“Hello everyone, this project is my first Instructables so I will try to do my best.
In this project, I will explain you how I managed to create this PCB necklace that glows in the dark ! To be honest, this is the perfect project if you want to learn about the surface-mount electronics assembly process.
First of all, let me tell you that it was inspired from this project : https://www.instructables.com/id/LED-Jewelry/ made by jiripraus so please, have a look ! When I first tried doing his project I failed terribly and I told myself “Why not use a PCB instead of using straight brass rods ?” So… TADAM this project came to my mind !!!
The initial goal of this project was to make a custom gift to my girlfriend.
On the 3rd picture, you can also see my dog, his name is Baba and I think he is wearing this necklace perfectly ^^ (He looks a little bit like Tony Stark, don’t you think ?)
Supplies:
1x Custom PCB
5 PCB for 2€
6x Multicolors SMD 1206 Led
6x SMD 0805 Resistor (a SMD resistor sample book will be your best friend in a lot of projects)
1x CR2032 battery
1x CR2032 battery holder
1x A string for the necklace
Required tools
A soldering iron
Tweezers
Soldering tin
Optional tools
