Nice to hear. I'm the creator of Kitspace.org and I've spent a lot of time making the 1-click ordering work. It's an open source platform by the way: https://github.com/kitspace I'm far from an expert on this subject and am not sure if it…

The same PCB can be used to build an alpha spectrometer. This variant is a little harder to use correctly which is why we are not selling it as a kit yet. You can however use the links in the page to buy most of the required components…

…themselves are then identified by their steep slopes which shows up nicely in the derivatives: https://github.com/ozel/DIY_particle_detector/blob/90c180207...

…version of the Maxim one. And probably not so much worse in terms of signal to noise ratio: https://github.com/ozel/DIY_particle_detector/ The ion chambers are impressive because even lower-cost. But they also detect the presence of…

or one of those even cheaper 16bit USB soundcards https://github.com/ozel/DIY_particle_detector/wiki/Soundcard... I believe Steve (who wrote the blog) might have had the wrong cable for his other computer (3-pin vs. 4-pin 3.5 mm jack)

…detector[1] you see that the "sensor" can be a reverse biased diode. Nothing very fancy. [1] https://github.com/ozel/DIY_particle_detector

Let me just point here again to the project entries on Kitspace.org: https://kitspace.org/boards/github.com/ozel/diy_particle_det... https://kitspace.org/boards/github.com/ozel/diy_particle_det... Yes, this project is very much doable for…

Hey, project owner here. Glad you all enjoy this! :-) I've never built my particle detectors on a breadboard. It is extremely likely that they will oscillate or frustrate in another way. You have to keep in mind that the amplification is…

…If you look at the schematics they say you can use either through hole or SMD. SMD is preferred: https://github.com/ozel/DIY_particle_detector/blob/master/ha...

There seem to be builds using a through hole resistor for R3: https://github.com/ozel/DIY_particle_detector/blob/master/ha... The opamp appears to be configured as a transimpediance amplifier. 40M is a lot of gain. Probably keeping traces…

The GitHub project page has a better and more comprehensive introduction than the CERN page: * https://github.com/ozel/DIY_particle_detector/ Paper (Open Access, click "Download PDF"): * Smartphone and Tablet-Based Sensing of Environmental…
