Hi All,
Few months back I came across an instructable https://www.instructables.com/id/LED-Jewelry/ by jiripraus
I wanted to try the making one, for my wife and she wanted a Star shaped LED jewelry. I did a google and could not find any template for it. So I decided to make one myself
In this instructable I will share how to design and make your own led jewelry
What Do We Need ?

- Brass wire 21 Gauge ( approx 0.9mm)
- LED Strips ( white ) or smd LEDs
- CR-2032 battery
- Soldering iron
- Paper tape
- one A4 Sheet
- Pencil, compass, and a measuring scale
- Cutter
- Pliers Small
- Multi-meter
SMD LED

- I extracted my LEDs from an old LED strip
- These were white SMD LED
- Approx 3 mm X 2 mm X 1.5 mm ( L x W X H )
- Had a T sign on it which indicated the cathode for the LED
- Carefully de-solder these leds from the strip
- I needed 6, but i extracted 9 of these, just to be sure that I had enough to work with
- Test the LEDs to make sure they are still working, replacing LEDs later is bit difficult
Design Principles
![IMG_20191201_194059-01.jpeg](/proxy/?url=https://content.instructables.com/FY8/QHKG/K3NKMH9U/FY8QHKGK3NKMH9U.jpg&filename=IMG_20191201_194059-01.jpeg)
- The jewelry has to be as compact as possible, we need to use the smallest battery avaliable
- We are not building a torch, do not use extremely bright LEDs
- Joints should not have sharp edges
- It should look simple and elegant
- Measure the battery, LEDs and wire
- My Battery was 20 mm in diameter
- The star is made with a circle with 40 mm diameter, one could chose to make it more bigger depends on one's preferences
Star Outline
![IMG_20191201_201226-01.jpeg](/proxy/?url=https://content.instructables.com/F7P/SDG2/K3NKMHBB/F7PSDG2K3NKMHBB.jpg&filename=IMG_20191201_201226-01.jpeg)
![IMG_20191201_201326_1-01.jpeg](/proxy/?url=https://content.instructables.com/FZ8/A03F/K3NKMHBG/FZ8A03FK3NKMHBG.jpg&filename=IMG_20191201_201326_1-01.jpeg)
- Trace the outline with brass wire
- To get better star shape we have to cut the brass wire as shown and then soldered the joints
- Stick the wire in place using paper tape
- Remember to file the joints, so that there are no sharp edges
Add LEDs
![IMG_20191201_202355-01.jpeg](/proxy/?url=https://content.instructables.com/FIA/RYK5/K3NKMHD6/FIARYK5K3NKMHD6.jpg&filename=IMG_20191201_202355-01.jpeg)
![IMG_20191201_203316-01.jpeg](/proxy/?url=https://content.instructables.com/FRZ/SAUE/K3NKMHDE/FRZSAUEK3NKMHDE.jpg&filename=IMG_20191201_203316-01.jpeg)
![IMG_20191201_203328-01.jpeg](/proxy/?url=https://content.instructables.com/F9H/UDR9/K3NKMHE4/F9HUDR9K3NKMHE4.jpg&filename=IMG_20191201_203328-01.jpeg)
- The Star outline will be connected to positive end of the battery
- So solder anodes of all 6 LEDS to the star as shown
- Add joints to connect all cathodes of 6 LEDs as shown
Add Hook
![IMG_20191201_203709-01.jpeg](/proxy/?url=https://content.instructables.com/FO2/85KA/K3NKMHEW/FO285KAK3NKMHEW.jpg&filename=IMG_20191201_203709-01.jpeg)
- Since this is a going to be a pendant, We need a hook
- Twist and cut a small hook of brass wire
- Solder it flat to the star
Battery Support
![IMG_20191201_205030-01.jpeg](/proxy/?url=https://content.instructables.com/FPO/P6VR/K3NKMHG2/FPOP6VRK3NKMHG2.jpg&filename=IMG_20191201_205030-01.jpeg)
- On the back , we will add two battery supports to hold the CR 2032 battery in place
- one of the support is as the diameter and another at the bottom
Finishing
![IMG_20191201_205116-01.jpeg](/proxy/?url=https://content.instructables.com/F5X/VIGC/K3NKMHHL/F5XVIGCK3NKMHHL.jpg&filename=IMG_20191201_205116-01.jpeg)
- Inspect the LED jewelry for week joints and add soldering where needed
- Remember to file the joints, so that there are no sharp edges
- Insert the battery and test all LEDs
- Hook it in a chain and we are done
I hope this instructable will inspire you to design your own shape and make one
thanks for reading
