kotobuki At last, the future is here. RT @vomoder: Finally, weather forecasters
started reporting the radiation dose. I have been in SF movies.
vomoder @kotobuki Are you already working for a GM tube + ZigBee shield?

Utilizing SparkFun’s Geiger counter, and upload readings via Processing or oF and
share on Pachube will be a good way to start. Does anyone interested in
JavaScript part? I’ll be able to provide dummy data to start development.

• SparkFun provided me a board
• I wrote sketches for Processing and Arduino, then
published on a blog about 10 days after the accident
• Several people started monitoring and sharing in
response to the article

• The original stationary sensor network design was
based on the Arduino platform.
• An Arduino clone (Freakduino) + a custom shield
(the network chip and a high voltage Geiger tube
driver).
• The software was based on my Geiger counter
sketch for Arduino on github.

20. Conclusion
Lessons Learned
• Keep running a project is not so easy
• There are various way to contribute forming
‘information’
• Distributed collaboration is the key
