Hobby electronics, microcontroller, quadcopter, sensors. Nanoflyer updates after a long break. Nanoflyer updates after a long break. August 8, 2013. I have been busy for a while with various things. At the same time I was desinging the prototypes for the nanoflyer board to fit in a hubsan quadcopter frame, as well as designing the board for the miniTx transmitter. I finally got some time to get those assembled and test it out. 1 Atmega128rfa1 2.4GHz transceiver 8-bit MCU. 2 MPU9150 Acc/Gyro/Mag sensor.

Gamma activity measurements of Tokyo-area soil samples | Special Nuclear Material
https://carlwillis.wordpress.com/2011/11/04/gamma-activity-measurements-of-tokyo-area-soil-samples
A Carl Willis Joint. Laquo; Trick or Treat! US Radium, Then and Now. Gamma activity measurements of Tokyo-area soil samples. November 4, 2011. Three nuclear reactors melted down. But even densely-populated Tokyo, some 150 miles distant, received significant fallout. Last month, I received a set of six soil samples from the Tokyo region, and, using my HPGe gamma detector. I have attempted a quantitative analysis of the two predominant gamma activities in these samples, Cs-137 and Cs-134. Sample 2: Garden ...

HPGe Detector, Part I: Repair | Special Nuclear Material
https://carlwillis.wordpress.com/2011/09/16/hpge-detector-part-i-repair
A Carl Willis Joint. Laquo; Visiting Vogtle and Bellefonte Nuclear Power Plants. Videos from my recent trip to Chernobyl. HPGe Detector, Part I: Repair. September 16, 2011. A high-purity germanium (HPGe). Is the ultimate instrument for energy spectrometry of gamma radiation. For the nuclear hobbyist, an HPGe opens a window into a fascinating realm of home-accessible, low-intensity nuclear reactions that are obscured by background in other detectors lacking the superlative resolution . 8212;the thing work...
