![]() My only advice is that you consider the differences. Should you buy a clone? Of course that's up to you. Have you been reading "Sour Grapes" ? Honestly, not really - that's just the way it is. If you want to see a fun video on this subject check out EEVblog #333 - Unwritten Rules of OSHW. These, I call "knock-offs" or more politely "clones". However, there are some who apparently just want to "cash in" by taking the design, software, hardware and even the documentation and the name, and adding little if anything to the project. Of course there were some who just wanted to sell a kit, and I expected they would build on my ideas by adding their own ideas and create something new and different. I did this thinking that people who wanted to build their own could reference what I have. If "imitation is the sincerest form of flattery" then I am truly flattered! But I should first define what I call a knock-off (clone is another word).įrom the beginning, the software I've written for the kit is open source, and the circuit is thoroughly defined. All have all pins broken out and an FTDI connector that will allow it to be programmed with the Arduino IDE if desired. The GK-Plus kit uses a larger ATmega1284P. The GK-B5 and GK-Mini kits use an ATmega328P. For a list of tubes that have been successfully used with the kit, see GM Tube Info. The kits will work with GM tubes that require high voltage in the range of 350-940V (which is most tubes.). However, with these simple additions the kits are a fully functioning Geiger counter. They do not include a GM tube, battery, case and controls that you may wish to put on a case. Geiger Kits are not an "instant Geiger counter" ready for field use. Counts can also be output to a PC via a serial connection.Īssembly requires moderately good soldering skills, and the ability to read and follow the Build Instructions supplied. The events are counted and displayed as CPM and dose rate by a microprocessor running preloaded software. These kits provide the electronics needed to run, and detect events from a GM tube. Since then there have been severial models and many improvements. It was one of the first Geiger counter kits available. The goal was to have a low cost solution for the sudden interest in radiation detection. The first "DIY Geiger Kits" were produced in 2011, shortly after the Fukushima disaster. ![]()
