Random Thoughts on Classical Music
2019-11-29
I just released my YouTube video Bach BWV 005 - Führ auch mein Herz und Sinn and it one again made me realize what I personally like about classical music. I am by no means an expert on this subject, and I know and respect that many people would probably disagree with me.
In this context I refer to “classical music” to anything before 1900 – I know this is a really broad and non-accurate definition and in no way scientifically correct ;) Like I said, not an expert.

Migrations
2019-11-09
Over the past few days I performed the Migration of this website from Uberspace 6 to Uberspace 7 and from Zola to Hugo. I had played around with Uberspace 7 before and I decided that the time has come to finally update. Most of the migration was actually just moving things around. It was also a wonderful opportunity to remove some old stuff I had lying around on the old webspace.

Hello World! :D
After careful consideration I switched from Zola to Hugo.
1750 Hz Pipe
2018-05-26
For many amateur radio repeaters a 1750 Hz tone call is needed to access them. As a fun project I designed a pipe that produces that tone.
I printed it on an Anet A8 3D-printer at 0.1mm layer thickness and it works fine. Depending on the pressure it generates tones between 1600 and 1850 Hz before it overblows. I was able to access multiple repeaters with this pipe, but some require a pretty steady tone.

Fixing a TCM 211682 Touch-Lamp
2018-03-16
Warning
Working on electronics that is referenced to the mains voltage is extremely dangerous. Please refer to the usual/local regulations regarding electrical safety. If in any doubt seek out the advise of a qualified person.
I consider this circuit especially dangerous to work on because it has a connection to the metalwork of the whole lamp.
I fixed a TCM 211682 Touch-Lamp. It’s a lamp that can be dimmed to three different intensities by touching the metalwork of the lamp.

OpenRCT2-OpenMusic build process
2018-02-27
For my OpenRCT2-OpenMusic project I wanted to have a build pipeline similar to how software is built. Traditionally, artists work in a DAW and do a lot of tweaking until they get the sound they want. If the score changes it’s usually not that easy to just replace it and render the audio again. Also, DAW projects are usually not easily tansferable to other systems.
For OpenRCT2-OpenMusic I wanted something different.

pipecalc Mathematics
2018-02-25
pipecalc (WebPipeCalc) is based on formulas by Dr. Ing. H. Ising, published in the German Publication “Walcker Hausmitteilung Nr. 42” from June 1971. In this post I want to summarize these formulas, because the original work is quite hard to read and for the most part doesn’t even give the units for the formulas.
Isings formulas Frequency Open pipes The first formula that Ising gives us is $$ f = \frac{c}{2 \left(\text{L} + \Delta\text{L}_\text{M} + \Delta\text{L}_\text{R}\right)} $$ which determines the frequency of the fundamental note of the pipe.

First pipe
2018-01-19
I made the first pipe with calculations from WebPipeCalc. Below you can see a few pictures of its original state. I tried to make a C5, but even with the tuning slot fully open it sounded like a B4, so I had to shorten it a little.
And this is what it sounds like:
(measured directly at the mouth of the pipe)
