DSC_0022

Few days ago, I have wonder my Nexus4 has going hotter and back has exapnded like pregnant. And I can sens it is cause of internal battery life has the end. So I unscrewed double screws on bottom of Nexus4. Open up back cover with plastic openning tools, then I can see sudden death battery.

If I has continue to charging this dead battery, it will blow and my Nexus4 may damaged. Dead battery is always prblem of all devices of has internal battery that si covered with plastic, metal or glass shelter.

Nexus4 fixed battery with adhesive tape like iPhone. You will be need something more safe tools like plastic scoop to remove battery from adhesives.

Replaced battery is need to be charged in fully overcharged in more times to reach 100% in power off. It is different with displaying on Android state bar. If you doing replacement like me, Just powered with charger and turn your phone down. Then wait for enough hours while battery display reach to 100%. Don’t unplug charger it just changed to 100%, you may need more hours for overcharged to reset battery chemical reaction.

 

A Simple review of Earmax ER610

e610_retail_box

It is arrived in waited for long days. They simply described headphone specification in upper side of paper box (I can’t read chinese, so I paraphrased) :

  • Model name: ER610
  • Supported Frequency: 20 ~ 18000 Hz
  • Impedance: 20 ohm.
  • Sensitivity : 125 dB
  • Cable length: 1.2 meters

Ok. I have continue to open a box.

e610_unboxing01

There’s anti-static protection, it was sealed. Need to tear vinyl.

e610_unboxing02

Retail box contains simply these:

  • A Mic-controller-LESS headphone. NO mic, NO Controller. (I’ve been ordered mic controller)
  • A plastic protective pouch.
  • Two pairs of spare different size of silicon tips ( small and large )
  • Impossible to readabled Chinese texted paper.

Shape of product

This headphone seems to made with aliminium alloy. Weight is really light, And contruction is not looks cheap, But some finishing is not clear like end point of metal cut of hole on each unit to cable protecting rubber. (see below picture)

e610_units

Nozzle of each unit applied protective metal mash. Silicon tips may compatibles with Apple IEM. Softness is not like Apple’s, more harder. It may problem for some people has weak ear skin tissue. (but I guess they don’t like IEMs, before worry about them)

e610_nozle_unit

Cable quality is not same with KZ series even it looks like similar. Much better quality in fitting and strength.

Hearing

First impact of hearing is just simple. It’s not like TWFK series of Knowles. Similar to UE Super.Fi 4. Feels like heavy and darker because of less high frequency as like below table.

freq_in_hertz_response

Definitely this is not for Hi-Fi reference audio as they written on the cover of box. Sound is too coarse, not optimized. Rather than better KZ-ED9 or KZ-ATE series to buy this in only tuned sound quality. Much far from HiFi reference.

Conclusion

This headphone contruction quality is good. But If you like to listen musics, don’t like to recommend this. I don’t believe it used dual BA of Knowles. Sound is too coarse like sands in wind. Middle range of frequency is inflated, but high is seems dead like zombie but it never be rised again.

Additional valuation

It’s not enough to believe used dual BA even try to listen in days. Expected crispy high frequency like others, but this has nothing like that. No advantage if you are finding featured in most of dual BA IEM.

Some tips for while delivery done in Ali-Express.

aliexpress_leftup_cutted  If you know, or want to buy something in Ali-Express of China, it will be better to read before you have do something.

Ali-Express mostly contolled by Ali-Baba and Ali-Express (Ali-Group) managing group. But you must remember sellers are not kind of employee of Ali. So Ali-Express made buyer protection system like doing “Open dispute”. But everything is depends on your decision.

Here I writing some good to remember buying something before use payment, and selecting good seller, or deal with seller.

buying_item_in_alie_01

They are Asian

First, they are mostly Asian, or Chinese. Some sellers are using really difficult-to-understanding English. You can check this on selling item description. You may something difficult to understand what they are written, even I am hard to understand also I am an Asian. So you may need read their description in focused.

Check Seller’s level

buying_item_in_alie_03 Every sellers are has their level like most of games. it starts with medal to medals, and upgrades to colorful jewels like above image. You may check how many people scored positive feedback. It’s easy but important.

 

 

 

 

Must read feedbacks

buying_item_in_alie_04buying_item_in_alie_02 This is really important. If you are buying over 10 USD, read feedback first. If feedbacks are within 10 or not 5 stars, don’t buy or consider it. Most of popular item feedbacks are written in Russian, then you may use Google translation web site, or use translate function of Android if you are using it.

Check delivery method

buying_item_in_alie_05-  You can choose delivery method in shipping selection on item page. And they are mostly using these delivery methods.

  • Chinese ordinary small packet, or Seller’s shipping method.
  • Chinese registered air mail
  • Hongkong air post
  • Singapore Post
  • Netherland Post
  • e-EMS or EMS
  • DHL
  • UPS

Here is some different conditions to selecting method of seller. Worst is “Chinese ordinary small packet” or “Seller’s shipping method”. It is mostly chosen by under value of 10 USD in free shipping. But it is really really really slow to your destination. It takes over a month in average in Asia. Other area may increased to 2 monthes. And a problem is they are using fake parcel codes in all numberic like 123123123. It shows fake delivery state in only China.

buying_item_in_alie_06

It doesn’t never tracked outside of China and even it is not real tracking method, just fake. You can’t predict when it arrived in your country. If you want your item quickly delivered in your destination? Choose “Chinese registered air mail” or more paid method.

And you may also remember, every Lithium-ion/polymer battery included goods are only deliver with “Singapore post” or “Netherland post”. It takes 2 or 3 weeks in normally, but sometimes over a month. Just you need keep calm and wait for long.

Dealing

buying_item_in_alie_08

You can ask anything to seller by clicking “Centact Seller” before buying, or after bought. And it is important to used in evidance of disputation and payback. Sometimes you can check delivery(shipping) method by message and pay more bucks to upgrade method. Because some sellers are not using “Chinese air post” even they are written in item page. You may need check this if you are now buying under value of 10 USD.

 Problems?

buying_item_in_alie_07

If you have any problem when you didn’t get ordered stuff over 2 monthes, or broken delivery. Don’t be panic. Just use “Open Dispute”. It is similar with normal conversation of “Messages”. But doing “Open dispute”, it automatically holds item delivery process. You must check shipping term remind days and it never arrived in your destination in promised shipping days, you must open dispute. Then you can claim your discontents on message area, and seller must be answered that in shortly. If not answered by seller, your bad stuff is automatically refund by Ali-Express buyer protection system. Don’t forget check delivery term.

Conclusion

Ali-Express is good online shopping method from goods of China. But you need understand what all sellers are not like your country. You need keep mind they are not like us, then make it order to safely delivered in your home in really low price.

ipTime, no more cheap power…

20150815_154721-01

ipTime router used cheap SMPS power source in many years ago and it all from China.

EFM is a company who selling ipTime series in South Korea. They are imports Zioncom products from China and only applying firmware in their hands.

Problem is belong to their China born power adaptors. It has too short life time in period 1 to 2 years.

My ipTime also met a presage of death by these features:

  • You cannot access WPS security, so client reports password is wrong.
  • Your WiFi continiusely disconnect.
  • It is going to unresponsed. You cannot access any internet even it connected.
  • All speeds are going too slow.

So I feel it is time to change power source. After doing that? It is fresh !

If you have problem like me, trash your adaptor and replace that to new one.

You don’t buy thing if don’t like lost your datas.

seagate logo

It’s very simple.

If your datas be alived until you lost yourself or human being has big war with atomic bombs, Don’t use seagate HDDs.

In case of me, a years ago, Had an experience my 500GB HDD (it was OEM of HP) just turned to death and it doesn’t like to boot even its spindle motor is running well.

It was the famous accient of HELL-GATE: Seagate firmware BSY error – Some Almost seagate HDD failed load firmware in sector 0, and then it going dead like a magnetic heavy brick.

When it happend to user, hellgate HDD not be recognized in BIOS of PC. It just turned to dead even its motors are still working.

After that mass accident, I have spend many bucks to recover HDD and determinded I will not, never buy hellgate again.

People who read this words, you should worry about just dying HDD if your slot fasten with label of “Seagate”.

Sometimes server disconnected …

Disconnected Sometimes my poor server displayed as “disconnected”. Actually it is reason of my cheap AP router as known as IPtime. Manufacturer of IPtime provides latest firmware for security, but limitation of HW could not be going to better. I have reorganized to putting thermal treat system and changed for good enery supporting, but its unstable not be better. Actually I want to buy new router but reality don’t give me money and chance.

Ok, I believe someone visit my small server and be helped. And I will try to keep my little server going to stable as I can do.

 

 Oh … Emily, please. Could you allow to buy a new router?

NOHON apple 8pin cable.

NOHON, this is a brand name of Chinese cable product company for supply Apple and Android charge and data cables. I found this little more expensive stuffs in Ali-Express by seraching durable iPhone cable.

DSC_0011-01

Most of cables from China, are far from durable in low cost as we know. But this cable has its own brand name and really more expensive than most of farbic coated cable shaped iPhone/iPad cables even certisfied MFi.

The reason has many differences from cheap, short lifed and slow charging cables like this.

DSC_0010-01

First, it has really unique USB-A port. It has double sided and I don’t care where is upside and doesn’t care how I need check wich side is correct to USB dock. Just I need know to this USB-A and I need put it into charging dock.

Second, kindly indicates my iPhone has been fully charged in different colors of LED light in side of Lightning.

DSC_0012-01 DSC_0013-01

You just put lightning port to iPhone/iPad and wait for its light turns to blue. It slowly blinks in red color while it going charge as below animated GIF.

GIF_20150805_013120

Cable is looks durable and well finished protecting parts like alumium shelters each lightning and USB-A ports. And comfort plugging idea is really brilliant like lightning port. I don’t need check which side is up. Charging speed is as like original Apple cable. By current detector displays charging continues on about 5V 1A. It may support over 2A for iPhone6+ or iPads. (I don’t have device to support over 1A)

Prices almost in 5 to 8 USD per one cable. Not much cheapper like almost hand-made not so durable cables. But you may forget “Oh, man, It’s again. I need to change new one.”.

In case of failure to using fl_xid();

I did try apply DirectX input to using joystick for my HID emulation, but my testing program failure in SetCooperativeLevel() API on dinput. At the result of analyse, I found FLTK API fl_xid() returns wrong HWND value from debuger.

inspection01 Just inspected real HWND(handle of window) value with Process Hacker. It was something wrong in internal value of calling fl_xid(); like below image.

inspection02

 

To verify in presumption of fact, I did compare with my FLTK DX8 joystick example, and it has exactly right HWND value in calling fl_xid();. Difference is only multi window in one program. Is it a cause of wrong HWND?

inspection03

Whatever is reason, I need change my code to getting HWND in source code.

It was just simple, and GetWinHandle() is following.

I don’t have time to know what’s wrong in fl_xid(), but it will be good solution to using DirectX devices in FLTK windows program.

 

FLTK+MinGW+DirectX8, Joystick example

Joystick image got from Google search... Here I made an example source code with Code::Blocks+MinGW-W64+WINE project directX8 library for using joystick.

You should know this project limited to under Windows32 platform, but You can make fast faced simple game without DirectX surface, only using FLTK and Direct Input.

I recommend to using my FLTK-1.3.3-ts library for compile this example to running without strange graphic crash. (visit here: https://github.com/rageworx/fltk-1.3.3-ts )

Source code is open, you can modify, republish.

To download file, just click below. Compressed with 7z and you may need Code::Blocks and MinGW-W64. And archived library is a part of WINE project – DirectX8.
