Speaking about technology, iOS 7 just got unveiled by Apple today. It was stunning, even myself couldn't believe that Apple would bring such a big change to iOS. Can't wait to get my hands on the new iOS 7!! It is 5:07am right now
Goodnight everyone, or good morning to some... As always, take care and I'll see you soon. Mum made quite a lot of dumplings today. I can almost say that I only ate dumplings today, OMG! I have some KFC Groupons that Dad bought. I think I should be going for some KFC tomorrow, instead of dumplings AGAIN
Today was boring as usual, stayed at home the entire day. I still didn't bank in my cheque. Now then I realize how difficult it is to deposit a cheque when there aren't banks nearby. I'm rather unproductive this holiday. Next up, I hope I can buy the season pass for USS so I can visit them all the way till November 30. It's only 88 dollars, so why not? Woke up having bad headache, maybe it is because I didn't sleep early these few days. Spent quite a lot of time improving the mobile experience for this web blog. I guess everything is working nicely right now. I dismantled my 2600mAh battery again and discovered something risky. Basically, every battery got its '+' and '-' leads isn't it? The supposedly '-' side of the battery is connected to the top of the battery's circuit board via a thin strip of metal contact. It was taped down to prevent the contact from touching the metal casing. From what I see, the taping job isn't done so well. After some use, it might possibly touch the metal casing causing a short circuit. I manually used my own tape to tape it nicely, so to make sure that it 100% won't touch the metal casing. Trying Roller Coaster Tycoon 3 Platinum on my laptop... Hopefully it is nice compared to the 1st iteration of Roller Coaster Tycoon. Yeah, my life is boring. I'm awaiting the release of iOS 7! Can't wait to try it out... As always, take care and I'll see you soon I love how my website looks with the new theme. Everything looks so neat and tidy here. Picture captioning is now working on mobile site, thanks to the incredible support team! Kudos to them for bringing quick and responsive service to its users!
Posted using Weebly app on Android As always, take care and I'll see you soon... Received the 2600mAh external battery that I ordered from eBay from $2.99!!
Turns out the battery is just enclosed in a metal casing. Revealing the internal battery parts number of 18650-A. A little research points the battery at being technically 3.7V, Wikipedia states that the battery is most commonly used for laptop batteries. It is only a single piece of battery connected to a voltage amplifier to push it up to 5V for charging mobile devices. Micro-USB cable included as well! A little math here: (3.7V x 2600mAh) / 5V = 1924mAh Conversion loss about 20% > 1924mAh - 20% = 1539.2mAh Battery specification from eBay: Input: DC 5V 500mA (Suggesting that it is better charged using computer USB) Output: DC 5.5V 800mA iPhone power input = 1A x 5V = 5W Battery power output = 0.8A x 5.5V = 4.4W (Technically not enough power) iPhone 5 battery capacity is at 1440mAh, therefore I should expect 1 full charge from the external battery. Considering the price at $2.99, it is really hard to beat! I've heard that those 20000mAh and 30000mAh battery contains sand instead of real battery. I should be glad that mine got no sand involved.

MST have ended, and my FYP's first assessment was completed today. The presentation was only given 10 minutes. I guess this is what many of us say "台上十分钟,台下十年功". My group spent a lot of time making the PowerPoint detailed and as smooth flowing as possible. I don't think it is time for me to reveal anything about my project here. I would if the time is right... hopefully soon :)
MST was okay, no good results anyway. In fact, it was rather disappointing :( |
