+## Die Zeiten ändern sich {id=times-are-changing}
+
+Niemand weiß so recht hin oder her - es ist eine nie dagewesene Situation. Und doch muss man irgendwie damit umgehen. Ein Virus geht um, und alle Welt verschanzt sich plötzlich hinter ihren Fenstern und Haustüren. Ganz klar: es geht um die Corona-Pandemie, und den damit einhergehenden Lockdown. Auch Schulen waren in dieser Zeit lange geschlossen, statt Präsenzunterricht vor Ort gab es nun Homeschooling. Für einige war das Internet dabei noch immer Neuland, für andere schuf diese neue Lebensrealität ungeahnte (auch zeitliche) Möglichkeiten. Darunter auch ich - damals in der siebten Klasse eines bayerischen Gymnasiums.
+
+
+## Das Projekt {id=the-project}
+
+Im Unterrichtsfach NuT, das Physik und Informatik kombiniert, gab es einen umfangreichen Arbeitsauftrag: nachdem man sich mit Graphen und dem Internet als gewaltiges Netzwerk, darstellbar als Graphen beschäftigt hatte, sollte es nun in die Praxis gehen. Das Ziel: eine Website mit HTML (und CSS) bauen, um die Funktionsweise des World Wide Web (WWW) als ganzes besser zu verstehen - der Name lautete recht vielsagend „**Projekt WWW**”. 
+
+„Klasse! - endlich mal von schulischer Seite das machen dürfen, was mich sowieso total interessiert” - so oder so ähnlich habe ich damals gedacht. Jedenfalls machte ich mich mit einem Klassenkameraden sofort an die Arbeit (wie sofortig genau, das weiß ich nicht mehr), wir machten uns Gedanken über den Aufbau, wir schrieben Gedichte, sammelten Bilder und suchten Definitionen heraus. Für den technischen Kram war dabei vor allem ich verantwortlich, er mehr für den Inhalt und Kontrolle.
+
+
+## Warum das ganze? {id=why-all-this}
+
+Wer bis hier gelesen hat, stellt sich vielleicht diese Frage. Nun ja - erstens sind gerade Herbstferien und damit Zeit, um zumindest ein wenig auf andere Gedanken zu kommen (beispielsweise endlich wieder ein wenig für eine mögliche Amateurfunkprüfung lernen) und in Erinnerungen zu schwelgen. So fand ich das Projekt in den Untiefen des Dateisystems meines Rechners - und war aufs neue ganz erstaunt darüber, was wir damals geleistet haben und dachte mir, das könnte ich doch auf meinem etwas persönlicheren Blog hochladen. 
+
+Auch für den Leser könnte es interessant und bestimmt ein bisschen nostalgisch sein, über das nachzudenken, was man früher schon alles geschafft hat. Oft ist man selbst erstaunt über das, was man dabei herausfindet.
+
+
+## Das Ergebnis {id=the-result}
+
+In brevitas veritas (oder so ähnlich), hat mal einer gesagt: hier also die Ergebnisse zum interaktiven Durchklicken - schließlich ist es ja eine Website - als iFrame! Und wer es lieber etwas größer mag, kann es sich [hier](/specials/2025/11/03_-_nostalgic_memories/) ganz ohne iFrame ansehen.
+

+
+Der Graph, der die Verbindungen der Seiten untereinander darstellt, lässt sich [hier](/specials/2025/11/03_-_nostalgic_memories/connections-graph.pdf) abrufen.
+
+Nach damaligen Webstandards hat sie funktioniert, heute scheinbar nicht mehr - so erkläre ich mich einige Artefakte und seltsame Darstellungen. Jedenfalls sind hier einige witzige Fakten - manchmal auch erfunden - auszumachen, natürliche süße Katzenbilder wie im Internet eben so üblich und auch etwas technischere Angaben dürfen nicht fehlen.
+
+Ach ja, fast hätte ich es vergessen - es handelte sich doch um ein Schulprojekt! Was ich darauf für eine Note bekam, weiß ich bis heute nicht. Auch nicht, ob es überhaupt jemals bewertet wurde.

+title = 'Between Homeschooling And Web Design - nostalgic memories of seventh grade'

+
+## Times are changing {id=times-are-changing}
+
+No one really knows one way or the other—it's an unprecedented situation. And yet, somehow, we have to deal with it. A virus is spreading, and suddenly the whole world is barricading itself behind windows and front doors. Clearly, we are talking about the coronavirus pandemic and the accompanying lockdown. Schools were also closed for a long time during this period, with homeschooling replacing face-to-face teaching. For some, the internet was still uncharted territory, while for others, this new reality created unexpected opportunities (including in terms of time). I was one of them - at the time in seventh grade at a Bavarian high school.
+
+
+## The Project {id=the-project}
+
+In the subject NuT, which combines physics and computer science, there was an extensive assignment: after studying graphs and the Internet as a huge network that can be represented as graphs, it was time to put theory into practice. The goal: to build a website using HTML (and CSS) in order to better understand how the World Wide Web (WWW) works as a whole—the name was quite telling: “**Project WWW**.” 
+
+“Great! Finally, I get to do something at school that I'm really interested in anyway,” or something like that, I thought at the time. In any case, I immediately got to work with a classmate (I don't remember exactly how immediately), we thought about the structure, wrote poems, collected pictures, and looked up definitions. I was mainly responsible for the technical stuff, while he was more responsible for the content and supervision.
+
+
+## Why all this? {id=why-all-this}
+
+Anyone who has read this far may be asking themselves this question. Well, first of all, it's autumn holidays, which means it's time to take my mind off things for a bit (for example, finally studying a little for a potential amateur radio exam) and reminisce. That's how I found the project in the depths of my computer's file system - and was once again amazed at what we had achieved back then and thought to myself that I could upload it to my more personal blog. 
+
+It might also be interesting and certainly a bit nostalgic for readers to think about everything they've accomplished in the past. Often, you'll be amazed at what you discover.
+
+
+## The result {id=the-result}
+
+In brevitas veritas (or something like that), someone once said: so here are the results for interactively clicking through — because it's a website — as an iFrame! And if you prefer something a little bigger, you can view it [here](/specials/2025/11/03_-_nostalgic_memories/) without any iFrames.
+
+{{< iframe src="/specials/2025/11/03_-_nostalgic_memories/" style="aspect-ratio: 16/20" >}}
+
+The graph showing the connections between the pages can be accessed [here](/specials/2025/11/03_-_nostalgic_memories/connections-graph.pdf).
+
+It worked according to the web standards of the time, but apparently no longer does today - that's how I explain some of the artifacts and strange displays to me. In any case, there are some funny facts here — some of them made up — as well as the usual cute cat pictures found on the internet and some more technical information.
+
+Oh yes, I almost forgot — it was a school project! To this day, I still don't know what grade I got for it. Nor do I know if it was ever graded at all.

+&lt;p>Niemand weiß so recht hin oder her - es ist eine nie dagewesene Situation. Und doch muss man irgendwie damit umgehen. Ein Virus geht um, und alle Welt verschanzt sich plötzlich hinter ihren Fenstern und Haustüren. Ganz klar: es geht um die Corona-Pandemie, und den damit einhergehenden Lockdown. Auch Schulen waren in dieser Zeit lange geschlossen, statt Präsenzunterricht vor Ort gab es nun Homeschooling. Für einige war das Internet dabei noch immer Neuland, für andere schuf diese neue Lebensrealität ungeahnte (auch zeitliche) Möglichkeiten. Darunter auch ich - damals in der siebten Klasse eines bayerischen Gymnasiums.&lt;/p></description></item><item><title>UV-Belichter (LED) aus Marke Eigenbau</title><link>https://blog.privacynerd.de/de/posts/2025/04/diy-uv-pcb-exposure-unit/</link><pubDate>Mon, 14 Apr 2025 08:11:20 +0200</pubDate><guid>https://blog.privacynerd.de/de/posts/2025/04/diy-uv-pcb-exposure-unit/</guid><description>&lt;p>Ist man eine gewisse Zeit lang in der (Elektronik-)DIY-Szene unterwegs, kommt man irgendwann auch um Platinen (gedruckte Leiterplatten/PCBs) nicht herum.

 &lt;p>Ich habe lange überlegt, wie ich diesen Post schreibe. Was muss erzählt werden, was ist unwichtig? Vieles muss wegen der Übersichtlichkeit weggelassen werden, und an so manches erinnere ich mich vielleicht schon gar nicht mehr. Jedenfalls möchte ich mit diesem Artikel meine Intention erklären, wie ich dazu kam, diesen Blog zu starten. Doch um das zu erklären, muss man die Ursprünge verstehen.&lt;/p>
 &lt;h2 id="beginnings">Wie alles anfing&lt;/h2>
 &lt;p>Alles begann damit, dass ich als Schüler der 5. oder 6. Klasse (ich weiß es nicht mehr so genau!) anfing, auf einem Laptop für die Schule ein Batch-Skript zu schreiben. Ja, so war es, ich gebe es zu - auch wenn ich nicht weiß, wer oder was mich dazu trieb. Eine grobe Vorstellung habe ich aber: Ich glaube, es war so eine intrinsische Motivation eines Kindes, herauszufinden, wie dieser Computer da vor ihm funktioniert, die mich dazu trieb.&lt;/p></description></item><item><title>Über</title><link>https://blog.privacynerd.de/de/about/</link><pubDate>Sun, 13 Apr 2025 13:02:20 +0200</pubDate><guid>https://blog.privacynerd.de/de/about/</guid><description>&lt;h2 id="intention">Worum es hier gehen soll&lt;/h2>

Vorteile gegenüber dem manuellen Löten von Schaltungen auf Loch- bzw. Streifenrasterplatinen sind vor allem die einfachere Replizierbarkeit (einmal designed kann man eine Schaltung theoretisch beliebig oft herstellen) und die Möglichkeit, Platz effizienter zu nutzen (eine Platine ist fast immer kleiner als eine gelötete Lochrasterplatine mit der selben Schaltung). Letzendlich wirken Geräte mit Platinen aber auch schlicht professioneller. Sicherlich gibt es noch mehr Vorteile (und natürlich auch Nachteile!), auf deren Auflistung ich hier allerdings aus Gründen der Einfachheit verzichte.</p><p>Heutzutage kann man (selbst) kreierte Leiterplattendesigns sehr leicht herstellen lassen, bei einschlägigen Angeboten aus China zahlt man für eine einfache Platine mit 2 Seiten nicht mehr als 5€. Im Preis allerdings nicht mit inbegriffen sind die Versandkosten und die Wartezeit, in der man auf seine Platinen warten muss. Wenn man nicht vorhat, mehrere verschiedene Designs im Jahr anzufertigen, oder nur einmalig eine spezielle Platine braucht, ist mit solchen Angeboten gut bedient. Braucht man allerdings des öfteren Spezialanfertigungen, kann es (auch bei den chinesischen Angeboten) schnell lukrativ erscheinen, sich die Fertigung ins Haus zu holen. Letztlich macht es auch einfach Spaß und gibt einem zumindest das Gefühl von ein wenig Unabhängigkeit, seine Platinen selbst herzustellen!</p><p>Nachdem ich also schon länger von eigens hergestellten Platinen träumte, bin ich nun einen Schritt weiter in die Umsetzung gegangen. Es gibt verschiedene Möglichkeiten, Leiterplatten selbst herzustellen. Die günstigste Methode ist hierbei vermutlich das Belichten eines Platinenrohlings mit photopositiver Beschichtung, und das anschließende Entwickeln und schließlich Ätzen der belichteten Stellen. Das Gerät zum Ätzen selbst zu bauen erschien mir zu heikel, hier entschied ich mich vorerst für ein gebrauchtes <a href=https://gie-tec.de/produkt/aetzgeraete-fuer-platinen/>Ätzgerät 1 von pro-ma</a>, was mit 50€ sehr günstig war. Was man aber sicher selbst bauen kann, ist der <strong>UV-Belichter</stLine truncated

Das Ziel: eine Website mit HTML (und CSS) bauen, um die Funktionsweise des World Wide Web (WWW) als ganzes besser zu verstehen - der Name lautete recht vielsagend „<strong>Projekt WWW</strong>”.</p><p>„Klasse! - endlich mal von schulischer Seite das machen dürfen, was mich sowieso total interessiert” - so oder so ähnlich habe ich damals gedacht. Jedenfalls machte ich mich mit einem Klassenkameraden sofort an die Arbeit (wie sofortig genau, das weiß ich nicht mehr), wir machten uns Gedanken über den Aufbau, wir schrieben Gedichte, sammelten Bilder und suchten Definitionen heraus.

Nun ja - erstens sind gerade Herbstferien und damit Zeit, um zumindest ein wenig auf andere Gedanken zu kommen (beispielsweise endlich wieder ein wenig für eine mögliche Amateurfunkprüfung lernen) und in Erinnerungen zu schwelgen.

+&lt;p>Niemand weiß so recht hin oder her - es ist eine nie dagewesene Situation. Und doch muss man irgendwie damit umgehen. Ein Virus geht um, und alle Welt verschanzt sich plötzlich hinter ihren Fenstern und Haustüren. Ganz klar: es geht um die Corona-Pandemie, und den damit einhergehenden Lockdown. Auch Schulen waren in dieser Zeit lange geschlossen, statt Präsenzunterricht vor Ort gab es nun Homeschooling. Für einige war das Internet dabei noch immer Neuland, für andere schuf diese neue Lebensrealität ungeahnte (auch zeitliche) Möglichkeiten. Darunter auch ich - damals in der siebten Klasse eines bayerischen Gymnasiums.&lt;/p></description></item><item><title>UV-Belichter (LED) aus Marke Eigenbau</title><link>https://blog.privacynerd.de/de/posts/2025/04/diy-uv-pcb-exposure-unit/</link><pubDate>Mon, 14 Apr 2025 08:11:20 +0200</pubDate><guid>https://blog.privacynerd.de/de/posts/2025/04/diy-uv-pcb-exposure-unit/</guid><description>&lt;p>Ist man eine gewisse Zeit lang in der (Elektronik-)DIY-Szene unterwegs, kommt man irgendwann auch um Platinen (gedruckte Leiterplatten/PCBs) nicht herum.

 &lt;p>Ich habe lange überlegt, wie ich diesen Post schreibe. Was muss erzählt werden, was ist unwichtig? Vieles muss wegen der Übersichtlichkeit weggelassen werden, und an so manches erinnere ich mich vielleicht schon gar nicht mehr. Jedenfalls möchte ich mit diesem Artikel meine Intention erklären, wie ich dazu kam, diesen Blog zu starten. Doch um das zu erklären, muss man die Ursprünge verstehen.&lt;/p>
 &lt;h2 id="beginnings">Wie alles anfing&lt;/h2>
 &lt;p>Alles begann damit, dass ich als Schüler der 5. oder 6. Klasse (ich weiß es nicht mehr so genau!) anfing, auf einem Laptop für die Schule ein Batch-Skript zu schreiben. Ja, so war es, ich gebe es zu - auch wenn ich nicht weiß, wer oder was mich dazu trieb. Eine grobe Vorstellung habe ich aber: Ich glaube, es war so eine intrinsische Motivation eines Kindes, herauszufinden, wie dieser Computer da vor ihm funktioniert, die mich dazu trieb.&lt;/p></description></item></channel></rss>

+&lt;p>No one really knows one way or the other—it&amp;rsquo;s an unprecedented situation. And yet, somehow, we have to deal with it. A virus is spreading, and suddenly the whole world is barricading itself behind windows and front doors. Clearly, we are talking about the coronavirus pandemic and the accompanying lockdown. Schools were also closed for a long time during this period, with homeschooling replacing face-to-face teaching. For some, the internet was still uncharted territory, while for others, this new reality created unexpected opportunities (including in terms of time). I was one of them - at the time in seventh grade at a Bavarian high school.&lt;/p></description></item><item><title>Self-built UV exposure unit (LED)</title><link>https://blog.privacynerd.de/en/posts/2025/04/diy-uv-pcb-exposure-unit/</link><pubDate>Mon, 14 Apr 2025 08:11:20 +0200</pubDate><guid>https://blog.privacynerd.de/en/posts/2025/04/diy-uv-pcb-exposure-unit/</guid><description>&lt;p>If you&amp;rsquo;ve been around the (electronics) DIY scene for a while, at some point you can&amp;rsquo;t avoid circuit boards (printed circuit boards/PCBs).

 &lt;p>I&amp;rsquo;ve been thinking about how to write this post for a long time. What needs to be told, what is unimportant? A lot has to be left out for the sake of clarity, and I might not even remember some of it. In any case, I would like to use this article to explain my intention in starting this blog.

 &lt;p>Well, my Name is Benjamin, and I’m mostly known as BlueFox. I love tinkering around with electronics, 3D printing stuff and working with wood, but I also do a bit of programming and am an avid self-hoster.&lt;/p>
 &lt;p>This is my personal blog (driven in my free time, all of this is just a hobby) about all the kinds of things I&amp;rsquo;m doing DIY-wise. This includes:&lt;/p>

The main advantages over soldering circuits by hand on perforated or strip-grid boards are that they are easier to replicate (once designed a circuit can theoretically be produced as often as you like) and that space can be used more efficiently (a board is almost always smaller than a soldered perforated grid board with the same circuit). Ultimately, devices with circuit boards also simply look more professional. There are certainly more advantages (and of course also disadvantages!), but I will not list them here for the sake of simplicity.</p><p>Nowadays, it is very easy to have (self-)created circuit board designs manufactured, with relevant offers from China you pay no more than €5 for a simple circuit board with 2 sides. However, the price does not include the shipping costs and the time you have to wait for your PCBs. If you are not planning to produce several different designs a year, or only need a special circuit board once, you are well served with such offers. However, if you often need custom-made products, it can quickly become lucrative (even with the Chinese offers) to bring the production in-house. At the end of the day, it&rsquo;s fun and at least gives you the feeling of a little independence to make your own circuit boards!</p><p>So after dreaming of making my own circuit boards for some time, I have now gone one step further in the realization. There are various ways to produce printed circuit boards yourself. The cheapest method is probably exposing a blank PCB with a photopositive coating and then developing and finally etching the exposed areas. Building the etching device myself seemed too tricky, so I decided to buy a used <a href=https://gie-tec.de/produkt/aetzgeraete-fuer-platinen/>Ätzgerät 1 from pro-ma</a>, which was very cheap at €50. But what you can certainly build yourself is the <strong>UV exposure unit</strong>. There are different approaches here, I just want to share mine here (see e.g. <a href=https://www.all4hardware4u.de/platinenherstellung/belichtung/belichtungsgeraet-mit-uv-leds/>here</a> or also <a href=http://www.fdm-ware.de/UV-Led/>here</a> for the modLine truncated
-the LEDs!) and painted it several times according to the instructions on the spray can and left it to dry overnight.</p><figure><img src=/en/posts/2025/04/diy-uv-pcb-exposure-unit/masked_for_painting.jpg alt="Picture of the box masked for painting"><figcaption><p>Box is masked, about to be painted!</p></figcaption></figure><figure><img src=/en/posts/2025/04/diy-uv-pcb-exposure-unit/painted_inside.jpg alt="Picture of the inside of the painted box"><figcaption><p>It&rsquo;s shiny!</p></figcaption></figure><h2 id=the-control-unit>The control unit<a href=#the-control-unit class=hanchor arialabel=Anchor>#</a></h2><p>Here I was faced with a choice: install a simple switch or a more complex logic with a timer function? The idea of the built-in timer seemed appealing - finally programming something hardware-related again. So I assembled a breadboard (perhaps the last one ever?!) with a Raspberry Pi Pico, relays, a connection for an LCD display and some control elements, programmed a small interface with my existing libraries and the electronics were ready! To be installed in the housing, it still needed a cover.

The second attempt was more promising, after 30 minutes of exposure the first contours could be seen after about 15 minutes of development, which actually disappeared during etching. After a few more attempts, I finally came up with the idea of working with two overlapping films instead of one, which meant that much less light came through the printed areas.

Finally, I get to do something at school that I&rsquo;m really interested in anyway,” or something like that, I thought at the time. In any case, I immediately got to work with a classmate (I don&rsquo;t remember exactly how immediately), we thought about the structure, wrote poems, collected pictures, and looked up definitions.

+&lt;p>No one really knows one way or the other—it&amp;rsquo;s an unprecedented situation. And yet, somehow, we have to deal with it. A virus is spreading, and suddenly the whole world is barricading itself behind windows and front doors. Clearly, we are talking about the coronavirus pandemic and the accompanying lockdown. Schools were also closed for a long time during this period, with homeschooling replacing face-to-face teaching. For some, the internet was still uncharted territory, while for others, this new reality created unexpected opportunities (including in terms of time). I was one of them - at the time in seventh grade at a Bavarian high school.&lt;/p></description></item><item><title>Self-built UV exposure unit (LED)</title><link>https://blog.privacynerd.de/en/posts/2025/04/diy-uv-pcb-exposure-unit/</link><pubDate>Mon, 14 Apr 2025 08:11:20 +0200</pubDate><guid>https://blog.privacynerd.de/en/posts/2025/04/diy-uv-pcb-exposure-unit/</guid><description>&lt;p>If you&amp;rsquo;ve been around the (electronics) DIY scene for a while, at some point you can&amp;rsquo;t avoid circuit boards (printed circuit boards/PCBs).

 &lt;p>I&amp;rsquo;ve been thinking about how to write this post for a long time. What needs to be told, what is unimportant? A lot has to be left out for the sake of clarity, and I might not even remember some of it. In any case, I would like to use this article to explain my intention in starting this blog. But to explain that, you have to understand the origins.&lt;/p></description></item></channel></rss>
