Mahesh Venkitachalam has created wondeful LED Earrings with the Lattice iCE40UP5k FPGA and shared the project on our website:

iCE Bling FPGA – Beautiful LED Earrings with Lattice iCE40
It’s the same story every year. At the horizon is a loved one’s birthday, or an anniversary, and I want to make them something special. Buying something won’t do. Oh no, I have to design and build it myself. I would then start with a simple idea, and then complicate it progressively to the point where it would take several anniversaries to finish the project.
This time, I wanted to build a pair of earrings for my wife’s birthday. Since I am learning about FPGAs these days, I wanted to incorporate one into the design. Having gotten older and wiser, I decided to enlist help early on. I would focus on the overall design and the programming part, and leave the PCB design and assembly to my trusted friend and engineer Siva.
Alex Glow from Hackster posted an update on the Charmware modular tech jewelry system:

Sweet, a package from OSH Park! Time for an unboxing! Plus, see how to upload and order your own boards.

From zakqwy on Hackaday.io:
cordwood + smt + jewelry + blinkies + zinc-air batteries
This project evolved from Splinter, the SMT cordwood project I did last summer/fall. The ring is powered by tiny size 10 hearing aide batteries which should give 4-6 weeks of intermittent use, once I come up with a design that doesn’t break after a few days of wear and update the firmware to put the ATtinyx5 to sleep. The first rev (labelled ‘blink-ring’) used deep red 650nm LEDs. Searching for particular component lengths gave me an excuse to use strange 0508 resistors. And somehow, this is my first Charlieplexing project. Yaay novelty soldering!
We love PCBs, so we were excited to see this beautiful circuitry from Lumen Electronic Jewelry:
Fashion Gets Geeky
Lumen is the creation of Robin and Marty Lawson in Madison, Wisconsin:
We’re life-long tinkerers, siblings, and fourth generation mechanical engineers.
They’ve designed soldering kits for all levels: beginner, intermediate, and advanced surface mount soldering. This heart is an example of an intermediate kit:
Lumen also makes beautiful fully-assembled LED jewelry:
Solar powered twinkling LED jewelry. No batteries, hours of blinky.
We particularly like this twinkling fiberglass cephalopod:
Each octopus has 16 amber LED lights throughout the arms connected to 12 tiny solar cells. So your necklace will charge and blink all on its own, no batteries required.
Robin tells me that they use Free PCB for layout:
Robin informed me that they laser their own stencils out of thin mylar sheets at their local Makerspace, Sector 67:
They then bake the board in a toaster oven:
Robin explains that afterwards they clean the boards in an orange -based degreaser then seal in a ResinLab epoxy
It is expensive but has a long working life, excellent hardness and optical clarity, as well as UV resistance to yellowing.
P.S. Here’s an insightful talk that Robin gave at TEDxMadison last year:
