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.
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.
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
Node.js with npm and
BlueZ bluetooth stack.
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/
mkdir build && cd build cmake ../wii-scale && make npm install --production
Now the web server and Wii-Scale should be up and running at http://localhost:8080
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
Define a different host for the webserver (default is localhost):
npm config set wii-scale:host localhost
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
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
If you whant to make a code contribution, run a
grunt clean-build before you commit and create a pull request.
If you are a developer you can install Wii-Scale with all developer dependecies:
sudo python setup.py install sudo npm install
If you are a developer and whant to contribute to the project, then this is some nice commands to know about.
Run all tests:
grunt grunt build grunt clean-build
grunt will run
grunt watch and build the whole project.
