Step by step procedure (the futuristic version)


Step by step procedure (the futuristic version)

I want to emphasize the room for improvement in labor automation in what's been mentioned so far, which runs up to the time the boil has finished.

I think if we can draw insights here compared to the simplified version from the proliferation of smart devices that will come into the hands of billions of people in the coming years. It is essentially a magic box that can do pattern recognition, workflow reconaissance and act as a augmented reality personal assistant in the 'cloud' and in your eyewear and other buzzardwords. Consider also the mechanization of industry and mechanical advantage incorporated as another power. Twenty pounds of grain weighs a lot more sopping wet, but an automated pulley system integrated with the rest of your sensor/actuator framework may have 50 other uses.

1) A keg has been retasked from producing wax candles or cheese or for home cooking and is dismantled from that purpose.

2) The home's hose water supply is placed into the keg, a verbal command is given to begin filling the keg with hot water.

3) If it is already plugged in to a solid state relay cord and drill, a remote controlled grain-mill begins milling grain into a grain bag as the system becomes aware that a brew day is now the current focus. For a single type of grain per milling station (bucket) or for a single anticipated recipe this is a solved task but how to economize hardware for milling multiple types of grain to produce different grainbills on demand could be its own project. How might a project like that be reused in other places? Would different hoppers full of grain revolve over the mill?

4) This filling of the keg and milling of the grain will happen simultaneously. Neither will be done by the time the user has plugged in 2 (for five gallon batches) or 4 (for 10 gallon batches) relay/actuator cords with one jeenode and battery power source for each. These jeenodes furthermore must already have been flashed with the correct "recipe". This is to step through temperatures at the right time or if a more central intelligent (laptop/smartphone) does this, then at least to know that the jeenode is a temperature sensor or a 120 volt heat source.

One potential way to flash jeenodes with code may be via flashes of light from javascript on a web browser to a light sensor on each jeenode because a device this cheap and versatile is more labor intensive than a smart phone. Raspberry Pi sized servers could interpret these flashes for jeenodes.

5) When the right depth is reached the system has already inferred from the flow rate to alert the user a minute beforehand that in one minute the heating elements will be safely submerged in the rising water, at which point the cords themselves and safely be plugged in. And these heating elements are now under the control of the program itself.

6) The grain bag may now be mounted to a pulley as the water heats to the strike temperature since it will be done milling by this time. This pulley could be a pneumatic or hydraulic actuator or it could be your friendly neighborhood open source hydraulic tractor if it can spare a minute (checking the status of the tractor for availability prior to brewing could be a jeemon (jeemon is dead, long live jeemon!) hook).

The notebook section provides a way for you to store and share information with your group members. With the book feature you can:

  • Add book pages and organize them hierarchically into different books.
  • Attach files to pages to share them with others.
  • Track changes that others have made and revert changes as necessary.
  • Archive books that are no longer of interest to the group. Archived books can be reactivated later if needed.
