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
wireless charging kit. I got one set that is Chinese made at 13USD from aliexpress.
3D printed custom made jewellery to hold the electronics, rx loop, and fiber optic. I have chosen to use a 3D printed bangle. The STL is available here. Print it twice. The two halves are snap fit. It was done in sketchup with the help from xinteng from DCPE yr1.
An apparatus with RGB LED fading PCB of some sort, which consist of a microcontroller such as Arduino or ATTiny85, a RGB LED and a custom PCB or veroboard. A tutorial to program ATTiny85 with Arduino is available and the necessary ATTiny ISP shield can be made too.There are many derivatives floating on the Internet. I have used my own recipe of ATTiny85 with RGB. The step by step guide of “cooking” a PCB of your own is available here.
