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.

From zakqwy on Hackaday.io:

Cyborg Ring

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:

Purple Heart Soldering 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:

Blinky Octopus Necklace

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:
