Valentine's Day 2013 is coming, LED engineers make romantic gifts by hand

After I bought 150 LED lights, the switching method of those lights when they were working attracted my attention, which inspired me to make a screen that can change the display of text, pictures and other effects. Finally, I designed it as a front and back dual-screen device, the effect is shown in the figure.

Step 1

First, I need to print out what I want to engrave on the plexiglass board. In this case, it is my friend’s name. I engraved her first name on the front and her last name on the back.

Step 2

Then use a marker to draw a preset pattern on the plexiglass plate, then turn the glass plate over and draw a picture on the back of the glass plate (the side without the film).

I also found some reference text for this, so I did the same thing. I don't know why, but in reality, when the board is lit, the engraving effect on the back is much better than on the front.

The carving effect is better.

Step 3

Start carving (I'll talk about the tools here. The author uses a mini punch drill, which is usually equipped with a special head for grinding, or a broken drill bit, or a long drill bit.

It is easy to break, the hardness of the plexiglass plate is not too hard. Friends who don’t have a drill can try other tools).

 

The picture shows how I fixed the plexiglass plate, and in this way there is enough space to install the LED. The material is MDF (MDF is translated as medium density fiberboard, which is

Composite material boards (with varying densities, commonly used for amplifiers, cheap, and easy to cut), or similar materials.

 

Step 5

The next step was to install these LEDs in the limited space. I only had 96 LEDs available at the time, so I found an MDF board to punch the corresponding holes.

Step 6

After inserting 96 LED beads, it doesn't look very beautiful, but it works very well. The beads are arranged neatly and perfectly correspond to the glass plate.

 Step 7

Finally, use a fiberboard as the base and assemble all the previous parts together.

Step 8

Effect picture:

As you can see in the picture, the display is changeable, and readers can make different effects according to their needs. These materials are easy to find in daily life, and it is not difficult to process them. Some people even carve complex patterns or add color changes on the original website, which makes the effect more dazzling!
