When you look at the proposed homemade by Instructables under the nickname RickiDuff842, the first thought comes up like this: but what's the point? And the second - well, his, this meaning, when such a beauty happened. Just like Calder's Mobile in Office Romance.
The master does not give any sizes of details in the description, but the following photo is enough to repeat the device do it yourself. Repeating on a scale of 1: 1 is still not required, but you can approximately determine the size by proportions, given that in the original the smartphone installed on the design is iPhone 4s.
So, the base, preferably, of course, with legs. You can round, you can oval, rectangular or square. Then - two identical vertical racks. And three concentric flat rings, between them there are gaps of five millimeters. The outer ring is connected to the uprights by means of horizontal axes. The middle with the external is connected by vertical axes. The inner with the middle is again horizontal. And finally, the smartphone is fixed to the inner ring motionless.
To have where to skip the axis, you have to drill plywood strictly parallel to the surface. This is not an easy task, but after some training everything will work out. You can, of course, not train, but come up with suitable loops for the axles of metal or the same plywood, which can be placed on the planes of the rings.
Now let's see how the smartphone hangs on the inner ring. Here you can also do as you like, the master, as can be seen from the following two photos, applied the details from the Meccano-like constructor:
Further, the device is shown in various positions. If your smartphone has a budget TFT-display with a limited viewing angle, it is very convenient to get an angle that is optimal for watching video, for example, from the chair. Having unwound the rings, you can get an effect similar to Leslie, but this is not recommended - the improvised "plain bearings" will quickly wear out.
