…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.

In a week, my uncle will throw a Halloween party, so I’ll need a costume. It might have gotten a bit out of hand with two 128x64 flexible LED matrix panels, an additional 180 individually addressable LEDs, two Raspberry Pi Pico 2 Ws and a Bluetooth speaker. It became a costume that changes its look at will.
The video shows the costume in action and demonstrates how it is controlled with an overview of the build. The article here goes into details of the build.

My son loves marble runs, but as he became more interested in Lego than the bigger Duplo bricks, I needed a marble run for Lego. So I printed one. This is a rather simple project, but I stumbled onto an interesting physics detail that I wanted to discuss.
Most of you probably just want to watch the video, but if you want to dive into the physics with a proper mathematical description, the blog article is just right for you.

UPDATE A FEW HOURS LATER: Turns out that Natalie the Nerd beat me to it by a few hours. But she did not just beat me in terms of releasing a bit earlier, but also in functionality, style and execution. I fully admit defeat in this undeclared race that every nerd with a public channel just seems to secretly have competed in. I will be forming a “Natalie beat us” support group with all the other just-a-little-too-late-and-not-quite-as-good projects that will be popping up over the next weeks :)
Well, ok, there actually is a Lego Game Boy and it has just been released today yesterday. What there actually oughta be is a real display for it, which this blog post is about.
If you just want to see it in action, check out the Youtube video. If you want to add a display to your own Lego Game Boy, read on for all the details on how to do this.

Another one of my cousins got married, so it was time for another photo/video booth. This time it uses a Game Boy Camera and a Game Boy Printer.
The video above gives a good overview of the project. The blog entry below contains a few more technical details as well as links to source code and additional resources.

What is the easiest way to create a ROM with a slideshow of your own images for your Game Boy? How about opening a website, dragging your images into the site and hitting a generate button? That’s it. That’s what I created here.
Check out this rather short Youtube video to see the tool in action or just look at the top of this post to try it out yourself.
