Wireless powered bling diffused with sideglow fiber optics : Project you are the ONE

Project you are the ONE. a Wireless powered fiber optic side glow diffused bling

I have this idea of making novelty jewellery for my missus, a wearable electronics of some sort with wireless charging.

At a seeming random event I would have a little girl present her with a nicely decorated box containing the bling I have made, with a message asking her to “follow the rabbit”. Hopefully the intricate design would be tempting; she would put on the jewelry I made without hesitant. A rabbit inspired human would walk pass her and hopefully she would pick up the subtle message of "following the rabbit" per se. While following the rabbit, she will come across a few interesting characters that are staged, and the last person to appear will be yours truly.

Naturally, we would reach out to each other. Me, being the techie would have the inductive charger's transmitter loop well hidden in my palm; the circuitry is hooked up to a cleverly disguised 12v 1A power supply.

It is just a matter of time/distance for the EM fields resonating between the tx loop and the rx loop; her novelty jewelry will light up mysteriously, and the intensity of the light grew greater as we are moved closer! YES!! You are the one! Both of us proclaimed. Well, that’s the perfect time for yours truly to take a knee with a unique ring and what else?? Propose to her!! This definitely work. Trust me, I am an engineer.

Coupling several technologies and digital fabrications technologies: wireless charging (inductive charging), Arduino, ATTiny85, RGB LED, PCB, and fiber optics. i present to you the said piece

Oh waittttttttttttttttttttttttttttttttt…………I don’t have a missus/wife/GF yet.

This instructables assumes the following parts

1x DIY wireless charging kit, acquired from aliexpress

1x RGB LED fading PCB

1x 5mm side glow fiber optic with sufficient length for the applicaition

1x bespoke 3D printed holder as the jewellery

1x 12v 1A DC supply

You really need to put some stress relief on the LEDs leads, if you don't the solder joints will crack.. A little bit of hot glue would work..

spot on. This is just a quick and dirty prototype to support the story i made up.

Cool idea! How much current does the light assembly draw when active? As an improvement thought, what about installing an aluminum capacitor to hold some of the charge, so the led stays lit for some period of time when you take it away?

I have not measured the current draw at the rx loop; judging from the intensity of the LED (with a 220ohm resistor), i would say a 20mA or so.

Can you share the link where you bought the wire?

aliexpress. lookup for "diy wireless charging". FYI, I am not affiliated with any of the vendors. I am just a consumer.

what is missus, out of sudden? fun story however please proof,spell check before asking for her hand in marriage:) - but adorable story

shinteo (author)  milestones1 year ago

my apologies. I have rephrase and spell check to increase the readability of the story i made up.
