There oughta be…

…a blog with awesome projects. A collection of overcomplicated devices nobody needs. A sanctum for all the things that did not get living room clearance, but oughta be seen by fellow nerds.

There oughta be a Live Q&A about the WiFi Game Boy Cartridge.

28 January 2022

There will be a Live Q&A session about the Game Boy WiFi cartridge on Friday 9pm (CET). Ask anything!

I have never done this before and am quite curious on how it will turn out and how many will attend. See you on Friday!

There oughta be GTA5 for the Game Boy.

13 January 2022

When I presented my WiFi Game Boy cartridge a few weeks ago, I only had very few simple text-based demos. This post and especially the accompanying video now deliver more. In fact, I might have gone a bit too far, as I managed to stream full resolution video and even play games via WiFi. But see for yourself:

So, as usual, you have two alternatives to start here: Watch the video or read the article. If you are just curious and want to see what I did, definitely check out the video. If you want to understand exactly how it works and if you want to reproduce it or find tricks for your own projects, go for the article and the linked code. In any case, if you have not seen the previous article and/or video on the cartridge itself, you should start there.

There oughta be a WiFi Game Boy cartridge.

16 December 2021

It took a while, but I finally managed to create my own Game Boy cartridge. With WiFi! At this point, it can only demo a simple telnet-style communication and access Wikipedia articles, but I am confident that I will showcase more in the future. For now, the interesting and surprisingly tricky part is how the thing works at all.

If you just want to see the cartridge in action or want to get into all the details, I highly recommend to watch the video first as it goes through the difficulties and their respective solutions. In contrast, this article here is less visual in its explanations and mostly documents the device in detail, so unless you are already familiar with the parallel memory interface of the Game Boy, you might want to start with the overview from the video.

There oughta be a Blender plugin to animate growth.

24 May 2021

I have created a Blender plugin that takes an image texture with some structure and generates an animation of how this structure grows. To be more precise, it creates a non-color data image with the animation information that can be used in a shader. Since animations are hard to describe in words or individual images, I highly recommend the video describing this plugin.

If you are only looking for specific information or the download of the plugin, have a look at this article. It serves as the documentation, but it will have only little explanation of how the plugin works and how the results can be used. Refer to the video for these details and to see how the plugin is used in Blender as shown in the actual Blender user interface.

There oughta be a smart doorbell.

05 April 2021

As all package delivery services in our area have conspired to ring our doorbell just when the kids are having their afternoon nap I decided to smarten up our doorbell. To do so, I created a small PCB that goes into our in-house phone to disable it, trigger other IoT devices if someone rings the bell and to trigger the door opener. You can get an overview in the accompanying video or just read the article.
