(Why Google is suspects that my kids are drug dealers
and why we’re looking for a food-safe fencepost)

PARC - but not what this project is about

Dork!

The challenge
• Advice from Mike: Pick a topic that interests you
• I now work on a software project at PARC, so I don’t have HW to talk about
• I’m busy so I don’t do as much fun stuﬀ at home as I would like
• Everything I do in hardware these days is more sketchy than a sketch
Slow Jam Sketch
• If you use really slow material, is it still sketching?
• i.e. working with biological and chemical constraints
• The story: Why Google is pretty sure my kids are drug dealers and why I’m
looking for a food-safe fencepost
• Let the children lead the way
• And so the story begins...

Hydroponics System
Reservoir with pump and float switch
Types of Hydroponic Systems
• Ebb and flow system
o
Water level is fluctuated
• Wick System
o
Simplest System
• Drip system or Dutch Bucket
o
Bucket with a drip system type water supply
• Deep water culture (DWC)
o
Roots hang in root chamber full of water/nutrients
• Nutrient film technique (NFT)
o
Thin film of nutrients
• Bubbleponics
o
Deep water culture system with water pumped to
the top
NFT
Aquaponics
• Aquaponics is the cultivation of plants and fish in a recirculating
environment
• The waste materials of the plants are being fed to the fish while at
the same time the waste of the fish is used in fertilizing the plants
and vegetables
Nutrient rich water
Plants clean
and filter
water
Fish muck up
water
Clean water
Aeroponics
• Aeroponics is the process of growing plants
in an air or mist environment without the use
of soil.
• A nutrient solution is used to provide food for
the plants
• A fogger or mister is used to aerosolize
nutrients and water in the root chamber
Types of Aeroponic Systems
• High pressure aeroponics
• Fogponics
Tribe Awesome Aeroponic Garden
It is a combination fogponics and deep
water culture system.
If you trim the roots, you can make it a
strictly fogponic/aeroponic system

Root Chamber & Fogger
Fogger Technology
• Piezoelectric disk vibrates water at 4 megahertz
• Fogger fills air with microscopic drops (5-10 microns)
• Plant pores absorb the nutrients and water from the droplets
• Allows for very controlled amounts of nutrients to be dispensed to
plants
Benefits: Requires less water, nutrients, and
pesticides...
• Reduces water usage by 98% (uses up to 65% less water than
hydroponics according to NASA)
• Fertilizer usage is also reduced by 60%
• No pesticide is typically needed
...all the while maximizing crop yields!
(http://www.nasa.gov/vision/earth/technologies/aeroponic_plants.html)
Benefits: Fast Plant Growth
• 13 crop turns in aeroponics vs 5 crop turns in soil per year (http://
www.foodrepublic.com/2011/08/18/5-things-you-don%E2%80%99t-know-about-hydroponics)
• Grows twice as fast a hydroponic systems (http://how-to-x.info/2038335-aeroponicsvs-hydroponics.htm)
In only 12 days!
Before
Soil
Hydroponic
After
Benefits: No Weeds
• You grow only the plants you want, not 'weeds'
• No herbicides required
Benefits: Control
• Precise control over
o nutrient concentration and composition
o moisture
o diseases that can kill or harm the plant
Benefits: Little space required
Little space required
• Aeroponics gives you the ability to grow plants in places that you
would not otherwise be able to with regular gardening and
agriculture
• Aeroponics does not use soil which saves space-and a mess
• Because aeroponics does not
use a lot of space plants can
grow inside
• This is helpful in places where
weather is unpredictable or
unfavorable for a garden.
Benefits: Mobility/Portability...
• Aeroponics systems require little space
• Systems are self contained
• Entire system can be moved
Benefits: Educational Value
• Great way to learn the biology of a plant
• The roots of the plant are visible
o
make more acute observations of roots
Benefits: Easy System Maintenance
• Systems can be highly automated
• Your system will require only
occasional maintenance
o
o
o
Change water every few weeks
Replace nutrients
Clean the fogger

Raul from Valley Verde
http://valleyverde.org/
Where are they headed from here?
• Build a system for Raul
• New form factors - Go vertical
• Solar Power
• More sensors - Monitor pH, Salinity etc
• Dispense nutrients and water autonomously
• Sense gases
• Use cameras to sense growth phase
• Aquaponics
• What does it mean to give plants a virtual life
Projections - looking forward
• All the systems, tools, sharing, business models that we are working on is
stuﬀ the next generation takes for granted (so we better make it work!)
• They assume that they are inheriting a “used” planet and it’s gonna need
some work
• Don’t be distracted by the CPU - You can sketch in hardware that has no
software
• Growing plants without soil is kind of like teaching kids without school Homeschooling is verrrry interesting
