There’s no shortage of Geiger counter projects based on the old Soviet SBM-20 tube, it’s a classic circuit that’s easy enough even for a beginner to implement — so long …read more Continue reading ESP32 Brings New Features To Classic Geiger Circuit
It is a time-honored tradition: buy some cheap piece of gear and rewrite the firmware to make it work better. [Gissio] managed to do just that for a cheap FS2011 …read more Continue reading An Open Source Firmware for Cheap Geiger Counters
It used to be that every well-stocked doomsday bunker had a Geiger counter. These days, you don’t have to have a big tube-based meter. You can inexpensively get a compact …read more Continue reading Detecting Radiation for Fun and Profit
Over the years we’ve covered many projects aimed at detecting elevated radiation levels, and a fair number of them have been Internet connected in some way. But as they are …read more Continue reading ESP32 Powers Fresh Take On An IoT Geiger Counter
Do you have anything radioactive in your house? Most people will say no, but they are probably wrong. A host of things ranging from glow-in-the dark timepieces to smoke detectors …read more Continue reading Is Your Tape Dispenser Radioactive?
Old Civil Defense survey meters like the V-715 are interesting conversation starters, but of very little practical use today. These devices were intended to be a sort of litmus test that survivors of a nuclear blast could use to determine …read more
If you like it when a hack has a little backstory, then you’re going to love this cyberdeck build log, the first half of which reads like a [Tom Clancy] novel. And the build itself looks the part, like something that fell off a military helicopter as the Special Forces …read more

With all the focus on biological problems, we might forget that sometimes it’s handy to know about radiation hazards, too. [Ryan Harrington] shows us how to make a Geiger counter with very few parts, and you can see the results in the video below.
The glut of surplus Russian tubes …read more
It took nearly a year for [Chris Crocker-White] to assemble this glorious mahogany and brass Geiger counter, but we think you’ll agree with us that it was time well spent. From the servo-actuated counter to the Nixie tubes and LED faux-decatrons, this project is an absolute love letter to antiquated …read more

[Nick Price] had a wonderful concept for a DEFCON badge: a device that worked a lot like a directional Geiger counter, but chirped at detecting WiFi deauthentication packets instead of radiation. That’s a wild idea and it somehow slipped past us last year. Why detect such a thing? Well, the …read more
