bGeigie Ninja, a new and improved bGeigie

NetRAD based bGeige Ninja

The original bGeigie design dictated that a self contained radiation sensor would be attached to a laptop and a GPS device and data would be logged and recorded through that. This system worked but required a lot of hardware. At Tokyo Hackerspace, Akiba has been working on his own sensor board design for his company Freaklabs. This design has onboard GPS and saves data directly to an SD card eliminating the need for an external laptop or location device. Pieter has built a few of these into self contained, self powered devices that are being referred to as bGeigie Ninjas. Here’s a few photos of these being put together.
