5. Five Virtues: ARG Embodiment
With increasing maturity,
activity which does not give
back results of tangible and
visible achievement loses its
interest.
(John Dewey, Democracy
and Education 1916).
Play and games are “relief
from the tedium and strain of
‘regular’ school work.quot;
11. Five Interfaces: Pufftron Power
PoE
48V over unused wires in cable
Aesthetic and practical benefits of only having one
connector
RJ45 Connector is robust
Linear Regulation (first version)
Heating Power = Current * Voltage Drop
ex: Cell Modem 2A * (9-3.8)V =10.4W of heat
Impractical for PoE at 48V
ex: 2A * (48-3.8)V = 88.4W of heat
Switching Regulator (MAX5090)
More complicated implementation
More supply noise
90+% efficient
12. Five Senses: Light
Sunlight is the source of
all energy around here.

light has detrimental

13. Five Senses: Temp. and Humidity
Temperature, to track
heat waves and global
warming
HVAC homeostasis
produces straight
temperature lines for
indoor sensors. Sensirion SHT-11: Digital
Outdoor sensors read Temperature and Humidity
distinct day-night cycles. Sensor, accuracy and
precision are high
A green aesthetic would
value the diurnal cycle over Precalibrated
homeostasis. 14-bit ADC
2-Wire Serial Interface
14. Five Senses: Noise
Noise pollution leads to
hearing loss dB (air pressure) sensor via
Great indicator of place microphone, accuracy is low,
and activity precision is moderate,
Easy to test on sensor calibration is poor, plenty of
interactively averaging, average of
Great data from maxima are more revealing
Zellerbach Hall and than plain averages.
Zellerbach Parking in
Berkeley.
A green aesthetic would
seek to lower baseline dB.
15. Five Senses: CO2
DCS 305e Sensor:
Laser CO2 absorption
Tomato Quintet type: accuracy is moderate and
CO2 from human breath, precision is high, device is
rotting plants, and calibrated but drifts over periods
combustion (cars, of two years and needs to be
industry, smoking) recalibrated, consumes much
concrete curing and power. Interface by pretending to
deep cleaning be LED driver.

A green aesthetic promotes
data transparency.
16. Five Senses: VOCs Figaro 2602
electrochemical VOC
sensor, broad range of
sensitivities, accuracy and
precision are moderate,
Volatile Organic
but good enough to see
Compounds include in
cycles of pollution and
alcohol (beer!), methane,
regeneration.
tetrachloroethylene,
solvents, paint
Dry cleaners observed
buildup over week,
decided to vent more, but
energy cost was too high.
A green aesthetic would
reduce frequency and
increase regeneration
17. Five Interfaces: Pufftron Comm.
Communication via SMS:
Telit GM862-Quad Cellular
Modem
Strange Interface (implement faux-
pushbuttons)
bursts to 2A of current consumption
when transmitting
TX: AT&T Unlimited SMS plan
RX: 25 * 60 * 24 * 31= 1.1 Million
Messages /Month Not viable for international
1. At $0.02 per SMS for gateway deployment because different
service: 1.1M*.02 = $22k/Month cell companies require custom
2. Or use AT&T SMS to email firmware and custom plans.
gateway (text to 111)
Backend: postfix -> procmail -> perl
script that populates DB
18. Five Interfaces: Pufftron Comm.
Communication via
Ethernet:
WizNet100SR Daughterboard
requires PoE RJ45 connector
with magnetics
Gets IP via DHCP
Connects to hardcoded Server
IP
Streams serial from
Next Steps:
Microcontroller (AVR) to
Wifi! (ZeroG)
remote server (176 line of Perl)
Server:
Accepts multiple
connections
gets data (querystring
format)
26. Five Interfaces: Community Stories
“A genuine community life does not
organize itself in an enduring way
purely spontaneously. It requires
thought and planning ahead. The
educator is responsible for a
knowledge of individuals and for a
knowledge of subject-matter that
will enable activities to be selected
which lend themselves to social
organization … and in which the
activities in which all participate are
the chief carrier of control”.
–John Dewey,
Experience and Education, 1938
32. Five Interfaces: Direct Action
“Gardening … need not be taught
either for the sake of preparing future
gardeners, or as an agreeable way
of passing time. It affords an avenue
of approach to knowledge of the
place and farming and horticulture
have had in the history of the race
and which they occupy in present
social organization”
–John Dewey
Democracy and Education, 1916

Physical power connector
Means of Remote Telemetry
Wired: Ethernet, USB, Serial
Wireless: Bluetooth, Zigbee, WiFi, Cellular
Local Display

37. Power
Initial Implementation: Linear Regulation
HeatingPower = Current * Voltage Drop
ex: Cell Modem 2A * (9-3.8)V =10.4W of heat
Impractical for PoE at 48V
ex: 2A * (48-3.8)V = 88.4W of heat!!
Next version: Switching Regulator (MAX5090)
More complicated implementation
More supply noise
