The idea was born to make a mini fountain myself. The design of the fountain itself is a separate story, but this article will discuss how to make a pump for water circulation with your own hands. This topic is not new and has been described on the Internet more than once. I am just showing my implementation of this design. If anyone is too lazy to do it, then such pumps are sold on Aliexpress for around 400 rubles (price as of February 2016).
So let's get started. A bottle of nasal drops was used as a body. For those who are interested, I will write down the dimensions of some parts. So, the inner diameter of the bubble is 26.6 mm, depth 20 mm. A hole slightly larger than the diameter of the motor shaft is drilled in it on the back side, and a hole on the side for water outlet (4 mm in diameter). A tube is attached to it first with superglue and then with hot glue, through which the water will subsequently rise to the top of the fountain. Its diameter is 5 mm.
We also need a front cover. I drilled a 7 mm hole in the center. The entire body is ready.
A hole for the shaft is drilled in the base. The diameter of the base, you understand, should be smaller than the diameter of the body. I have about 25 mm. In fact, it is not needed at all and is used only for strength. The blades themselves can be seen in the photo. Made from the same box and cut to the diameter of the base. I glued everything together with superglue.
The engine will rotate the impeller. It was most likely taken out of some kind of toy. I don’t know its parameters, so I didn’t raise the voltage above 5 V. The main thing is that the engine is “faster”.
I tried another with a speed of 2500 rpm, so it raised the water column very low. Next you need to assemble everything and seal it well.
And now the tests. With a power supply of 3 V, the current consumption is 0.3 A in load mode (that is, immersed in water), at 5 V - 0.5 A. The height of the rise of the water column at 3 V is 45 cm (rounded down). In this mode, I left it in the water for an hour.
Passed the test fine. How long will it last? good question, which only time can answer. When powered by 5 volts, the water rises to a height of 80 cm. All this can be seen in the video.
Video
Separately regarding the noise. On land you can hear it quite well. Under water at 3 V in complete silence, the noise of the pump can be heard quite a bit. You can't hear him at all over the rushing water. So we can conclude that it is quite suitable for a fountain, and for others as well. I was with you SssaHeKkk.
Discuss the article HOW TO MAKE A PUMP FROM A MOTOR
Make something useful out of useless children's toys or household appliances no problem for a master dreamer. And it's good that many electrical devices become obsolete and break down. It makes no sense to send such things for repair - it’s easier to buy something new. And true “homemade people” are just waiting for this. They immediately have a whole bunch of ideas that require immediate implementation.
Second life of children's toys
There are times when a self-propelled toy breaks into pieces. Probably, in order to calm the child down, you urgently need to buy a new one? Not at all necessary. You just need to start the family process creative thinking. And to do this, remove the remaining usable parts from the broken car along with the motor. Then collect all the toys in the house and choose the one that can be brought to life again. Probably, here you will need school knowledge in physics, chemistry and electrical engineering.
Repair of an old helicopter
Suddenly an old forgotten helicopter with an unusable engine and broken blades, which had long been lying on the mezzanine, caught my eye. He apparently waiting for my finest hour and now with pleasure showed off the blue and white sides with the half-erased inscription “USSR-0098”.
Such things must be handled carefully. The old man doesn't like fuss. You will have to carefully remove the remains of the large main screw by unscrewing several small screws. To get into the engine compartment, you need to remove the plastic battery box from below. The engine is held on by three bolts and, as expected, has two wires “plus” and “minus”, which are connected through a chip block to the power switch. All this must be carefully unsoldered and unscrewed.
Having pulled the engine out to a white light, you need to inspect it and compare it with the motor from the car. The fact is that to create lift, 250 -270 rpm is enough. and power 1 - 2 watts. The difference in engine characteristics turned out to be small. Then you can safely install a fresh engine on the helicopter. And then go to the model shop for a brand new main rotor. When everything is ready, the repaired rotorcraft is tested in the presence of the entire creative family.
Modern children's helicopter models are repaired using the same scheme. Only now they are radio-controlled, and therefore you will have to fork out money for a control panel, on which the rotor speed and the speed of the helicopter depend.
New engine for toy car
In order to make a small children's car, you need: wheels, the car body itself, wires, a control panel, various electronic boards and a motor. If you have all this goodness, they begin to create a model. There is no need to look for the engine, since it is already there. The car body itself can be make it yourself made of wood or plastic and decorated to your taste. It’s good for those craftsmen who have a small 3D printer in their home that can build any shape of model.
Often the machine is made quite simply. They take a long-abandoned small children's car with wheels, disassemble it down to the screw and try to automate it using a ready-made motor. The following are used: glue, electrical tape, small gears from watches, gearboxes from old models and much more. And people for whom such fun has become a real hobby often achieve great success in homemade products from a motor.
When several new models of children's cars have been made and tested, all that remains is to do something generally useful. It is necessary to design a fan that would freshen the air and inspire new ideas. For this you need just a few items that are at hand. Namely:
- a motor from a children's toy (you can't go anywhere without it);
- CD discs, 6-7 pieces;
- plastic bottle cap;
- cardboard tube approximately 10 cm high and 3 - 4 cm in diameter;
- switch;
- glue.
Manufacturing begins by cutting the disk into 8 equal parts from the edge to the center, not reaching approximately 1.5 cm from the hole. Then the resulting sections must be turned with one edge outward to form blades. The manufactured disk is placed on a plug, inside of which a hole is made for mounting on the motor.
Now they are making the leg and stand. Cardboard tube It can easily pass for a leg. Wires and batteries will be hidden inside it. The remaining few disks can serve as an excellent stand. All this is well glued and painted in different shades. The fan is ready for operation.
Motorized ship
In order for the child not to hang out at the computer for days, he needs to be gradually accustomed to making various and interesting things that he can make with his own hands. Spring is coming, the streams will run, and you will need a small boat that will symbolize the coming long-awaited warmth.
Necessary materials The child will find it in his room. Here you need:
- AA batteries 3 pieces;
- polystyrene foam, electrical tape, glue;
- motor from a CD drive or toy;
- plastic cover from a lemonade bottle;
- two pieces of plastic and iron washers.
The first step is to make a propeller. Slots for the blades are prepared in the cork. Flat ice cream sticks are the finished blades of the future boat. Then a hole is made in the plug to fit this screw onto the motor. All this is well glued. The power plant is ready.
Next, the shape of the ship is cut out of the foam. The front part of the boat is made triangular; a place is prepared at the stern for propeller with a motor, and in the middle you need a recess for batteries. Everything is connected and glued. They carry out tests in the bathroom and look forward to the first spring puddles.
Glider car
This is the most exciting toy created and tested by a child. On the ground, such a machine moves on wheels, and on the water on a special boat. It is made in 2 - 3 hours.
Necessary materials:
They are making a power plant. It is an engine with a propeller. The blades are cut using the neck of the bottle.
It should look like a rose. You can see from the photo that it is then screwed onto a plug attached to the motor.
Then they make the chassis. To do this, use a skewer. They put plugs on it that serve as wheels. They attach everything to a square bottle, inside of which the batteries are placed. Connect with wires according to electrical diagram. The glider is ready. If desired, you can replace the plastic propeller with a more rigid one. Then the driving performance of such a car will be appreciated not only by the designer himself, but also by his friends.
Crawling robot
Manufacturing the robot takes only a few hours. It's not quite the robot people imagine. He does not walk, does not swim, but crawls chaotically smooth surface. This effect is created due to the unbalanced rotation of the motor rotor. For real cars this leads to a tragic accident, but here it only causes a smile.
So, to create a robot you need a motor and a battery. A small oblong piece of foam plastic or foam cardboard is placed on the engine axis and glued. This serves as a destabilizer. To the very tip of it attach a decorative light element.
A battery is installed on top of the motor and covered with various interesting details. They make his legs out of toothbrushes, his eyes out of balls, decorate him with colored wire or paper clips, and so on. When turned on, the engine vibrates significantly, which causes the toy to crawl chaotically.
Other ideas
In addition to all of the above, motors are used in homemade products such as mini drills and drills. Such devices do not require unnecessary parts. They have one task - to rotate the fixed drill.
To do this, select a collet or regular chuck on the motor axis that will clamp a small drill. Then solder the wires from the engine to the batteries through the switch. When the assembled device has successfully worked, it is placed in an antiperspirant case or some other case that is most suitable for a motor with batteries. This whole little device fits in the palm of your hand. The switch is always located under the thumb.
Such devices are necessary for radio amateurs for drilling holes V printed circuit boards. They can also be used by cabinetmakers who engage in fine volumetric wood carving. Only instead of a drill, they insert a finger micro-mill for sampling and grinding hard-to-reach places.
As you can see, with a little imagination and diligence, a child, with the help of his parents, can create truly original toys and other useful things.
Every day creating something with your own hands is becoming more and more popular. So why not create a special thing when everything is conducive to it? While women are diligently engaged in embroidery, sewing, knitting, quilling, men can only tinker, repair, and improve.
What to make from a motor?
Some parts of equipment that is broken and unsuitable for further use can be used at home. Quite often, men have the question of what can be made from a motor. In fact, there are a lot of options, the main thing is patience, the ability to work with technology and imagination.
As one option, you can make an excellent fan from a motor. People also make cars, helicopters and other interesting things from this part. Everything you need for full-fledged work(especially for beginners) - these are special electronic circuits and radio spare parts. Of course, you cannot do this without self-confidence and patience. It’s not a fact that everything will work out the first time, but if you try, the result will be for a long time please the master.
Helicopter from a motor
Having decided what can be made from a motor, it is worth thinking about how this thing is created. Stores sell special diagrams and spare parts that will help you cope with this difficult task and sort out the details. Sometimes you can’t even wrap your head around it, from a motor, but in reality everything is very simple, you just need to pay due attention to this matter.
So, to make a solid helicopter, you need to stock up the following materials: models with drawings, tools, motor, glue, power supply and control panel. If the case is already ready, then all that remains is to place the motor in it and connect it to the control panel. After this, you need to try to start the helicopter, and then it will become clear whether it is ready for use or has some problems that need to be fixed. If you have any difficulties connecting the wires, it is better to contact knowledgeable person, otherwise the parts may be damaged.
Men are often interested in what can be made from a motor, other than a helicopter. Let's consider another option.
A car made from a motor
Making a car from a motor is very simple. To do this, you need circuits and boards, which are sold in special stores. After purchasing everything you need, you can get down to business. There are two options for making a machine: you can make the body yourself or buy a ready-made one, which will make the master’s work easier. By purchasing a set, a person receives car parts, wheels, wiring, spare parts, a control panel and the motor itself (if there is none). It is worth noting that this will cost more than buying a regular ready-made machine, but you can also get great pleasure from the process itself.
Thus, it is completely obvious how to make a car out of a motor - you just need to purchase a ready-made housing and place the main part of the car there. Don’t forget about the control panel, which needs to be properly connected to the toy. As a result, the person will receive homemade typewriter, which will be cooler than any store-bought one. In addition, it can be improved, repainted and decorated as your heart desires.
In addition to all of the above, the beauty of making a car from a motor is that the child will certainly appreciate all the efforts of the parent, after which he will be immensely happy. You can build a miracle car together with your children. This is a very entertaining and interesting activity. Let's look at what else can be made from a motor.
Fan
Do-it-yourselfers (that’s what some men call themselves) are constantly trying to absorb as much new information as possible in order to make something new. It is not at all surprising that they are interested in things from the motor. To successfully carry out this operation, you will need the main structural part, a battery, a sleeve, a bulb and two old blanks.
First, blanks are used (cut along the radius), then the blades must be bent carefully using fire. For the next stage of work, a champagne cork is perfect, which needs to be pulled onto the axis of the motor. After this, you need to attach the blades to it and build a stand for the fan. The motor and all other parts will be glued to the latter. So light and interesting way make a fan.
Conclusion
So it's clear that you can make a lot of amazing things out of a motor. The main thing is desire and patience. In addition, you should not be distrustful of fantasy and intuition. No need to be afraid of ruining the product! We advise beginners to use old unnecessary things (as in the case of a fan). Experiment, you will succeed!
The need for a miniature tool exists where a person is engaged in the manufacture of souvenirs, models of ships and aircraft, small technical units and parts.
Miniaturization comes in two ways. The first option involves the production of only miniature tools - disks, cutters, etc. The second option involves the production grinding tool based on miniature electric motors.
First option - Using a drill + (Video)
The first option has a simpler solution. Let's say we need to make a miniature grinding wheel, which will be installed in a drill or screwdriver. To do this we can take a broken disk. Draw a circle on it using a caliper required sizes. Then we cut out the future miniature disk along the drawn circle. In its center we drill a hole into which we insert a bolt with a diameter of 6 mm. We put the washer on the bottom and tighten it with a nut.
The bolt will be the axis of rotation of the disk. We insert it into the chuck of a drill or screwdriver and clamp it. With this tool you can cut materials in hard to reach places or having small sizes. Finished parts can be sanded.
It is easy to make a miniature cutter for cutting small parts made of plastic or wood. To do this, take an ordinary tin stopper from glass bottle. In the center of it we make a hole for installing the axle. The same bolt with a diameter of 6 mm can serve as an axis. Align the edges of the cork and cut out the teeth. It is advisable to make minimal markings.
Such a cutter, loaded into a drill or screwdriver, can easily cut small wooden planks, for example, for modeling. Plastics also lend themselves to this simple tool.
Second option - Self-assembly + (2 videos)
If the task is to make a miniature instrument with your own hands, then you must initially select an electric drive. A motor from various devices- a printer, an old cassette recorder or from an ordinary children's electrified toy.
Depending on the power of the electric motor, you can build a mini grinder in two directions. The first direction is to use a network power source. For example, from old mobile phone. The second direction provides for a completely autonomous model consisting of a motor that will be powered by batteries or accumulators.
The difference between the two directions is in the design of the case. In the first case, space will only be required for the electric motor, and in the second, a battery compartment will need to be installed. 
It is very convenient to use a segment for the body PVC pipes. If its diameter is slightly larger than the diameter of the electric motor, then electrical tape can be wound onto the motor. You can secure the engine using a glue gun.
As plugs, you can use plugs that are placed on PVC pipes during transportation and storage. It is necessary to make a hole in the front plug for the motor shaft, and in the rear plug for the power wire. The power connector and switch must be secured to the housing.
The ideal option would be to attach some kind of collet clamp to the shaft. This will allow you to use standard burs, drills and non-standard mini cutters and discs. If installing a collet clamp does not work, you can connect the shaft and cutting tool using a double contact from the electrical block. 
In a similar way, you can make a case for a mini angle grinder with autonomous power supply. Only after installing the engine in it, it is necessary to install the battery pack. The battery wires will be connected through a switch mounted on the case.
In both cases, on mini grinders you can use homemade instrument and standard industrial - burs and drills.
Different motors have different numbers of revolutions per volt and therefore are best matched to a specific toy or specific use - those that are suitable for use as a wheel motor will not be suitable for use with propeller and vice versa!
The first is a small motor with a diameter of 2.4 cm, it is great for use in homemade toys to rotate the wheels.

Hello! I came across your site while looking for the necessary mechanism to set our idea in motion! to what address Email We can send you our mock-up so they can look at it and tell us what kind of motor is needed to “revive individual parts of our model!” Thank you very much in advance!
