2016, Miband would stand tall as usual

Smart Wearable industry begins from activity trackers. Activity trackers has been the most popular and most successful smart hardware in a few years.

Industrial Pattern

Technology and business model of smart wearable company in Europe and America slowing down.

Take an example, some new bracelet from America smart wearable company, dull spots near the sprue of the USB. That’s surprised us. A company who can’t control the product hardware details,It’s hard to bring the new idea in the hardware.
This is not the only example; this is the typical question of most of traditional large hardware company.
Most of traditional large hardware companies need to take a month to fulfill a hardware project which is only taken 2 weeks to finish for Chinese companies, because they are far away from the central of manufacturing and supply chain which cause the difficulty about verbal communication, culture, geographical distance, and jet lag.
Smart wearable involves the availability about near skin material, and 24 hours wearing. Hardware-engineering team need to try a lot to find the most preferred plan of the innovation in the hardware tech and the material, craft. If the geography question cause the too heavy time cost, or lower the engineering efficiency, and the innovation cycle will be draw out.
It’s fatal to smart wearable industry which develops very fast.
Most important is that lots of Chinese Internet companies invest lots of money and human resources into smart hardware. This makes Chinese Startup companies do better than Europe or America hardware companies.

Why can Huami company won this battle?

Miband is the first smart wearable of Huami. It has all functions of mainstream product, and also has some particular functions, like unlock the phone without passwords. Most grateful is that the endurance is longer than 30 days.

Most important is that Huami spend 8 months finishing the large projects from development to large scale production.

Huami ranks first of Chinese market, third of the global market depend on the Xiaomi brand, supply chain, internet traffic, E-business and etc.

There are many smart wearable startup companies like Huami. Most of them are making efforts to practice seven words: Focus, Extreme, Word of mouth, fast which was summarized by Leijun, founder of Xiaomi. This is what we trying to do now.

DIY Quadcopter: Build Your Own Quadcopter III

Last time we talked about the Frame (house all the other components), Motors (flying power), Propellers (flying power maker). These components are relatively simple and it is easy to understand how they work and what they will do to let the quadcopter fly. This time we are going to talk about some complex components. But first, let’s start with something simple.

Battery

Since we need something light to be our quad’s component, the Li-Po battery becomes our only choice. Maybe some people would say NIMH is cheaper, but sadly, the NIMH does not have the right weight. The other reason we choose LIPO is because its current ratings meet our requirement.

Next we need to know something about the battery voltage. Normally LIPO battery can be found in single cell which is 3.7V. Usually we group them to 11.1V, which means 3PCS pack as 1 pack. We can DIY different battery voltage by the same way.

As for the battery capacity, you need to do some calculations on:

  • Ÿ   How much power your motors will draw?
  • Ÿ   Decide how long flight time you want?
  • Ÿ   How much influence the battery weight should have on the total weight?

A good rule of thumb is that you with four EPP1045 propellers and four Kv=1000 rated motor will get the number of minutes of full throttle flight time as the same number of amp-hours in your battery capacity. This means that if you have a 4000mAh battery, you will get around 4 minutes of full throttle flight time though with a 1KG total weight you will get around 16 minutes of hover.

The battery discharge rate is also an important factor we should notice, which also be called C-value. The C-value together with the battery capacity indicates how much current can be drawn from the battery.

Another important factor is the discharge rate which is specified by the C-value. The C-value together with the battery capacity indicates how much current can be drawn from the battery.

Maximum current that can be sourced can be calculated as: MaxCurrent = DischargeRate x Capacity

For example if there is a battery that has a discharge rate of 30C and a capacity of 2000 mAh. With this battery you will be able to source a maximum of 30Cx2000mAh = 60A. So in this case you should make sure that the total amount of current drawn by your motors won’t exceed 60A.

ESC – Electronic Speed Controller

The brushless motors are multi-phased, normally 3 phases, so direct supply of DC power will not turn the motors on. That’s where the Electronic Speed Controllers (ESC) comes into play. The ESC generating three high frequency signals (with different but controllable phases) continually to keep the motor turning. The ESC is also able to source a lot of current as the motors can draw a lot of power.

The ESC is an inexpensive motor controller board that has a battery input and a three phase output for the motor. Each ESC is controlled independently by a PPM signal (similar to PWM). The frequency of the signals also vary a lot, but for a Quadcopter it is recommended the controller should support high enough frequency signal, so the motor speeds can be adjusted quick enough for optimal stability (i.e. at least 200 Hz or even better 300 Hz PPM signal). ESC can also be controlled through I2C but these controllers are much more expensive.

When selecting a suitable ESC, the most important factor is the source current. You should always choose an ESC with at least 10 A or more in sourcing current as what your motor will require. Second most important factor is the programming facilities, which means in some ESC you are allowed to use different signals frequency range other than only between 1 ms to 2 ms range, but you could change it to whatever you need. This is especially useful for custom controller board.

DIY Quadcopter: Build Your Own Quadcopter II

In our last article we just introduced 3 different ways to build a personal quadcopter. It is important to decide where you should start your road of DIY quadcopter according to your own situation. However, no matter which way you choose, it is necessary to understand these basic parts of a quadcopter or multicopter.

Last time we just have a simple look of these basic parts, to know what they usually look like. This time let’s talked them in details.

Frame

Every quadcopter or other multirotor aircraft needs a frame to house all the other components. The Frame should be rigid, and be able to minimize the vibrations coming from the motors. So what you need to consider is size, weight and material.

A quadCopter frame consists of two to three parts which don’t necessarily have to be of the same material:

  • Ÿ   The center plate where the electronics are mounted
  • Ÿ   Four arms mounted to the center plate
  • Ÿ   Four motor brackets connecting the motors to the end of the arms

Materials you should consider:

  • Ÿ   Carbon Fiber
  • Ÿ   Aluminum
  • Ÿ   Wood, such as Plywood or MDF (Medium-density fiberboard)

Although it is expensive, we highly recommend carbon fiber here because of it is the most rigid and vibration absorbent out of the three materials. The other two materials have their own disadvantage, which is not good for a quadcopter.

As for arm length, the term “motor-to-motor distance” is sometimes used, meaning the distance between the center of one motor to that of another motor of the same arm in the QuadCopter terminology.

The motor to motor distance usually depends on the diameter of the propellers. To make you have enough space between the propellers and they don’t get caught by each other.

Brushless Motors

The reason we mentioned about brushless motors here is because this kind of motor is most effective motors for DIY Quadcopter. Generally brushless motors spin in much higher speed and use less power at the same speed than DC motors. Also brushless motors don’t lose power in the brush-transition like the DC motors do, so it’s more energy efficient.

Brushless motors come in many different varieties, where the size and the current consumption differ. When selecting your brushless motor you should take care of the weight, the size, which kind of propeller you are going to use, so everything matches up with the current consumption. When looking for the brushless motors you need to notice the specifications, especially the “KV-rating“.

The KV-rating indicates how many RPMs (Revolutions per minute) the motor will do if provided with x-number of volts. The RPMs can be calculated in this way: RPM=Kv*U An easy way to calculate rating of motor you need.

Make sure you buy the counter-rotating to counteract the torque effect of the props.

Propellers

On each of the brushless motors there are mounted a propeller.

You might not have noticed this on the pictures, but the 4 propellers are actually not identical. You will see that the front and the back propellers are tilted to the right, while the left and right propellers are tilted to the left.

Like we mentioned before, 2 rotors rotates in the opposite directions to the other two to avoid body spinning. By making the propeller pairs spin in each direction, but also having opposite tilting, all of them will provide lifting thrust without spinning in the same direction. This makes it possible for the Quadcopter to stabilize the yaw rotation, which is the rotation around itself.

The propellers come in different diameters and pitches (tilting). You would have to decide which one to use according to your frame size, and when that decision is made you should choose your motors according to that

DIY Quadcopter: Build Your Own Quadcopter

Introduction

After a long time development of quadcopter technology, we can now enjoy many cheap quadcopters. Like Syma, WLtoys:

We can buy the READY TO FLY quadcopters online and we can fly them when we take them out of the box.

As a hobby, flying a quadcopter indeed brings us a lot of fun, however, when we tired of just flying them, what fun can we get from this hobby?

The answer is the topic today: We build a quadcopter ourselves. We decide what our quadcopter looks like and what functions they have.

There are three kinds of ways that we can build a quadcopter ourselves.

Kits

Kits means that you can buy a package that contains all the basic parts of a quadcopter, you don’t need to spend too much time on finding the parts. Also it is great for people who don’t have much time to understand which components will work well together.

The components in a kit are usually carefully matched and pre-soldered making them easier to build.

DIY

On the contrary, the DIY means you need to find all the quadcopter parts yourself. It will take more time and perhaps even appear to cost more initially. However, it will be much cheaper to replace a part since you have lots of choices and are not forced to buy a part made by the kit manufacturer.

Also, you can buy and configure any flight control board with whatever features you require. This gives you total flexibility of which features you need and want. It also allows you to change boards as your demands change. Here are the basic parts of DIY the quadcopter.

  • Frame

  • 4 Motors

  • 4 ESCs

  • 4 Props

  • 1 Flight Controller

  • 1 Lipo Battery

  • l  Transmitter and Receiver

  • Miscellaneous Parts (Wire, connectors, etc)

  • l  Battery Charger

The Third Situation

OK, maybe you don’t have the talent on rebuild a quadcopter or the mood to collect those quadcopter parts separately. There is also a choice for those guys: we can buy the quadcopter which provides DIY version. For example, the Walkera Runner 250 Series, which has one basic version and other three kinds of DIY versions.
