ICAN AERO 007

< I bought a frameset on AliExpress >
ICAN AERO 007 is not a new product, it was released in about 2016. But some specifications were updated until 2019. And many bloggers say it is a good frame. After deep research, I decided to buy it.

< Compatibility >
If you mix any SHIMANO’s parts, you should check SHIMANO compatibility chart.
2018-2019 version 3.8 ( PDF )
Product information ( Online )
I carefully checked it to mix old 105 5800 with new 105 R7000 and Ultegra R8000. My SHIMANO’s components on this bike are officially compatible.

< Frameset appearance >
“ICAN” logos and orange paint looks not so bad for me. I put glass coating on it to keep away from small scratches.

< Special tool >
I bought magnet pickup tool like Stahlwille 12600-270g. ( It is not same as my tool. My tool is SRO-15 [Amazon.co.jp]. SRO-15 is only sold in Japan, but Stahlwille’s 12600-270g is similar product as SRO-15. ) It will help you to fit internal cable on the frame. The diameter of my tool is 4mm.

< Customize cassette CS-R7000 11-28T to 12-28T >
I bought Shimano’s small parts below to make a bit more close-ratio cassette.
12T : Y1PJ12100
13T : Y1PJ13100
16T : Y1PJ16000
17T : Y1PJ17200
Remove 11T, 12T, 13T, 17T from CS-R7000 11-28T, then insert new gears above.
You can order them at real bike shops in the world. Please tell the model numbers. Maybe it is easy to buy them online only in Japan.
( It is also a practicable way for CS-5800. )

< How is this bike? >
The review below is after I rode this bike over 2,000 km.
This frameset is really hard and not so light. It is difficult to break. It also means this bike efficiently convert leg power into propulsion. But I felt “PRO Vibe Alloy Compact Handlebar” is too hard for long ride. It damaged my hands and arms when I rode over 200km. I will buy a carbon handlebar to replace it. This frameset is very hard, so I should assemble soft or endurance parts. My wheelset and tires are a bit heavy for climbing. But they have high stability on down hill. On riding the bike, I felt nothing bad about the frameset. Bad points are basically depend on the other parts. Considering everything, ICAN AERO 007 is really good frameset. If you are thinking about this frameset, I highly recommend you to buy it.

Yi 4K – Shooting test on road bike

I bought Yi 4K and tested some settings on it.
I explored [ the best setting for the quality to play 1080p on Youtube ]
My microSD is Samsung 64GB EVOPlus Class10 UHS-I U3.
My mount is TrustFire GoPro Bike Mount. This is Garmin/bryton cycle computer mount with GoPro mount.

< Started test with 1080p 60 FPS >

This video was shot by the settings below.
Resolution : 1080 ( 1920×1080 ) 60FPS
Field Of View : Wide
Metering Mode : Average
Auto Low Light : OFF
Video Quality : High
WB : Auto
Color : YI Color
ISO Max : Auto
Sharpness : High
EV : 0
Electronic Image Stabilization : ON
File Size : 4G
Adjust Lens Distortion : ON

I think it has a bit too much image noise. I am going to change resolution higher to decrease the noise. By the way, I have known its microphone is bad for windy situation like riding a bicycle, but it doesn’t have a terminal to connect an external microphone.

< Change resolution to 2.7K and keep 60 FPS >

This video was shot by the settings below.
Resolution : 2.7K ( 2704×1520 ) 60FPS
Field Of View : Wide
Metering Mode : Average
Auto Low Light : OFF
Video Quality : High
WB : Auto
Color : YI Color
ISO Max : Auto
Sharpness : High
EV : 0
Electronic Image Stabilization : ON
File Size : 4G
Adjust Lens Distortion : ON

Image noise considerably decreased. Maybe even if watching by 1080p on Youtube, uploading by 2.7K has advantages about quality. Next, for low spec computers and make bitrate lower to shoot longer, I am going to change FPS 60 to 30. I am also going to test “Adjust Lens Distortion” OFF, I guess it may incompatible with “Electronic Image Stabilization”.

< Keep resolution 2.7K and change FPS 60 to 30 >

This video was shot by the settings below.
Resolution : 2.7K ( 2704×1520 ) 30FPS
Field Of View : Wide
Metering Mode : Average
Auto Low Light : OFF
Video Quality : High
WB : Auto
Color : YI Color
ISO Max : Auto
Sharpness : High
EV : 0
Electronic Image Stabilization : ON
File Size : 4G
Adjust Lens Distortion : OFF

Any shapes on this video does not look so strange, so I think “Adjust Lens Distortion” is not necessary. But 30 FPS is not good for image quality especially in dark place. But I was surprised that video quality is really high, even though I shoot without any gimbal and I did not add any effects on PC.

Next, I am going to re-try 60 FPS. I change “Video Quality” medium to shoot longer. Also I bought 128GB microSD ( officially not supported ) and Shock-Absorber on AliExpress. My 128GB microSD is Samsung 128GB EVOPlus Class10 UHS-I U3.

< Keep resolution 2.7K, change FPS 30 to 60 and set “Video Quality” medium with shock absorber >

But! This absorber never stop strong vibration. It is impossible to shoot. I guess it is bad for riding a bicycle. I waited 3 weeks for the shipment from China …
Well, I am going to re-try without this one.

< Keep resolution 2.7K, change FPS 30 to 60 and set “Video Quality” medium “without” shock absorber >

This video was shot by the settings below.
Resolution : 2.7K ( 2704×1520 ) 60FPS
Field Of View : Wide
Metering Mode : Average
Auto Low Light : OFF
Video Quality : Medium
WB : Auto
Color : YI Color
ISO Max : Auto
Sharpness : Medium
EV : 0
Electronic Image Stabilization : ON
File Size : 4G
Adjust Lens Distortion : OFF

I shoot in the daytime. This camera is good for bright place. During fine weather, quality is really high. But latter half on the video, quality got lower with cloudy weather. I was not able to find big differences between “Video Quality” high and medium. 128GB microSD occurred no problem on shooting. Temperature was from 10°C ( 50°F ) to 18°C ( 64°F ). File size on Windows was 115.95GB. I do not know why but it was 124.5GB on Mac.

< A little bit trouble >

Yi 4K separates files each 4GB. Also on long ride, I got some breaks and stopped shooting during having breaks. I use Avidemux to combine them. 115.95GB video has no problem playing on PC. But Youtube occurred a problem after uploading. After cutting last a few frames by Avidemux, this problem solved. I do not care about this problem, because it is a rarely problem and easy to be solved.

I developed bookmarklet to push “kudos” buttons in a lump for Strava.
https://github.com/mecrazy/stravaKudoser

< Sometime it is troublesome to push each “kudos” buttons >
If many people follows you or you follow many people, it can help you to push “kudos” buttons. Use it on PC like Windows, OSX or Linux. It is not tested on smartphones like Android or iOS.

I developed follower checker for Strava.
https://github.com/mecrazy/stravaFollowers

< Strava doesn’t have such functions >
People follows me but someone unfollow me immediately. But it is not easy to find who unfollow me. So I developed this bookmarklet to find people who unfollow me. Use it on PC like Windows, OSX or Linux. It is not tested on smartphones like Android or iOS.

I built PhantomJS 2.1.1 for Raspberry Pi

I built PhantomJS 2.1.1 for Raspberry Pi. It can also run on any armhf architecture machines.

I used Debian on ARM VPS on https://www.scaleway.com/ and follow this page to build it.

Please download from https://github.com/mecrazy/phantomjs-binaries.
( After my pull request allowed, I will edit the link on this blog to “https://github.com/avaynshtok/phantomjs-binaries”. )

I use Raspberry Pi as a testing machine for any server applications like web scraping. But there were no PhantomJS binaries for armhf architecture on the web. So I built it. Please use this binary, if you want. But I can not care any troubles and bugs when you use it.

< What is "PhantomJS"? >
PhantomJS is a web scraping tool with JavaScript API. It can capture web pages as PDF, PNG or some kind of picture file. If you want to know more about PhantomJS, please check http://phantomjs.org/.
