PLAN WTF?!
THE FIRST DRIVE
THAT WORKED!
THAT SUCKED!
INSTANT ITERATION

Always
Measure
•Time is critical!
•Start measure NOW!
•No time for normal
development process.
•Iterative prototyping
followed by field testing.
DEVELOPMENT MILESTONES
1 Month: Functionality, bare minimum
3 Months: Usability, improve design
Long-term: Manufacturability, cost, quantity
1 3 Long-term
•Netbook
•Geiger counter
•USB GPS
•Rugged enclosure
•Cables
Phase I Prototype
Time-to-deployment:
1 week
•Self-contained
•Arduino
•Custom shield
•SD card
•Geiger counter
•GPS
Phase II Prototype
Time-to-deployment:
2 months
•Single custom PCB
•Bare Geiger tube
•Smaller form factor
•Manufacturability
•Cost cut by half
Long term design
Starting production soon
MAJOR / MINOR
NEW DEVICE SHIPPING EVERY 3-4 MONTHS
• bGeigie - get data now!
•bGeigie Mini - have other people get data!
•bGeigie+ -- power users get data easily!
•bGeigie Stealth -- measure w/o attracting unnecessary attention
•bGeigie 3 -- make bGeigie manufacturable
•bGeigie nano kit -- remove manufacturing need
REACTION
100+ BGEIGIES
300+ STATIC
VISUALIZATIONS
SIMILAR RELEASE APPROACH/SCHEDULE
•no map for drives, only static sensors
•Google maps - each drive data on a separate map!
•Fusion tables - see all data on one map (Japan only)
•GeoSense - handle millions of data points - see the world!
•iOS App - location aware maps on iPhone / virtual geiger
•What is the next challenge? (show changes over time, interpolate, etc)
6 MONTHS = 1M
TODAY > 5,000,000
