DIY Remote shutter release for Samsung NX-series cameras

I’m using Samsung NX1000 for aerial photography. The camera has a nifty feature of using smartphone as a remote viewfinder and shutter release but unfortunately the good idea is watered by buggy and limited program and the feature freezes the whole camera all too often. Fortunately there is a simple way of triggering the shutter via cameras usb-port. The trick is to have 68K resistor between ID and GND pins. After this USB data lines can be used to trigger camera focus and shutter.



Tip: If you have spare micro-usb cables, it’s easy to source a connector from the cable that came with the camera. Just squeeze black plastic around the connector with a pliers and the plastic casing will crack open exposing the connector. The connector on the cable has a small pcb, which makes it easy to solder the required resistor in place. If you use smd resistor, the casing can even be reassembled.

The cable described above works fine for manual use, but to use the camera for aerial photography some interface for rc receiver is needed. Fortunately this is easily achieved with a small arduino program, which reads pwm value from receiver servo port and then pulls either shutter or focus line low based on channel value. The compiled code size is under two kilobytes, so it’s possible to use small and inexpensive microcontroller like AtTiny2313.


RC interface for camera

The schematics and sources can be found at: https://github.com/JanneMantyharju/nxshutter

Compatible with (at least) following models: NX20, NX210, NX1000, NX1100 and NX2000

Update: If you don’t want to make your own, I’m selling these ready made. Just drop me a message.

    Would like to try this myself. Any chance you could share a picture of your modified USB cable?

  2. 16/05/2013 at 23:37

    Unfortunately I already reassembled the connector and sealed it with heat shrink tubing. But as said, if you crack open the original connector, there is a small pcb inside, with just enough space for smd resistor between id and gnd pins.

    can this be used for a laser line to then trigger the shutter , if so can you make one up please.

    • 14/06/2013 at 17:39

      Do you mean that you would have something like a laser pointer targeted to a sensor and if the beam breaks, the camera would be triggered?

    Hi, I’m using NX1000 for aerial photography also, have you consider supplying GPS info through HotShoe connector so the images would georeferece automatically? I am using U-blox GPS with APM 2.5.
    Thanks, Marek

    • 17/06/2013 at 09:59

      I also thought about this. The problem is that nobody seems to have figured out how the hotshoe gps transmits the data to the camera. I don’t own the accessory gps myself, so I can’t reverse-engineer it.

    Hi Antibore,
    Can NX1000 ‘s Micro USB output support video downlink ? Can the samsung remote viewfinder be able to transfer the live video down to your smartphone at a ht of 300m?

    • 29/06/2013 at 12:34

      No to both of the questions.

  8. Kong
    26/06/2013 at 19:32

    If you’re using Remote Viewfinder to transfer the video signal to your smartphone then, is the video signal be able reach your smartphone if your FPV platform reaches about 200~300m above?

    • 29/06/2013 at 11:49

      I’m not using remote viewfinder, since it freezes too often to be usable. The wlan range is also too limited.

    how do i load the code and where do get it from

  10. 19/08/2013 at 01:26

    I am looking at your program loop and trying to figure out how the camera responds to focus and shutter lines pulled to ground. When I try this the camera does not respond to just the shutter line grounded. Nor does it respond when both focus and shutter are grounded.

    Do you know if you have to pull focus low before shutter? For how long? Do you need to keep focus line low during the shutter low? How did you figure that out?

    • 19/08/2013 at 08:49

      One thing I noticed is that the camera is quite picky about the id resistor value. I did not have the original cable, so I could not reverse engineer the correct value. Try playing around with a different values, 80k might be a good pick. With most values, the shutter works, but focus might not. When testing, you can eliminate the avr as an error source and just manually touch ground wire with a focus wire. Make sure you have latest firmware and SD-card installed when testing the cable.

  11. 19/08/2013 at 16:33

    Thanks for the reply. I figured this out. First off my camera is the NX300 (which does respond the the same usb remote as all the others). But I have the lens removed from the camera because of the application (a 35mm film telecine) and a 50mm Lomo OCT-19 physically de-coupled from the camera body on a sliding rod rack. So although the lens present plunger pin has been closed with a small piece of inserted plastic inside the rim of the lens mount thus allowing the camera to fire, the gold contacts that would normally talk to the lens electronics are disconnected. This makes the camera operate wrong in full Manual mode. You set the ISO and the the shutter speed but the shutter speed still auto adjusts.

    To get around this I have the camera in Shutter Priority mode and it works fine. I think that it is actually attempting to set the aperture of the lens and failing during focus button push but it continues to allow manual ISO and shutter speed. In this mode the USB remote signals require that you first close the focus to ground and then very shortly thereafter close the shutter. I ended up with only needing a 100 microsecond delay between them and then only a 5000 microsecond shutter line closure to properly actuate the the image capture. Then both lines are opened again.

    I have the lines driven by a Velleman K8055 I/O USB board and a Perl program running on the connected laptop. Seems to work great. Your DIY instructions were a big time saver for me.

    I believe that the 68k resistor is the correct value. There are 3 possible values listed for OTP cables. This link http://en.wikipedia.org/wiki/USB_On-The-Go states:

    “Three additional ID pin states are defined[4] at the nominal resistance values of 124 kΩ, 68 kΩ, and 36.5 kΩ, with respect to the ground pin. These permit the device to work with a USB Accessory Charger Adapter which allows the OTG device to be attached to both a charger and another device simultaneously.[6] These three states are used in the cases of:

    A charger and either no device or an A-device that is not asserting VBUS (not providing power) are attached. The OTG device is allowed to charge and initiate SRP but not connect.[6]
    A charger and an A-device that is asserting VBUS (is providing power) are attached. The OTG device is allowed to charge and connect but not initiate SRP.[6]
    A charger and a B-device are attached. The OTG device is allowed to charge and enter host mode.[6]”

      Does this mean, that ist should be possible to build an adapter which provides two functions: charging the camera while shooting pictures via remote trigger/fire?


      • 11/07/2016 at 08:51

        I haven’t tried, but likely yes, since the trigger does not require Vin to be connected.

    Hello, i see you are delving deep into the samsung nx series. You know, i have an NX210 and i recently bought 2 yongnuos YN 560 III but they refuse to fire from the hot shoe, the work great in slave mode. i like them so much that i’m willing to go into the electronics to try to make them work from my nx hot shoe. do you happen to know the NX’s hotshoe pinout?

    • 24/12/2013 at 23:17

      Sorry, I don’t know it. I searched for it for a quite bit myself, I was interested how the image is transfered to electronic viewfinder. Currently I’m trying to sell my NX1000. I grew tired to autofocus, which fails most of the time in the dark.

    Hello. I have got a NX300 to do aerial mapping with the pixhawk autopilot.
    There is a port on the autopilot that is aimed to shoot the camera within a predeterminaded time or ground space in meters…
    My question is: can I simply plug the cable into the camera and into the autopilot to shot my photos? Or I will have to do some custom on the cable, inserting the 64k resitor?… Or I will not be able to shot directly from the autopilot signal….

    • 29/01/2014 at 20:59

      At least you have to have the resistor between usb id-pin and ground, otherwise the camera assumes that the cable is a standard usb-cable and not the shutter. Also make sure that pixhawk only pulls usb-pins low and does not supply current to them.

  16. 12/02/2014 at 23:47

    Dear friend … i m also interested in connecting my nx 1000 to pixhawk for aerial photography. I tried to make such a cable but it was impossible for me to solder one . I m not good at it. What if i bought this … http://www.samsung.com/uk/consumer/smart-camera-camcorder/smart-nx/smart-nx-accessories/ED-SR2NX02 … and used the cable only to connect it to pixhawk by removing the upper part of the buttons and connecting it to futaba cable. Is there any way you could sell me such a cable ( i guess arduino is not required) in order to connect it to my pixhawk ? (i think it’s the same with apm). I live in Greece. If so what would be the price ?

    • 13/02/2014 at 13:47

      I did this previously for Mikrokopter board. You need an optocoupler between the camera and Pixhawk, like this (http://mikrokopter.de/ucwiki/en/ShutterCable). I can make you one, but I don’t have PCB designed it so it would be build to strip board. The price would be 29€ + 3€ for postage. Unfortunately I can’t provide you connector to pixhawk since I don’t have those in stock and the minimum order quantity seems to be quite large, so you’d also need something like this: http://www.uavrobotics.com.au/camera-cable-connector-p-77.html?osCsid=e1860bc58b95ca08ae8ace019aedfb5f

      • 13/02/2014 at 15:15

        But the only way to trigger the nx1000 is via usb i think. I can solder the futaba cable required on the one side of the optocoupler but according to your post i also need the construction u made with the 68k resistor. In this price will you provide me with the full package (apart from futaba cable) that will be functioning as long as i plug it on the camera and on pixhawk ?

      • 14/02/2014 at 15:37

        I can provide the usb-cable and optocoupler. You would need to provide the cable from pixhawk to servo connector.

    Hello Janne,
    Thank you for the well designed pcb you sent to me. (NL)

    I have got a question:
    The pcb you sent me got a id resistor code 823 = 82k
    The resistor in your schematic on top of this page is 68k

    Could this be the reason why my Samsung NX300 does not work with your pcb ?

    Any suggestions concerning range of the id resistor ?

    Any people here with a Samsung NX300 and a working remote shutter/focus pcb ?



    • 03/03/2014 at 16:49

      68k is the one used in the official remote. I have used 82k instead since I haven’t the 68k in my set and my NX1000 seems to not mind. It might be that NX300 is more picky about that. Can you try to change the resistor? Also just to be sure, try to short the focus and/or shutter lines to ground by hand to see if anything happens.
      Also have SD-card in the camera when trying it out. NX1000 let’s you take the pictures without SD but for some reason the remote shudder does not work without it.

    Samsung NX300:
    Hi Janne,
    Allready tested by hand with 68k resistor on my NX300: This works.
    Tried with several values of resistor above/under 68k (E12 resistor range) on the pcb but the Samsung NX300 does not give any reaction. (leds on pcb are on/of during switching)
    I think the NX300 is to picky concerning triggering in a different way..
    Any last suggestions ?

    • 11/03/2014 at 11:43

      If you tested that 68k resistor works, can you solder it to the pcb in place of the current resistor? There should be enough place even if you don’t have the smd version. I’ll make sure to use 68k in future pcb’s

      • Bart
        12/03/2014 at 01:13

        Allready did solder the 68k on the pcb… Doesn’t work.. (but leds acting ok)
        Voltage drop/resistance in AtTiny2313 to high ? (I’m just guessing)

      • 12/03/2014 at 01:24

        What the hell then.. The attiny should pull the lines to ground when active and other times they are left floating so voltage drop should not also be an issue. I was thinking how to verify this..

    Nice post. I’m alsi using nx1000 with hexacopter, here in Finland. How much do you charge of your shutters? And have you figured out how to use only nx1000 for fpv flight?

    • 12/03/2014 at 19:03

      To Finland I can send one for 25€, including postal. Fpv is a problem since you can’t get live feed from hdmi and wlan has limited range and bugs. That leaves only the accessory connector outputting viewfinder image, but the protocol is unknown. Drop me a mail if you need one!

    Hello. Could the NXshooter 2.1 (I have got it from you by ebay) used on the situation showed on http://plane.ardupilot.com/wiki/common-pixhawk-auto-camera-trigger-without-chdk/ ?
    Could you post some videos to show how we use the product….

    • 26/03/2014 at 19:54

      @fabio: Sorry, I can’t post videos as I don’t have Pixhawk, but since pixhawk seems to be able to output pwm (servo signal) as camera output, it should work straight away with the shutter board. Just instead of the receiver, connect the board to pixhawk aux output. Follow the configuration guide on the page for which you posted the link.

  21. Anonymous
    28/03/2014 at 03:46

    According to the specs of my previous note, the PWM value for the state ‘push’ is on the value 1800… I tryed it with the cable connected to the pcb and nothing happens… Is thare a specifc value to enter, so the pcb will know that I want to push de botton to trigger the camera?

    • 28/03/2014 at 15:59

      I don’t remember the exact pwm values, but connect it to your receiver, check that both leds light up for one second after power is switched on. Then increase channel value, green led should switch on when focus is activated and red for the shutter.
      One user reported that some cameras are more picky for id resistor value. If the leds work properly, but the camera does not react, change the id resistor (near the connectors) to 68k ohms.

  22. Fabio Lobo
    28/03/2014 at 04:26

    How could I test the pcb? Can I use a some kind of ‘metal stick’ to force it to focus and shoot my camera? I am realy having troubles to make it work… Can you draw a schema to test the pcb?

    • 28/03/2014 at 16:01

      The schematic is in the post. I should update it to the version with leds. You can manually activate the shutter and focus by shorting black wire and white wire (focus) or black & red (shutter)

  23. 06/04/2014 at 06:29

    Hello Antibore, I consider a very very good camera Samsung Nx1000, shooting in F;8 aperture it takes very sharp images, But now my questios is; if could II take live video from it for fpv, while also taking remote photographs with it?. If yes I want to buy you a shutter pcb. Thanks Julián from Argentina

    • 06/04/2014 at 15:59

      Check from the camera specs (I don’t own nx1000 anymore, but I don’t think it can shoot video and stills at the same time)

      • Joe Paisley
        26/06/2014 at 13:46

        That’s correct. If you start the video, then hit the remote shutter. The camera will take a still and stop the video. So you can take video for the first part of the flight, with not start/stop control, then switch to stills, with control, for the later part.

    any help will be greatly apreciated. thanks

    • 05/06/2014 at 09:03

      Hi! This happens because you are trying to compile the code for atmega328 or similar processor, which has UCSR0B register instead. If you are actually using AtTiny2313 processor, you need to install support for it to arduino (https://code.google.com/p/arduino-tiny/). If you want to use some other processor, you can safely comment out that line, it’s just turns off the serial port. In that case modify the pin definitions as needed.

    Thank you , your top diagram is exactly what I have been looking for, nice and clear.
    I have read that the nx usb can be used for charging, do you know anything about this? I’m hoping it would power the cam from this rather than trying to charge the internal battery.
    I’m researching into making a side grip to contain 2 or 3 batteries and a focus/shoot button

    • 26/06/2014 at 09:19

      Thank you!
      I’m fairly sure that the camera can’t be charged from USB-port, but if that’s possible, positive wire in usb connector is not used by the shutter, so feel free to supply current using that.

    Hi Antibore, I own a NX1000 and I have some questions…

    Was about to order a 68KOhm resistor, they came with different power for example from 0.25W to 10W, which one have I to choose? If am rigth it depends on how many current pass through the usb cable because: V=RI and W=VI
    I dont want to damage my camera

    Anyway if you want to build a TriggerTrap cable you have to follow:

    1) building the dongle : http://www.diyphotography.net/building-diy-trigger-trap/
    2) building the camera cable : this guide

    • 21/08/2014 at 16:19

      The current flowing through the resistor is minimal, so you can pick resistor with any watt value. In practice you should pick the one with the lowest value to get smallest sized resistor.
      ps. I sent you mail about ready made cable.

    Thanks in advance.
    Best Regards
    Jose A.

    • 20/10/2014 at 21:50

      I sent the hex file you by email. The probable reason why you are getting compilation errors is that the code is written fot AtTiny2313 processor and Arduino compiles for AtMega328 by default. To target tiny devices, you need to install the AtTiny core (https://code.google.com/p/arduino-tiny/)

    Hi, I tried the circuit proposed here but with no results as , it seems that the NX2000 not detect the circuit connected to the micro usb .
    I believe it is due to contact with the ID resistor 68K .
    Have you encountered this problem ? There are alternatives functioning ?
    Thank you and congratulations for the forum rich and well done

      I sent you mail yesterday, but apparently it vanished somewhere. Here’s a copy of the message:

      About the NX-triggers, I currently have just one in stock. I already ordered new parts, but it will go to the middle of next month before I get all the parts. I can send them separately though. The price would be 24€/pcs and 1.5€ for shipping. Send the payment via paypal to janne.mantyharju@iki.fi and let me know your delivery address.

    Hello 😉 I also using NX1000 with my copter with pixhawk 🙂 shutter cable I made by myself using this instructions 🙂 it’s hard to solder that tiny tiny resistor but possible (for me it took 2 hours) ;D and everything working great 🙂

    • Anonymous
      02/02/2015 at 21:15

      Yes but this does not work on the NX2000 – it needs a “pre-shutter” press for the focus.

  41. 04/02/2015 at 13:35

    Hello, I tried to make a cable to use it with my nx300. Shorting the pins 2-5 the focus works but shorting 3-5 the shutter doesn’t work. It seems doing something, that means that when the screen goes black after a few seconds, shorting the shutter wakes the screen. Also in the play menu it shows up the on screen menu with shorting the shutter. But the shutter of the camera doesn’t close.
    Have you got any idea what is the problem with this?

    • 04/02/2015 at 13:38

      No idea. I haven’t encountered that and I don’t have NX300 to test with.

    • Mark
      04/02/2015 at 14:07

      The cable is only for the nx1000. For the nx2000 and the 300 series you need the circuit or a solution like this: http://diydrones.com/profiles/blog/show?id=705844%3ABlogPost%3A1646005&commentId=705844%3AComment%3A1646381&xg_source=activity

      • 04/02/2015 at 14:14

        Good to know. With this circuit you can do both focusing and triggering. It’s also possible to modify it to do both automatically from one pulse.

      • 06/02/2015 at 22:51

        Thank you Mark. I made the circuit with the timer of the link and i managed to remote trigger the shutter with a transistor as a switch (or simple with a button).

        That i didn’t manage to do is to trigger the transistor with the pulse of the iphone. Maybe it needs be amplified for that. If you know how to do that i would appreciate that.

      Hi, did you test it with the NX500? Does it work?

      • 17/05/2015 at 15:11

        I can’t guarantee since I don’t have NX500 to test with. The shutter release generally works with all the cameras in NX-series with few exceptions.

    Hello. I have a DJI Phantom 2 quadcopter and a NX1100. Do you have a solution that will enable that quadopter’s controller to trigger the shutter on that camera via the micro usb port?

    • 14/03/2015 at 15:31

      I don’t have dji to test with, but it appears that it’s much more closed product that general purpose rc transmitters/receivers. One option is that I supply you a board that triggers camera continuously on selected intervals.

      • Don
        14/03/2015 at 17:39

        Thank you for you’re prompt reply. That solution sounds good. Can you direct me to a link that has a photo of the board and other details? How much cost, and how much time before you can ship? I am in the USA, but of course, I would pay shipping. Also, I would like to pay with Pay Pal.

    Hello antibore.

    In my case I need a Samsung NX Mini shooting in each of the waypoints that you previously configured on the flight mission loaded in PixHawk4. I have seen examples of how to do something similar for the NX1000, NX2000 and NX3000 models, but not if the same can be done for the NX Mini or that way to do it … I do not know quite how to do it, have you had any experience with NX Mini model?

    Thank you very much and congratulations for the comprehensive blog.

    Raul Otero.

    • 14/04/2015 at 23:33

      This should work for also for NX Mini, since similar shutters for fixed use are working for NX mini. Also if I remember correctly, one of my customers was using NX Mini.

  45. Raúl Otero Fernández
    14/04/2015 at 23:42


    Thank you very much for the quick response.

    I still have no camera, I try to make the connection and verify that everything works as soon as possible. I found this link that another form of connection is shown for NX1000, http://diydrones.com/profiles/blogs/diy-samsung-trigger-for-apm , do you think would be valid too?

    I would be very grateful if you could confirm with your client that the connection type you explain in your blog is suitable for NX Mini.

    Thanks again.

    This circuit works perfectly with my nx1000 but it doesn’t do anything with the NX3000 (body firmware:1.10). Are there anyone here who knows what’s different in nx3000 trigger mechanism?

    • Jeffrey
      21/05/2015 at 13:37


      I was wondering if this would work with an NX3000. Too bad to hear it doesn’t.
      Since there’s no timelapse function on the NX3000 I’d like to make a remote timer by using an Arduino.

      If anybody reverse engineers the shutter circuit of the NX3000, please let me know.

    • jwestenberg
      21/05/2015 at 18:06

      I contacted Samsung today and they told me that there is no remote shutter function on the NX3000. They couldn’t tell me if there will be a firmware update to change this, becausd they don’t know if the hardware is compatible with this function.

      • 21/05/2015 at 18:24

        I’m surprised that the average helpdesk person knew what the remote shutter release is =)

    Can you please move source code somewhere else? Gitorious is down for a while…

    Do you setting that shutter/focus pins directly to low-ground with that AVR? Or I need to use some transistor or something? Is that safe for camera? Cannot I damage camera when program will, for example, set pin to high?


    • 10/09/2015 at 19:46

      Hi! Sorry, migration to github has been on my list for a while. I’ll try this weekend.
      The avr just pulls pins to ground, otherwise it’s in high impedance state. It’s not safe to set pin to high, but at least my camera didn’t break down when I accidentally did that.

    Hi, I have an NX (model EK-gn120a) which runs Android and has a USB port that is also used for charging. I would like to be able to craft a cable that can be used to charge as well as be used for data over USB. I have seen some literature about specialized cables for this purpose. Are you aware of any details that may help me figure this out? I need to have it charge the battery via USB as well as interface with a NFC reader that is USB. I have tried with a passive hub and it does not work this way. Any help is greatly appreciated.

    I am really interested in your product.I just received my NX500 for X-mas and am needing a shutter release. I wanted to as though is this just for photo or video? It isn’t really a big deal if it is just limited to photos. Also, Can I ask what are all you aerial photographers doing in terms of live video feed? I hear getting live video feed through the micro hdmi is a pain and the usb doesn’t suppport it. Any help? Thank you!

    And Antibore, my email is listed below;


    • 29/12/2015 at 12:06

      I only had NX1000, so I can’t say anything certain for NX500. The shutter can trigger photos and video, provided that you can switch your camera into mode, where the shutter button triggers photo or video. In NX1000 this was possible as you could choose video from the mode dial.
      For live video, I bought hdmi -> composite adapter from eBay and connected that to the video transmitter only to learn that NX1000 can only show still pictures from the HDMI port. This might have been changed in NX500, but better to check first before buying equipment.
      I’ll mail you about the payment details if you want to buy the shutter release.

    10/02/2016 at 14:08

    Have you had the chance to test what is the minimal time between stopping an starting new video recording with remote trigger. I’m wondering if it would be possible to program uC to force continuous (spanned files) recording? The time would have to be less than 1/fps of a second.

    • 10/02/2016 at 14:14

      I haven’t, but for video it’s not surely possible as the camera spends considerable time when stopping the video recording. What would be the use case though? Wouldn’t taking the still pictures as series do the trick? For example NX500 can do 1.98 fps in continuous still mode using jpeg.

      • Tom
        10/02/2016 at 15:15

        Continuous video recording for sports as a second/remote camera (a workaround for the 29:59 EU limit). I was thinking of using NX500/NX1 for this.
        Japan (NTSC) version of GH4/G7 don’t have that limitation but the crop in 4K/1080p is a deal breaker, hey can spann files with no gap in the recording. I don’t think closing a file on SD card should be a bottle neck at least not at the fault of the hardware.

    Can anyone give me a hint where one can find a micro usb plug, cable or pigtail with all the 5 wires. I’ve been buying a number of cables and cutting up plugs but they all have only 4 terminals (1, 2, 3 and 5). The ID pin (4) doesn’t have any soldering tag!?

    • 22/09/2016 at 19:37

      I had the same problem. I tried to be lazy and buy ready cables from ebay, but in maybe 1 out of 10 had the ID-pin connected. Eventually I started just buying micro-usb connectors from ebay and soldering the cables myself. They cost next to nothing (maybe $1 for 10pcs), but soldering them is annoying and they can never be as durable as factory made cables where the connector is casted inside of rubber.

  81. 29/09/2016 at 05:07

    I’m interested in making a Samsung NX1000 3D camera rig similar to the one you made. There has been some discussion about how good the sync is on a couple 3D forums. Your water fountain sample seems to demonstrate good sync. Any idea why some have good results and others not so good?

    I’d appreciate seeing a schematic of how to wire two USB cables to a single switch (with both focus and shutter contacts). Do you suppose a wireless shutter remote control from Amazon has the necessary resistor inside with the switch and that a Y-connector to two simple USB cables would work?

  84. 17/11/2016 at 05:10

    I am trying to make a cable to twin a pair of NX1000 cameras for stereo photography. Both cameras fire from one camera’s shutter switch when a twinned wired remote is attached (it will also fire from the remote). I am trying to make a more simple cable, which leaves out the remote switch. I am taking a pair of micro USB cables, soldering the #2 (white) and #3 (green) wires together and I put a 68K resistor between the #4 (black) wire and the ground (sheathing) on each end. The #1 (red) is not used. I have also linked the sheathing (ground).
    This doesn’t work. Any idea as to why this isn’t working?

    • 17/11/2016 at 09:09

      Have you tried first with only one camera and parts for triggering one camera? One idiot-proof method would be to make two separate trigger circuits and test that they work. Then for the trigger button, get a button of 2 x on-on type. That way you would have two completely isolated circuits triggered with one button.

  85. 01/12/2016 at 19:41

    I tried making a cable for my NX500, but couldn’t get it to work. I used two 33 kOhm resistors in series, that was the closest I could get to 68 kOhm with what I had at home.
    Could that be the problem?

    I am interested in one of your PCBs. Do they work for NX500 and do you ship to Germany?

    • 10/12/2016 at 12:44

      It should be close enough, but likely what happens is that some models require focus just before trigger signal to actually trigger the camera.

    31/01/2017 at 00:24

        Hi, great project work you do. Your thesis grenade is the bomb (couldn’t help it) I too have a request for a custom trigger cable if you still have parts. I have a Samsung NX210 that I would like to use for mapping. Thanks
