The core concept (ba dum dum) of this type of memory is that the wires (green in the photo above) weave in and out of the cores (red beads above); each wire is a binary word (in my jewellery, a character) and each bit is encoded by the wire going through (1) or around (0) the bead.
This photo made me want to have a piece of this memory to wear. It's beautiful, and I love the idea of jewellery that encodes a message. I began with beads and embroidery thread, but as I worked on the design I started to want jewellery that not only encoded a message, but could be read electronically.
The first step in that process was to make a working demonstration of a small piece of Core Rope Memory. There are a few short videos showing the working demo in this post, and you can see some of the steps along the way in posts labeled core-rope-memory. I presented the demo at Dublin Maker 2015.
I had a stall at Octocon 2015 where I sold the bead-based jewellery (amongst other things). I'm still taking orders (email contact[at]timui[dot]org), but my main focus for the project is now miniaturizing the demo so that I can make wearable jewellery that can be read electronically.
Here are a couple of photos of prototypes:
And some of the orders from Octocon weekend
I've just ordered some toroidal balloons from https://mathsgear.co.uk/ and I can't wait to use them in my display for Dublin Maker 2016!
