Using emojis in mathematical notation

Math is hard to understand. Whenever I read technical documents I skip the mathematical equations. When I do read them I have to go over them multiple times to fully finally what the author meant. A major problem is that in my head I have to translate every character back to the concept meant by this character. What makes this…

Building a Jack Skellington Mask

This week it’s Halloween! Time to dress up as something scary! I decided that I wanted to make the mask of Jack Skellington, from “The Nightmare before Christmas“. I used my 3D printer to print a design I found on the internet. In this post I will describe how it went, things I tried, and things I learned.  First of…

Building a Remote Controlled IKEA Table

Inspired by the show Pat and Mat (Buurman en Buurman in the Netherlands) I decided to build a remote controllable IKEA table. For this project I got help from my friend Ilya, with whom we conducted many experiments before we got something which could drive! A long time ago I saw this episode of the show Pat and Mat, in…

LEGO Apollo Saturn V Rocket Lamp

I absolutely love everything related to space! When decorating our apartment we decided to add a little ‘space corner’ in the hallway for all space related decoration. One thing we bought for this is the LEGO Apollo Saturn V rocket. It first simply hang on the ceiling as an amazing decorating piece. However, I decided to spice it up by…

Visualising the PandaSet labels

In May 2020 Scale released their open Autonomous Driving dataset called Pandaset. Of course this is a great opportunity to inspect their data in Virtual Reality with http://immersivepoints.com/. For now I decided to export single frames of lidar data with semantic segmentation, and the raw lidar data with bounding boxes. The Jupyter notebook used to export it is on GitHub. Here…

Building a Cupcake Robot

Currently, as the corona crisis is causing heavy lockdowns, people have to keep a social distance. This made it difficult to celebrate special events, so as a challenge I decided to try to make a contactless delivery robot. The final design was used to deliver cupcakes to my friends! I made the robot itself from scratch with parts I had…

Visualise embeddings in virtual reality

When working with data and neural networks it’s good to know whether similar data is close together. This could be either in the original space of the data or in a deep layer of a neural network. In the last case, we call the data an “embedding” (most well-known for word embeddings). As humans like to look at data in…
