This application builds on an OpenCV face detection sample, but adds a black mustache on the faces detected and (now) uploads the picture to Twitter!
You can see it in action in a video interview at DESIGN East:
There was also a video taken at CES 2013
BeagleStache premiered at DESIGN East Theater during the Gadget Freak DIY Lab on Sep 19, 2012 (slides). More information about how it was created is referenced below.
The BeagleStache was also featured at Maker Faire NY 2012:
Drew Fustini also did a very nice “BoothStache” using BeagleBone Black at DesignWest 2013 and did a very nice write-up.
How to build one
Follow the instructions on the Google Doc presentation:
- Buy BeagleBone.
- Buy PS3 Eye.
- Buy BeagleBone LCD3 Cape or another power source.
- Buy BeagleBone Battery Cape.
- For tweeting, buy Iogear GWU627 Ethernet-to-WiFi adapter and tether it to WiFi. To overcome the limitations of the small screen, you should probably configure it separately to the WiFi and then connect it to your board.
- Assemble it together into some kind of case.
- You might want to update BeagleBone to latest image.
- Boot board and login to console, perhaps using the built-in USB networking and Gate One.
- Clone repository and build:
root@beagleboard:~# git clone git://github.com/jadonk/stache root@beagleboard:~# cd stache root@beagleboard:~/stache# make && make install
- Edit config.js to include your tweet message, location of your LED control files and API keys for your Twitter account. To acquire your keys:
- Sign in at dev.twitter.com.
- Create an application on the “my applications” page.
- Set the access level to “read and write”.
- Create your access token.
- Make sure the date/time is set properly because Twitter requires it.
- Double-click the BeagleStache icon to execute ‘runstache’ and start the app running. Be patient and try not to start it up multiple times.
Alternatively building on BeagleBoard-xM, instead of BeagleBone
I believe I used this SD card image.
