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
