DIY hair cutting at home with Xiaomi Enchen Boost wireless hair trimmer

Due to the prolonged Movement Control Order (MCO) period which has caused all the barber shops and hair salons to shutdown until further notice, I have bought a Xiaomi Enchen Boost wireless hair trimmer for DIY hair cutting at home.

Enchen is a startup company in ChongQing (重庆), China that has successfully crowd-funded their hygiene care products in Xiaomi Youpin (小米有品) platform. They have several models of wireless hair trimmer product, with the name of Boost, Hummingbird, Sharp3, etc. and I found the Boost model is easier to use and more suitable for novice users.

At the price of around RM50, the package comes with:
  • The electronic hair trimmer with built-in rechargeable battery
  • Cleaning brush
  • USB type-C charging cable
  • A small bottle of lubricating oil
  • 2 stainless steel hair cutting scissors
  • Plastic comb
  • Barber apron
  • User manual in Chinese language
There are sellers selling this Xiaomi Enchen Boost hair trimmer at a slightly cheaper price, but without the scissors, comb and apron.

Before using the hair trimmer, its battery needs to be recharged, and its cutting blade needs to be lubricated with the lubricating oil supplied in the package.

The package does not come with a charger. You will need to use your own wall charger or computer USB port to charge the hair trimmer. When charging, one of its LED will blink slowly, with "breathing" effect. After it is fully charged, the LED light will stop "breathing" and become continuously on.

The hair trimmer can be used while connected to its charging USB cable. Normally, it is used wirelessly after unplugged from the USB cable, so that you can move it freely without being tangled by the USB cable.

It takes about 60 minutes to reach 90% charge, and another 30 minutes to be fully charged. At 90% charged state, it can be used for 80 minutes. When fully charged, it can be used for 90 minutes.

The one button at the front of the hair trimmer functions to turn it on/off, as well as to toggle its normal/turbo speed. You can toggle into turbo cutting speed by turning it on with a long press instead of short press.

Its motor is pretty quiet without producing much noise. At normal speed, the motor rotates at 4,500 rpm and at turbo speed, 5,800 rpm. It is strong enough to even cut down fine copper wires, as shown below.

The Enchen Boost hair trimmer can be easily adjusted to trim down the hair from 3 mm to 21 mm at a slide to its back button.

Note that the hair trimmer body is not water resistant, and should be avoided from contacting with excessive water. Its cutting blade can be removed and rinse with water for cleaning purpose.

You can use the comb and scissors to fine tune the hair slope for nicer look after the trimming.

This Xiaomi Enchen Boost wireless hair trimmer is very easy to use and value for money. With it, you can easily DIY your own hair cut, and also help your family members' hair cut, even without any prior hair cutting experience. It is suitable for hair cutting to people from infant to old age. Its low noise operation is generally more acceptable to infants and toddlers, so that they are more cooperative and emotionally calmer during the hair cut.

One thing to criticize is that it only comes with user manual in Chinese language. The user manual has clear instruction on how to operate the hair trimmer, cleaning and maintenance, and also some fault troubleshooting steps. It would be much better if English is included in the user manual.

You might have heard about FOMO, the acronym for Fear Of Missing Out. It is a psychological need of a person in society, particularly in social media. It is a common term nowadays used in advertising and marketing, applied in strategies and tactics to influence customer behaviour.

Other than FOMO, there are many other related acronyms spun off to describe a person's state of mind in the real-world and/or virtual community. Some of them have also become sales and marketing terms.

You can see these terms in social media hashtags.

FOMO = Fear Of Missing Out, or fear to be left behind. For example, when your friend posted something in the social media, and many friends reacted on it. You feel FOMO if don't follow suit.

FOBO = Fear Of Better Options. There is another one: Fear Of Being Outcompeted. This is commonly seen in a job interview. The employer is FOBO (fear of better options), the candidate is also FOBO (fear of being outcompeted).

YOLO = You Only Live Once. This is a trait of positive personality to live the fullest. It is also a common advertising term.

MOMO = Mystery Of Missing Out. This is a higher level of anxiety than FOMO. For example, when you post something in the social media and anticipate your friends to react, but you get very little reaction, you might fall into MOMO state.

FOMOMO = Fear Of the Mystery Of Missing Out. You are fear to post something, because you are fear of MOMO.

FOJI = Fear Of Joining In. This is another term of FOMOMO. Nowadays FOJI is a more commonly used term than FOMOMO.

BROMO = Bros protecting you from Missing Out. This is an act of solidarity from your friends to avoid you feel FOMO.

SLOMO = Slow to Missing Out. When something has happened in your social network while you are offline or sleeping, and you realize later...

JOMO = Joy Of Missing Out. This is the opposite of FOMO. You feel okay or even happier to be offline.

15 habits of genuinely intelligent people

I've just read an article written by Jessica Wildfire about 15 habits of genuinely intelligent people.

To summarize, the mentioned 15 habits are:

  • They don’t talk about how smart they are.
  • They learn best by imitation.
  • They try to figure things out themselves.
  • They are always hunting for knowledge.
  • They don’t brag about what they know.
  • They connect the dots.
  • They are OK with cognitive dissonance.
  • They ask a lot of questions.
  • They abstract from their experiences.
  • They seek out puzzles and paradoxes.
  • They don’t get hung up on crumbs.
  • They move slow, until they hit warp speed.
  • They have no problem with failure.
  • They don’t try to sound smart.
  • They don’t always use big words.
If there is one habit that oversees all the others, it will be: empathy. Intelligent people try to think from lots of different viewpoints. They try to understand how their actions affect everyone - not just themselves, or the handful of people they care about or agree with.

The differences between Huawei Watch GT 2 and Huawei Watch GT 2e

Huawei has recently launched the Huawei Watch GT 2e which priced about 30% cheaper than the flagship Huawei Watch GT 2.

While Huawei Watch GT 2 comes in 2 case size variants of 46mm and 42mm, the Huawei Watch GT 2e only has one case size, which is 46mm.

There are a lot of similarities in the specifications between Huawei Watch GT 2 and Huawei Watch GT 2e. Many people has been asking, beside the obvious different in price tag, what are the differences between both of them?

After some fact finding, I have concluded that the Huawei Watch GT 2e is a model with features and functions in-between the 46mm and 42mm variants of Huawei Watch GT 2.

The main differences of Huawei Watch GT 2e from Huawei Watch GT 2 42mm
  • The case size of Huawei Watch GT 2e is 46mm which is larger than 42mm.
  • Its battery life of about 14 days is longer than the 42mm's 7 days.

The main differences of Huawei Watch GT 2e from Huawei Watch GT 2 46mm
  • It has a smaller RAM size of 16MB, compared with the 32MB RAM of Huawei Watch GT 2 46mm.
  • It does not have a microphone and unable to make phone calls.
  • It does not have a speaker and unable to play music directly or listen to phone calls.
As such, the Huawei Watch GT 2e can be seen as a scale-up version of Huawei Watch GT 2 42mm but a scale-down version of Huawei Watch GT 2 46mm, with a new attractive price tag. This can be summarized in the table below.

By the way, since the Huawei Watch GT 2e is newer, it comes with a firmware with more features, such as the SpO2 blood oxygen saturation measurement. The sports mode also increased from 15 to 100, with sport activity auto-detect capability.

Anyhow, these software features improvements are anticipated to be made available to the Huawei Watch GT 2 as well through new firmware update. For example, right now, the SpO2 measurement is now already available in Huawei Watch GT 2 after firmware update to version and above.

Using Android phone's camera as webcam for PC and Mac with Iruin

Not long ago, I wrote about DroidCam which can turn the camera on your Android smartphone into webcam for your Windows or Linux computer, to be used in Skype, Zoom, and other applications that utilize a webcam.

The main limitation of DroidCam is that, right now, it does not work with Apple's product. You cannot use it to capture and stream video from iPhone or iPad, nor use it as webcam in iMac or MacBook.

Not to worry, because there are alternatives to DroidCam that can also work with Apple's product, such as Iruin.

Similar to DroidCam, in order to make use of the camera of your smartphone as webcam for your computer with Iruin, you will need to install the Iruin webcam app in your phone, and then install Iruin webcam software in your computer.
and then
Iruin is very easy and straightforward to use. It has a very clear-cut Settings page too.

It is simple, yet powerful. It's free version can support high resolution and even 4k video (3840 x 2160). I found its video brighter, clearer and finer than DroidCam too.

To use Iruin as your webcam, just select "Iruin Webcam" as your video camera source. Below is an example of how to set it in Zoom.

Buying guide for electronic dance mat for TV / computer

Nowadays, particularly during the Movement Control Order (MCO) period, a kind of electronic dance mat that works together with TV or computer has become a hot selling item in many e-commerce platforms.

This kind of electronic dance mat is a kind of portable floor blanket with electronic sensors underneath, so that it can become an input device to its dancing/gaming console box, using TV or computer screen as its interactive screen display.

It is ideal for home aerobic exercise, and to have a fun interactive time with children.

Normally, the electronic dance mat system has 3 main functions:
  • Dancing with music by accurately stepping at the right region on the mat at the right timing, which could also include waving your hand at the right timing.
  • Aerobic exercise and yoga training by on-screen coaching.
  • Playing console games

Below are some of the key considerations when buying an electronic dance mat for your reference.

1. Dance mat for 2 persons

There are 2 variants of this kind of dance mat. The square single person mat, which is cheaper, and the rectangular 2 persons mat, which is double the size of the single person one.

Unless you are living alone and always using the dance mat alone, otherwise you won't be regret buying the 2 persons mat, so that you can dance together in 2 persons, and playing interactive console games in 2 persons mode.

2. PU surface material

Normally the dance mat surface material is made of either PVC or PU. PVC type is slightly cheaper, but less durable. The PU type is more robust and durable, and provides better touch with the foot. It is also water resistance, and easier to clean.

The PVC type comes with varies thickness, some can be as thick as 30mm to 50mm, depends on the filler foam inside it. The PU type is normally as thick as the thin PVC type without extra thickness. Anyhow, you can always achieve the same thickness effect by laying a layer of tatami foam tiles underneath the PU dance mat. The cost for tatami foam tiles as shown below is much cheaper too.

3. HDMI connection

Older version of the dance mat console box connects to the TV by composite RCA cables. Newer version connects to the TV by HDMI cable.

Unless your TV has limited number of HDMI ports, it is better to choose the dance mat which uses HDMI connection rather than composite RCA connection, as HDMI supports higher screen resolution.

4. Wireless connection

Older version of the dance mat is integrated with its console box. The distance between the dance mat and your TV will then be restricted by the length of the connecting cable.

Newer version of the dance mat connects wirelessly to a separate console box, which in turn connects to the TV with HDMI or RCA cable. In the way, you can place the dance mat anywhere within the wireless communication distance. The dance mat will need to operate using batteries.

5. Wireless hand controllers

Hand controller is another input device beside the dance mat. Beside buttons, it also has a gyroscope sensor inside to detect hand movement.

If your dance mat is for single person, your package will come with one hand controller; if your dance mat is for 2 persons, your package will come with two hand controllers.

There are 2 types of hand controller. The older version is wired to the console box, and the newer version is wireless. You should get the wireless one which provides you with freedom of movement.

Certain dance mat packages don't come with any hand controller. They are either having a console box with camera that can capture your body movement, eliminating the need of using gyroscope in the hand controller, or the package reduced the price by not supplying with the hand controller.

Hand controller is quite essential which playing console games. Without the hand controller, the games could become very difficult to play, less fun, or even totally unplayable.

6. SD-card external storage

SD-card makes it possible to add more games and music to the dance mat system.

More intelligent dance mats can automatically generate dance steps by analyzing on the new MP3 files you store in the SD-card, while other less intelligent dance mats (usually cheaper) will always generate the same set of dance steps regardless what MP3 file you store in the SD-card.

Some cheaper version of dance mat system is without SD-card slot, and you are confined with the games and dancing music provided in the internal storage of the system. You are not able to add more on top of the existing.

7. Language

Most of this kind of dance mat are made in China. Most of their system only come in Chinese language. Some of them have English user interface. If you need English, make sure you choose the correct one, which needs to be explicitly indicate it has English user interface.

Below are some of the optional features and functions that are nice to have, which you can consider as well. Usually these additional features and functions will raise up the price tag of the dance mat accordingly.

a. Dancing stage light

Some dance mat comes with a crystal ball dancing stage light, making it more fun to dance on it.

b. LED guiding lights

Some PU type dance mat comes with LED lights to guide you to step on the right place when dancing on it. Those dance mat with LED lights will consume more number of batteries.

c. Augmented reality

Some dance mat system with camera can make yourself appear in your TV screen as a character. You can then dance interactively together with animated character(s) in the TV. It is also more fun playing games in augmented reality.

d. Connect to computer

Most newer version of dance mat's console box is able to connect to your computer by using a USB cable.

After installing the correct device driver, your computer will then be able to recognize the dance mat and its hand controllers as input devices.

The dance program, exercise coaching program and games are of separate set from those in the console box, and need to be installed in your computer.

There are also third party dance program such as StepMania which you can download and install in your computer to work with the dance mat.

This feature is good to have, because your computer screen is usually much smaller than your TV, unless you use a projector screen. Normally, people will just use the dance mat with TV, and seldom with computer.
