Nice! I have to try this, I am always facing this "one tree situation" with my hammock!

I got the same problem. If you have received the email saying your entry has been received I think it worked. In my case clicked several times, but nothing happened... And the next day it has been accepted. But on my profil it still says that I have published 5 times the same entry for this contest!

I like the idea! Do the units stay in place when it is spinning? Do they move?

BTW I also got some problems entering the "fidget spinner design contest", when I clicked on the "publish" button nothing happened... So I clicked many times, then gave up. But few hours later it has been accepted in the contest and now it is available. The only problem is that now on my profil you can see that I have published 5 times the same article!

I got similar problems... In my case I also got the same message "The servers are busy...", then received the emails for the contests and I was wondering if it was published or not. Then after a few hours it was available with the other "recent" articles. So I'd say wait a few hours and it should be okay!

Thanks!

Thank you! Actually it doesn't spin long because I have used plastic bearings. The balls are not completely round because of the printer resolution, and problems during printing. But if you use steel bearings it should spin as a normal spinner!

Thank you!

In french it could be translated as "petite persévérance", which is quite similar!Anyway, the movements on the video are amazing, it looks like it is alive! How much time did you spend to design it?

Thank you! You are right I made a mistake exporting the individual panels... I have re-uploaded the files, it should be okay now :)

I'll give it a try: anyone in France near Marseille? Quelqu'un vers Marseille pour faire équipe?

I agree with this suggestion. I have designed the two panels on different files. And as the panels are quite big (compared to my printer I mean), it would be better to print them separately.

Thanks, I have used this solution. I just hope it is allowed...

Moi non plus je ne savais pas si je pouvais participer aux concours, donc pour mes premiers articles je ne me suis pas inscrit. Puis comme il n'y avait pas beaucoup d'informations, j'ai commencé à participer, mais je ne savais pas si je pouvais gagner quelque chose. Et en fin de compte au bout de quelques articles j'ai fini dans les finalistes.Donc oui il est possible de participer et même gagner en France (malgré le manque d'information) :)

Thanks!

Thanks! Actually I've redesigned some pieces to make them thicker (like the nail). And I've also printed them with another orientation: for example I've printed the nail horizontally so it bends less easily.

This is a funny question! I guess that listening through the windows with a stethoscope might work, as the air compression would make the window to vibrate at similar frequencies. Moreover, I have heard that you can catch a speech behind a window if you are standing far away, just using a laser pointing at the window and analyzing the beam intensity fluctuations of the light. Take a look at this:About the audio fidelity, I guess it would depend on the distance of the speaker from the window, the window thickness, etc... If I can I'll try, and I'll tell you!

Your project is very interesting, and if you have time and motivation I would suggest to build it ;) But as I said before I cannot help you because I have no idea about these module and I don't know how it will react in the configuration you want to build it (the box on the stick). But before you start:If you are not confident with these modules and the Arduino board, it might take a lot of time and you have to be aware of this. It took me few weeks to build mine, because I had to learn how the arduino board works, and how to make the program to control it. Also, it might not work as expected at the end but don't be disappointed! To finish, even if you spend a lot of time on your project, and it does not work as expected, you will have new skills in these fields, that is why it worth gi...see more »Your project is very interesting, and if you have time and motivation I would suggest to build it ;) But as I said before I cannot help you because I have no idea about these module and I don't know how it will react in the configuration you want to build it (the box on the stick).

I have tried the app "mMesure" form the famous petanque brand "Obut", but indeed it takes time to use and it does not give the distance between the objects but just the some numbers according to the position (closest ball is mentioned 1, the second 2, etc...). I have no idea about using such devices in competition, but I think it is not allowed. To be sure the device you proposed gives better results I suggest to simply try the VL53LOX, and make sure it fits for measures on petanque balls. That was one of the mistake I made, I did not try on the petanque balls before to build it (I tried on a glass, but it is different...), and the result was a bit disapointing.

Great job! I am waiting for a video!

Thanks! :)

I don't know if it is better or worse, but anyway it is quite interesting and worth give it a try! ;) I guess it depends on your skills and your knowledge about the VL53LOX and mpu6050. Did you already make projects with these modules? I have never used them, but after a quick research on the internet, the VL53LOX seems to be much better than the ultrasonic sensor I have used. About the mpu6050, it seems more complicated to use as I suppose you will have to add some motors to keep the pipe vertically... Upload a picture and add a comment when you're done with this project, I'd be interested to see how you made it and how it works!
