Introduction: Magnetic Pumpkin Pendant

hello everyone,

today I would like to share with you a simple yet unique wearable - electronic jewelry. this post is also a very good intro to basic electronics, 3D printing and etching. halloween is closing in, here is a great night light to walk the streets, you can customize your design too.!!

Consisting of only a few parts, the project costs about $2 in material.

Here is what we will need;

1x 3V battery

1x RGB slow fade LED

2x magnets

1x 3D printed clip (must be logged in to tinkercad to view)

1x etched frame

.

let's make..>

Step 1: Etching

i have used laser cutter to etch the design. if you don't have access to a laser cutter, you can use online service ponoko - or search for a local makerspace, become a member and get making.!!

.

black color is etched, red and green are cuts. we have to use 0.125" thick material. you can also etch the design using a dremel tool, here is a good instructable for more info; instructables.com/id/Etching-Glass-With-a-Rotary-Tool/

Step 2: 3D Print

I designed the magnetic clips using free browser based design software tinkercad, it is very easy to use especially for total beginners, give it a try.!!

you can see the file here, even edit it if needed; https://www.tinkercad.com/things/8I6wWcyOEE5

Step 3: Magnets

We start the assembly by hot gluing the magnets.

.

One goes to the cover clip and the other one goes to the back-plate.

Step 4: Circuit

We have a very basic, classic first intro to electronics circuit LED + battery.

.

The light will only turn on one way, when the positive leg of the LED touches the positive + on the battery. Just turn around the battery if it doesn't light up the first try :)

Step 5: Assembly

First place the LED over the battery, making sure it turns on.

.

Then slide them together into the reserved slot

.

Magnetic clip just slides over the frame holding both the battery and the LED secure in place..

Step 6: Clip On

Now all you have left to do is to decide where on your clothing to attach the pendant.

.

put the small back clip under the clothing, while holding in place bring together the front piece and it should just snap together :)

Step 7: Conclusion

Congratulations, you are now ready to flash your wearable this Halloween.!!

.

The color changing LED has a very nice effect, you can also choose to use a regular set color LED, just make sure its 3mm kind.. Take it a step further and maybe even make ear rings the same way..

.
