KdN - Kokes dot Net - LED Ring
Rohit Khare stashed this in potpourri
Once upon a time, a boy met a girl. Then a short amount of time later, the boy decided to design and build a ring for the girl, because doing things in the most complicated way possible is just what he does to show the love. This is that story.
It starts off in Jan of 2013 where the idea for the ring was refined to what will ultimately be the final form. Several designs were considered and were rejected because of exotic material requirements, machining geometry limitations or violating the laws of physics. It was a fun exercise to explore potential and unique designs, but at the end of the day, I still needed to make her something that I could present and that didn't look like it was carved with a spoon.
The final idea was to embed a LED and copper coil assembly inside the titanium ring, illuminating it from under the stones when it was in close proximity to an induced alternating magnetic field (henceforth called 'the transmitter').
Extraordinary ring. Seriously.
