- Piskač V.: Three new experiments, Fair 12, Praha 2007The first part of this contribution is a demonstrative experiment –a light bulb rheostat changes a current in a circuit. The second part deals with acoustic devices (Seebeck siren and monochord), demonstrated by electromagnetic detectors.
- Válek J., Sládek P.: How to draw 2D oscillations and Lissajous curves using 3D projection, Fair 16, Olomouc 2011This contribution presents possibilities of dynamic modelling that was developed using PHP for composition of perpendicular commensurable oscillations in a plane. Modelling is accompanied by a real 3D model realized on a transparent foil, with whose 2D projection one can verify the result with students.
- Vícha V.: Utilization of a microphone for measurements in mechanics, Fair 9, Brno 2004Two laboratory exercises with a microphone connected to a sound blaster which is used for an accurate measurement of short intervals.
