RPI is not good handling DHT11

Hello?

This is failure story about converting c code to python.

There is GPIO controlling library on Python such as RPI, wiringPI.

But they are not enough to controlling high frequency data.

some people already investigate about it.

Follow code return wrong values because frequency.

So I should hybrid c++ and python codes.

Change whole things.

Hello?


I decide to renew whole devices.




Finally, there is a lego frame for raspberry pi.

This one has motion sensor, humid sensor, camera, IR receiver.

I will use Django, python for gathering daily logs.

Fun coding guys :)

Wii fit scale for activity application

Many people who bought Wii, they has a wii fit scale. 

I am one of them. I find a way to use it.

There is a developer who already connect wii fit scale board to android.

https://github.com/paulburton/fitscales

It seems that there is a FitBit, Runkeeper sync feature.

S Health will be a another sync option. because they also have a api to sync data 

Samsung health idk

Anyway, I try to change the github code and try to add sync feature to it. 

Happy coding..
