    I finally am a full member of the internet – I am the proud servant of two cats! To keep them entertained when me and my wife are at work, I built a web-controlled laser-turret: At its heart is an ESP2866 on an nodemcu amica v2, a cheap servo pan/tilt kit with small 9g servos and…

    In order to be safe, reliable and fast, autonomous cars need to be able to perceive their environment and react accordingly.

    It is quite challenging and costly to build up a robot lab, especially if you just want to conduct some experiments with sensors and a moving platform. In todays search of affordable robot platforms, I discovered MORSE, a simulation platform built on the blender game engine (www.openrobots.org/wiki/morse/). This article will show how to set it…

    I had a little free time on my hand and decided to quickly complete the coursera-course “Data Science at Scale – Practical predictive analytics” of the University of Washington by Bill Howe. The last assignment was to participate in a kaggle competition. For this assignment I chose the “San Francisco Crime Classification” challenge. The task…

    So I also decided to build myself a smartmirror. However, I want it to provide a little more functionality than just displaying some information and telling me that I’m beautiful. Here is the finished build: And here is a video of the leap-motion-control in action: I want to place it in my bathroom, because that’s…

    For my new flat I wanted controllable RGB LED stripes. Problem is, most of the controllable cheap ones only have IR remotes, so the receiver must be in line of sight of the remote somehow. That has several drawbacks: you cannot install it behind some furniture without the receiver sticking out, and synchronizing across several rooms is hard.…

    After fiddling around with some ultrasonic sensors for S.A.R.A.H. (my home automation system), I was looking for other options. Thanks to ebay, industrial laserscanners are now an option :) In this article I will describe how I connected the scanner with a regular PC, got the password, and provide a python-class that is able to…

    Today I will try to detect some lanes.. Assumptions: – We know the lane-width (plus minus) – We are inside the middle of a lane – We know the camera geometry – Based on the turnrate of the IMU we can estimate the curvature of the street – A line in pixels can be detected…

    I spent some time on training several cascades to detect cars in ego-view automotive videos, and will now document what I’ve learned. I will use the existing OpenCV-tools. Data preparation ./cascadetraining/ -> pos/ 1000 images containing the desired object -> pos.info (containing the filenames of the objects, number of objects in the frame and bounding…
