Global Thermonuclear War: Tweeted

[Andreas Spiess] did a video earlier this year about fallout shelters. So it makes sense now he’s interested in having a Geiger counter connected to the network. He married a prefabricated counter with an ESP32. If it were just that simple, it wouldn’t be very remarkable, but [Andreas] also reverse-engineered the schematic for the counter and discusses the theory of operation, too. You can see the full video, below.

We often think we don’t need a network-connected soldering iron or toaster. However, if you have a radiological event, getting a cell phone alert might actually be useful. Of course, if …read more

Fun-Size Geiger Counter Sits atop a 9-Volt Battery

Want a little heads-up before walking into a potentially dangerous radioactive area? Sure, we all do. But the typical surplus Civil Defense Geiger counter is just too bulky to fit into the sleek, modern every-day carry of the smartphone age. So why not slim down your first line of defense against achieving mutant status with this tiny Geiger counter (Facebook)?

We jest about the use cases for a personal-sized Geiger counter, as [Ian King]’s inspiration for this miniaturized build was based more on a fascination with quantifying the unseen world around us. Details are thin in his post, but [Ian] …read more

Mood Lamp Also Warns of Nuclear Catastrophe

[Michal Zalewski] has radiation on the brain. Why else would he gut a perfectly-horrible floor lamp, rebuild the entire thing with high-power RGB LEDs, and then drive it with a microcontroller that is connected up to a Geiger-Müller tube? Oh right, because it also looks very cool, and Geiger tubes are awesome.

If you’ve been putting off your own Geiger tube project, and we know you have, [Michal]’s detailed explanation of the driver circuit and building one from scratch should help get you off the couch. Since a Geiger tube needs 400 volts DC, some precautions are necessary here, and …read more

Roam the Wastelands with this Fallout-Themed Mini Geiger Counter

For anyone who has worked with radioactive materials, there’s something that’s oddly comforting about the random clicks of a Geiger counter. And those comforting clicks are exactly why we like this simple pocket Geiger counter.

Another good reason to like [Tim]’s build is the Fallout theme of the case. While not an item from the game, the aesthetic he went for with the 3D-printed case certainly matches the Fallout universe. The counter itself is based on the popular Russian SBT-11A G-M tubes that are floating around eBay these days. You might recall them from coverage of this minimalist Geiger counter, …read more

A No-Solder, Scrap-Bin Geiger Counter for $15

Scenario: your little three-hour boat tour runs into a storm, and you’re shipwrecked on a tropic island paradise. You’re pretty sure your new home was once a nuclear test site, but you have no way to check. Only your scrap bin, camera bag, and hot glue gun survived the wreck. Can you put together a Geiger-Müller counter from scrap and save the day?

Probably not, unless your scrap bin is unusually well stocked and contains a surplus Russian SI-3BG miniature Geiger tube, the heart of [GH]’s desert island build. These tubes need around 400 volts across them for incident beta …read more
