Re: Simple Arduino Pulse Rate Counter

I think just Arduinos's C++ syntax is extremly similar with Java's, and maybe therefore the confusion. But it is C++, even the first line of your program imports a C-header file that contains C function declarations ;) I'm not an expert, but I guess a JVM will also fill Arduino's memory several times.

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Thank you for your reply and analysis, Massimo. Yes, I may be wrong about the Pa-234m and then is all good. I noticed that about the saved spectra, but just didn't think about it when I took the pictures, since I was more concentrated in the energies, than the dose rate. Maybe still a bit of fine tu...

Re: Simple Arduino Pulse Rate Counter

Hi Steven,
Maybe you can use something like this, to shorten the summing of all these array elements:

Code: Select all

for(i=0; i<30; i++)
    {
        sum = sum + cps[i];
    }

Re: Simple Arduino Pulse Rate Counter

Yes, I know that about it, but thought the language is based on C not Java. Thanks Steven.

Re: Simple Arduino Pulse Rate Counter

Nice little counter indeed. Isn't the Arduino coded with some modified C++?

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

I can happily announce that I also became a part of the PDS-100G owners group few days ago. It's quite nice device, fast, sensitive and portable. Not cheap, but a good deal, especially having in mind the price for a new one of that type. Connected to a tablet it's really a very portable spectrometer...

Re: The Most Radioactive Room in My House

Nice job done again! And some equipment that made me a little jealous :)

Quack cure "Bio-energy" card with Th-232

A quack cure "Bio-energy" card, containing Th-232. It seems they put thorium not only in the "lava stone scalar energy pendant", but in this plastic Panacea too. It is also more active than I expected (~40 pps above background), clear spectrum is achieved in just few minutes. 1.jpg Description of th...

Re: Youtube Documentary

I've seen some video material from Carl Willis before, lots of interesting stuff there always. What really stands out is their passion about the things they are doing and so a scientist must be.

Interesting sample. How many CPS above background?
Just 1-2 cps above background (changes from ~10 to ~12 cps).
