About things, that are of interest to me (in English and in German).


Recent Updates to Link Collection

See my link collection pages here. The individual changes are listed below.

Nascom continued 1

Here is a link to the Nascom schematics again as a reference.

At this point, when I build the boards below, my Nascom still existed as the original board. The board was roughly the size of a DIN A4 sheet of paper. With the help of the Z80 buffer and the parallel bus cards shown here, I was able to move the Nascom piece by piece to a card system consisting of a couple of 100x160mm cards.

Serial connection for Odroid

Recently, I purchased an Odroid C2 board with the intention to replace my current Odroid C1 board. The C1 is currently in use as my constantly running micro home server. The C2 builds upon the ARM A53 architecture, which is 64bit as compared to the 32bit A7 architecture of the Odroid C1. The C2 has 2Gb of RAM and the CPU runs at 2GHz.

Digitising Slides

Some time ago my wife came home from a visit with her parents with a box containing all the slides her dad had shot during the late 50s, the 60s and the 70s until he switched from slide to negative film.

I’m going to present my solution to digitise a sizeable amount of slides in a reasonable amount of time in this post.

Importing and Organizing Photos with exiftool

Until recently I’ve been using Digikam to organise and rename my digital photos, sorting them into directories and so on. With my recent move to the KDE5/QT5 desktop environment, the stable 4.x Digikam needed uninstalling due to some dependency collision on my Gentoo Linux installation.

But in the meantime, I’ve found, that ExifTool is actually quite superior for importing and organising for photo files from the camera. Here is how I do it.
