Luminescent Artist Palette Earrings: Wearable LED Color Sculptures - Rechargeable

Luminescent Artist Palette Earrings: Wearable LED Color Sculptures - Rechargeable
I am designing a matching pendant on the left side for the Fibonacci earrings on the right. The pendant is using PWM outputs to the LEDs, allowing a much smoother animation. You can clearly see the "frames" on right side, while the left has a much smoother transition for the same pattern and speed.

Such a nice alternative to the coin cell battery holder!
Hey soldering kit makers! Struggling with new coin cell regulations and have a pile of PCBs with coin cell battery holder patterns on them? I made a thing for ours that converts them to USB power, maybe it's handy for you. 🧵

The art palette earrings now use a supercapacitor instead of coin cell batteries.
They are designed with two components: main board and "face plate". A recent prototype with a ceramic face plate turned out well. I'm leaning towards using a PCB for the front due to its practicality and durability.

I made these GlowCaps! They let you easily add RGB LEDs to things like candle holders or light up your fursuit. They're powered by a supercapacitor, so they charge in just minutes and can run for hours or even days.

Exploring the interplay of love and mathematics, especially in the spirit of February, the month of Valentines, the Amoracci pendant is a visual meditation on the beauty of these interconnected concepts. Its design is inspired by the Fibonacci sequence. #Fibonacci #JewelryDesign #Love #Mathematics

My hand drawn circuit talk i'll talk a little bit about anwaar which will cover some of my use of Hybrid caps! @californiasteam.bsky.social has done wonderful jewelry work with hybrid caps and a lot of the tech we use overlap. If you're planning on going to #teardown2025 def consider these talks!
Also, my battery talk is going to dovetail nicely with @californiasteam.bsky.social 's talk on using supercapacitors in jewelry designs, and @chipperdoodles.bsky.social may have some cool stuff to share about hybrid capacitors too! So much good info to dig into. Let me know if you plan on coming! 👇

These Fibonacci earrings are a little bit different. These have ultra-bright LEDs, each enhanced with a focused lens.
The earrings have 104 LEDs per side, which can be programmed to display a variety of patterns, brightness and speed.

How much charge does a 15F Hybrid supercapacitor actual hold? Here is a graph of data taken with the NRF Power Profiler that shows that the charge in this 15F capacitor was 15.2c from 3.8V down to 2.8V, which exceeds the specifications.

Check out these unique PCB designs!
Working on an article involving PCB art. Anyone have great examples (or even just examples) that you'd like to share and that I can potentially include?

My journey with wearable electronics began with these small red LED spiral earrings – 12 LEDs, a microcontroller, and a coin cell battery. Today, I'm pushing the boundaries with designs featuring up to 104 LEDs, still powered by a microcontroller, but now utilizing a supercapacitor instead.

Just love how these small LED strips now allow you to add 2D to a small surface like a headband!
Found a 2.7mm thin Neopixel strip with a silicone coating and decided to cram as many rows as would fit (5) onto a headband. Added a Pixelblaze Pico controller and an off the shelf holder for an AA-sized Li-Ion battery. I intend to be "light headed" for the holidays!

Here's the WIP. Still gotta finish up the front and clean up the back but i'm very excited about this one!!!

Lithium-ion capacitors (LICs) are a special kind of supercapacitor. Typically, they have a voltage limit of 3.8V, but recently, I discovered a new type that can handle up to 4.2V! This voltage increase can significantly boost their energy storage capacity by tripling it.

The subdued glow of the purple/UV LEDs on these Fibonacci tech earrings lends a touch of magic, transforming the environment into a dreamlike realm.

You might have noticed that none of my wearables use current-limiting resistors for LEDs.
Do LEDs really need current-limiting resistors?

My rechargeable Fibonacci earrings with supercapacitors remain one of my biggest accomplishments. It's a project that truly combined my love for math, technology, and design. Fully charged in a couple of minutes and run times up to 20 hours from a single charge.

Are any of you experiencing issues with USPS tracking lately? My packages aren't getting scanned until they reach the destination, making it impossible to track their progress. Wondering if it's a widespread problem or just me.

For the first LED wearable with a supercapacitor, I incorporated a 20F, 3.8V max LIC supercapacitor into my design.
By meticulously optimizing the code that controls the LEDs, I managed to achieve an incredible 30 hours of continuous illumination on a single charge!
