I am sure that you all love unusual, and sometimes incomprehensible things at first sight.
In this article, the author of the do-it-yourself YouTube channel will tell you how he made the lamp with a very unusual way to turn it on.
The author made this home-made using simple tools, literally “on his knee”. Repeating it is very easy!

Manufacturing process.
To begin with, the author needed to put markup on a piece of board. The dimensions of the future product are 390X220 mm.
Excess parts are trimmed with a hacksaw, and the corners are rounded off with a jigsaw.
The edges of the workpiece are slightly processed with a rasp or file, and sanded with sandpaper.
Only a small external part is required from this blank. Its author polishes using 20-H emery paper, designed for primary cleaning of materials.
Using a steel corner, the author transfers the profile of the outer contour, leaving 25 mm.
Next, you need to drill several holes for the entrance of the jigsaw blade. Then insert the canvas, tighten it with a screw, and saw through the entire perimeter along the marking.
The inner perimeter of the workpiece must be sanded with sandpaper.
As the basis, the author chose a small piece of wooden timber. He has already processed it.
I marked the locations for the power connector, limit switch, and chain. He chose the material with a screwdriver, although it is better to use a chisel.
Glues the base to the lamp frame, and fixes the gluing place with a self-tapping screw.
Now you need to drill two holes. One is required for the LED strip wire. The ball chain will pass through the second, it is important to check that it passes very freely.
The master covers the frame and the base of the product with varnish PF-283.
The author purchased a white LED strip, and checked its performance.
After the varnish had dried, he led the wire of the LED strip into the hole, and carefully glued it along the inner perimeter of the frame. Excess tape is cut off at a special mark on it.
Now you need to remove two balls from the old deodorants. Or use ping-pong balls. Wooden is too heavy and they will not fit.
A hole is drilled on one side of the ball, the edges are cleaned with a file. Inside the ball, on the opposite side of the hole, small scratches should be applied so that the magnet is firmly stuck to it.
The flat side of the cylindrical magnet is connected to the drill, its second side is abundantly lubricated with glue moment. Then the magnet is installed exactly opposite the hole. In the second ball, the magnet should be glued to the other pole.
In order not to wait until the glue hardens and to press the magnet to the ball harder, the author magnetizes the second magnet from the outside and pulls out the drill.
Here is a pair of balls turned out. Hold even through the thickness of the hand.
The hole is greased with glue, and a furniture dowel is inserted into it.
Here is a pair of tumble balls turned out. But they quickly magnetize arcs to a friend even from a great distance.
With the help of a dremel, the author cuts off the excess dowel, and polishes the surface.
If small voids have formed, then they can be smoothed with hot glue.
A hole is drilled in the center of the dowel along the diameter of the ball chain.
The chain is glued into the hole, and the balls can be left until the glue completely dries.
Wrapping the chain with foil (so as not to dye it), the ball is painted in golden color with spray paint.
First, the chain length for the upper ball is tried on, a blind hole is drilled in the center of the frame.
Then the chain is glued in and the suspension is ready.
The master cuts the second chain so that about 20 mm remains between the balls. It is also necessary to leave a small margin so that the chain almost reaches the bottom of the base. The surface of the last ball is cleaned with a file, and tinned.
The chain is passed into the hole intended for it, and soldered to the edge of the limit switch plate.
Now you need to consistently connect the contacts of the power connector, the normally open switch contacts, and the LED strip. It is important to observe the polarity.
Hot glue is applied to the bottom of the switch and it is installed in its place. At the same time, the edge of its plate should be opposite the hole with the chain.
In the same way, the power connector is fixed.
Drilling pilot holes in the base, the author closes electronics a suitable piece of plastic. Silicone feet are additionally glued to the bottom.
The author soldered a plug to the USB cable, and now this lamp can be powered by both a computer and other power sources with such a connector.
So, the lamp is ready. The power supply is connected.
The first ball in the off state is in the lower part of the frame, the chain is not visible. But if you lift it to the upper ball, then the chain will stretch, and the trailer will turn on the power! It is advisable to choose a limit switch that snaps as quietly as possible.
This kind of trick can be shown to your friends and acquaintances, surprising them, and talking about the wonders of anti-gravity. If you also hide the battery in the base, then the first time some will temporarily believe in "magic."
If you slightly take one of the balls to the side and release it sharply, then they will oscillate for some time.
Thanks to the author for the simple idea of a very mysterious and aesthetic lamp!
All good mood, good luck, and interesting ideas!
