Ringing a bell, throwing some cash, snapping your fingers and maybe even showing a little extra cleavage have all been used to flag down bartenders. But Sean Carney, creator of Barbot, can catch the attention of his bartender with a quick click of the mouse and a remote Internet connection.
The Barbot is an Internet-controlled liquor-dispensing robot that can mix a drink with up to five different ingredients. It offers a web interface that lets you know what ingredients are available, generates a list of potential cocktails that can be made with those ingredients, shows user ratings, and offers links to order a cocktail. Once you order a cocktail, it gets to work and can make you a drink in seconds!
After inputting your drink order, the Sitara-processor-powered BeagleBone Black controls three dual-H Bridge motor drivers, which are connected to peristaltic pumps that dispense the correct liquids into your glass. BeagleBone Black is connected to a USB Wi-Fi adapter so that you can order your drinks wirelessly. The computer runs Ubuntu 13.04 with Apache2, MySQL and PHP, bind and dhcpd installed. Apache2, MySQL and PHP are used to host the web interface, while bind and dhcpd create the Wi-Fi portal. The web server directly controls the pumps by using PHP to write into the GPIO sysfs files.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
