About: Tecnical Teacher

Hi makers, we are here again with a beautiful and stylish lamp Project. VORONOI HEART LAMP. In this project, we benefited from epoxy resin material and 3D printer.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: What Is VORONOI ?

In mathematics, a Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points (called seeds, sites, or generators) is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. These regions are called Voronoi cells. The Voronoi diagram of a set of points is dual to its Delaunay triangulation.

Step 2: What Is EPOXY ?

Epoxy resin is known for its strong adhesive qualities, making it a versatile product in many industries. It offers resistance to heat and chemical applications, making it an ideal product for anyone needing a strong hold under pressure. Epoxy resin is also a durable product which can be used with various materials, including: wood, fabric, glass, china or metal.

So we think about Voronoi heart. We designed it as a lamp. There is no more materials. You will find them easly. In this project, we are using just Arduino Nano, a resistor and a red led. That’s it. After you have a Voronoi heart lamp, use it yourself or give it to your loved ones. We bet they'll certainly like it.

Step 3: Materials

We need some electonic and printable materials . As you can see in pics;

- Arduino Nano

- Red Led

- Voronoi Heart

- Boxes

- Epoxy Resin + Hardener

Step 4: Making Epoxy

Firstly, we are starting with epoxy. we need resin and hardener. we have 100%. 20% Hardener + 80% resin.

Step 5: Assemble Voronoi Heart and Led

We are soldering the led legs. and than we put it into the voronoi heart. as you can see pics.

Step 6: Filling Epoxy

now we have voronoi heart with led. We are putting it in a box. This box will be a mold. Than we will split them for epoxy.

NOT: please wait min 2 days for drying epoxy. This is important

Step 7: Split and Sand

we are splitting and sanding now. As you can see in pics.

Step 8: Again Epoxy

Step 9: Electronic Connections

Connection is simple. Just need a few materials.

Step 10: Results

And results.

    I made something similar for my wife for Valentine's Day. I wrote an Arduino sketch that pulses the heart in a realistic way -- I grabbed real data from an EKG! Let me know if you want to try it out on yours.

    Hehe : D yes you can make it with EKG or pulse sensor.

    I believe when working with epoxy, if you hold the cup higher and pour in a very thin stream, you will pop and break most of the bubbles in the epoxy from the mixing process. That would likely give you a clearer cast. Of course if you prefer the bubbles as an effect, what you have is excellent.

    Hi RBRBRB, thanks for your advice. I will care next time...regards


    Question 7 months ago

    What is the purpose of step 8? Is it to have a clear finish without having to use finer and finer sandpaper?
    For clarity, moreover, I'd invert steps 4 (Making epoxy) and 5 (Assemble Voronoi Heart and Led), since you have a limited time to pour the epoxy (and so it is better to have the heart already assembled before mixing the epoxy)

    Hi frarugi87, about 8 , yes most clear. if you have better solution, share with us. I can try it.
    and second issue. This is a not a rule. You change steps. :D
    Thanks for comment

    Very cool, Congrats! Fun idea is to use Pulse Sensor with arduino for showing in live your heart :)
