Hi! I’m David. I also go by dave/davidk.
I work on the things that make up cloud infrastructure, mostly tailored to all things Linux.
This page is a collection of pointers to my side projects, time permitting: mostly consisting of software, electronics and 3D printables.
GitHub has a bunch of things i’ve written over the years.
I have an interest in small embedded systems, so sometimes distributions and kernels that i’ve built end up there.
For circuits and PCBs, OSHPark’s shared projects has a bunch of things i’ve gotten fabricated.
If toys interest you:
Another explanation is available via @rrmutt, who had a set of boards made (and tried it out):
For slightly more practical things:
The (now very out of date) stratum 1 NTP server has gotten attention over the years (and a lot of really great feedback, too):
It’s very out of date now, but there are several places that have updated builds. If you’re interested, satsignal.eu has tons of up-to-date information in this area.
And the somewhat obscure, but occasionally useful:
- Avrrrinator v3, a programming adapter for the Bus Pirate v3 that lets you select between two attached AVR boards for programming
- Segger SWD/JTAG Breakout Board: A breakout board for the Segger J-Link to the smaller SWD 1.27mm pitch headers
I’ve also dedicated a significant amount of time to producing enclosures for electronics, and other practical items.
Sources usually appear under the Collector3 org since they don’t need full documentation.
Some of the designs have writeups here:
Printables out there in the world
Here are a few that i’ve spotted, or have spotted features for (i’m always really happy to see these, feedback is rare):
Featured, YouMagine: A modular Raspberry Pi Camera Enclosure
Featured, YouMagine: Miniature Camera Enclosure
I’m on twitter as @keyglitch (for completed things) and similarly on @firstname.lastname@example.org for in-progress work.
If you need help, please ask and i’ll do my best to help.
