  Introduction The Nuclear Accident • There was the Great Tohoku Earthquake on March 11th. • In the wake of the nuclear accident at TEPCO Fukushima Dai-ichi Nuclear Power Plant, media outlets were filled with information on the spread of radiation throughout Japan. • Since there was the lack of information, all kinds of rumors quickly spread across social media sites, often filled with incorrect or misleading information, and added to public confusion. • To make matters worse, the government and the company were constantly saying ‘everything was okay’ when it was obvious that it wasn't. The extent of the damage was only disclosed three months later. Open Hardware Summit 2011 | Shigeru Kobayashi TEPCO: Tokyo Electric Power COmpany

  Case Study 1 Japan Geigermap: At-a-glance http://japan.failedrobot.com Open Hardware Summit 2011 | Shigeru Kobayashi OK, let’s talk about three cases. The first case is Japan Geigermap.
• 12.
  Case Study 1 Japan Geigermap: At-a-glance | Overview • A map by Haiyan Zhang to visualize crowd-sourced radiation readings from across Japan. • This and other mapping projects were taking the Pachube feed, which came from a variety of independent and government sources. • This highlighted and interesting issue for Open Data, where the government had a network of radiation sensors around the country, but this data was not made in an open format. • Several individuals worked to scrape this information and turned it into an open data format to feed into Pachube. • The Japan Geigermap project worked to make the sensor information as clear as possible to citizens through design and user experience. Open Hardware Summit 2011 | Shigeru Kobayashi Instead, citizens could visit the government websites to gain this information.

  Case Study 1 Japan Geigermap: At-a-glance | History http://twitter.com/#!/haiyan/status/48535925248098304 Open Hardware Summit 2011 | Shigeru Kobayashi If I remember correctly, this was her first tweet about Geiger maps on March 18th.
• 14.
  Case Study 1 Japan Geigermap: At-a-glance | History http://jsdo.it/motoishmz/rdC2 Open Hardware Summit 2011 | Shigeru Kobayashi In prior to her map, a web developer, Motoi Shimizu, created a prototype of a Geiger map utilizing Pachube feeds on March 18th and shared on jsdo.it, an online code sharing and IDE for HTML5 by Kayac. So far over 13,000 views, and inspired many derivatives. Haiyan expanded his idea and implemented ‘Japan Geigermap’.
• 15.
  Case Study 1 Japan Geigermap: At-a-glance | Overview http://twitter.com/#!/haiyan/status/48885447346225155 Open Hardware Summit 2011 | Shigeru Kobayashi Then, she launched the first version of Japan Geigermap on March 19th. It was only one day after her initial tweet. So quick!
• 16.
  Case Study 2 Geiger Maps Jp http://geigermaps.jp Open Hardware Summit 2011 | Shigeru Kobayashi The next case is Geiger Maps Jp. I’m the team lead of this project.
• 17.
  Case Study 2 Geiger Maps Jp | Overview • A portal for radiation maps/visualizations and a list of affordable measurement tools such as Geiger counters. • Original idea was creating a map for the people living in Japan to let them check radiation levels of interested points to compare between points and the present and the past. • Due to the complexity of setting up and calibrating geiger counters, there was a need to organize and create standards around units of measurement, calibration, data feed format. • We discovered needs a portal of Geiger maps. Then we changed our plan and set up a portal on April 9th. • 12 contributors, available in 12 languages Open Hardware Summit 2011 | Shigeru Kobayashi Haiyan’s Geiger map has been really useful to know radiation levels of all over the country at a glance. We wanted to create an additional map for the people living in Japan to let them check radiation levels of interested points to compare between points and the present and the past. I asked on Twitter and a designer and a web developer responded, then we started the project. Through the discussions, we discovered needs a portal of Geiger maps. Then we changed our plan and set up a portal on April 9th and ask for volunteer translators to translate article into 12 languages.
• 18.
  Case Study 2 Geiger Maps Jp | A List of Hardware Open Hardware Summit 2011 | Shigeru Kobayashi There is a list of affordable Geiger counters, mainly Open Hardware products.

• 20.
  Case Study 2 Hardware | Geiger Counter • 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 Open Hardware Summit 2011 | Shigeru Kobayashi But it was out of stock on March 16th. So I contacted Nathan Seidle of SparkFun about availability, and he kindly provided me a board immediately. While waiting, I wrote a simple sketch for Arduino to simulate serial outputs of the Geiger counter. I got the board then published an article in Japanese on March 23rd. After that, several people started monitoring and sharing in response to the article.
• 21.
  Case Study 2 Hardware | Geiger Counter Twig • Developer: Seeed Studio (China) • Price: $42.8 (including a J408γ) • Sensor: North Optic J408γ (γ) • Interface: Twig (Seeed Studio’s Grove system for Arduino) • License: CC-BY-SA 3.0 http://www.seeedstudio.com/depot/ twig-geiger-counter-p-867.html Open Hardware Summit 2011 | Shigeru Kobayashi I also contacted Eric Pan of Seeed Studio about availability of GM tubes in China, and they responded very quickly. They published an article, ‘Radiation detector, help needed!’ on March 16th. So far, about 130 comments to the article, and they stocked affordable GM tubes in the end of April, and released an interface board for a GM tube in the end of June.

  Case Study 3 Safecast/Tokyo Hackerspace http://safecast.org http://tokyohackerspace.org Open Hardware Summit 2011 | Shigeru Kobayashi The last case is Safecast/Tokyo Hackerspace.
• 29.
  Case Study 3 Safecast/Tokyo Hackerspace | Overview • A volunteer group (10-12) doing monitoring, mapping, and visualization for public safety applications. • Started by a group of people a few weeks after the Fukushima Dai-Ichi explosions. • The initial idea was to scrape public websites for data and aggregate into one place. • Later on, Tokyo Hackerspace got involved and the scope was expanded to crowdsourced radiation monitoring, mobile data collection, and stationary sensor networks. • They proposed their idea on Kickstarter.com and funded successfully. • Keio University and various communications carriers are also getting involved now as well. Open Hardware Summit 2011 | Shigeru Kobayashi The core members of Safecast were Joichi Ito, Ray Ozzie, Sean Bonner, and Pieter Franken.
• 30.
  Case Study 3 Safecast/Tokyo Hackerspace | Map Open Hardware Summit 2011 | Shigeru Kobayashi This is the map by Safecast. The map covers over million points by both stationary and mobile sensor nodes.
• 31.
  Case Study 3 Safecast/Tokyo Hackerspace | Hardware • 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 Shigeru Kobayashi's Geiger counter software on github. Open Hardware Summit 2011 | Shigeru Kobayashi This is the prototype of their stationary node.
• 32.
  This is theoriginal one.
• 33.
  This is theprototype with a NetRad PCB.
• 34.
  This is theprototype with Wi-Fi.
• 35.
  This is thefinal prototype.
• 36.
  And they deployed.
• 37.
  Case Study 3 Safecast/Tokyo Hackerspace | Hardware • The mobile node is also based on the Arduino with a custom shield that includes a GPS module, SD card slot, and Geiger counter input connector. • The device gets mounted on a car and collects data every 5 seconds as the car drives around and saves it to the SD card. The data then gets uploaded and mapped. • There are close to a million data points now. Open Hardware Summit 2011 | Shigeru Kobayashi This is the prototype of their mobile node.
• 38.
  This is thefirst prototype.
• 39.
  In production.
• 40.
  The enclosures.
• 41.
  This is anexample of a node that is mounted on a vehicle.
• 42.
  Case Study 3 Safecast/Tokyo Hackerspace | Hardware • The Arduino platform allowed them to learn a lot and also to build out the hardware very quickly. They had working hardware and custom PCBs about 1.5 weeks after they started and proceeded to collect data. • Stationary nodes: Have about 35 stationary nodes set up, and the goal is to have 300 nodes up by the end of 2011 (with Keio University) • Mobile nodes: Have approximately 20 mobile Geiger counters deployed with volunteer drivers, mostly in Fukushima prefecture. They are providing drives and many are doing the drives daily, full-time. • They're designing the next versions of the Geiger counters based on Linux. Open Hardware Summit 2011 | Shigeru Kobayashi • These ones will be more focused on communications and will allow them to use all types of communications, make development easier, and allow us to do field upgrades. (Ethernet, WiFi, 3G modems, satellite modems)
• 43.
  Case Study 3 Safecast/Tokyo Hackerspace | Challenges • The main one is getting enough money to buy the hardware to build everything out (now getting better). • The other big challenge is the diversity of domain knowledge required to do all of this: hardware design, firmware, protocol stacks, web design, database admin, and visualization (they're currently in need of help). Open Hardware Summit 2011 | Shigeru Kobayashi • The funding issue is now getting better as the project gains momentum and now the issue is actually building things out. We're ramping up on the stationary nodes, and if we get on the delivery trucks, then we'll have to ramp the mobile nodes. • They're currently in need of help with the visualization and web design aspects
• 44.
  Challenges and Possibilities Summary • With utilizing Open Hardware, we can develop prototypes of radiation monitoring tools in a short term. • Online web services such as Pachube are helpful to share open data. • Since the whole activities and projects are extremely cross- domain, it's difficult to manage and execute quickly. • There will be many possibilities of Open Hardware for our daily life and serious situations such as disasters.
