This is my kegerator. A little over a year old. I found some old scales with RS232 output and a USB temperature sensor, and then I wrote some custom software to monitor the temperature and how much beer is left in each keg. All of which I can monitor realtime anywhere from my phone.
The "talking" part is other software I wrote for parties where it will say things when people pour a beer, or yell at you if you leave the kegerator open too long.

So close to my "plan"!
I was thinking rfid chips that measured temperature and pressure of my kegs would also have a image code.
The rfid reader in my fridge would sense which kegs were being served and thier location as well as the weight (subtracting the tare of course). The on-board fridge computer could then read and display an image of the beer label with the temp, pressure and %full. It would also hit my brewing server to display OG, FG and ABV.
The information would be rendered on 3"x4" OLED screens on each tap handle.
A combination of keypresses on the OLED tap handle screen would promt a multi-media display on the freezer mounted LCD which may include video, recipies and branding.
A thumbprint reader might be used for security or user preferences. Something along the lines of the Amazon, "95% of the people that liked the Mesquite Pale Ale also tapped the Ironwood Imperial IPA."
Of couse from there, it's just a short leap to have the webserver auto-update my HBT signature.
Unfortuately this board restricts HTML code and images in the signature, so I scrapped the whole project.
Get back to work!
