Pumping Station One’s Biosensor
Array, a finalist in the Great
Global Hackerspace Challenge,
consists of a series of electronic
tools designed to help middle
school and high school students
measure — and therefore learn
about — their own biological processes. The heart of the system
is an ordinary Arduino, and the
array consists of sensors measuring body temperature, oxygen
saturation, EKG, galvanic skin
response, respiratory volume and
frequency, as well as CO2 output.

LAST STRAW
Safe drinking water is a huge
issue in much of the developing world. With this in mind,
Swiss company Vestergaard
Frandsen developed
LifeStraw, a light, portable,
straw-style water filter. The
10"-long, 1"-diameter device
is simple to use: suck on the
straw to filter and consume
water; blow through the straw
to clean the filter. It filters
enough water for one person
for a year and removes most
of the bacteria, viruses, and
parasites. vestergaard-
