Instrument the Golden Gate Bridge! Have a prototype structural health monitoring system up and running within a year Culler, Fenves, Demmel, Glaser Current Application:

The Berkeley "Smart Dust" Concept Spread thousands of wireless sensor nodes casually over an arbitrary area of interest They self-organize into a network conveying arbitrary information from any point to any other at whatever bandwidth is demanded.....while operating at incredibly low energy usage (i.e, off most of the time) to run for years on small batteries and harvested energy..and being extremely responsive in times of key activity..without ever bothering you about design considerations, intended usage, faults, or constraints From Culler (Stevie wants to be 6 foot tall)

Achieving this dream requires a broad-based team approaching the pieces as part of a system Cohort: David Culler – computer science, electrical engineering Greg Fenves – structural engineering, computer science Roger Howe – electrical engineering, MEMS fabrication Al Pisano – mechanical engineering, MEMS Kris Pister – electrical engineering, smart dust Tim Sands – materials science, microfabrication Nick Sitar - geoengineering, geology Me – GeoEngineering, Philosophy, driller, vision thing Students: Laurie Baise: PhD – GeoEng; MS - Seismo; Prof. Tufts Chen Min: BS, MS - EE; PhD - Civil Systems JianYe Ching: MS, PhD – GeoEng; MS - EECS; Housner Fellow, CalTech Dom Galic: MS, Appl.

Race/deadlocks still exist in sensor board driver code. Weather and air quality concerns limit controlled burn opportunities. We have to be able to move fast when necessary. “Uplink” details for remote deployment are still sketchy. Current FireBug Tasks
