Low latency and high FPS camera stream with a Raspberry Pi

I just saw that two very good sources, that both had an article about this topic, have gone offline without an archived version. And because I continued my work on a robot that is controlled by a Raspberry Pi, I had to figure out how to create a low latency and high FPS stream from the Pi’s camera that can be viewed in a web browser again.

2018: Annual nerdhut Christmas letter

This year was a mixed one for the nerdhut. Even though I finished interesting projects, helpful articles and informative videos, I feel like there could have been more. Unfortunately, I was pretty busy this year and didn’t have as much time to write articles, as I would have liked to. Anyway, let’s see how the site performed this year!

Read smartphone accelerometer data on a website

Almost everybody has one nowadays: A smartphone. But how often did you come across a website that used the phone’s tilt sensor? More than often enough a website only changes the layout if tilt your phone. How cool would it be, if the background would move around slightly when you tilt the phone? This short article will show you how to read the phone sensors and how to process the data with JavaScript!

C sockets – A hello world introduction

While sockets are no new concept for me, I recently had to write an application in C that uses sockets to communicate. And while trying to figure out, what the best way of doing so is, I came across a lot of tutorials. But most of them either completely missed the point, were too complicated or used obsolete functions in the code. In this article, I want to try to give you a simple and short overview of sockets and an up to date ‘hello world’ example for a client and a server application.

Raspberry Pi 3G using a Huawei E303 modem and DynDNS (English)

Long-time readers of this website might recognize this article. It was the first article, I published on nerdhut. As of today, this is still one of the most popular articles on the page and because of that, I decided to shorten it a bit and translate it to English.

However, the original German version remains online here!


Due to my work on a remote-controlled unmanned ground vehicle, I searched for a way to control it anywhere in the world. Because I wanted it to have a high range and reliability, I decided to communicate with it over the internet, which should be available almost anywhere on the planet. Continue reading Raspberry Pi 3G using a Huawei E303 modem and DynDNS (English)

Nixie tube thermometer – Part 3

In the third part of this series, I want to talk about the PCB design and the custom case for the electronics. I’ll also revisit the transistor array, which I didn’t finish in part 1 of this series and I test the completed project and show it in action. Continue reading Nixie tube thermometer – Part 3
