Green Lightning

Shelf

Mon, 10 Nov 2025 18:00:00 +0100

Seeking ever more usable surface area in my storage room, I set out to build an extension for the shoe rack that was already in place. My hobby woodworking adventures are documented in the following. But first I shall spoil you with a picture of the end result.

Marble Gate

Mon, 10 Jan 2022 23:20:14 +0100

Inspired by Wintergatan I designed, 3D-printed and built this Pac-Man Marble Gate.

I obviously got the idea for the gate from the Wintergatan videos (here is a live stream where Martin designs the gates for the Cyberbass), but I created the 3D design for this project from scratch in Fusion 360.

Piano Headphones Holder

Fri, 26 Nov 2021 13:55:41 +0100

I needed a better way to store the headphones for my digital piano, because I would just place them on the keyboard, which did not look nice, and they would get in the way when using the built-in speakers.

Final Result

I started by building a prototype from cardboard and a toilet paper roll to verify if my design would work and to check the dimensions. I was planning on 3D printing this project, however it would be difficult to fit inside the small build volume of my SLA printer. But then I realized how I could build it from wood, so that is what I did.

Plot Party November 2021

Wed, 24 Nov 2021 23:06:06 +0100

Two weeks ago I took part in Plot Party, which is a pen plotting art challenge (sort of like a game jam for pen plotter art). I posted a lot on social media, so I thought it would be good idea to consolidate everything into one blog post.

Grnch

Thu, 11 Nov 2021 12:00:39 +0100

Grnch is a command line tool and Go library for generating and working with G-Code for pen plotters using the grbl firmware.

The command line tool can post-process G-Code exported from Inkscape (using the gcodetools extension) to make it ready for plotting. It also features an advanced G-Code simulator to estimate plotting time, that simulates grbl’s line planner and takes acceleration into account, which makes it more accurate than other time estimators.

Improving Inkscape Startup Time

Fri, 27 Aug 2021 16:00:10 +0200

While Inkscape is a great vector editor, its startup performance on Windows is terrible, often taking 5 seconds or more to open an empty window on my computer. Investigating the application startup seemed like a fun project to get familiar with Event Tracing for Windows (ETW) and related tools. I think I found some interesting results, so I decided to write this report.

Geometric Studies on Pen Plotter

Tue, 04 Feb 2020 16:00:00 +0100

Complex shapes emerge from geometric primitives. This is my latest plotter project.

Original print time was 21 minutes. The video is sped up 24x.

Here is a picture of the final product:

Advent of Code 2019 ASCII Art Plot

Tue, 07 Jan 2020 14:00:00 +0100

I got a CNC machine for Christmas, which can also be used as a pen plotter. My first project was this giant ASCII art mashup of my Advent of Code 2019 solutions:

Here are some pictures of the final product:

Advent of Code Solutions

Fri, 03 Jan 2020 18:12:00 +0100

I enjoy participating in the Advent of Code event every December, which is digital advent calendar challenging you with a two-part programming puzzle every day.

In 2019 I aimed for the global leaderboard and finished at rank #51 of the world, which I am quite proud of.

Daily Frustrations

Tue, 29 Oct 2019 19:59:25 +0100

I want to work on an assignment for university, that requires LLVM and makes use of their integrated tester (llvm-lit).

llvm-lit is written in Python. I have some version of Python 3 installed, so I try to run it using the py launcher for Windows. I get no output and no errors.

Hard Bugs

Tue, 30 Jul 2019 15:58:06 +0200

A few years ago I stumbled upon my first hard bug. I was working on my custom C++ 2D game engine and had just added the ability to render to an off-screen image. But it was not working well and most of the time I would get a black image. After stepping through the code for a long time, I inspected the camera data again and noticed that the projection matrix looked quite odd. Investigating a little further the root cause was determined: the projection matrix was uninitialized, rendering all further draw commands useless.

Green Lightning 1.4 - The Double Update!

Sun, 03 Jul 2016 13:14:20 +0200

There’s a new update for my Minecraft resource pack . This update covers Minecraft 1.9 as well as Minecraft 1.10! Here’s some of the new stuff:

Boats!

Beetroots!

Redstone!

LD34 Results!

Sat, 09 Jan 2016 17:28:49 +0100

The results for Ludum Dare 34 are here!

My game, Robot Boxing, got the following ratings:

Coolness: 26% (#2073)

I took part in the jam this time instead of the compo, because I didn’t have the whole Saturday available.

LD34 Entry: Robot Boxing

Thu, 17 Dec 2015 15:54:49 +0100

Robot Boxing is my entry for the 34th Ludum Dare game jam. It was created in less than 72 hours on December 12-14, 2015

In this game you are a robot punching random things in front of a hopefully appealing parallax background.

LD30 Results!

Tue, 16 Sep 2014 18:54:02 +0200

The results for Ludum Dare 30 are here! My game, Labyrinth Challenge, got the following ratings: Coolness: 60% (bronze)

Rank (1493 compo games / 2538 total)	Category	Stars (out of 5)
#562	Theme	3.25
#747	Graphics	2.81
#788	Overall	2.97
#811	Fun	2.75
#866	Audio	2.04
#887	Innovation	2.71
#915	Mood	2.55

I was not as good as last time , but I’m still happy with the result, because at the end of the first day I felt my game was really terrible. But during the second day it got better than I thought it would ever get and the ratings aren’t totally bad either. Additionally, I never did procedural generation before and learned quite a lot this time.

Green Lightning 1.3 - The Bountiful Update!

Tue, 02 Sep 2014 22:18:27 +0200

There’s a new update for my Minecraft resource pack .

LD30 Entry: Labyrinth Challenge

Mon, 25 Aug 2014 13:36:24 +0200

Labyrinth Challenge is my entry for the 30th Ludum Dare game jam. It was created in less than 48 hours on August 23-24, 2014. In Labyrinth Challenge you navigate a multi-dimensional maze trying to find the treasure. Each maze consists of three worlds, the top one has grass floor, the middle one dirt floor and the bottom one stone floor. The teleporters connect the worlds. Blue teleporters will bring you to the world below the one you are currently in and the orange ones will bring you to the world above. The mazes are randomly generated. Once you have beaten a maze, the difficulty increases and the next one will be bigger. Here’s a gameplay screenshot.

LD30: Schedule and Setup

AsteroidsGDX 1.0

Sat, 26 Jul 2014 16:28:43 +0200

AsteroidsGDX is an action game where you have to maneuver your spaceship around dangerous asteroids flying through space while collecting pickups and shooting bullets to reach a new high score.

Background

After programming an unfinished Asteroids prototype as a warm-up exercise for Ludum Dare 29, I decided that this would also be an appropriate way to get me started using LibGDX . So I took the graphics from the old project, but started coding on a new and empty LibGDX project. This time things went a little different. To handle the collision checking I used a complete physics engine this time. I already knew dyn4j from previous projects, which is why I choose that over Box2d which is the usual physics engine to use with LibGDX, so that I didn’t have to use yet another new API. Having the power of a full blown physics engine, I thought it would be nice if asteroids would not glide through each other, but to prevent them from sticking together I made them very bouncy. This had the desirable side effect of making the game more interesting, because if two harmless looking asteroids collide there’s always the risk that one will bounce in the direction of the player.

LD29 Results!

Tue, 20 May 2014 12:21:55 +0200

The results for Ludum Dare 29 are here! My game, Pelican Challenge, got the following ratings: Coolness: 71% (bronze)

Rank (1491 compo games / 2495 total)	Category	Stars (out of 5)

#372	Overall	3.36
#385	Mood	3.18
#399	Theme	3.44
#613	Humor	2.36
#767	Audio	2.33

Considering that this was my first Ludum Dare, I’m extremely happy about the results xD

LD29 Entry: Pelican Challenge

Mon, 28 Apr 2014 00:32:18 +0200

This is my game for Ludum Dare 29! In Pelican Challenge you have to dive into the water to catch as much fish as possible within one minute!

Downloads

Controls

Click the game to give it focus. Dive to catch fish. If you dive from further up, you dive deeper. Normal fish give you 1 point, the larger ones give you 2. If you hit a jellyfish, you loose 5 seconds of your precious time, but you get 5 additional ones if you catch a pink fish.

LD29 Day 1: Introducing Pelican Challenge

Sat, 26 Apr 2014 23:11:21 +0200

Ludum Dare has been great so far! The theme is “Beneath the Surface”, so I have created Pelican Challenge, where you have to dive beneath the surface of the water to get the desired fish.

LD29 Warmup: AsteroiDare!

Fri, 25 Apr 2014 22:44:25 +0200

I’m going to take part in Ludum Dare 29 and have created AsteroiDare as a warm up exercise.

For the game jam I’m going to use Haxe , OpenFL and HaxeFlixel as programming framework, Sublime Text for coding, Gimp for graphics and Bfxr for sound effects. I also prepared a template , so I can start coding the interesting stuff quickly.

Description

The arm can rotate and move up and down. It first grabs a ball from the dispenser, which pushes one ball from the shelf when the arm hits the beam at the front. This is done mechanically via a construction of beams.

Ownership, Licenses and Violations

Sat, 07 Sep 2013 22:50:42 +0200

As you might know, I’m the creator of a Minecraft resource pack (What is this? ). I put a lot of time into it and the effort pays off as I’m getting a lot of downloads. Resource packs are of course property of their creator. I respect the creators of other resource packs and do not for example reupload their packs using my name. I expect people to have the same respect for my resource pack as well (and also for all my other work). The earlier versions of my resource pack contained some textures from other resource packs. I made sure that the licenses of these resource packs explicitly allowed me to include some of their textures in my resource pack and I gave credit to the original creators. I also allow other artists to use some of my textures in compilations or in their own resource pack, if they give credit to me. In a tutorial about resource packs I was advised to choose or create a license for my resource pack. It is generally good to use an already existing license, but because none of the common ones was exactly what I wanted, I decided to put my understanding of ownership and respect in simple terms and use that as a license, which is now displayed on each download page and is part of the download itself. The most important part of said license is: Do not reupload my resource pack. Although I know the internet is a very strange place, I was still very hurt, when I was told that exactly this rule had been violated. A this point I want to throw a big thank you at insomniac_lemon for pointing this out to me and for helping me resolve the issue. Anyway, my resource pack could previously be downloaded via it’s Minecraft Forum thread only, but insomniac_lemon spotted it on Planet Minecraft . It was uploaded by a stranger with a random looking name and was getting lots of downloads and diamonds there. Thankfully I did not discover the fake myself, but it was shown to me by a very supportive and nice person, so I had help from the very beginning. insomniac_lemon then reported the fake to the moderators of Planet Minecraft. I wanted to do something as well, so I decided to take the opportunity to post my pack to Planet Minecraft myself and it’s been getting a lot of attention from the Planet Minecraft users. As you can see there are also friendly people on the internet and although there’s a saying which goes like ‘100 positive and 1 negative comment will still make you unhappy’ you should never allow such an incident to stop you from doing what you like, but instead use the opportunity, do something creative and make the best out of it.

My Three Greatest Minecraft Builds

Wed, 31 Jul 2013 18:00:21 +0200

These are my three greatest Minecraft builds so far.

I posted each image twice, once using my own resource pack and once using the default look of Minecraft. Just look at what you like better :)

This collection is also available as an imgur album .

Green Lightning 1.1 - Logs and HD font!

Sun, 07 Jul 2013 17:42:06 +0200

There’s a new update for my Minecraft resource pack !

This version was mainly created to put my custom hd font back into the pack, which was not included in version 1.0, because the hd font feature was broken in Minecraft 1.6.1, but is now fixed with Minecraft 1.6.2.

Hot Wheels Store

Mon, 01 Jul 2013 18:00:53 +0200

This is a warehouse for Hot Wheels cars. In real life such a robot could be used by car manufacturers, in really cool car dealerships or in automated under ground parking decks/parking garages.

What Is a Minecraft Resource Pack?

Mon, 01 Jul 2013 15:00:08 +0200

A resource pack is a collection of images and other files which determine how the game looks. Here’s an example: The bottom/right half of this image shows how this scene looks with the default textures, while the top/left half shows how it looks using my resource pack . Resource pack creators use image painting and editing software like GIMP or Photoshop to digitally draw and paint these images (i. e. they mostly do not use a camera, but start with a completely white or transparent image) and thus the creators are (digital) artists. Resource packs are *not *mods. Resource packs only change the look of the game, they do not change the game mechanics, e. g. you can’t add new blocks using a resource pack.
