      ahha... trrs cable required...

    2. Creator Stanford Siver on December 31, 2013

      connecting iphone to kickstarter/onyx with audio cable... but app isn't picking up the clicks. what to do? have a link to documentation?

    3. Creator Rolf-Dieter Klein on May 16, 2013

      Just got it by fedex -- real great device ! congratulation.

    4. Creator Leon Muller on May 7, 2013

      Hi lord_yo. I checked my box yesterday and can confirm they shipped them out of the US via the US Postal Service.

    5. Creator lord_yo on May 1, 2013

      Thanks, Leon, what a relief!

    6. Creator Leon Muller on May 1, 2013

      When mine was sent to Australia it was delivered by Australia post. I can check the box for you when I get home but it seemed to be just domestic post ; so I'm guessing USPS since it shipped out of the US.

    7. Creator lord_yo on April 30, 2013

      Can you tell us how the Onyx will be shipped internationally (i.e. which carrier - USPS, FedEx etc.)? I'm asking because my address contains a P.O. Box which a non-postal carrier such as FedEx will have trouble delivering to.

    8. Creator Sean Bonner on April 20, 2013

      No it's not, we licensed a modified version of GeigerBot since Nick had done such an amazing job with that already.

    9. Creator I Heart Engineering (deleted) on April 20, 2013

      Is the source for the iPhone app available somewhere?

    10. Creator I Heart Engineering (deleted) on April 20, 2013

      We have a pull request for USB serial interface documentation

    11. Creator Jerry Isdale on April 12, 2013

      Received mine in Maui earlier this week and have been driving around with it. Generally getting between 17 and 35 CPM. Not sure how to get the data out of this device. I went online and downloaded the Mac OSX application (Onyx Loader) but it doesn't seem to do anything useful.
      Now what?

    12. Creator Bill Hemphill on April 12, 2013

      Onyx #081 of 263—Received, working and beeping away (but not too furiously). Sweet, clean design; very nice presentation; good heft: the design work and craftsmanship is apparent. Thanks! Now, if someone would just be so kind as to post a Beta version of a manual (or a link by E-mail), we can really start playing with this new toy...for SCIENCE! An Android interface/app would be most excellent... but we understand.

    13. Creator Jeff M. on April 10, 2013

      Just a quick update, Sean responded back to me and on the forum that trrs cable is needed (4 conductor) for iPhone interface. I picked one up and receving data now. The scale is off on the iPhone, so I need to figure that out next... The Onyx is a very cool device!

    14. Creator Jeff M. on April 8, 2013

      I received mine today as well! I am trying to get it working with my iPhone with little success so far. The manual has not been posted online yet. The Safe Cast app will not save IMI Onyx as a device after I select it from the settings. I tried the 3.5mm patch cable from Radio Shack and cannot get it to work. The online manual for Safe Cast iPhone app says to turn on AGC if counts are not picked up, but I cannot find that setting.

      Anyone else had any luck getting the patch cable working with the iPhone?

    15. Creator The Captain on April 8, 2013

      Got mine - no. 68 - as well. Works great, easy to use, radiation has never been so fun. I just wish we could hear old school clicks instead of beeps. House hot-zone: my natural gas fireplace.

    16. Creator Chuck Pearce on April 8, 2013

      Just to let anyone know checking the comments section, I received mine in the South East USA today #66 of #263!

    17. Creator Larry Garetto on April 4, 2013

      Is there going to be any tracking info once they are shipped?

    18. Creator Sean Bonner on March 21, 2013

      Not yet, they are shipping out one at a time as we're doing a lot of quality control and last second checks on each one. I'll post a new update soon but they should all be shipped out within the next 2 weeks, but some people have already received them...

    19. Creator Chuck Pearce on March 21, 2013

      Can't wait, any word it all units have been shipped?

    20. Creator james steele on March 3, 2013

      Is there a pc option? or only iOS support? will an ipad touch work?

    21. Creator Sean Bonner on March 2, 2013

      At this point no. If you know any Android developers who want to work on it we'd love to talk to them but unfortunately we've had a lot of volunteers but nothing fruitful has come yet.

    22. Creator james steele on March 2, 2013

      yea android here too...

    23. Creator Larry Garetto on March 2, 2013

      I'm sure it was answered somewhere but I haven't seen it. Is there going to be an android app?

    24. Creator Steven Sporen on February 23, 2013

      Hi Sean,

      looking for some help on the api's for the safe cast data, they seem to be broken and I am not sure to talk to. Could you pass on the info?


    25. Creator Leon Muller on January 15, 2013

      Perfect, no problems Sean. Good luck with the hackathon.

    26. Creator Sean Bonner on January 15, 2013

      Hey Leon - We don't get address info from Amazon and haven't collected it from backers yet, we're waiting until the minute before we're about to ship so that we'll have the most up to date info for everyone.

    27. Creator Leon Muller on January 15, 2013

      Thanks for the updates. As I'll be moving house within the next two weeks I was wondering if they will be posted to the address provided during the original checkout process (I think Amazon payments collected an address) or if we'll have to supply an address via Email? Thanks.

    28. Creator James Petts on December 15, 2012

      Can we get an update, please?

    29. Creator Jerome Poichet on December 1, 2012

      I know it's only the first of December but when should we expect receiving those? I have an upcoming trip to Japan and was hoping to have it by then.

    30. Creator Sean Bonner on November 15, 2012

      Ted - it will actually fit in any of them I believe though it's not designed specifically for any particular model. I guess it would depend if you were putting anything else in the case with it? FWIW these seem to fit in any flexible case that will hold an iPhone.

    31. Creator ted on November 14, 2012

      What size Pelican case do you suggest for transport and storage?

    32. Creator machine idea g on October 26, 2012

      Partly read update. Suggest strongly not to use Onyx as this is name of probably the most respected and longest lived line of finger pulse oximeters (by Nonin).. Many medical, nursing staff and EMTs and respiratory techs use one of the various models.
      Maybe pick another crystal or stone? There are so many of them.
      Thanks for keeping us updated.
      regards from

    33. Creator Sean Bonner on October 5, 2012

      Hey Ted - yep, still on schedule! Apps already available and more coming soon. The device is just a geiger counter so it's no more "compatible" with any network than anything else, but as we (safecast) designed it to incredibly high standards there's no reason it shouldn't be. The apps we've been developing work specifically with Safecast, but all Safecast data is open so...

    34. Creator ted on October 5, 2012

      I'm getting excited. November will be here faster that you know it. Are the devices still on schedule to be delivered next month?

      Will there be programs and apps available to make uploading data easy?

      Will these devices be compatible with RadiationNetwork & Blackcatsystems?

    35. Creator Jerry Isdale on July 17, 2012

      Driving cross usa w bGeigie radiation recorder from currently reads 0.105 uSh, micro seiverts per hour I think. Max so far was in Holland tunnel nyc/nj at 0.4uSh stay tooned to me on fbook, Twitter g+ for updates— at i80 eastern pennsylvanian.
      I will upload records to safecast when I can.

    36. Creator Sean Bonner on June 19, 2012

      Thanks Chuck!
      We really sold these incredibly close to cost, so once shipping and whatever else is rolled in this will likely just be for the devices and won't leave anything for Safecast as an organization, that said getting the data back from this will be even better for us than a few hundred bucks and especially ongoing, which be a much larger support for our efforts. So the publicity this brought and the data we'll get makes this a huge score for Safecast, regardless of any $$$

    37. Creator Chuck Pearce on June 19, 2012

      Wow... just wow... over 100,000 amazing. Sean you and your team really deserve a round of applause. Any chance a bit of the funds contributed by the backers getting the Safecast X go to the Safecast foundation? Or are they going 100% to the manufacturer?

    38. Creator Sean Bonner on June 19, 2012

      Hi lord_yo-
      1: Yes, it measures all three, the way to differentiate is externally via shielding the sensor.
      2: Depending on where you live there are lots of options - fiestaware plates, bananas, smoke detectors... plenty of radioactive items around to try out.

    39. Creator lord_yo on June 19, 2012

      Two questions:

      1) If I understand correctly, the device measures alpha, beta and gamma radiation. Does it differentiate between the three, or are they lumped together as one value?

      2) What would you recommend: What's the best way to test a Geiger counter (apart from measuring background radiation)?

    40. Creator Sean Bonner on June 18, 2012

      Hi Ted- Not sure how Medcom will be shipping these devices, though I'd imagine they will ship them the same way they ship all their radiation sensors. There's no issue with pressure in shipping that we've seen.

    41. Creator ted on June 18, 2012

      How will these be shipped in the USA?

      When you ship internationally, will each unit be packed in a way to protect it from pressure?

    42. Creator Pieter Franken on June 17, 2012

      Hi Sonia, yes our device will be able to detect people that are undergoing radio therapy as the levels emitted can be quite high (up to a couple of uSv/hr in near vicinity). It has happened to myself when walking in Tokyo with a similar sensitive device that the alarm goes off when passing by a person that is under treatment. However , it is difficult to measure people that have been exposed to much smaller doses as is the case in Fukushima, without much more sensitive equipment and extensive shielding of the room the measurement is done. Hope that helps!

    43. Creator Sonia Koval on June 17, 2012

      Hi again. Actually the I-131 patient *is* emitting radiation -- having not merely been exposed to radiation (e.g. external beam or some sort of accident) but actually ingested it (in liquid form or a pill -- "don't touch it, just swallow it!" ). Thus the list of radiation safety precautions to protect others (time & distance -- especially important wrt children & pregnant women -- and care with bodily fluids which excrete the radiation) and often a letter to "Security Officials" in case of setting off a radiation detector, which can happen (has happened) many weeks after treatment. So I wondered if your machine would read anything off one of these patients.

    44. Creator Sean Bonner on June 17, 2012

      Hi Chuck- Yes, it's very similar - the water in the food is part of the problem, and yes there's no simple handheld solution. We've looked into it, and continue to be hopeful but haven't found a solution at this point.

    45. Creator Chuck Pearce on June 17, 2012

      Sean, is the measuring of the body similar to that of measuring food in terms of complexity? I ask because I know measuring food is one of the major concerns for the people of Japan and to my knowledge no handheld products exist to facilitate this, however I believe I read in comments or faq about your team researching a food measuring device. Please correct me if I misread.

    46. Creator Sean Bonner on June 17, 2012

      Hi Sonia-
      No, unfortunately not, it's very difficult to measure people and requires a large area (a whole room) that has been removed of all background radiation.That said, because of the amount of water in the human body, which blocks radiation, even if someone has been exposed that doesn't mean they emit anything - they might just be radiating themselves.

    47. Creator Sonia Koval on June 17, 2012

      Tossing in a couple of bucks just to get in on the conversation (some tiny bits of which I actually understand :-)).

      I'm wondering if this gizmo would be useful or usable (or just plain provide "interesting information") to find out how much radiation an actual person is emitting (or the "air around them"? contains) after ingesting I-131 (treatment for thyroid cancer). I know the hospital RSO measures you before you're released (with a list of radiation safety precautions!) but of course they have really good equipment for it. Then there's whatever the "hot" patient comes in contact with (esp. coughing & sneezing, eating utensils, not to mention the toilet/contents) that could get hot-by-association.

      Like I said, just wondering. I don't actually understand much of this stuff!

    48. Creator Edouard Lafargue on June 17, 2012

      @Alex Weyermann: looking at the schematics, it certainly looks like P101, which is a serial header, could be used as an accessory port. Is it already allocated for a specific use?
