Tokyo Hackerspace has continued to evolve their DIY networked Geiger counter project. Our friend Takyen, forum member and Thermal Tweeter case designer, has been involved in this project. Here’s an update via Make:
We joined up with Safecast (RDTN at the time) and since then, almost all the core members of Safecast Japan are now Tokyo Hackerspace members. The office is also inside Tokyo Hackerspace. We started up a joint project with Keio University to create a radiation sensor network across Japan. The goal is 300 nodes by the end of the year and 1000 nodes by next year. The NetRAD boards were modified to accommodate this and we added WiFi so that it would make deployment and cabling easier. All the data is open and since then, Yahoo Japan started publishing their radiation map using our feeds.
We also are using special versions of our Geiger counters mounted on cars to geotag Geiger data and create maps.
My involvement was really minor (just some GUI related stuff for logging data real time), the real guys behind the project are Akiba from Freaklabs and Robin. Akiba designed the boards and worked with firmware; Robin did a lot of coding for computer and firmware.
