@ Architect, like lightning perhaps? 
yeah, that is the one too 
Got any iodine-131, cesium-137, cobalt-60, radium-226, or technetium-99m kicking around? Got any old glow in the dark watch faces around as those contained radium and your Americium smoke detector is a low source of gamma so if your able to pickup some gamma off of that then really that is a positive indicator.
Iād send you some samples from the reactor we have in the lab, but apparently DHS type people tend to get excited about that.
Iāve often wondered about these:
Simple hire Lee Trevino send him out to the tee box with a 1-iron and stand back.
Even this:
But somehow I assume that they donāt ship outside the USAā¦
I must still order some vaseline glass from ebay, for my testing, but I would also like to include a piece with every order for the user to play with.
I will order one, please count me. Thanks.
Iāll be building 9 so I think there will be enough thus farā¦
Ok, now I need a piezo module. 
How can there still be no piezo module?
What is a geiger counter that doesnāt tick?
Using an e-block piezo with the eblock expantion module is very bulkyā¦
BTW, this counter will probably only count upto 1000 counts per second, or 60000 counts per minute, as I feed the pulse directly to the interrupt pin. Does anybody think that this will be a problem?
I must also still measure the current, for which I must assemble my module current measurement module.
I guess there are many people hoping the answer to this is NO otherwise thereās a lot of radiation where we wouldnāt expect !! (actually I have no idea if 1000/sec is excessive, it sounds it though 
)
Whereās our custom DL firmware guy. Might be a good use of a DL40 hardware counter?
āHow can there still be no piezo module?ā
I donāt like piezo, if you test it at office or home , the sound of piezo may make someone craze.
So your thinking of including a piece of this with every module or something like it?
Certainly put me down for a module when they are ready.
I would agree that you should be able to shut off the sound. How I hope to be able to use this is to have the reading digitally so I can upload it to COSM, ThingSpeak or some other site (perhaps even http://radiationnetwork.com/ ) in real time.
Click rates and their meaning vary per device, for example as mentioned at radiationnetwork.com
so a 1000 CPM on a Mueller tube could very well indicate that perhaps its a good time to see what the heck is going on.
Yeah, I asked that seller earlier this morning if it is actually radioactive. You never know with these ācreativeā ebay sellers.
My unit should be good up to 1000cps, in other words 60000cpm.
Iām not including a speaker of any kind. My current setup has the NETMF board produce a ātickā everytime is gets a signal from the module. But it would be nice to have a piezo module to connect to the NETMF board so it can make a soundā¦
@ GMod(Errol) - Iāll send @ Duke a buzzer incase he picks up one of your modules to play with 
@ GMod(Errol) - GHI now has PWM buzzer module.
@ Architect - And itās a funky looking thing too
Yeah SMT buzzer is unusual.
Ahh, preview, that is why I didnāt see itā¦
It will improve the layout of my project thoughā¦
Nice to see it in comparison with the Cerberus.
That is an awesomely good looking module.
I checked our Depression Glass and heck ya its authentic Depression Glass, complete with that nice Green Fluorescence under UV light, so apparently I have samples ready to test here.
If you have any Bananas, you might want to test them.
Thats a nice looking module. I had thought about making one but 500v scared me off. I just know i would slip and loose a finger tip.
