An Arm Mainboard for the Framework Laptop

2026-04-15 22:49:00

Using the repair-friendly Framework 13 laptop chassis, I've tested the low-end x86 option (a Ryzen AI 5 340 Mainboard), the fastest RISC-V option (DC-ROMA II), and today I'm publishing results from the only Arm Mainboard, the MetaComputing AI PC, which has a 12-core Arm SoC and up to 32 GB of soldered-on RAM.

My Framework 13 has run on x86, RISC-V, and now Arm, making it something of a 'Ship of Theseus'.

Build your own Dial-up ISP with a Raspberry Pi

Last year my aunt let me add her original Tangerine iBook G3 clamshell to my collection of old Macs1.

It came with an AirPort card—a $99 add-on Apple made that ushered in the Wi-Fi era. The iBook G3 was the first consumer laptop with built-in Wi-Fi antennas, and by far the cheapest way to get a computer onto an 802.11 wireless network.

DRAM pricing is killing the hobbyist SBC market

2026-04-02 05:00:00

Today Raspberry Pi announced more price increases for all Pis with LPDDR4 RAM, alongside a 'right-sized' 3GB RAM Pi 4 for $83.75.

The price increases bring the 16GB Pi 5 up to $299.99.

Despite today's date, this is not a joke.

I published a video going over the state of the hobbyist 'high end SBC' market (4/8/16 GB models in the current generation), which I'll embed below:

But if you'd like the tl;dr:

Bring back MiniDV with this Raspberry Pi FireWire HAT

2026-03-27 22:00:00

In my last post, I showed you to use FireWire on a Raspberry Pi with a PCI Express IEEE 1394 adapter. Now I'll show you how I'm using a new FireWire HAT and a PiSugar3 Plus battery to make a portable MRU, or 'Memory Recording Unit', to replace tape in older FireWire/i.Link/DV cameras.

The alternative is an old used MRU like Sony's HVR-MRC1, which runs around $300 on eBay1.

After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear.

I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even a modern Mac running macOS < 26, with some dongles—and transfer digital video footage between the camera and an application like Final Cut Pro.

The best laptop Apple ever made

2026-03-20 22:00:00

Today I posted a video titled The best laptop Apple ever made, and tl;dw1 it's the 11" MacBook Air.

I acknowledge in the video my pick is slightly subjective, and I also asked a number of other YouTubers which Mac laptop they consider the best (or at least most influential). If you don't want to watch the video, I'll summarize their choices here:
