Electric skate: features and types of device, design, control

How to make an electric skate with your own hands

An electric skateboard is a modified and modernized skateboard that is powered by a small electric motor.
It’s convenient to use such a board – it’s compact, fast, and a pleasure to ride. Both children and adults can do this. The cost of a new electric skate today starts from 25,000 rubles, but you can make a moving board yourself. And this electric homemade product will be able to compete with the new skateboard of famous brands. If only you had the desire and some skill, you can make anything your own! electric skate

Disadvantages of Electric Skateboards

The main disadvantages of the devices described in the article include their cost. It must be said that it significantly exceeds the price of a traditional skateboard. If you focus on famous brands, then such a toy is oh so expensive and some fans of the drive can easily be scared off by the price tag. But it doesn’t matter, there are always cheaper options!

The electronic component takes up a very significant percentage of the cost of the device. If it fails, count on a significant amount of money to restore it or completely replace it. To avoid this kind of misunderstanding, handle the gadget with the utmost care, especially since it is not so difficult.

If you use the vehicle frequently, you will also have to charge the battery frequently. As a result, due to frequent discharge-charge cycles, the battery will exhaust its life very quickly.

Selection of materials

Making an electric skateboard is an inexpensive project that requires little financial investment. In essence, this is simply upgrading an old board or assembling a new one from familiar items: base, wheels, engine, etc.

You can choose any design for the future board. Externally, a skateboard with an engine is no different from conventional boards, but can reach a speed of 30 km/h and has reliable brakes, which sometimes come in handy.

It is important to pay special attention to the wheels of the product - they should be of medium hardness and large diameter, have plastic bushings that are ideal for mounting the wheels on the axle.

Wheels are also sold at skateboard parts stores.

General Description of Electric Skateboard

Visually, an electric skate is almost no different from a classic skateboard model without a motor. But the device still has its own distinctive features:

1. Dimensions. An electric skate weighs approximately 5 to 7 kg (depending on the type and model). Its wheels are more massive, which ensures smooth travel over uneven roads.
2. Has 1 motor or more. The power of the gadget and the maximum speed it can develop depend on this. If desired, you can turn off the motor and use the electric board as a non-motorized board.
3. Electric skateboards have lithium-ion batteries from which the device draws energy. It is used sparingly, so 1 charge can last for several tens of kilometers.
4. Charges from a standard 220 V socket using the included cable. Some models can be fully charged in a couple of hours.
5. The device is equipped with remote braking using a remote control. It also regulates the direction of movement and speed.
6. The motor is activated by pressing a button.

Platform

It is advisable to take a longboard as a platform - a long skateboard. It is more stable, and there is also more space on the longboard to accommodate electrical elements - the motor, etc.

If the project starts from scratch, the base is cut out of plywood or carbon fiber. The straighter the board, the better; it may not even have the usual bends. You just need to take into account that there is enough space for the electrical unit and immediately determine the location for its installation.

skate base

A board without wheels can be purchased at special sports stores.

But if the spare part is created independently, this gives room for imagination - the board can be given any shape - and saves the budget.

Motor and wheels

The interaction between the motor and wheels is carried out using gears. You can buy them in a special store, or you can use a regular bicycle chain for this.

A gear with 36 and 5 teeth is taken, which are connected through a belt (or chain). The shaft is modified with two M4 thread nuts. In the smaller gear, you need to drill a hole and fix the gear on the motor shaft.

wheels

The motor must be fixed close to the axis, and it is important to calculate everything so that the belt does not slip off the gear while moving.

The tension should be optimal.

fitting

Engine mount

The engine is mounted on the underside of the board using clamps and bolts. This could be an aluminum mount or any other. But in order for the electric motor to be safe while moving, it is advisable to build a durable housing that can withstand impacts.

This housing is made of mesh, so the motor will be ventilated.

strong mesh

Before placing all the motor elements in the housing, it is advisable to make a drawing on a scale of 1:1. Or simply lay out all the elements of the motor on paper comparable in size to the size of the box. Only then, when everyone has found their places, should they be placed “in reality”.

Inside the case, the controller is attached with double-sided tape. The wires must be in a free niche.

placement of elements

If you do without a housing, it is important to assemble the engine in the correct order:

1. Place the large roller on the wheel axle. Pin.
2. Place a small roller on the engine pulley.
3. Place a belt over both rollers.
4. Tighten the belt while moving the engine and secure it, leaving it taut.
5. Then position the battery - secure it closer to the center and the board.
6. Place the controller on the front side of the electric skateboard.

bringing out the controller
Skate is ready to be tested on the street! It may seem too heavy to perform some tricks, but this product is unique and made by hand.

If desired, such a skateboard can later be upgraded: change the motor, controller, etc.

DIY electric longboard. Mountainboard.

So, another, almost annual post about electric boards. This year we will talk about mountainboarding. I would like to point out right away that this mountain was made for riding on asphalt or what we call this word. No one will knead dirt on it.

This board is based on Trampa 685 BLACK. Great board. If you take it for the city, choose softer bushings (Dampa).

The pulley has 66 teeth per wheel, also from Trampa.

Price: about 44-46k rubles (depending on the exchange rate) for the whole board and pulleys with 66 teeth.

The brackets were found on one of the foreign forums. I was captivated by their compact appearance. They fit perfectly on the tracks.

The fruit of labor, tears, sweat and blood for three weeks.

In short, we smear, grind, smear, grind,... repeat until an acceptable result is achieved. In between, apply release agents. I used polyester resins, glass mat 300 and 450 for the mold, and T-11 fiberglass for the body itself.

As a result, we get a body with 6 segments, which bends perfectly along with the board.

Price: 6-7k rubles for materials (I took a lot and with a reserve). Plus a lot of rubles for the instrument.

Two 6368 150kv 2.3kW. Probably the main one is plus the minimum number of holes into which dust gets in. This gives me some hope for a longer lifespan compared to their more leaky counterparts.

Price: $120 for 2 motors

10S5P battery made from 18650 Samsung 30Q cells. Spot welding, connection between successive cells - flexible cable in silicone insulation. Estimated mileage 25-30km.

Price: about 14.5k rub

This year it's time to experiment. Just for fun, and in order not to inflate the budget at all, I decided to take a cheap Chinese esc for longboards with two motors and a remote control included.

Impressions about him are mixed. The disadvantages (compared to VESC) are a sharper start, lack of telemetry, lack of settings, strong heating. Pros: price, board charge indicator on the remote control, reverse from the remote control. This esc was purchased consciously, so strong heating is not an obvious disadvantage, because... In principle, putting it on such boards is a so-so idea. But I decided that if it survives an asphalt mountainboard, then life on regular boards will clearly be easier for this controller.

Is it possible to make a skateboard with a motor with your own hands?

A skateboard equipped with a motor is a modified and improved version of a skateboard. It operates using a small electric motor. This board is easy to use. It doesn't take up much space and goes fast. Prices for it start from 25,000 rubles.

More and more people are wondering whether it is possible to make an electric skateboard with their own hands. One craftsman has already assembled an electric skateboard on his own. Moreover, the invention can compete with purchased branded products. This is possible even with a relatively limited budget.

The inventor claims that his skateboard with an electric motor reaches speeds of up to 30 km/h, has brakes and a range of 10 km. The author had to buy most of the spare parts.

Types of electric skateboards

The division is based on power, the permissible weight of the rider, as well as the type of road surface suitable for a particular board.

Classification of electric boards according to the maximum permissible rider weight

Light: up to 85 kg

Medium: up to 100 kg

Heavy: up to 135 kg

Classification of electric skates according to the type of road surface for which they are intended

Urban: have narrower and smoother wheels, modest electric motor power and low weight.

Off-road: these devices have clearly defined treads, which allows you to move more efficiently on moderate off-road conditions. The power here is already higher when compared with urban variations, and the weight is also greater.

Classification of electric boards by power

Children's: power up to 150 W. Such devices can reach a maximum speed of up to 15 km/h.

Professional: power reaches 350 W.

Required tools and materials

Making a skateboard with a motor is an inexpensive project. A homemade product can consist of either an old board or be new. In the latter case, it includes a base, wheels, an engine and some other elements. The skate design can be anything you want. This will depend on personal preference. In appearance, an electric skateboard is not much different from simple boards.

To make a similar vehicle, you need to take care of the necessary tools and consumables for assembly:

• large wheels;
• driven sprocket and chain;
• batteries;
• plywood;
• bolts and nuts;
• motor;
• regulator for the engine;
• cable;
• charging controller;
• screwdrivers and wrenches;
• soldering iron;
• drill;
• Bulgarian, etc.

The author used a brushless motor for his homemade product. Thanks to the large wheels, the motorized skateboard easily overcomes uneven asphalt and dirt roads.

Step-by-step instructions for making an electric skateboard

There are a lot of step-by-step instructions on how to make an electric skateboard yourself. Below is one of them.

For a platform, the best choice would be a longboard, which is longer than conventional boards. It is quite stable. This board has more space for installing electrical parts.

Attaching the driven sprocket to the wheel is one of the most important steps. Such an element must be located strictly in the center of the wheel. Otherwise, the sprocket will often fall off and it will not be possible to tighten it. It is necessary to ensure reliable and correct fixation. There are different types of wheels. Therefore, sprockets are also attached in different ways.

The inventor preferred fixation using a special adapter cut from plywood. First you need to cut a disk of suitable diameter. It will be attached to the wheel. Then you need to drill 5 holes. They will be needed to secure the screws. Additionally, you need to make a hole in the center. The axis will pass through it. You will also need to drill 3 more holes for the screws that secure the sprocket. At the end you will need to widen the hole for the axle.

We need to figure out the electrical circuit. If the motor is brushless, then you need an ESC speed controller. It is necessary to determine the capacity of the power supplies and their type. The most preferred are lithium. To assemble electronics, you need to be patient and take care of heat shrinks.

The chain drive is necessary for engine torque. A belt is also suitable for similar purposes. However, it is important to get the star ratio right. This calculation depends on the characteristics of the electric motor. The higher the speed, the more you need to lower the sprockets, which you can buy or make yourself. It is easy to find such a spare part in scooters and other equipment.

The mounting plate ensures reliable fixation of the engine on the skateboard. This part is made of aluminum. Holes are made in the corner for fastening. You will need to make several brackets. They are needed to fix the motor on the plate. All assembly is carried out using nuts and bolts. The material will be aluminum corners and plates.

After installing the engine, the skateboard is almost ready. Then you need to connect the electronics. You also need to secure the batteries and controller. Controls should be installed in the most convenient location. At the end of the installation of the chain, unnecessary parts can be removed. It is worth trying to turn on the engine and make sure that the chain is properly secured. It shouldn't subside. The engine works properly if it creates the necessary traction for driving.

Riding an electric skateboard brings a lot of positive emotions. Moreover, now you can assemble it yourself thanks to various training videos and step-by-step guides. The main thing is not to forget about safety precautions when driving and wear a helmet.

⇡#Embrace – watches that save lives

Embrace is a project whose goal is not only to improve the quality of life of their owner. Smart watches are unlikely to save the life of an ordinary person, but the developed system helps control epilepsy attacks in people suffering from this disease. And for them Embrace will become an excellent companion in everyday life. However, we will try to look at this watch from the point of view of an ordinary user.

Embrace tracks your physical activity and stress levels. This information allows people suffering from this disease to be warned about possible epilepsy attacks. For the average user, such data will allow them to avoid overvoltage situations. All information received during the operation of the watch is systematized and analyzed, after which the user will be able to draw certain conclusions for himself and learn to relax and rest in time, without bringing stress to a critical level.

Embrace was developed primarily as a medical device, so it meets all medical standards. The watch can be linked with a smartphone and with other watches - due to this, a guardian or parent of a person with epilepsy will be able to help in time, thereby reducing the risk of dire consequences. Embrace warns not about the onset of an attack, but about its possibility, analyzing the body's vital signs. And this is really useful, because preventing a possible attack is much more important than simply warning about it. At the same time, the watch is sold under a promotion, within the framework of which, when you buy one copy for yourself, you automatically purchase a second one for a child with epilepsy who does not have the funds for Embrace.

Yet the Embrace campaign is not a charity. The watch itself is a fashion accessory, with a strap made from Italian leather and a choice of strap and case colours. The fastener on the bracelet is made using magnets. Embrace can either work as an analog clock or serve as a means of notifying events on your smartphone.

You can purchase Embrace either at retail through the official website or through the Indiegogo platform. You can support the campaign on Indiegogo for $189, receiving a watch and a gift for this, and another watch, as mentioned above, will go to a child with epilepsy. The gift includes, in particular, a subscription to the support service for 6 months. The service will process all information about your life activity and analyze it, displaying the results in a special application. The campaign has raised more than $500,000, so there should be no financial barriers to Embrace's exit. The watch will be delivered in December this year.

DIY electric skateboard

This article is for those who want a quick guide on how to build DIY electric skateboard on a relatively small budget that can compete with a new branded skateboard costing over $1,200. I built a skateboard that can reach speeds of about 30 km/h, has brakes and can travel 10 km. Below are videos and photos of my work. Below them will be a description of the parts and changes I would make if I were to make a skateboard like this again.

Please don't try to replicate this design because there is no guarantee it will work after some of the changes I made to it. This is just a prototype.

As when driving any type of transport, do not forget to wear a helmet. All this is dangerous! I am not responsible for any injuries or damages that you may receive. Be careful!

Benefits of Electric Skateboards

Any electric skateboard, except for high-power designs intended for off-road exploits, can be used as an ordinary skateboard. If the battery energy is exhausted, it becomes possible to calmly operate your lower limbs, while succeeding in high-speed movement.

Even if we take into account the electrification of skateboards, they still have not changed their dimensions - the same compactness as before. They can be easily carried in your hands or transported in a backpack. They will not cause any difficulties when traveling on public transport, unlike electric scooters and electric bicycles.

Particular attention should be paid to the control element of the electric skateboard—the remote control. A very original solution from the developers. The element does not interfere with the rider's high-speed travel, is small in size and can fit in one hand. The control buttons on it are scattered very conveniently, you always know where and what is. You can easily control speed modes, starting the electric motor and some other options.

Using the remote control, it is possible to control the electric skateboard from a distance without being on it. You can bring the skateboard closer to you or, on the contrary, drive it away, playing with it like a toy. Or you can just take one of your friends for a ride on it.

An electric board has quite a considerable amount of energy and can offer a decent top speed. According to these parameters, an electric skateboard holds the upper hand over hoverboards. Even if we take into account the maximum speed of movement, such skateboards can provide the rider with movement for an hour or even more - it all depends on the electric board model.

Many devices are equipped with front lighting technology using LEDs that consume little energy, but provide sufficient lighting power.
