NEX-5n Intervalometer for time-lapse photography

Before I got my Sony NEX-5n I was aware that it lacked a method of doing time-lapse built in. The remote was also lacking this feature and there were few third party devices that could do this. I had seen some methods of doing this by adapting the remote to include an intervalometer. So after purchasing the NEX-5n I set about making my own but with an improvement, I wanted to be able to remove the intervalometer from the remote so that I could still use them independently.

Note: this can also be used for Sony NEX-3, NEX-C3, NEX-5 and Alpha series

What I needed:
Opteka RC-3 Wireless Remote Control for Sony
NEEWER® Timer Remote Control RS-60E3
2.5mm Female to 3.5mm Male Headset Adaptor

First I had to open the remote. While it looks like the plastic splits apart, it does not and the face peels of like a sticker. It's easy to push it up from slit that the battery came out of.

Slowly peel off.

Remove screws from circuit board and pull it all apart.

  I cut off the male connector of the headset adapter and exposed the wires.

Drilled a hole in the back cover of the remote.

Using a multimeter I found the two connections on the intervalometer that would trigger the switch. I then found that the two colored wires on the headset adapter corresponded to the right connections on the intervalometer. I traced the connections from the shutter switch on the remote to the back of the board then threaded the wire through the hole and soldered it on to the circuit board.

Carefully reassemble and add a dab of glue to prevent the wire being ripped out.

And that's it. Now just plug in the Neewer timer remote and have fun!
