This is a full day of work for members of Safecast to plan out the next gen designs and get shit done. We will only be using the work area so a workshop can also occur in tandem if needed. An agenda will be posted soon.

Safecast will be building radiation sensors at Tokyo Hackerspace for deployment around Fukushima prefecture. This will mostly consist of soldering, drilling, and cutting. These radiation sensors also generate money for Tokyo Hackerspace to purchase equipment for workshops. If you have some free time and want to volunteer, drop on by. Akiba will be there from 1 pm to 5 pm.

This is a private event where we build devices for radiation sensors at Tokyo Hackerspace. We'll only be using one side of the space so the non-work side can also be used. We'll be occupying the area for the following areas:

- Friday: 7pm-11 pm
- Saturday: 12pm-5pm (if not conflicting with felters)
- Sunday: 12pm-5pm

The 2nd-in-a-row class will be held at THS house, as usual on August 22nd, 19:30-22:30: http://www.tokyohackerspace.org/en/book/how-to-get-there

See this for more insights on the history of this kit:

This kit is a THS[1] project in collaboration with SafeCast[2]. Once you buy and build your device, you own it (hardware and software) and the data it produces. You can opt-in to have your data logged to the THS account on Pachube[3] (for free) and have it available to the public (for free).

I am planing to organize a DIY GM counter workshop. Details are still not fixed, stay tuned.

DIYガイガーカウンターのワークショップを予定しています。詳細はまだ検討中です。そのうち、日本語のページもアップします。

The kit consist of 3 parts: motherboard (Freakduino), daugtherboard (NetRAD shield) and radiation sensor (SBM-20 GM tube). If you have any of these, you can use yours, but we'll have to make sure they are similar enough.

We've got lots of requests about how to build geiger counters, but want some teachers to do classes outside of Tokyo. Looking for:

- people with electronics experience
- people who can go to Sendai or Fukushima

This class is members only and will only be open to people that sign up.

You can choose to only purchase the materials you're interested in building. However you will need to learn how the other components are built. You can also just observe if you do not want to pay for materials. The cost of the materials will be:

- 4000 yen for the NetRAD board

Pieter and I went to MIT Media Lab to attend the Safecast meetup and discuss the radiation mapping project. Along with meeting everyone involved in Safecast on the US side, we got the chance to hang out at the High/Low Tech lab with Leah Buechley. Leah was the designer of the LilyPad Arduino and also works on craft-oriented applications of technology. I was struck by the similarities of hearing her talk and listening to Mitch Altman talk. One of the other things I was impressed with is that the supply jars in the High/Low tech lab don't have the usual things like screws or parts.

Things have been crazy in Tokyo Hackerspace recently. There are tons of projects going on simultaneously and everyone is buzzing about. We've been hosting a lot of guest speakers at the hackerspace as well to provide updates on what's going on, what they're up to, and to provide information about the recent events.
