Fresh hacks every day
This is a Geiger counter which charts its readings on a webpage. [Radu Motisan] put a lot of time into the build and it shows. This thing is packed with features and the hardware choices were the best combinations found through several iterations of development.
In addition to radiation levels the sensor unit takes several other measurements. These include … Read the rest
Have a little class when you’re screening for radioactive particles. You can follow the example which [Moustachenator] has set with this gorgeous Geiger counter case.
The business end includes the same Geiger tube we see in all of these projects, but he took the time to solder together a tidy circuit board and housed it in an acrylic … Read the rest
[Thomas] took a Geiger counter he built on a plane. Why? Because he can, much to the chagrin of airport security.
[Thomas]‘ Geiger counter is built around an old Russian SBT-10A detector containing ten separate Geiger tubes. This tube was connected to a circuit containing a LiPo battery, a few high-voltage components, and an audio jack connected to the … Read the rest
What do you do if you have 18 Geiger tubes lying around? [Robert] had an interesting idea to build a cosmic ray detector and hodoscope to observe the path cosmic rays take while flying through his lab.
[Robert]‘s cosmic ray detector works by detecting the output 9 Geiger tubes on the y-axis and 9 Geiger tubes on the x-axis with … Read the rest
[Jeff Keyser] from mightyohm.com got a chance to show off this interesting take on ambient music. He’s using his geiger counter kit to detect beta and gamma radiation. This then sends a pulse down the line to an Arduino to turn it into a musical note. The geiger counters put out a 1.ms 3v pulse though, so he first … Read the rest
It’s really amazing what you can find at military surplus shops. [David] just built a radiation detector out of a DT-590A scintillation probe originally made to test if Air Force bases were contaminated with Plutonium. Who says nothing good came out of massive nuclear arsenals?
DT-590A / PDR-56 Gamma ray probes were made obsolete by the US Air Force a … Read the rest
Next time you’re waiting in the security line in an airport, why don’t you pull out your smartphone and count all the radiation being emitted by those body scanners and x-rays? There’s an app for that, courtesy of Mr. [Rolf-Dieter Klein].
The app works by blocking all the light coming into a phone’s camera sensor with a piece of … Read the rest
