  1. @mnewxcv have you seen this https://mewlips.github.io/nx-remote-controller-mod/ ? It's also included in NX-KS since version 2.56 and it works on NX500 (but at screen resolution, so quality not high).
  2. Yes, I have compiled several modules and toyed with them and they work, even NFS mount works (but slowly, very slowly). I didn't want to modify root more than I had to so I put modules in /opt. Following is a proof of concept via file containing the ext2 file system. For example, to mount NFS from server A.B.C.D to store images directly to it (playback is very slow): busybox mount -o nolock,rw,hard,intr,vers=3 -t nfs A.B.C.D:/mnt/export /opt/storage/sdcard/DCIM/ So, it can be done, but it will be unmounted every time the camera goes to sleep, etc. It can be remounted using auto scripts from keyscan or more feature complete custom mod pack. I wanted to make encrypted container and mount it to DCIM but I haven't had free time lately (it's entirely doable, openssl shows up to 50MB/s depending on the algorithm). type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes rc4 41978.37k 46139.88k 47931.48k 48086.52k 48323.96k aes-128 cbc 20183.59k 21377.81k 21916.21k 21961.44k 21975.41k aes-192 cbc 17364.14k 18274.48k 18664.45k 18798.15k 18802.16k aes-256 cbc 15348.79k 16012.25k 16353.15k 16344.79k 16396.00k type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes des cbc 12303.37k 12949.75k 13082.44k 13153.05k 13177.24k des ede3 4694.62k 4808.55k 4812.70k 4835.26k 4821.14k blowfish cbc 21719.40k 24047.88k 24643.79k 24752.36k 24857.40k All that said, it turns out that performance wise (ex)FAT is very efficient and you wouldn't get better performance using other file systems (I did not test F2FS though).
  3. Sorry, just read this, no experience with this.
  4. You can use ecryptfs which produces "normal" files just with scrambled names and contents (used for example by Ubuntu if you select encryption of the home directory during the install) as well as block level encryption (see LUKS and Librecrypt for Windows use) that can work either on a complete card, a partition or use a file on the card as a block device. Both are vastly better than encryption after the image was saved. Also an option is to use network share to store photos so nothing is on the camera either way (but it's quite slow, around 3MB/s so ~4s per full resolution jpeg). The problem I have with nx500 is that it hangs if it cannot open the file it thinks exists (even the simple deletion from terminal can confuse playback).
  5. No, ML HDR mode works by two successive exposures at two different ISOs. We don't have that option here.
  6. FWIW http://www.pentaxforums.com/articles/photo-articles/evolution-of-pentax-k-mount.html Seems it uses a single digital pin for communication with lens
  7. Focus control is already doable, but what exactly did you have in mind?
  8. Camera does not know actual distance, I've wanted to calibrate my lenses (it's straight forward procedure to record reported focus values at exact distances from the sensor at, let's say, 5 points and interpolate the others as it's not linear) but never had the time. We would also need to find a faster way to get focus distance value as the current method takes ~0.3s which is too slow.
  9. I'm just trying to help a friend with ninja2 who's having problems (ie, nothing on it) and he's not near so I could help him in person. His problem is that nx500 seems locked to 60Hz output over HDMI and apparently ninja 2 supports only up to 30Hz in 1080p (it does 60 at 1080i).
  10. It's probably slightly off topic but had anyone succeeded with nx500 and ninja2 or similar 1080p30 external recorder? A friend has it but it's not showing anything due to 60fps output.
  11. @lucabutera great news, but may I suggest that you don't call the dumb adapter "dumb" but "manual"? This does not sound nice at the end " Receive the NX-L dumb! "
  12. I measured roughly some time ago and got ~8ms rolling shutter for 2.5k on NX500. All other modes (FHD, UHD, 4K) were 24-30ms. Could someone else verify that and could someone more experienced than me guesstimate whether it's skipping lines, binning, etc? Occasional weird horizontal line pattern suggest it might skip lines but I'm not sure how to check properly.
  13. @sandro I created a small tool that shows a button with black background and white text at given position and size that enables one to have on screen "button" for REC or SHUTTER or whatever. You could use it as it is as a "black screen" (just set the text to " " and position to 0 0 and size to 720 480) and to start the time lapse. I do it often to preserve the battery (AMOLED uses almost nothing for black screen). To remove it from screen just press and hold it for 5+ seconds. I also made a separate tool for time lapse that can have black screen as well as black screen with small red frame counter (useful). It can also make short videos instead of photos (let's say 10s video every 2 minutes, etc).
  14. @kidzrevil Can't speak for others but I have nx500 so no evf from me Great work Luca, I tried something similar (but much more primitive) with m42 a long time ago but I was unable to position the added elements precisely enough and got mostly useless results - your results are very positive! Regarding canon vs nikon - yes it is true that due to longer flange straight adapter will not work, but let's wait and see how much of the space is actually used by this adapter - it might be doable to shave a millimeter or there and get canon lenses to work.
  15. I don't have NX1 so I cannot help you there
  16. I don't know, I don't use that mod pack, someone else will have to reply to that
  17. Download this file https://github.com/ottokiksmaler/nx500_nx1_modding/blob/master/video-bitrate-mods/nx-patch/nx-patch.zip?raw=true And extract it to SD card root so that the file info.tg is in the root directory of your SD card. I don't have a Mac but I guess this should be trivial from any file manager. *absolutely read the Readme file* Then put SD card in camera, remove battery, reinsert the battery and power the camera on. Follow the instructions.
  18. @vasile is correct - if you are not sure what you are doing - don't do it. Added a large warning to github.
  19. No reason why it wouldn't, but I have no way to test it on NX1.
  20. FWIW, we seem to now have a method to make bitrate mods permanent (in hibernation image) so independent of Bluetooth and similar. But this currently applies only to bitrate mods (but should apply to 2.5k on NX500 as well). Other mods still depend on Bluetooth. We are all working on further improvements. See here for more information https://github.com/ottokiksmaler/nx500_nx1_modding/blob/master/Permanent_bitrate_mods.md
  21. @kidzrevil they didn't close the hole we are using, mods work fine, but due to changes in firmware the bitrate hacks don't work (as they work with messing with memory locations of already running process, etc). Enabling 2.5k on nx500 works when adapted to new memory locations (already done by Kino Seed). You just have to wait and see what happens, but if you need higher bitrates don't update yet.
  22. Dumb question, but you do it like this : press EV, click OK while EV still pressed, release EV?
  23. It's here (this link contains all the versions and commit data) https://github.com/ottokiksmaler/nx500_nx1_modding/commits/master/NX-KS.zip
  24. You are probably running in factory mode. Do you have file info.tg on the sd card? How do you use the hack? Vasile or Kino Seed zip?
  25. @sandro sure, that's what I'm doing. Nx1/nx500 are running tizen 2.2 Linux with full stack X and built in EFL toolkit (terrible toolkit, but that's what it's got). It would be possible to cross compile Qt and use that as well as other usual suspects like wx and the like. For storage on camera, you have read write partition under /opt and of course /mnt/mmc. If you take a look at my github you will see several examples (like small utilities fit focus stacking, popup prompt windows, etc).
