Powerful but inexpensive function generator for student experiments, for use in electronics, but also in mechanics and acoustics for operating motors or sound sources; 
in combination with a multimeter that can measure a frequency, you have a function generator with a digital display; 
the external power supply unit is RiSU-compliant and therefore enables a safe mains connection.
