Technik & mehr von damals und heute
Some projects arise from a spontaneous idea, while others develop over months. Our mini arcade machine definitely belongs to the second category. It all started on a cold winter day when my son and I sat down at the kitchen table to start another little craft project. At the time, we had no idea that…

Since I’ve been working on home automation, I’ve naturally wanted to optimize and simplify as much as possible and adapt and implement it in line with the new buzzwords “green electronics”, “sustainability”, “energy-saving” … and so on. For example, my appliances switch off when they are not used or ignored, stand-by energy consumption is largely…

In the article “Pylontech PV battery status in HomeAssistant”, I had improved the project “Pylontech battery monitoring” of the following GitHub links and drew a circuit board to make the whole construct a little more compact and professional. https://github.com/irekzielinski/Pylontech-Battery-Monitoring https://github.com/hidaba/PylontechMonitoring All battery data of the Pylontech battery modules are displayed in the Homeassistant. Great! But…

Little by little, I am bringing many of my smarthome components to a common standard. I have decided to bring all devices together via a NodeRed server. The HomeMatic system also communicates with NodeRed. Among other things, I also transfer the measured values of the EVU meter (I have a Siemens IM350 smart meter installed)…

It’s been some time again that I manage to find time and energy in the later evening hours to write here on the blog about one of my little projects. Over the past few years, I’ve gotten into the habit of listening to podcasts during car rides and at night. These primarily include podcasts on…

Update: April 2025 projectfiles shared on github: https://github.com/ingmarsretro/db50xg_supplyboard Rummaging through a box of my old crafts I found the box below. It dates from the time when I was still working with Amgia, but also with PCs – I guess around 1996. I labeled the box “DB50XG MIDI – Wavetable Processor”. Inside is a circuit…

The fact that the topic of retro has become more and more of a trend in recent years has not escaped me either. The “Industrial” and “Steam” style has also found its way into many households. People put many things on the shelf again, which represent the robust technology and the appearance of the past…

Since my leisure activities are increasingly taking place outdoors in the currently somewhat warmer season, writing the weblogs suffers a little. But I’m still working on some projects, repairs and restorations. In this way, a lot of material comes together again in order to write articles from it – in the colder season of the…

edit Nov. 2024: I keep receiving requests to make the Gerber files for the circuit boards available for reproduction. The download is now possible with this link: vectrex_rom27c1001 For the Vectrex game console a home arcade machine from 1982, there were, or there are a very limited number of game titles available. I will present…

A few years ago I presented a project in which a Raspberry Pi was working as a data logger. A few sensors were connected to this Raspberry, which recorded environmental data such as air temperature, relative humidity, air pressure and the current GPS position. The sensors mostly consisted of ready-made breakout boards that were connected…
