The exhibit shows an unorganized movement of the pendulum in self-intersecting magnetic fields. It is never certain what will be the next direction of movement of the pendulum. Stainless steel built, nearly 2m long pendulum with strong neodymium magnets. Date: 24th August 2014
Interactive exhibit with integrated control touchscreen. The system is used for scanning the floor of the pool and the objects inside. The gathered data is shown on a 3D plot. We developed a software to control two stepping motors, position sensors and a laser telemeter. The control unit was created based on an arduino controller…
This two-element exhibit is used for investigating the reaction time. The first part examines how fast one’s pupil reacts to a change in light intensity. A fast camera is used to capture the pupil’s movement. A graphic representation of the examined parameters is shown on the screen. It is possible to save the result and…
This exhibit lets you see through everyday appliances. over the screen there is a see-through slider. When sliding it over a device on the screen, it’s cross-section is shown. The cross-section of a battery also contains the chemical components in it’s cell, and a visualisation of the electron transport inside. Date: 24th February 2015
This educational exhibit shows the dependancy of the travelling sound waves on the density of the medium. After the system is activated, an alarm signal can be heard from the speaker under the glass dome. A microphone mounted inside is used to examine the sound’s intensity. A vacuum pump is activated with a button and…
This educational exhibit consists of a plywood board with two supports. On this simplified bridge, an vibration inductor is mounted. Using the embedded touchscreen, one can change the frequency and amplitude of the vibrations to find the resonance. An laser indicator is also used, to help observing the amplitude of the movement. Date: 3rd March…
This exhibit shows how an optical fiber works. Under the dome there are plenty of tangled fibers. The goal is to connect the light source to one of the inputs and trace the illuminated fiber to the point it exits the dome. Date: 7th July 2015
This educational exhibit show a stationary wave effecty. A speaker is mounted to the tube, and sine wave is emitted. The goal is to find the resonance frequency. When doing so, one can hear the sound getting louder and observe the styrofoam balls in the tube move in an impressive way. There are two ways…
This educational exhibit shows how the hearing changes with age. You can examine your hearing and determine the “age” of your ears. The sound frequency is changed with a large slider. The slider should be swiped to the right, towards the higher frequencies, until you stop hearing a sound. On the scale along the slider…
Educational exhibit for the Hevelianum science centre in Gdansk. Suitable for high school graduatees and beginner college students. Wind tunnel is meant to examine the lift and drag forces acting on a plane wing model inside the chamber. Our part of the work was to design and manufacture the electrical strenght measurement system. The module…
