Fashion a Mold to Cast Your Own Canon Shutter Release Cable Connectors


Here’s something that may not be relevant to most of you, but if you enjoy dabbling in do-it-yourself gear hacks you might find it interesting. Milan-based photographer and freelance engineer Andrea Biffi came up with an interesting way of creating a shutter release cable connector for his Canon DSLR. Instead of buying an actual remote and slicing off the plug end, he decided to cast his own out of hard rubber.

Instead other more commonly used connectors, Canon chooses to use a special 3-pin, snap-in connector called the N3 connector on many of its newer DSLRs.

To make it easy to cheaply recreate this N3 connector, Biffi create a mold.

After purchasing a single cheap Canon remote as a reference, he stuck three wires into the three holes in the remote’s connector.



He then stuck these wires and the plug into a clump of Sugru silicone rubber, and allowed it to harden. Once the mold is firm, you can pull out the connector, leaving the three wires behind.



You then take three wires with female connectors, stick them onto the three wires in the mold, and then pour resin or rubber into the mold to create the new connector.


The resulting shutter release connector and cable isn’t the nicest looking thing, but it’s cheap and definitely DIY.


This same concept can also be used for all kinds of other similar connectors you may come across in your DIYing adventures.

If you’d like to actually try this connector casting for yourself, you can find Biffi’s detailed step-by-step instructions over on Instructables.

    you can get useless opinions for free on the internet.

    this is interesting, there are other uses for this technique.

    Guess that most people that have a new camera won’t do this but it’s not just new expensive cameras that have this connection. Earlier version of Canon EOS XXD (10D,20D,30D,40D and 50D) uses this N3 connector.

    I have a 60D myself and it’s use the 2.5mm mini-plug and happy it did since I wen’t from an 450D.
