Photos

9V Battery

A little experiment with focus stacking. I used my 16mm macro extension tube and set focus bracketing on my camera to take 8 photos with different focus. Then I merged them together in HeliconFocus to get the entire battery in focus.

I tried using Photoshop to merge them first, but I think it needs more images with smaller differences in focus. HeliconFocus had much better results with this set of images.

ArgonOne NVMe Expansion

This weekend I upgraded the Raspberry Pi that hosts my Mastodon instance and Home Assistant (among other services) with an NVMe drive.Β Β Previously it was using an old mechanical USB hard drive, so the performance increase with the NVMe is huge!Β Β 

It runs a bit hotter than with the microSD card + external HDD, but it’s nice to have everything in one case without worrying about SD card wear anymore.

I also finally got around to upgrading from Ubuntu 20.04 to Ubuntu 22.04, just in time for the next LTS release later this year.
