I was always fascinated by event lighting. Maybe not by the tech itself, but the connection you could create between light and music. When I was little I watched a lot of light shows on youtube and always wanted to do those things myself. Over the years I did more and more stuff regarding event tech and so in 2025 I got the idea to create a small light show myself. But using pre-made fixtures seemed kind of boring to me. So I built a wheel, resembling the Wheel Of Mainz (from the coat of arms of my hometown) and put a bunch of LEDs on it. Then I made it controllable via. DMX because the venue I was working with used this standard. I created the lightshow to process the feelings I had at the time. It's a mixture of sexuality and suicidality, originating from my (now Ex-)boyfriend.
You can watch the final lightshow on YouTube (You can skip to 2:40 if you don't wanna hear my speech)

Event tech is mainly proprietary tech. This always annoyed me because I saw how many people wanted to start in event tech but were limited due to tech not being available or cheap. This is why I started a few projects related to Open-Sourcing event tech.
Here, I created an Art-Net Node from scratch using a Raspberry Pi Zero. I used a module to make it compatible with LAN and used a RS485 to TTL converter to send a DMX Signal. There are some projects online which have done similar things. But most of them either don't send a final DMX signal (over DMX 3-Pin) or don't use LAN (with DHCP) which kinda annoyed me, as I see this as a standard for Art-Net-Nodes. The technology I created is based on some other libraries that have been modified to my needs. I didn't use Micropython as it isn't fast enough, so I just used the regular Arduino IDE (ofc the old version, the new one is trash). I currently don't plan on open-sourcing the code as I don't plan on maintaining it and don't want to bother with licenses. You can still contanct me to get the code tho. When I have time in the future, I'll release it ofc :3
Post Scriptum: I know there's an ESP32 on the picture. I tried to get it working with an ESP, but got annoyed by a few libraries, so I switched to a RPI0 later, because I'm more comfortable with that

I played Omori and was very intrigued by Something. While in the story it is not depicted as something (haha) nice, i kinda wanted to build it to look over my room and protect me. So I just drew Something in Illustrator, printed it, placed it on a wooden board we had lying around (idk why my brother and father keep so many wooden boards) and cut it out. Then I just painted it white and then black, stuck some LED strips on its back and asked my brother who is more skilled with his hands how to hand it on my wall.
A few weeks later, I was gifted a new RPI. The most obvious choice to control LEDs in a home is obviously Home Assistant. Problem being that the GPIO pins can't be easily controlled with Pulse Width Modulation. There are already pre-built libraries, that make it easier to use. But this library doesn't support RBG LEDs, which I do use in my room. So I had to use the partly good documented framework of Home Assistant to adjust the library accordingly. I don't plan on making the code public cause it's garbage, but you can contact me if you're interested.
This project is a relatively small one. The building process and programming was done in the matter of an afternoon. Nonetheless, since Something is pretty noticable when you enter my room (and in my opinion very beautiful) I think it still kinda defines me.

I'm a volunteer fire fighter. This in itself is nothing special and pretty normal where I live. But there are a few projects I created to help my local fire brigade - especially in the youth department.
One of the projects I'm most proud of is bftag.stapatum.de (Lang: German). It is a custom built emergency monitor for an event called BF-Tag. It's not a very big project, but one of the most polished ones of me. Currently it's not completly public (you can still create an account if you know HTTP Methods ;3) but I plan on making it available for everyone.
To become a firefighter or get promoted as a firefighter you have to complete a theoretical and a practical test. To make it easier to learn for the theoretical tests, I created feuerwehr.stapatum.de (Lang: German). It's a tool that emulates the real tests for firefighters in my town. Additionally there is a tool to help remember street names and numbers.
My local fire brigade has a youtube channel. I was involved in creating some animations for them. Sadly I don't think I'm allowed to show these on here. In general the fire brigade doesn't appreciate people calling themselves needy catgirls online while simultaniously saying they're part of them :/

smol kitten doin' media

Haii :3 I'm Steffi/Parzival (she/her), but some people just call me kitty. I'm your local needy catgirl. Currently probably doing something including some form of media. My interests are the inner workings of event tech, the social intricacies of volunteer firefighting, the frustrating nature of modern programming and the annoying process of creating designs for people.

I love helping people - and regardless of wether i succeed or not, I'm always self-destructing.
I love seeing people and hate humans.
I'm proud of the things I have accomplished and always feel like they're not enough.
I always see people succeed and it drives me down, even though I want them to succeed.
The human psyche is one of the most fascinating things there is.

programming

Programming was once a pretty big part of my life. But it has become increasingly frustrating. This is partly because of two big factors: the increasing usage of artificial intelligence and me having more friends who also program and always have way too many (opposing) opinions.
Strangers don't make programming better. You'll get always asked: what languages do you program in? Idfk, in all common languages except Rust. If I want to shit out a program in half and hour, I'll use Python. If I'm forced to do web-development I'll do Javascript. For anything performant, I'll use C++. And incase I want to self-harm, I'll do Haskell. Only relevant thing is: I'll shit on all of these languages.

projects

I'm letting YouTube host the videos because they have the necessary copyright licensing deals and I don't.

femboy

I would classify myself as a femboy, even though I don't fall under the traditional definition, since I'm non-binary and a girl (not a boy). But the style I wear is mainly used in these sorts of communities, so I still use this term :3 Here are some pics of me in my femboy outfit.

contact

The most reliable way to contact me is writing me a mail. You can write me using my business mail: stapatum [at] merkel [dot] de. I'll check on it at least every few days.
Alternatively you can reach out via. Discord: @stapatum oder Matrix: @steffi:stapatum.de. I also have some social media channels you can follow me on, but I plan on not posting stuff regularly because it's bad for my psyche :3
