Everyone Transit

I got an idea on how to solve the bus services real time information, it's using crowdsourcing technology. And I also developed an Android app for the first version. I called this solution "Everyone Transit".

•       Problem:

In most of the cities, especially in Populous cities, when you waiting for the bus at the bus stop, you don’t know where is the bus, when it will reach the bus stop and if the coming bus is crowd. So you may:

a.        miss the bus.

b.        take a long time waiting for the bus even in a very bad weather.

c.        can’t adjust your plan in time even the bus you waiting for is trapped by the traffic jam.

d.        can’t decide if get on the crowd bus or wait for the next bus may not that crowd.

•       Solution:

•       Develop a mobile device app that can gather users’ GPS data when they on the buses and some other bus information shared by app user, after data analysis on server(cloud) side,  we can get bus services real time information(bus position,  speed, passenger number on bus, etc.),  so other app user can check real time bus service information from app client  to avoid the problems above.

Here is the my android client link, http://www.appchina.com/app/com.example.everyonetransit

In this app, I provide a feature that user can set the destination bus stop, when bus is approaching the destination stop, app will alarm the user. When user use this alarm function, it will share some GPS information to my server side, and other app users can get this bus's real time information.

Call Note

I've got an idea on phone function, I name it "Call Note".

Problem:

–Some phone users may get lots of calls, when they check the call history, they want to know what has been discussed in some calls that they can’t remember.

–Some phone users just want to do a quick note for some important call when call hangs up.

Solution:

When call end, call note will pop-up for user to log some text and audio note. Of course, it can be combined with some cloud features and stored in the cloud server.

Android Bluetooth Remote Control Car

The thought of building a remote control car by myself since I was a kid, and I DIY many version of toy cars, boats in my childhood, but no one was remote controlled.

Fix my Lenovo Yoga Pro2

I bought a Lenovo Yoga Pro 2 couple months ago. Unfortunately, the volume increase button was not work suddenly. It might impact the laptop's warranty if I open the laptop and check the issue, so I send it back to Lenovo for repairing. I was told the board which contains the volume control buttons was broken,It took me 3 days waiting to get back my laptop. But I found out a new issue very soon, the screen rotation lock button was not working after the repairing. Actually, this is the reason why most of time I like to check these kind of problems by myself, they always make things worse. So, I open it up and found the root cause, the Lenovo guy forgot connect the button battery wires. Here is the photo after I open the laptop up:
