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

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.

This is the project page for the Tokyo Hackerspace/RDTN Geiger project. This is an Arduino-based geiger counter shield that makes it easy to upload data to the internet and also interchange tubes. Since it's open source and Arduino-based, its also easy to hack this to other interesting applications.
Here's the dev history:

I just wanted to give a big thanks to Reuseum for sending us geiger counters on short notice. I'll be bringing them to the Tokyo Hackerspace meeting tomorrow and we'll get started on setting them up. I've powered both up, tested them outside, and confirmed that I'm able to sense geiger events. Now I just need to read the manual. He also sent us a nice keychain dosimeter and some "Atomic Fireball" candy. Ha ha ha. Much appreciated. We'll be sending back some genuine Japanese spinach :)
