Analysing my swim stroke

Recently I tried to improve my swimming skills. I’m trying to get better at longer distances, swimming with less effort, and going a bit faster. In some videos they talked about optimising the amount of strokes you take per minute, and your pace per 100 meter. Apparently there is a certain sweet spot you have to hit, and there are…

Landing the perseverance rover on mars

This week the perseverance rover landed on mars! A big congratulations for everyone at NASA who made this possible! It’s a stunning engineering feat which I followed closely on Youtube. Something I noticed is that they mentioned they can land the rover more precise than last time because they use visual localisation (‘terrain-relative navigation’) during the landing. Last week NASA…

Sending a Neural Network to the Moon

Sending a neural network to the moon I absolutely love space, and am obsessed with the moon. Last week /r/Valphon on Reddit posted that he ordered a “moonbox”. Apparently a company called Atrobotic, together with DHL, is offering to send things to the moon for quite an afforable price. He is giving out 10MB of storage space on a first…

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…

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…
