She really liked it!

But after wearing it for an hour it turned out to be too heavy.

At 9 grams one earring isn't exactly light but I have seen women wear heavier jewelry. So I have to go back to the drawing board. She wouldn't let me obsess over such a thing so I have to do it in secret... again.

This time I'll ditch the prototyping look and make a proper PCB without the extra PCB the display comes with.

It also should feature a way to detect a low battery situation to prevent accidental deep discharge of the battery.

I even want it to be charged without removing the battery. The display could display the current charging state of the battery while being charged.

The content of the display should be properly randomized.
