M.2 on a Raspberry Pi – The Tofu CM4 Carrier Board
Ever since the Pi 2 model B went to a 4-core processor, disk IO has often been the primary bottleneck for my Pi projects. You can use microSD cards, which aren't horrible, but... well, nevermind, they're pretty bad as a primary disk. Or you can plug in a USB 3.0 SSD and get decent speed, but you end up with a cabling…

Thoughts on Daylight Computer
on the Amtrak from Denver to Sacramento When I get to write or read on a screen that’s reflecting the sun back at me instead of needing to be shielded from it, I get a dose of this feeling that this is what all computing could feel like. I want so much more of this in my life. This is a piece of hardware that makes me…

LTO Tape data storage for Linux nerds
Tape storage is surprisingly not dead! If you are here then you may be considering using LTO tape as part of your backup or your long term archiving strategy. I’m here to mostly talk you out of it, or at best make sure that you are aware of what you are walking into.

Crowdfunding the Novena Open Laptop
We’re launching a crowdfunding campaign around our Novena open hardware computing platform. Originally, this started as a hobby project to build a computer just for me and xobs – something that we would use every day, easy to extend and to mod, our very own Swiss Army knife. I’ve posted here a couple of times about…

That UPS you bought for your home server may not be as useful as you think
Some years ago I decided to install a server at home for use as a NAS (network-attached storage) in my home network, and for an Internet-facing server. I live in a place where blackouts are very in…

Miniature 3456 LED Cube
For some reason, I’m intrigued by LEDs. Indeed, they can be found in pretty much all of my projects. I was recently inspired by one of Greg Davill’s projects, a miniature LED cube boasting a total of 3456 LEDs . After pondering about it for a while, I decided I’d attempt building one myself. This post describes the…
