ETextile Connectable Needlework Tools: Seam Ripper

The Connectable Needlework Tools allow connecting a standard needlework tool like a seam ripper or crochet hook to the multimeter.

In eTextile work, this allows to observer the changes of electric qualities directly while working on the eTextile artefact. This instructable shows the making of a Connectable Seam Ripper. I use a standard seam ripper and a custom 3D printed handle to make the seam ripper connectable to a mini banana plug. You can use the handle also to mount another tip.

How to transform a standard metal crochet hook into a Connectable Crochet Hook is described here.

• Seam Ripper
• 3D-printed Handle (.stl file linked)
• Mini Banana Socket 2.6mm: e.g. https://www.conrad.at/de/p/schnepp-miniatur-labor...
• Cable

Remove the tip of the seam ripper from the holder.

Depending on the quality of your 3D printer, you might want to sand the 3D print to have a smooth surface.

Solder the cable onto the seam ripper tip.

Once the cable is soldered to the tip, run the cable through the 3D-printed handle. Start from the thinner side.

Push the seam ripper tip into the 3D-printed handle as well, id needed, fix it with hot glue.

The cable should protrude at the other end of the handle

Take the end of the cable to fix it to the Mini Banana Socket. You can use a little bit of solder or some glue to fix it, or wind and knot the stray metal threads around the screw.

When the cable is fixed to the screw, turn the Mini Banana Socket into the 3D-printed handle until it sits tight. The Banana Socket should close off the handle.

You can now connect the Connectable Seam Ripper e.g. to a multimeter via a Textile Cable with a Mini Banana Plug at the end. (You can get instructions on how to connect a Banana Plug here.)
