Deskbreeze is a lightweight and simple wind tunnel for teaching aerodynamics to children and adults.
Last summer, Gerhard’s daughter attended a sailing course for children. She was six years old and would enter school the following autumn. She could not read and write and therefore had trouble understanding the written course materials and the graphics. So Gerhard thought about a vivid method to explain to her the basics of aerodynamics for sailing.
Gerhard built a wind tunnel of cardboard and straws, attached to a little fog machine. It worked well, but wasn’t perfect. Through several iterations he developed a stable and simple wind tunnel, into which you can put different objects. With a simple turntable and wires you can change courses and the position of sails, for example.
Deskbreeze uses fans and honeycomb cores to create a laminar flow, and dry ice for the visualization of the airflows.
A security system that detects the mobile phones of the home occupants in order to avoid switching it on and off. This home made project uses Raspberry Pi, motion detection and naturally MakerBeam.
One of the main goals was to have the system completely automatic. No turning it on or off when leaving or arriving home. The easiest way to achieve this was to try and detect the mobile phones of the home occupants. Conceptually this was quite simple but in practice it was the most challenging part.
You can read the complete Bill of Materials in the full article. Continue reading on hackster.io about this project with raspberry pi.
For Gerhard the windtunnel started as a teaching device for the youth sailing weeks of his sailing club. The prototype was presented at the 2016 Maker Faire in Vienna where he received positive feedback. He plans on starting a Kickstarter campaign in the summer of 2016.
You can easily show airflows at a sail or the wing of an aeroplane with the mini wind tunnel DeskBreeze. You can use the wind tunnel as a teaching device.
The idea for the wind tunnel was born in 2015, for the youth sailing weeks in our sailing club (Nautic Club Austria). Gerhard Fließ built a prototype made from plywood and cocktail straws and was surprised by the smooth airflow in the wind tunnel. In 2016, he developed the current version made from aluminium profiles and honeycomb.
He presented the wind tunnel at the Maker Faire 2016 in Vienna, where he got very positive feedback. Therefore, the “gimmick” for himself shall become a project for all.
In 2016, Gerhard will start a project on kickstarter, where you can support a kit.
