  1. If you want to express concerns about these rules so that it's heard by the people making the rules who do you contact?
  2. I shot and ROed at Sig Academy this weekend. It was a heck of a match with some great stages and 340 shooters to run. The day the ROs shot was miserable with heavy rain on and off the entire day. While running between tents my guns fell out of the holster (unloaded). It spent a good 30 seconds in a puddle in the rain before another RO brought it to me. Yes I tightened up the holster, it loosened over the years. I took it to the cleaning area in the Academy and one of their instructors asked me what happened and when I told him about dropping it in the mud he said we'll take care of that and got on the phone trying to find someone. Jay, one of the range masters, to detail strip and clean my gun for me. He took the frame and slide apart and cleaned the entire gun and replaced all the springs for free and I was able to get back to the match and finish. The trigger is much smoother now and I got home without any rust. It was going to be days until I could clean the gun since I had to RO the weekend so it could have been bad. I just wanted to share this positive experience.
  3. Very excited to try out a new Savage 16FHSS in .223 that I got. I bought this Leupold 1-piece base which as far as I can tell is correct for the gun. It only has three screw holes (receiver has four), and the rear ring actually sits over the edge of the ejection port, but I checked and it seems like it wouldn't interfere with cycling. It comes with three Torx screws, and one of them is longer than the others. Where I am supposed to use the longer screw? I tried to RTFM, but didn't find an answer.
  4. I purchased two pairs of the GDT sights, have yet to shoot either successfully yet. On the first pair the rear sight could actually rotate on the jigger that is used for elevation and change position enough to bug me. I fixed that by putting in some PTFE tape and now it jiggles but always returns to the same spot. Ugly as sin but functional. The second sight set I bought did not have that issue. The rear sight will rotate right on the pin, but returns to the same spot. It will not rotate left (the other rotates in both directions). One thing I am noticing is that the front sight is a tad crooked relative to the wings. Assuming I can successfully sight these in I would say not bad. For the price you could buy several to get a good one.
  5. I was going to go on top. I want to try out a dot and see how that works for me compared to the 1-4x. How far forward/back should I mount the dot? If I do it all the way at the back I will have a wider field of view through the scope but the dot will cover more of the target? I know that would be a problem shooting plates or clays.
  6. Thanks for your help. I was able to persuade it to go on. Now to figure out what rings to use for my Ultradot 30.
  7. Thanks Dan that is what I am going to go with.
  8. Hi Dan, These aren't changes for the match, I am going to go as is. The GDT offset irons are DD clones. See GDT on Amazon. Stag 0H uppers are the same as 1H just not shipped with a rear sight so it is 16" barrel flat top. Thanks [edit] I found that the Troy Alpha rail has an ID of 1.36 so that seems like a stretch. The 1.56 of the Samson evolution is tight, but I think I can minimize the gas block that far. Anyone with more experience?
  9. It's definitely pinned. I live in Mass and had to get it that way. The YHM two piece doesn't look like a very solid platform for a front sight. The Troy and Samson rails look attractive. I can't find the ID of the Troy rail and the manual link is broken. Also not sure which Troy I would want, the Alpha rail? TRX requires a new barrel nut?
  10. Thanks. Hack saw actually. When I talked to JP they said that their 15.5 inch would leave just the comp exposed. They have photos of guns configured that way. I looked at the Ranier and Samson and the ID is 1.5 inches instead of the 1.75 ID that JP has. Can't tell the ID of the troy hand guards and they also have a confusing number of options. I am not sure I can make my gas block that low profile?
  11. I have a post ban Stag 0H upper with a pinned muzzle brake, GDT offset irons, and a Nikon 1-4 scope. Everything is mounted on the receiver since the handguards have no rails. Sight radius for the irons is poor, they are interfering with scope placement, and the scope is interfering with accessing the charging handle. Being a n00b I now have an ummm... low profile gas block, but I just realized I still can't get the new barrel nut that most new handguards require over the muzzle device and gas block. Is there a hand guard, free float or otherwise that I can mount a sight on in this situation? A longer 15 inch hand guard would be a plus as well as a light. I am also open to some other offset sighting mechanism that works with a pinned muzzle brake.
  12. Michael, if you want me to add you to the project so you can commit your changes PM me your Google account name.
  13. I would love to see this happen. Lowering the barrier to entry is a good thing. It's easy to say that you don't want to let this new equipment in, but it isn't like S&W is selling new 5" 625s anymore. Remember how this sport works for the people who don't already have their equipment.
  14. An easy way to hack it up would be to replace the system volume jigger (which may not even be right anymore) with new text and implementation that adjusts this value.
  15. getMaxAmplitude() is doing the same thing. The MediaRecorder is reading in the samples and keeping track of the max sample. The disadvantage of that approach is that it doesn't differentiate between a short loud sound and a long loud sound. You also can't accurately place things in time because you can't control when getMaxAmplitude() will be invoked (although realistically it will be regular). By reading the samples directly you can count samples to determine exactly when something happened. EDIT Ok maybe I'm wrong. I tried to look up the implementation of GET_MAX_AMPLITUDE and it looks like it is implementation specific. There is none defined as part of Android. http://www.google.co.in/codesearch/p?hl=en#MDtG1cTEFDc/android/author/authordriver.cpp&q=getMaxAmplitude%20package:git://android.git.kernel.org&d=2 There is no real description about what the value return is either http://developer.android.com/reference/android/media/MediaRecorder.html#getMaxAmplitude()
  16. The maximum is is 32768. So 10-15k would be reasonable to try and detect the stuff that showed up in the recording. Interesting. This is why the value is set to 32k. Android doesn't provide any way to adjust the levels. You get the digital data and that is it. It would be nice to be able to adjust it before the digital to analog conversion so the app could get a relative sense of how loud things are, but I don't think that is possible. I submitted an issue for this http://code.google.com/p/android/issues/detail?id=6554&can=4&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars but it is hasn't been looked at yet and no one has voted for it.
  17. Do we need to lower that value or ?? Michael. My thinking is that if you need to then there is something else wrong. That is why I didn't bother making it adjustable. The pictures show what a loud noise should looks like. The amplitude is off the charts so it looks square because the microphone can't tell how loud it is. I think using one of the original versions that works for someone else and busting an actual cap might tell us something. Michael does it work for you? CiDirkona, you could also use Hertz to record a clip containing an actual gunshot and we could see what that looks like on your phone.
  18. That audio is definitely little endian so that setting needs to go back to what it was. That is why it detects shots during silence. Here is a screenshot comparing audio I recorded of gun shots and the audio you sent me You can see that the shots are much louder and go square for a while. This is what the shot detector looks for. It counts the number of audio samples that are square in a row. In the audio you sent me there isn't enough of a volume difference between your voice and flicking the mic which is a concern. This is what it looks like when I flick and blow my mic: You can see that it also maxes out for a little while. When you flick the mic you need to hit the mic directly with your nail to get the right sound. It should smart a little ;-) The sensitivity adjustment you see doesn't control how sensitive it is to volume. http://code.google.com/p/openshottimer/source/browse/trunk/src/org/ost/AmplitudeSpikeShotDetector.java#31 That value determines how loud something has to be in order to be considered part of a shot. If you set it too low then it will start to detect other things as shots. However shots (and flicks, and blowing on the mic) should be loud enough that the value that is there works with just about any mic. Gun shots are really really loud! Well beyond the capacity of a normal microphone to discern exactly how loud they are (hence the square sound waves). That is what is puzzling about your situation.
  19. Endianness has to do with byte order and not the size of the samples. The behavior your describing sounds like big endian is wrong. Can you use the Hertz audio recording app to record an 8khz 16-bit file where you flick the mic and speak into it. If we could look at that we could get an idea of what kind of audio is coming out of the mic. I could run it through the unit tests and see if the shot detector does the right thing with it.
  20. I wonder if his phone is producing big-endian audio. http://code.google.com/p/openshottimer/source/browse/trunk/src/org/ost/AmplitudeSpikeShotDetector.java#56 If you update that to BIG_ENDIAN it might work.
  21. Everything I used is in the repository. I tested the UI using the spurious shot detector to generate data. There is a unit test (ShotDetectorTest) that runs some audio samples through a the AmplitudeSpikeShotDetector and checks to that the correct number of shots is detected. The samples have limited utility because there is a lot of variation between handset mics. I never tried to have it record the audio. It's a good idea, you just want to be sure to only keep the recording of the last string in order to bound the space usage. You can modify AudioPuller (a nested class in ShotString) to do that.
  22. I would really like to work on this, but it has been forever and Google still hasn't addressed the issue. http://code.google.com/p/android/issues/detail?id=3434&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars This is a top 75 issue out of 7665 issues. If it were like the iPhone and there were a small range of devices to get it working for then I would hack away until something works. With Android there are a ton of devices running all kinds of apps that can cause problems.
  23. Very cool. Might try it one day, but I need to get my reloads down before this will be the right place to pick up time. I don't want to start a tangential discussion, but it is nice to come across a patent that is worthwhile.
  24. I leave it in. I don't think it's necessary but it is one less thing to rattle and the pedantic software engineer in me can't help but think it was put in there for a purpose even if I don't know what that purpose is. I have one gun that I took it out from and I haven't taken the side plate off since so it hasn't gone back in. That gun runs fine as well and I used it at matches for a few months.
