Operating Instructions:
- The device turns on automatically, centrally, along with other entertainment elements in the MOTIO center.
- The device has multiple programmed modes. These can be changed during inactivity by pressing a button, with the currently selected mode displayed on the LED indicator in the button.
- Press the button on the worktable to select:
- Red mode – MAXIMUM
- Green mode – VOLUME
- Press the button on the worktable to select:
For modes evaluating measured data, the activity starts by blowing into the anemometer – the speed must exceed 1.5 m/s (the first LED on the pole lights up).
Mode 1 – Maximum
The LED indicator on the button lights up red. RGB LEDs display the maximum recorded blowing speed according to the table.
- Green LEDs: 1 to 5 (1.5 m/s to 5.5 m/s)
- Yellow LEDs: 6 to 9 (6.5 m/s to 9.5 m/s)
- Red LED: 10 (above 10.5 m/s)
The speed of the small propeller changes according to the number of lit LEDs. Only the maximum recorded speed in the game is displayed.
- 1st LED: above 1.5 m/s
- 2nd LED: above 2.5 m/s
- 3rd LED: above 3.5 m/s
- 4th LED: above 4.5 m/s
- 5th LED: above 5.5 m/s
- 6th LED: above 6.5 m/s
- 7th LED: above 7.5 m/s
- 8th LED: above 8.5 m/s
- 9th LED: above 9.5 m/s
- 10th LED: above 10.5 m/s
The maximum recorded speed during testing was 12.2 m/s.
Mode 2 – Volume
The LED button indicator lights up green. The player has limited time to light up the whole LED display. LEDs light up gradually, according to the amount of air blown. Once the maximum is reached, the propeller spins. The volume of air is calculated from the current speed, and the number 120 must be reached.
„Slowdowns“ of data from the probe are not added to the total.
During long periods of inactivity (no game in progress), the device simulates energy generation – it lights up the LEDs and spins the propeller. The demonstration mode randomly simulates changes in blowing speed.
Interactivity:
A model of a small wind turbine, utilizing the visitor’s breath blowing into a small anemometer. By converting the rotations to a large propeller, it moves electrically, making several rotations depending on the force. The effect is also displayed in the form of lighting up LED panels according to the force of the visitor’s breath or the set interaction mode.
Educational Significance:
Fossil fuels versus renewable sources. The former harm the environment and are noticeably depleting, while the latter are less efficient and variable in strength – somewhat temperamental. Sun, water, wind. The availability of energy is increasingly urgent, and alternatives, at least on a small scale, take time reaching the consumers. Even a small wind turbine in the garden can be useful, slightly relieving the public grid. And what if there were hundreds, thousands of them? Visitors can try out how much work the airflow – wind – must do to start a pump or at least make a microwave work – that is, to spin the propeller, on the exhibit „Wind from Breath.“
