I've probably already mentioned at one point or another that it was important to me to be able to control WinDIY safely and also limit its speed in an emergency. <\/p>\n\n\n\n

To do this, I developed a mechanism that makes it possible to adjust the angle of attack of the wings. This allows the blades to be adjusted to the current wind and rotation speed. They can also be turned out of the wind in strong winds. <\/p>\n\n\n\n

This allows you to control the speed and load of WinDIY.<\/p>\n\n\n\n

I have written down some additional information about this here: https:\/\/hackaday.io\/project\/172328-windiy-hawt-wind-turbine\/log\/179105-windiys-hub-oh-my-god-mechanics<\/em><\/strong><\/a><\/p>\n\n\n\n

In the following article you will find instructions for replicating the mechanics for adjusting the wing angle of attack.<\/p>\n\n\n\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

Collect required parts<\/h2>\n\n\n\n

Before you can start building the hub and its mechanics, you must of course first have all the necessary parts together. You can find a complete list of the materials and tools required above in the materials and tools list<\/p>\n\n\n\n
