      Has the assembled apoc basics been sent out yet, from the uk here and haven't recieved it yet if it has?

    2. Thomas G on December 19, 2013

      I meant that I have not received the Advanced replacement option of Advanced: 1 assembled APOC Basic, 1 APOC Basic Kit, and a $20 refund via PayPal.


    3. Thomas G on December 19, 2013

      I pledged for the APOC ADVANCED but I see from the update that it was not possible to make that work. I filled out the survey for the replacement option but have not received the Super Combo. Any news on shipping these ?

      I know you were trying for a compact design but had you considered a Dumbbell shell design where the BT would be a distance away from the detector to keep the interference down ?

      If anyone needs someone to build their basic kit for them, I have built three of them successfully.

      I will charge $25 for assembly to include tracked first class shipping in the USA BOTH ways (as long as you have a printer to print the shipping label I send you).

      In most cases I offer a 2 business day turnaround (if it arrives to me Monday then I ship Wednesday).

      Because kickstarter messages are here permanently I have set up an email address that I can disable if the spam becomes to great. Email at then I will reply to you from my real email address. Feel free to ask any questions you need to as far as my services offered.

      I communicate extremely quickly and you will find your experience with me as refreshing as possible.

      I am not affiliated with excel physics in any way minus the fact that I backed 3 basic kits and bought a source disk.

      My APOC is also not sent until today

      -Sorry, that got sent to soon ;)

      Just wondering, it has been some days now - i think i am d'accord with most people: Still not trying to rush, i do realize it must be quite some strain to try and fulfill the orders. But at the same time it would be great to be kept in the loop

      Hey guys - I don't think anyone expects Kickstarter projects to be exactly on time, but it would be nice to throw your backers a little bit of info from time to time when you fail to meet your estimated delivery dates. The last update was over a month and a half ago

      For those of you getting your Assembled APOCS in the mail soon, I posted a short list of radioactive sources you can buy to test our your APOC!

    17. ExcelPhysics 2-time creator on October 4, 2013

      @Natasha We're working on the last batch of 40 some Assembled APOCs, you will be getting an notice of shipment in 3-5 days.

      No reply to my Sept. 3rd post...
      I hear some chatter of software, but when will the hardware be delivered?

      Hi Matt and David - sounds very good, I'm looking forward to the experiments & trying out the software.

    20. ExcelPhysics 2-time creator on October 2, 2013

      @herbert, We are getting closer to finished with all the assembly of the detectors, so then we will have more time to devote to the software. We have spent a great deal of time on it already (between ourselves or friends) and are making good progress on the apps, however still buggy and not ready for prime time. I did do some videos on linking the APOC to a computer and analyzing the pulses with PRA software and using the Arduino to do counts per minute measurements. within the next few weeks assembly will be done and we will make more videos and tutorials on different experiments and measurement techniques, basically fun stuff.

    21. ExcelPhysics 2-time creator on October 2, 2013

      @arn We have been working hard to get all the Apoc units built, calibrated and shipped, and have not had much time to work on the Reddit, but we will try and post more frequently. I am very happy to see that you got your detector kit built and working though!

      Received my kit a while ago and assembled it over the last 3 days. Soldering was a bit tough since I've not had any practice in a long time and the board and solder-pads are very small. However after soldering and assembly it worked right off the bat. I ripped out an americium tablet from a smoke-alarm (as recommended on the website) and calibrated against that. Works beautifully. Now I'm thinking about several ways to mod it. I have some ideas I'll post later.

      Hi, i´m still waiting for my assembled APOC. I thought it would be delivered in July and now it is September. Can you give me any info what is the status of the shipment now?

    26. antimix on September 8, 2013

      @ExcelPhysics I mounted my kit, and now it seems to work.
      - A 0.1pF condenser was missed from the shipping box, I was lucky to have one.
      - Mounting was tricky, due to very small holes, requiring a good soldering skills, a very steady hand, and a small iron tip, Not for all.
      - You did not mention if the double face PCB was already UP/DOWN connected and it was not necessary solder up and down any component.
      - In the doubt I soldered doubled, and this caused to much heath to be absorbed by some components with little damage. Probably it was not necessary.
      - I will need to get some Thorium 232 this week, so that l could try a better calibration. My Potassium Chlorate contained in the salt did not react at all.
      - Still not tested with iPhone and Arduino.

      @ExcelPhysics not sure whether the Uk ones have shipped yet - but would like to upgrade my 'kit' to an assembled one if possible?

    28. George Mack on September 5, 2013

      Just poking it out there, seeing not all of them have been delivered yet my "right now" shipping might appeal to a small market. Also seeing that there is no additional ability to purchase assembled units the $80 and $100 price points are mute. I've been buying and selling on eBay for a long time and I often get better than market value from people because I am reliable and ship fast.

      Herbert on September 5, 2013

      @George Mack: You ask for US $149.99 on ebay for an assembled APOC basic - wow. One would really have to be desperate to buy it from you, since excelphysics asked 80$ for the same product here as early bird or 100$ regular... I guess if they offer it officially in their shop it will still be cheaper than your offer.

    30. George Mack on September 5, 2013

      my friend stiffed me with an APOC basic after I ordered from him, if you want one assembled and tested, i ship within 24 hours…

      Great device!

      I've been toying with it to get a feel for where the "radiation free" area is around a CT Scanner.

      Now I need a tool to measure dose/time (and to brush up on my very rusty oscilloscope skills, once I figure out how to get my Galaxy S3 to work with it using the audio cable).

      Any way we'll be able to upgrade a Basic to an Advanced (in the future)???

    36. Pascal on August 28, 2013

      Is it normal that until today I have not received my APOC yet?
      Could you give me some info on why?

    37. antimix on August 28, 2013

      Hi, I just received my APOC kit in Italy.
      I will assemble in the next week end.
      Then I will try with one iPhone APP. This is not your "unreleased" app, but another iPhone APP that claims to work with any radiation device that "emits" the click signal through the audio cable.
      I am curious to see the results and how it works.
      Best Regards

      One thing I noticed while playing around with the assembled APOC: Even after a conservative calibration it is very sensitive to some HF-signals. If I bring it near a 4 MHz oszillator on an Arduino shield it goes haywire. Is some part of the electronics working as antenna boosting the HF-Noise, or are the photodiodes somehow able to pick up HF? If so, how much of the picked up signals are HF-Noise and will this be distinguishable from true gamma events with the analysis application to come?

      Just spent a nice (rainy) sunday afternoon assembling the apoc kit following the videos. Everything worked like a charm, even though I have not soldered for a long time - it was fun, and something I wanted to to again for a long time. So thank you excel physics for a really great project and a neat radiation detector.

      Do you know when the first version of smartphone and/or PC-Software will be available? Ever since your demo video with the isotope detection I'm looking forward to try this myself.

      I am off to South Korea next weds morning should I attempt the build to take it with me?


    48. Tony Jones on August 7, 2013

      Alright, finally sat down with my kit. Outcome is not too good. On/off switch is unreliable and LED is green. Also, there is output regardless of CLK jumper setting. My best guess is I got these items too hot. What are the part numbers for a new switch and four prong header to fit the board?

      Jose Rodriguez on August 6, 2013

      I just finished calibrating mine and it worked (it ticks)! The PCB assembly was not hard (no SMD's). But now that it works, what to do with it? Also what are the headers for, are they documented somewhere? And a schematic diagram would be nice ...
