Wii-Scale
Wii-Scale turns your Wii Balance Board into a digital scale. Wii-Scale will automatically find your Wii Balance Board when it is connected to your computer. All you have to do is just stand on it :) No boring console interface, watch your weight being calculated in realtime on a beautiful web insterface.
You can also create multiple users for the whole family and see each members weight history. Wii-Scale runs on Linux and it also runs on a Raspberry Pi.
Wii-Scale is based on C++, node.js, AngularJS and communicates over the lightning fast WebSocket protocol.
Usage
Before you can use Wii-Scale, you need to have your balance board paired with your computer and connected. To start, just press the green "Connect" button in Wii-Scale and follow the on-screen prompts in the web interface.
The weight is calculated by taking the mean of 50 readings. Wii-Scale will ignore all weights under 30 kg to give you the most accurate reading possible. Oh, and all this will take about 3 seconds.
Installation
Wii-Scale runs most likely only on Linux. Follow these guides to install Wii-Scale on Ubuntu or Raspberry Pi:
To communicate with your Wii Balance Board you'll need a bluetooth 2.0 or 2.1 compatible device. You can find compatible devices here. Wii-Scale is based on the following dependencies Python 2, Python-pip and Node.js with npm and BlueZ bluetooth stack.
Install Wii-Scale
Download latest version of Wii-Scale:
cd <your-directory>/
git clone https://github.com/aelveborn/Wii-Scale.git --recursive --depth 1
cd Wii-Scale/
Allow non-root users to access balance board:
sudo cp wii-scale/70-wii-scales.rules /etc/udev/rules.d/
Run install:
mkdir build && cd build
cmake ../wii-scale && make
npm install --production
Run
npm start
Now the web server and Wii-Scale should be up and running at http://localhost:8080
Configuration (optional)
You can configure a different host, port and calibration.
Access the web interface from other computers
To open up the web server to be accessable from the outside, like if you'll running Wii-Scale on an Raspberry Pi or a server:
npm config set wii-scale:host 0.0.0.0
Web server port
Define a custom port for the webserver (default is 8080):
npm config set wii-scale:port 8080
Webserver host
Define a different host for the webserver (default is localhost):
npm config set wii-scale:host localhost
Calibrate Wii-Scale
If the scales weight is off by any amout you can calibrate it by your own by setting the calibration i Kg. So npm config set wii-scale:calibrate 2will add 2kg to your weight, default is set to 0.
npm config set wii-scale:calibrate 0
Update
To update Wii-Scale, grab the latest version from GitHub:
cd <your-directory>/Wii-Scale
git pull origin master
Update Wii-Scale by running install:
cd build
make
npm install --production
