Does anyone know of a wiki or something of defunct fitness gadgets and their open-source life support? lf such projects exist in the world? Maybe there are things for really popular old fitness trackers but I don't think the Misfit Shine ever got much traction lol. 

I used to wear my Shine in a beautiful sacred-geometry-looking necklace peripheral and I'd check it kinda like a pocketwatch. It doesn't have a display, but it could tell you the time and your % progress to your daily step goal via tiny little LED dots around the edge. It is a svelte little thing. Swarovski even did a collab to make a crystal version plus sparkly bracelets for it. I was the target market for such a gadget and probably the only one. lol
