- This thing looks pretty steampunk!

This isn't the same electromechanical counter that I used, but it would still work.

I admire your reaction to things that go wrong. I wish I could have the strength to do that more often.
11:27 awesome sound :D
You may use some counter IC like for example 4060 and divide the number of pulses, so that you will be able to use the mechanical counter even at much higher count rates. It would be also interesting to find out the "dead time" of the mechanical counter. You could then calculate at what rate you should divide the count rate by bigger number.
Cool, I like you,
you get better as time goes on, keep on youtubbing.
Higher than avg. national background:
Search for Radon sources near your village/city. Check out if airing your room will decrease the background, longer measurements needed in order to make sure.
Also radioactive sources may generate some radon aswell. I've seen a source on your workbench, so yeah that is that.
Also, try to use a small boost converter to generate the right voltage for the tube. Basically that stuff doesn't draw current. So a small coil of 3 or 4 millihenries and a switching MOSFET with an 555 driver stage should get you a decent voltage. And it would be more ergonomic to handle.
Was the diode really shorted? I suspect you put it in the wrong way ;).BTW, one question: Where did you get your wall mounted component shelves from? On Amazon they are quiet expensive, maybe you can tell me another source?ThanksLutz
Genius!
Tanner, help this old man here, me. Lol. I sen you message on your car on race track video, asking for clarification on sensors and obstacle avoidance from your knowledge base. Thanks!
Those electromechanical counters are so expensive!
They are typically, but I found mine for around 3 dollars a piece I think.
@@TannerTech I’m finding some reak cheap ones on ebay - and some old soviet ones! The latter ought to be interesting for a geiger counter build
nice to see it done without the use of a micro :)
I need to build one of these. Something about it I really like. I'd love to see what would happen if I put my 35kcpm source next to it.
Could you have just used the signal of a count as a square wave, to trigger a transistor and just supply more power in order to turn the counter
Hey Tanner, really great videos!!! What is the input voltage of the counter, how much is required to drive it? and one last question, on the geiger counter circuit, what is the output "pulse" pin voltage? 3 ~ 5 V?
Yep, that pulse pin should give a logic output signal. I think I used around 300-400 volts to drive it. Good luck building one!
Hi taner ı am from turkey and me to do same projects ı like your videos keep going 👍👊
Where is the intro?
Come home soon!
Would it really go through the diode? It has two available paths 😛
Deeeeeeep voice 😅
I think your previous calculations were a little off, but who am I to argue
So if you increase the time per click, say its 4 times longer than original, aren't you going to miss 75% of the total count?
I can understand from skimming through the video (and with the help of your remark) that the ne555 will increase the pulse duration to run the electro mechanic counter, yes I also think that the time it takes to turn the mechanical roulette by one you will reluctantly ignore other pulses generated by the Geiger tube.
yet it was a simple circuit and nice proof of concept ✔👍
Quee-ess-ant 😉
