Wind Turbine - Rotation Measurement via Clock face

thingiverse

The rotation energy of my wind turbine is passing to a clock face. The basic files I used are collected from the "Wind energy stored in gravity", but as I want to install the machine on my balcony handrail I change the base in order to have a strong hold on the pipe. Another dramatical change was the wind turbine itself. As I was unhappy with my 2 part printing, I invested time to redesign the turbine. Now, it is possible to print that complete wind turbine in nice quality without any support structures (My prining took ca. 12h with a 3layers and 10% infill - material 178g) I removed the gravity storage and main focus on the idea to measue the wind energy. Via an elastic band I transfer the rotation to my hanging clock "remix of hollow clock project". The hollow clock files were modified in order to insert two bearing to have less friction and to use the weight for the "hour" index hanging always perpendicular for correct function ;) Works great so far.. I am happy with my results... To Rebuild my project you need 6 ball bearings dim (7 x 22 x 8 mm). I only used a very cheap bearing quality but the wind turbine works very well as long some medium wind exists. Maybe if you are using a higher more fictionless quality of bearing it will even start twisting for light air breezes outside... ;) On a very windy day it is possible that the clock (together with the minutes index) rotates 12 times within one hour. That means the hour index have done a complete turn around in that time. .. So for measurement use it makes sense if you observe a certain time gap .. for me an hour is a good indicator so far ... For rebuilds or modifications/enhancements from your side feel free, I will be happy If you leave me maybe a picture or a comment of your work.. thanks a lot..
