I finally came around finishing this project and I also made a video in which I explain the build and also show you how to assemble the project. This article covers the case design and some changes in the source code in more detail compared to the video.Continue reading USB volume knob for Windows, Mac OS and Linux – Part 2
I enjoy building these kits and so I thought that it was time for season 2 of the banggood stuff webseries. This episode covers a 15$ oscilloscope kit you have to assemble yourself:Continue reading Banggood stuff – Season 2
I just saw that two very good sources, that both had an article about this topic, have gone offline without an archived version.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.Continue reading Low latency and high FPS camera stream with a Raspberry Pi
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)
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
It’s been a while since I published this series of articles on nerdhut about monochrome video signals for an old Macintosh CRT. I wanted to post a short follow-up article about VGA and how to generate such signals. This article will also be a follow up to the custom CPU series and it will be another step towards the custom computer, I always wanted to design and build.
However, in this article, I only want to take a look at how the standard 640×480@60Hz VGA-Signal can be created using a screen testing device, made from discrete electronic components, which can be used to test monitors without the need of a computer being around. Continue reading VGA signal generation using discrete electronic components
In this part of the series I’ll discuss how to read data from the temperature sensor, make the Arduino react to claps and I’ll also go over the software that controls all these features and then displays the right numbers on the Nixie tube display. Continue reading Nixie tube thermometer – Part 2
