Technik & mehr von damals und heute
A good friend of the older generation of technicians is certainly the analog multimeter of the manufacturer Unigor. In this case, it is the model Unigor_6e from the 70s. An excerpt from the preface of the operating manual: The electronic instrument Unigor 6e combines the advantages of classical measuring technology with those of modern electronics.…

A small mechanics project occupied me this time. It is again about a hot air engine. This time not about the Stirling engine, but the so-called “flame eater”. During the search in the World Wide Web, I found, among other things, the website of Mr. James Maiwald. Mr. Maiwald is an ambitious modeler and specialist…

Now that the front panel is milled, it can be cleaned and the engravings are provided with black paint. After the varnish has dried in the indentations of the engraving, the supernatant paint is removed with solvent. Now the entire panel could be painted with clear lacquer. While the paintwork on the front panel is…

From the years 1970-1972 the radio receiver TEDDY AUTOMATIC 100 comes from the German manufacturer ITT – Schaub Lorenz. It is a multi-band receiver that covers the wave ranges of long wave, short wave, medium wave and ultrashortwave. It is designed for mains and battery voltage (110-127V / 220-240V and for battery operation for 4×1.5…

A patience-related work is the restoration or repair of a rotary pendulum clock. A rotary pendulum clock is, as the name implies, a mechanical clock that generates the clock from a pendulum rotating around its own axis. The vibration energy is transmitted here with a torsion spring (Horolovar spring), ie a very fine steel wire…

After the self-made Geiger Müller counter and the associated experiments, I noticed that there is one or the other radioactive element in our environment. With the SOEKS 01M Geiger counter, an industrially manufactured device, I have now again “scanned” objects in the area. Again, I realized that some of the old clocks in my collection…

In the last two days we received a visit from two young gentlemen from the fourth year of the Villach High School Sankt Martin. Mr. Martin Ungermanns and Mr. Fabian Treu came to us as part of a “taster program” of the middle schools. The two students can participate in the “world of work” and…

It’s time! The first picture of the absolutely real wooden housing for radio electronics is here. A beautifully crafted housing made of glued elements. This work comes from Gebhard’s hands, a master carpenter from the Upper Carinthian region;) Jetzt kann das Nostalgie-Radioprojekt wieder einen Riesenschritt nach vorne machen. The case is on our table. First,…

… to realize the volume control via the microcontroller, a “digital potentiometer” X9C102 was simply used. It is controlled directly by the controller with a “direction input Up / Down” and a “count input”. Internally, this IC consists of 100 resistors connected in series whose “tap” is determined by counting input. So a simple matter…

THE IDEA FOR THE PROJECT A project idea that came to my mind as an ideal apprentice project is to plan and build a radio receiver. With this project, our apprentice should apply the acquired skills in a practical way and set up an FM radio receiver according to the components to be used. This…
