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 get some insights into the technology.

The program included work such as assembling and soldering of electronic kits (the well-known shaker cube), a small series work (flashing of PIC microcontrollers), exposure and etching of circuit boards, milling of aluminum plates.

As conclusion of the two taster days both high school students were allowed to build up a complete “device”.

It was a “clap switch kit” that detects a loud sound event via an acoustic sensor and then turns on a relay contact. So that this circuit can also be used meaningfully, the circuit has been extended by a self-made power supply, all installed in a plastic housing and equipped with power cable and Schuko coupling. So any consumer (eg a floor lamp, TV) can be switched on and off with this switchgear by simply “clapping” …
