Hi, I’m Trevor Nestor. On this episode of my show, Trevor Nestor’s Lab, I construct a Geiger counter from a hacked disposable camera.

See my Instructable for the project here.

    Less clown and more what why where how, please. There once was a Boy Scout merit badge for building a geiger counter. The radioactive material used to demonstrate its successful functionality was the Thorium(?) lamp wick for camper lamps. I’d like to see that badge revived.
    What are you using for radioactive test material?
    How do you amplify the signal?
    How do you convert signal to sound?
    Why remove the large capacitor?
    Why not flip the pcb so we can see what your four wires are connected to?
    The camera’s oscillator and step up transformer produce high voltage, so why not discuss this and point to its output, and discuss how the output, ie, the gap probes, serve also as the input of the click signal, and Hey! Once more: What part of the PCB is amplifying THAT signal???

      I agree, this video generates frustration and as a consequence only the few who know more than Mr Trevor will venture on making one. This is more trash than science.

  2. Dude, you can’t speak too technically to the general population, otherwise you attract only a specific demographic

  3. Clearly many people did like the video, and I was given two awards on instructables.com for it. I guess you can’t please everyone though.

    It’s not working that well for me. It arcs whenever i make the electrodes touch, but other than that no matter how close i get it it won’t even pick up background radiation. I also tried putting it near my smoke detector and try my uranium glass, and i got nothing.
