Well, I really wanted to make my own version of a locket with leds, as seen on HaD some time ago. So I ordered some lockets as soon as I could. However, the seller did include a smaller locket as a gift…. And I couldn’t think of a use to it… Well, until I gave it a thought. Meet the ee-locket! A locket with 64k of eeprom embedded in it on a tiny PCB.
