@Cem I cannot figure out the airfoil in your picture. (1) Am I seeing the cross section of the black object which I guess is the wing, and (2) Is the wind blowing perpendicular to the picture, ie, towards the viewer?
I have never seen any real wind tunnel. So I wikied and saw a picture of the real thing. Actually earlier when you told me "the whole experiment is rather a disaster and tomorrow I'll be taking everything apart, ...", I immediately thought of the Wright Brothers who finally succeed flying, after many many disasters, ... :)
I was curious to know more about wind tunnel, so I am searching further. I searched three forums, rpi.org, rpi.se, and ee.se but found nothing in wind tunnel. I then tried "hx711" and found many useful references.

Ah lunch time. See you late this afternoon, evening, or tomorrow. Cheers.

hi, sorry couldn't test anymore, have already taken everything apart. Happy to share photos of it if of any interest. Will not attempt another one :). Was a pleasure to meet you and to have a great chat !

No problem at all. I have learned a lot from you. I will study more about the wind tunnel and perhaps do similar projects later. Please feel free to ask me for updates any time on hx711 projects. Best wishes. Cheers.
