Arduino Mini Geiger Counter


by paulindallas @ instructables.com:

Last Black Friday, the big sale day that comes right after Thanksgiving, I came across a sale on the Electronic Goldmine web site for a Geiger counter kit and tube for about $30. Now I always wanted to play with a Geiger counter, even as a kid back in the 50’s when Uranium, nuclear power, mutant radioactive ants (the movie “THEM” 1954) etc. were all the rage. I figured I was not getting any younger, so I bought it.

Geiger counter with SBM20 tube


by weirdlab.fr:

I “rebuild” my Geiger counter, the SBM-20 tube was initially inside the box, i have put this one inside a 32mm diam plastic tube, for more convenience, wired through a XLR3 cable. This counter is from “Electronique-Pratique” n°368, a french electronic magazine. Shem, pcb, and PIC hex & C source code available.

Geiger Counter


A Geiger counter, also called a Geiger-Muller (GM) counter, is a type of particle detector that measures ionizing radiation. It detects the emission of nuclear radiation: alpha particles, beta particles, and gamma rays by the ionization produced in a low-pressure gas in a Geiger-Muller (GM) tube, which gives its name to the instrument.

A High Voltage generator (U1, U2, Q1, T1, and associated components) powers a GM tube. A pulse from the GM tube is interfaced through Q2 and U1 to pulse-generator U3, which drives a speaker.

Pocket Photodiode Geiger Counter


by JamecoElectronics @ instructables.com:

Build a DIY geiger counter that uses a PIN photodiode as a substitute for an expensive Geiger-Mueller tube. It detects alpha and beta radiation particles. The circuit is soldered onto a small protoboard and everything is placed in an aluminum enclosure. Copper tubing and a piece of aluminum foil is used to help filter out noise and RF interference.

Small, portable and cheap radiation detector is being designed for the public


By Ben Coxworth @ gizmag.com:

Ever since the Fukushima nuclear reactor disaster, there has understandably been an upsurge in the sale of consumer radiation-detecting devices. Most of these gadgets are variations on the Geiger counter, in that they alert the user to the presence and level of radiation, but not the type of radiation – which is very important to know. Researchers at Oregon State University are hoping to address that situation, with the MiniSpec. Currently in development, the handheld device will additionally tell its users what type of radionuclide is creating the radiation, and whether it poses a risk.

DIY Geiger counter


by Henrik’s Blog @ hforsten.com:

Ionizing radiation is something that almost anyone finds exciting (or scary) and I’ve also been for long wanted to build a Geiger counter. Unfortunately Geiger tubes have usually been too expensive to seriously consider buying them just for a hobby project. But I found out that sovtube sold soviet cold war era Geiger tubes only for a couple dollars. I bought one CI-22BG tube and one CI-3BG tube for total of 16€ including shipping from Ukraine to Finland. The site itself didn’t really convince me payment via Paypal failed because of invalid seller email address and gmail warned me that order confirmation e-mail might not have come from the address it claimed. However, I got both of the tubes and they seemed to be okay.

Wireless Monitoring Geiger Station

Radmon - inside and outside

sites.google.com/site/diygeigercounter writes:

This project measures the background radiation outside the house, and transmits it to a display station inside the house. The outside sensing unit is solar powered (but it doesn’t have to be), and should have a range of at least 50m. The display station inside the house continuously displays the current background, and logs it to an SD card (along with date / time, temperature and other data). Daily high counts and other information are also displayed.

ArduSat – Your Arduino Experiment in Space

Reka Kovacs writes:

We are building an ArduSat (according to the Cubesat standards a satellite 10 cm long at the edges and 1 kg or less), on this satellite we would put up to 5 Arduino’s and plug in 50+ sensors into them as well as 2 optical and 1 IR camera. Once the satellite is on orbit we would then give access to the general public/citizen scientists to the payload ( Arduinos, sensors and camera) to upload their own scientific experiments. We plan to capture the attention of the DIY community, hackers and makers, amateur astronomers and in general those interested in space exploration and the next frontier.

Sensor wise we have so far magnetometers, tachometers, plasma sensor, photometer, thermometer, pressure sensor, space radiation (bitflip) sensor, Geiger counter and 2 optical and 1 IR camera etc.The idea is that people can rent scientific packages for a week, during the week they run their experiment we will send data constantly back to them to analyze. Imagine general public, including teachers having access to experiment platform in space for a couple of hundreds of dollar and they analyze data and engage students, friends etc., it could revolutionize the way people see space. Also we are looking for feedback from people interested in the project. We want to hear their ideas or sensors and experiments!

GPS Geiger Counter Data Logger

John wrote in to show off his GPS/Geiger Counter Data Logger.

The enclosure is from Adafruit – about perfect, although it’s a pretty tight fit. The display is an OLED character display. (It’s a little quirky, and it draws more power than a regular LCD, but it’s really bright and clear.) The EM-406A GPS mounts on the top of the case. I drilled a small hole that shows the LED on the GPS module which lets me know when I have a fix. The IR detector is also on the top, so I can use a TV remote to set the parameters. The bottom has the on/off switch, (and now a piezo switch) and a slot that allows removal of the microSD card.
