So much time wasted every day standing at my sink filling water bottles. I finally decided that I need to automate this process. I am going to use a Raspberry PI, some custom water valves driven by a servo, a water filter and instant hot water heater to make my own automatic hot and cold water dispenser with presets so I can walk away while the water bottle, coffee or French press fills itself!
