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 Charnas1, the chief engineer for the Mark Rober YouTube channel.
Earlier this year, Crunchlabs launched SatGus, which is currently orbiting Earth taking 'space selfies'.

Qualcomm's buying Arduino – what it means for makers
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 AI Emperor Has No Clothes
If the size of the current AI bubble can be estimated by how many
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.

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's PCIe bus to at least tell the graphics card installed in the eGPU dock to spin up its fans and initialize.
But I wasn't able to get any output from the card (using this Linux kernel patch), and lspci did not show it. (Nor were there any logs showing errors in dmesg).

Full eGPU acceleration on the Pi 500+ with a 15-line patch
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 the regular Pi 500:
