Re: Simple Arduino Pulse Rate Counter

Svilen, The Arduino coding language is a form of Java, you download the free editor and it comes with a stack of examples that you can open and modify for your own purpose. When you add on devices such as displays, you need to import a "Library" which is basically just some hidden code specific to t...

Simple Arduino Pulse Rate Counter

Hi Guys, Some of you might be interested in this project.. I'm sending one of my Neutron detectors over to ANSTO (Australian Nuclear Science and Technology Organisation) for calibration and so they don't have to mess around with sound card software (my guess is they are hardcore NIM people), I quick...

Re: I am back

Hi Fer,

Great to see you back..., I can't believe you have GS-1100A (0024), that was one of the very first boards I made, is it still working? The GS has gone through many versions since then, and I am now up to serial numbers #1290.

Look forward to read more about your experiments.

Re: Greeting from Canada... HELP!

Raphael, If the detector has a low impedance divider the voltage on the BNC will be less than the setting, because the GS is calibrated with a 1G ohm load. If your divider is 10M and the load resistor in the GS is 1M then the total divider is 11M, so your voltage will be; 700V * (10/11) = 636 Volts....

Re: Greeting from Canada... HELP!

Hi Raphael, First of all, welcome to the forum and thanks for the introduction. Due to recent spamming of the forum I am manually approving the first three posts, but after that your posts are automatically approved. You are very ambitious taking on Becqmoni on your first attempt, the software has n...

Schmitt Trigger Circuit

Hi All, Not sure if any of you do any neutron counting, but if so this might be of interest. I have developed a new circuit for the Russian neutron counters. Lot's of people have bought these tubes on eBay and not been able to make them work, that's because they don't operate like other proportional...

Linking to images on remote servers

Hi All, One of our members has brought it to my attention that images hosted on a remote server will not show on this forum unless the site also runs https protocol, this makes sense, but may not be immediately obvious. Other disadvantages of linking to remote sites are when those sites go down, so ...

Re: Cs-137 contamination in Austria

Milos,

Thanks for sharing, it does indeed look like a very beautiful spot, and maybe not so surprising if fallout has accumulated in the silt as water washes it down the mountain. Archeologists in the future will be able to date their core samples to the exact year.
