Technik & mehr von damals und heute
An interesting problem has arisen with the measurement technology in the laboratories at my workplace. I use the term “measurement technology” to describe the equipment of a laboratory workstation for basic training. There are a total of nineteen laboratory workstations, each equipped with two laboratory power supplies, two desktop multimeters, a Keysight signal generator and…

In an old post from 2019 I reported about oscilloscopes from the manufacturer Keysight and their problem with a sudden failure. (see link). At that time, it was about oscilloscopes suddenly refusing to work – sometimes with a bang and subsequent smell of “power”. Or simply nothing happened at all after switching on. The reason…

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)…

When summer comes, new ideas come. In the summer months, as is well known, the duration of sunshine is longer and the intensity of the sun’s rays is higher. Many use this property of the sun to boost their body’s vitamin D production, while others lie under the source of radiation to darken their skin…

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…

The title says it all. I am looking for the RUN/STOP button for a Commodore Plus 4 computer. The model that I prepare is already finished except for this missing button. I’ve looked on the bay and at flea markets, but nobody can help me there, or you can get whole keyboards, but unfortunately at…
