I have been contributing to multiple crowdfunding campaigns in the past years. Fortunately, most of the campaigns I contributed were successful and I received the products eventually. I think it is worthwhile to write (unboxing) blog posts for these products - as a log of what I contributed in the past, and also to let more people to know about these products. So here is the first product that I would like to write about: Atmotube.
話說這數年間，眾籌逐漸興起，我也投資了若干個項目。慶幸的是，我所投資的眾籌項目多數都集資成功而且產品亦成功付運（當然延誤是在所難免）。我決定在這裏為我收到的眾籌產品寫寫（開箱）博格，當作是自己的眾籌投資記錄，順便讓多些人認識這些產品吧。第一個要寫的產品，就是Atmotube。
The Atmotube campaign started in early Nov 2015 on Indiegogo, and eventually completed with 338% of funding goal reached on 09 Jan 2016. The Indiegogo campaign page can be found here.
Atmotube的眾籌活動於2015年11月初在眾籌平台Indiegogo展開，最後於2016年1月9日成功籌集到比目標金額多超過兩倍的資金。Indiegogo的眾籌活動網頁在此。
I backed the Atmotube campaign in early Jan 2016. At that time the estimated delivery time was Mar 2016. However, I did not receive my Atmotube until last Thu (09 Nov 2017). That means it was nearly 2 years after the Atmotube campaign started. And this is indeed my longest wait to receive a crowdfunding product (of course except those campaigns that eventually are known as scams). In fact, I was thinking I would not be receiving anything from this campaign until I got an email from the Atmotube team around 2 months ago that they would like to confirm my shipping address.
我是於2016年1月初獻金的，當時預計的付運時間為2016年3月。當然不出所料，交付時間不斷延後，而我也打定輸數，以為這個項目也會「走數」收場。想不到大約兩個月前，我收到Atmotube團隊的電郵想跟我確認收貨地址，算是給我一點小驚喜。最後我在上週四（2017年11月9日）收到了我的Atmotube。（Atmotube團隊算是良心團隊吧？兩年來默默耕耘，真是要給這個以俄羅斯人為主的團隊給讚！戰鬥民族是不能小覷的！）
So what is this Atmotube all about? It is a portable air pollution monitor. You can bring this 40-gram little device with you, and connect it with the mobile app to monitor the pollution status of air around you. Atmotube is able to detect the volatile organic compounds (VOC, e.g. formaldehyde, benzene, etc.) and carbon monoxide, which would cause irritation and affect people’s health. The Atmotube team introduced a parameter called Air Quality Score (AQS), ranging from 0 to 100, to quantify the air quality (the higher the better). At the same time, the Atmotube can measure temperature and humidity.
那其實這支Atmotube有啥功用的呢？其實它是一個可以隨身攜帶的空氣監察儀器。將這根小管子聯繫上它的專屬app，就可以在智能電話上實時看到周遭空氣質素的情況。Atmotube能夠量度温度和濕度，並探測空氣中的揮發性有機化合物（VOC，如：甲醛、苯等）和一氧化碳，再以0至100分的空氣質素評分（AQS）量化空氣質素（越高分空氣質素越好）。
The following is the unboxing of my Atmotube:
以下為Atmotube的開箱過程：
Cylindrical packaging
圓柱體的包裝。
Content in the packaging: USB Type C cable × 1, carabiner × 1, user manual × 1, Atmotube × 1 (in the paper tube)
包裝內有一條USB Type-C電線、一個金屬扣、一份用戶手冊、以及Atmotube一支（在紙筒內）。
Atmotube: airflow mesh on top, a RGB LED and a round button at the side.
Atmotube頂部有採集空氣的氣流濾網，管身有紅綠藍LED及一個圓形按鈕。
Atmotube: the other side.
管身的另一面。
Atmotube: USB Type-C socket, a half ring for hanging to the carabiner.
底部有USB Type-C端口，以及一個半環扣。
After switching on, the Atmotube would take up to an hour to warm up, before it can take accurate readings. When pressing the button, you can read the colour of the LED light to know the air quality.
啟動Atmotube之後，它需要一段可長達一小時的暖身過程，才能準確測量數據。按下按鈕，便可以憑LED燈光顏色得知目前的空氣質素：
- Blue 藍色: Good 良好 (AQS 81-100)
- Green 綠色: Moderate 中等 (AQS 61-80)
- Yellow 黃色: Polluted 污濁 (AQS 41-60)
- Orange 橙色: Very Polluted 非常污濁 (AQS 21-40)
- Red 紅色: Severely Polluted 嚴重污濁 (AQS 0-20)
The mobile app, which has versions for Android and iOS, is available for free download. Once installed, the app will connect the Atmotube via Bluetooth 4.0 LE and obtain the readings of AQS, humidity and temperate.
Atmotube的免費專屬app提供Android及iOS版本，會利用低功耗藍牙4.0與Atmotube連線以獲取AQS、温度及濕度讀數。
The app would also show the total time measured and average AQS score.
專屬app亦提供介面顯示監測總時間及平均AQS分數。
There is also a screen showing the full history of measure during the day.
另有一個介面顯示每天的監測歷史數據。
The app can also record the location of readings taking, and display on Google Map. If you want to, you can share the location air quality readings with Atmotube team, so Atmotube team will be able to create a worldwide air quality map for public viewing.
專屬app亦會紀錄監測的位置數據，然後在谷歌地圖上顯示。用戶可以選擇是否將空氣質素及位置數據分享給Atmotube團隊，讓他們製作全球空氣質素地圖，並開放予公眾參考。
There is a configurable notification to alarm you on bad air quality. (Default is to notify when AQS drops below 50.)
用戶亦可在專屬app中設定空氣質素欠佳的通知。（默認設定是當AQS跌至低於50就發出通知。）
One interesting thing is, it is not possible to switch off the Atmotube without the mobile app.
要注意的是，沒有使用專屬app的話，是不能關掉Atmotube的。
My comments:
我的使用心得：
The Atmotube is an interesting gadget to give you an idea on the air quality of the places you go.
Atmotube的確是一件挺有趣的小玩意，讓我對所到之處的空氣質素有所認知。
It is small in size (22mm in diameter, 66mm tall, weights 42g), so there should be no hurdle to bring it wherever you go.
Atmotube非常小巧（管身直徑22毫米，高66毫米，重42克），帶着它外出絕對不會是負累。
If the Atmotube is not connected to the app for hours, it could take the app a while to synchronize the readings recorded in the Atmotube. This appeared to slow the app a bit.
如果Atmotube沒有跟專屬app連線一段時間的話，再連線時會花點時間將數據同步，期間專屬app的反應會有些遲緩。
On the day I tried the Atmotube, most of the time I spent was either in air-conditioned indoor locations or on train. Air quality stayed between moderate and good. There is no obvious way to determine whether the readings from the Atmotube are accurate or not.
我試用Atmotube當天，大部份時間不是在有空調的室內，就是在地鐵列車中。期間它所測量到的空氣質素介乎良好下限至中等上限。然而，我是沒有辦法證實它的讀數是否準確的。
（所以當玩具玩玩就好。）Worst air quality was measured in a lift that was full of passengers in the office building – not surprising but interesting!
當天空氣質素最差的讀數，出現在早晨上班時間辦公室大樓滿載的升降機內──不意外啊！
Next time I will share some other crowdfunded products I received. Stay tune!
下次會再跟大家分享其他我在眾籌項目中投資所得的產品。有興趣的話可以留意喔！
