How much radiation can a Pi handle in space?

Late in the cycle while researching CubeSats using Pis in space , I got in touch with Ian Charnas 1 , the chief engineer for the Mark Rober YouTube channel.

Earlier this year, Crunchlabs launched SatGus , which is currently orbiting Earth taking 'space selfies'.

The way it works:

  • You upload a photo on the Space Selfie website
  • The photo is scheduled to be taken aboard SatGus on its onboard Google Pixel phone, using a camera built by Redwire Space
  • The flight computer (FCM) receives batches of photos and associated metadata

Qualcomm's buying Arduino – what it means for makers

Arduino Uno Q SBC microcontroller board

Qualcomm just announced they're acquiring Arduino , the company that introduced a whole generation of tinkerers to microcontrollers and embedded electronics.

The Uno R3 was the first microcontroller board I owned. Over a decade ago, I blinked my first LED with an Uno; the code for that is actually still up on my GitHub .

The $45 Uno Q , a new SBC-microcontroller hybrid (pictured at the top of this post), is the latest release in the Uno lineup, replacing the $27 Uno


The AI Emperor Has No Clothes

AI influencer deal offer

If the size of the current AI bubble can be estimated by how many

  • AI job offers
  • AI product review offers
  • AI service paid sponsorship offers
  • AI creator representation offers

I receive per day... then I'd say we're nearing the pop.

There is no way the trillions of dollars of valuation placed on AI companies can be backed by any amount of future profit.

There are good use cases for machine learning, AI, etc. But sadly, the best ones are masked by the hype-train AI


Not all OCuLink eGPU docks are created equal

I recently tried using the Minisforum DEG1 GPU Dock with a Raspberry Pi 500+, using an M.2 to OCuLink adapter, and this chenyang SFF-8611 Cable .

After figuring out there's a power button on the DEG1 (which needs to be turned on), and after fiddling around with the switches on the PCB (hidden under the large metal plate on the bottom; TGX to OFF was the most important setting), I was able to get the Raspberry Pi

Instead of a traditional review of a new Pi product, I thought I'd split things up on my blog, and write two separate posts; this one about hacking in an eGPU on the Pi 500+, for a massive uplift in gaming performance and local LLMs, and a separate post about the Pi 500+'s new mechanical keyboard .

The Raspberry Pi 500+ was announced today, sells for $200, and adds on the following over what was present in

You can finally manage Macs with FileVault remotely in Tahoe

For years, I've had a couple Macs running at home and at my studio, which I use to remotely manage my video projects or some coding project.

It's nice to have a workstation set up that you can access anywhere via Screen Sharing to check on progress, jot down a note, etc.—and not be tied to a web app or some cloud service.

I run a Wireguard VPN at home and at my studio, so I can remotely log into any of my infrastructure


I regret building this $3000 Pi AI cluster

Raspberry Pi AI 10 node compute blade server

I ordered a set of 10 Compute Blades in April 2023 (two years ago), and they just arrived a few weeks ago. In that time Raspberry Pi upgraded the CM4 to a CM5, so I ordered a set of 10 16GB CM5 Lite modules for my blade cluster. That should give me 160 GB of total RAM to play with.

This was the biggest Pi cluster I've built, and it set me back around $3,0


Save video still frames from QuickTime Player with a shortcut

Almost 15 years ago, I wrote Grab a Single Frame from a Video in QuickTime X . And for many years since, I slightly modified that workflow. Instead of using Preview, I would use pngpaste , and paste the copied frame from QuickTime player into a file.

For example:

  1. Open a video in QuickTime and scrub to the frame you would like to save as an image.
  2. Press Command-C
  3. Switch to Terminal
  4. Run pngpaste image-name-here.jpg
  5. Profit!

However, there are two problems with

Digging deeper into YouTube's view count discrepancy

For a great many tech YouTube channels, views have been markedly down from desktop ("computer") users since August 10th (or so).

This month-long event has kicked up some dust—enough that two British YouTubers, Spiffing Brit and Josh Strife Hayes are having a very British argument 1 over who's right about the root cause.

Spiffing Brit argued it's a mix of YouTube's seasonality (it's back to school season) and channels falling off,
