Ballmer Bot

Intro

Raspberry pi controller drink maker to reach ballmer's peak.

The concept of Ballmer's peak stems from the xkcd article where it point in which you have had enough drinks to be at your programming peak. After another drink it is downhill and productivity is hindered.

This was the pump I used

Getting Started

run node server.js -h for help

Initial setup run npm install to start the script run

node server.js

If you want to develop locally ( without rpi, use the mock option mock ) to simulate gpio actions

node server.js --mock

Troubleshooting

For errors like

Error when trying to open pin 16
gpio-admin: failed to change group ownership of /sys/devices/virtual/gpio/gpio23/direction: No such file or directory

run gpio-admin export 16

If the problem still exists, build the newest version of gpio-admin yourself.

Choose a directory you want to put gpio-admin in, and run

git clone https://github.com/quick2wire/quick2wire-gpio-admin.git cd quick2wire-gpio-admin

If src/gpio-admin.c has

int size = snprintf(path, PATH_MAX, "/sys/devices/virtual/gpio/gpio%u/%s", pin, filename); change it to

int size = snprintf(path, PATH_MAX, GPIO_CLASS_PATH "gpio%u/%s", pin, filename); Then, run make

Then, run

sudo make install

@TODO

web dashboard to add drinks
Implement prep / flushing of the tubes
"Mixologist" Menu, on the fly drinks w/ input from the user at certain amount pours
Voice controlled drink delivery Wit quickstart
