Nikon D90 MC-DC2 Remote Shutter Hack

Step 1: Gather the parts

go to radioshack or your parts bin and get
ONE In-Line 1/8" Phone Jack (3 PIN Stereo type)
ONE (or 2 if your making ur own shutter cable) 1/8" stereo Phone Plug
(these come in packs of 2)

one nikon MC-DC2 (works with MC-DC1 if your camera only supports that and probably other shutter releases)

Step 3: Solder and test

put the wires on solder and test
REMEMBER TO PUT THE EARPHONE JACK HOUSING IN FIRST!

solder like this

Sleeve - Black wire + metal ground housing
Ring - Green wire
Tip - White wire
solder both the jack and the plug ... the jack should be on the MC-DC2 plug side and the plug should be on the remote side to make it easy

plug them together plug it in your camera cut it on hit the button half way it should focus hit it all the way it should capture the shot

Step 4: Taking it to the next level (OPTIONAL AND NOT REQUIRED)

Picture of Taking it to the next level (OPTIONAL AND NOT REQUIRED)
so you want to take it to the next level? adding a micro-controller or logic or analog circuit?

here is a simple way to do so

it uses 2 2n2222 NPN transistors and 4 10k resistors

you can use 5-12vDC to switch the transistors and if you use a 1k resistor at resistor 4 and resistor 3 to power it off 1.5-3.3v

IMPORTENT NOTE! THE FOCUS BUTTON MUST BE ACTIVE WHEN SHUTTER IS TRIGGERED

Hi!
Thanks very much for this last (but actually not least) step! Just tried it for doing a Nikon D5100 remote with Arduino, and it works great!
In case other people would like to do the same (with arduino), remember to:
- trigger the focus first (as said above) (and leave it HIGH)
- let some time (half sec) for focusing
- trigger the shutter and leave it HIGH for the duration your photo needs
- nb: if you use the BULB mode (what i think is better to controle the speed..), remember that a shutter speed lower than (approx) half second won't work ('cause bulb is made for long exposures...)
Have fun!

my camera doesnt have bulb mode (d3100) just shutter priority (up to 30 sec). If I want to use the shutter speed set on the camera, do i still have to leave the shutter pin high for the duration?

thanks

Hi Dan, i can't be sure about it but i guess you can't tune the shutter speed from the arduino if you don't have bulb mode. I think it will use the shutter speed from the camera no matter how long you keep the shutter pin high (meaning you can use a rather short duration for HIGHing this pin)

Ok, thanks. Guess i'm just going to have to try it and see lol

Hey, I want to make a shutter release controller with the transistor circuit but I am wondering if it isn't dangerous for the camera. Like the voltage are 3.3v on mine, and don't we need to put opto isolator for security of our camera ??

Thanks

You say that the focus must be active for the shutter release to work. I am trying to connect a Celestron 4SE telescope to the Nikon (the telescope has camera control functions). Here is the schematic.

However, it only has ground and shutter release, not focus. How could I get this to work with the D3200 Nikon?

So is it possible to just buy the jack that goes into the Nikon? I have a d3100 and it's got a strange rectangular jack about the size of a mini usb, but without the flanges. It would be great to be able to not need to buy the whole MC-DC2. Is that correct? Could you maybe add a schematic of just that plug?? the colored wire description is great, but only relevant to those w/ that plug already wired up. Thanks!

Buy it on e-bay from the chinese for 3$. Buy two, just in case. When one of them breaks, you can use the plug and still use the other one.
It's far easier to just foot the cost of the whole remote shutter accessory. Once it's cut you get the plug that is broken out into the fly lead. Not to mention that you probably can't find the proprietary nikon shutter plug anywhere as a single, modifiable unit.

I cut an old usb cord I wasn't using, separated the four wires inside and stripped their ends, plugged in to my camera, shorted green against black - and nothing!
Isn't it supposed to focus when I do that?

Or is the MC-DC2 sending power through too?
The plug/socket being used here isn't the USB socket - it's the one at the top, i.e. the one above the USB socket. It's square, and a bit larger than mini USB. This applies to D90, D5000, D3100, D5100 (and possibly others, check Nikon specs at mynikonlife.com for use of MC-DC2).

You can get a cable and plug from eBay, it's a

YongNuo RF-602 YN-126 Remote Cable for NIKON D90 D5000 LS-021.

Cut one end off and you have exactly what you need. I got mine through phoebe-g2009 a few months ago for AU$7.26 each postage free, so in US$ it would be a little more.

Awesome! Thank you for this, I shoot off a 50 foot mast and needed a better way besides radio control.
