Conrad Farnsworth originally from Wyoming made headlines back in 2011 when, as a 17 year old, he built a nuclear fusion reactor in his garage and posted the process in a YouTube video.?? Since then, he has graduated high school and gone onto study electrical engineering at the South Dakota School of Mines and Technology in Rapid City, South Dakota.? And, on the side, he runs a company called?Farnsworth Downs Technology?that manufactures molten salt reactors. ?On the side of that, Farnsworth designs 3D printable Geiger counters.

What is a Geiger counter? A Gieger counter is a?device that is used to detect ionizing radiation and radioactivity, with some models detecting Alpha and Beta radiation and others detecting X-rays and Gamma rays. The device gets a reading on the levels of radiation and then displays a reading on an digital or analog LCD screen. The reading itself is given in counts or in radiation doses, with counts being simpler to read and understand. Generally with Geiger counters, there is an option to have audible clicks giving the reader an idea of how strong the radiation being detected is.

Farnsworth’s model blends mostly 3D printed parts with a few electronic pieces from SparkFun, an online electronic project retailer. He used a Geiger counter board, a 3.7v boost converter switch, a 3.7v lithium ion battery and a microview from SparkFun. Everything else is 3D printed, with all of the files available on Thingiverse. According to Farnsworth, it took just 24 hours to design and build this machine, using SolidWorks for the design and an Ultimaker 2 to print out the six 3D printed parts.

If your prepping to survive in the ruins of a post-nuclear landscape, your own 21st century nuclear disaster area, or are just curious about the radioactivity of things, this project might be for you.? And it’s definitely a useful tool for anyone building a nuclear reactor in their garage.

年轻的核物理学家利用3D打印配件组建的盖革－米勒计数器

康拉德·法恩斯沃思最初是从怀俄明州的头条新闻回顾2011年的时候，作为一个17岁，他建立了一个核聚变反应堆在他的车库和发布过程中的YouTube视频。??此后，他曾在矿业和技术的南达科他州学校拉皮德城，南达科他高中毕业到了学习电子工程。？而且，就在旁边，他经营着一家叫什么名字？法恩斯沃思唐斯技术？是生产熔盐反应堆。 ？最重要的是侧面，法恩斯沃思设计3D打印的盖革计数器。

什么是盖革计数器？甲Gieger计数器是？是，用于检测电离辐射和放射性，在某些机型检测α和β射线和其他检测X射线和γ射线的设备。该设备获得在辐射的电平的读出，然后显示在一个数字或模拟的液晶屏的读出。读数本身是由于在数量还是在辐射剂量与数量是易于阅读和理解。一般用盖革计数器，有一个选项，点击发声给读者的有多强被检测到的辐射是一个想法。

法恩斯沃思模型融合大多是3D打印的部件有几件电子从SparkFun，网上电子工程零售商。他用盖革计数器板，3.7V升压转换器开关，3.7V的锂离子电池，并从SparkFun一个微视。一切是3D打印的所有文件，可在Thingiverse。据法恩斯沃思，只花了24小时，设计和建造这台机器，使用SolidWorks的设计和Ultimaker2，打印出的六个3D打印的部件。

如果你要预学习在后核的风景，你自己的21世纪的核灾区的废墟存活或只是好奇的东西的放射性，这个项目可能是你？而且这绝对是任何人建造一个核反应堆在他们的车库一个有用的工具。
