The traditional large Christmas tree was replaced by its miniature options, made from the most different materials. A Christmas tree made of LEDs looks the most festive. There are several ways to create an LED Christmas tree. The Christmas trees look different and original.
LED Christmas tree on the wall
The simplest and easiest option for making an LED Christmas tree does not require much effort. To make such a Christmas tree you will need an LED garland, push pins and photographs or small plastic toys. The Christmas tree will decorate the wall.
The buttons must be secured at the top of the spruce tree, at the ends of its legs and at their base. Mark the middle of the LED string and secure it to the top button. Next, pass both ends of the garland through the buttons, depicting a Christmas tree. You can decorate such a Christmas tree with light balls, toys or photographs. Turn on the LED garland and admire the new Christmas tree.
LED Christmas tree from a bottle
An original Christmas tree with LEDs can be made based on empty bottle from under champagne. In addition to the bottle, you will need a drill, a drill bit, plasticine, glue, LED garland and paper.
The bottle must be removed from the label and rinsed. Attach the prepared bottle to work surface using plasticine. Cover the drilling area with plasticine at the bottom of the bottle. Start drilling the hole. Once a small indentation is formed, place a few drops of water into the hole. This is necessary so that the drill does not heat up too much. Drill the hole all the way through. Remove all plasticine, rinse the bottle and wipe it dry.
Pass the garland through drilled hole and fill the bottle with it. To make the product more reminiscent of a Christmas tree, roll the white parchment paper into a cone and secure the edges with glue. Turn on the garland. Now your Christmas tree is ready.
LED Christmas tree made of floral mesh
This Christmas tree appearance will resemble a Christmas tree from under, but will look more aesthetically pleasing. To make a Christmas tree you will need floral mesh, thick cardboard, cling film, scissors, PVA glue, brush, sewing needles, LED garland and decorations for the Christmas tree.
From cardboard you need to twist a cone of the desired height. Cut the floral mesh into strips. Dilute PVA glue with a small amount of water in a container. Wrap a cardboard cone with cling film and cut off the excess. Soak pieces of floral mesh in a glue solution and apply them to the cone, fastening them with sewing needles. After the first layer of mesh has dried, lay out the second in the same way. Leave the cone to dry completely.
After this, remove the mesh cone from the cardboard structure and carefully remove the film. Place an LED garland inside the cone and decorate the entire Christmas tree with toys.

Tip 2: Two ways to make an interior Christmas tree from jewelry
Do you want to make an original interior Christmas tree that will be suitable for a room decorated in Provence style, or do you simply want not to throw away broken jewelry, but to put it to good use? Here are two simple ways make an elegant Christmas tree with your own hands for the upcoming holidays.
Quite often, beads and bracelets are torn, and the pins of brooches break off, while the clips are simply lost, and, the most offensive thing, one at a time. What to do with such decorations? Of course, don’t throw them away, but make them a very glamorous interior Christmas tree for the New Year holidays.
For this craft you will need: as many pieces of jewelry as possible, glue, cardboard, glitter for decoupage or gold/silver paint, small beads are also suitable.
Making a three-dimensional Christmas tree from jewelry
1. Roll a bag out of cardboard, glue it and cut off the wide part so that the bag stands flat and stable on the table.
2. Spread a cardboard bag with glue and sprinkle it with glitter or beads. This operation must be performed very carefully, making sure that after decoration the cardboard base is not visible. You can also paint it with gold or silver paint, but decorating it with sparkles or beads will be more impressive.
Under New Year I want to decorate my house in an original way: so that it’s not like your neighbors’, and of course, not “like last time.” With the help of LED garlands offered for sale, you can create interesting compositions, but the price of the issue cancels out the bold ones design solutions. And typical Chinese LED decorations look the same, and as a rule – faceless.
A smart solution is to create a garland with your own hands
- Firstly, it will be a 100% original product.
- Secondly, the configuration of the decoration will be exactly as you need.
- Thirdly, this is a real money saving.
- And finally, you can safely say to family members, and especially children: “Daddy can do it!”
The concept is as follows: wires are stretched from the top to the lower branches, LEDs are located at equal intervals, as if creating tiers.
The light must be dynamic: a control controller will be required. Simple LEDs shine beautifully, but point lights do not create volume. This means that lampshades are needed for each LED element.
The calculation of the garland starts from the power supply. The option is purely individual: I used an unnecessary power supply from a laptop. The estimated number of LEDs is no more than 100 pieces; when using standard 5 mm LEDs, the total current consumption (20 mA * 100) is 2 A at maximum brightness. For a series connection of 6 diodes (the voltage drop across each is about 3 volts), the power supply voltage is 18-20 volts.
General calculation of garland power supply:
We collect 5 lines. Each “thread” consists of 18 LEDs, 6 each. per channel (RGB option). 18*5 = 90 pcs., total current 1.8 A. Thus, a power supply for a laptop with the parameters: 19 volts, 4 amperes is suitable. At the same time, a double power reserve is provided.
Selection of necessary materials:
1. LEDs. I ordered red, green and blue straw hat LED elements with a dispersion angle of 120 degrees.2. . Let's look at this element in more detail. If you don’t want to waste time making your own circuit (there are many options, the cheapest of them is Arduino), you can take a ready-made controller for an RGB strip. All circuits work on the same principle: 3 controllable channels, the turn-on sequence and the brightness of the light are set. Actually, three colors are conditional here; you can connect 3 channels of identical LEDs and enjoy the lighting effects.
To power the 19-volt channels, I chose a controller with a universal voltage of 12-24 volts. The control circuit is powered by any voltage in this range; at the output we get voltage.
Required condition(for my scheme) - the presence of a remote control mode control.
3. Instead of a wiring harness, I chose (3 channels + 1 common).
4. different colors.
For ease of installation, I used 4 pin dupon type connectors (pitch 2.54 mm). The corresponding set was purchased a long time ago from the same Chinese, an excellent help for various electronic crafts.
Since I planned to hide the LEDs in the lampshades, I bought it on Aliexpress. Bore diameter 5 mm.
Calculation of connection diagram
LEDs, even when connected in series (in my case, 6 diodes), are connected through a current-extinguishing resistor. Parameters of LED elements on the packaging:
The resistor is calculated using a formula or an LED calculator. I took advantage online service:
- For the RED channel (voltage drop 1.8-2.0 V) resistance is 420 Ohms.
- For GREEN and BLUE channels (voltage drop 3.0-3.2 V) the resistance is 82 Ohms (green) and 75 Ohms (blue). The green LED element shines brighter, so the resistor has a higher value to equalize the overall picture.
I bought a controller for RGB LEDs with a common anode. That is, a minus is supplied to each channel, and a plus is supplied to the common wire.
Assembling the garland
You can use twisted wires, like on factory garlands. I liked the design on the train better.
We make a reinforced leg for each LED element. To do this you will need toothpicks and heat shrink.
We assemble and warm it with a hairdryer.
This results in a design like this:
It makes sense to immediately prepare and test all 90 LEDs.
Then we mark the cable, determining the installation locations of the diodes at equal distances. I made neat cuts along the cable on the wires. desired color, cut and tinned the installation sites.
After assembly, each LED looks like this:
It turned out neat and reliable.
It is convenient to solder on a device with a magnifying glass, which is called the “third hand”.
Next, we connect the supply wire (common “+”) to the channels through resistors.
We insulate the parts with heat shrink.
And connect it to the “plus”.
We cover this loop with large diameter heat shrink.
We mount connectors on the opposite end.
Then we put snowflake lampshades on the LEDs.
The task is not easy (after all, 90 pieces!), but exciting.
Let's check again. The effect is amazing.
Note: Working LEDs do not look good in photographs, so the image is significantly worse than the original.
All that remains is to mount the garland on the Christmas tree and invite the children to admire their father’s work.
Result:
The total financial costs for the garland are no more than 1000 rubles. The main consumable part is the finished controller. The power supply is shareware. Diodes and wires cost mere pennies. Additional costs: 300 rubles for snowflake lampshades. The option is not mandatory, but it significantly increases the attractiveness of the garland.
I don’t regret the time spent (4 full weekends): it was interesting to work, and the result is worth it.
DIY LED Christmas tree that does not require programming!
This project shows how to do Christmas decoration in the form of a Christmas tree without much effort and knowledge. Christmas tree has a size of 120 x 80 cm and is made of ordinary LEDs, but their operation does not require a microcontroller and its programming at all. This means that everyone can do it.
The project doesn't take that long to make, even though it contains almost 1,500 individual LEDs. It is assembled quite quickly and simply, but this is taking into account that you will follow the instructions given below, which will contain warnings against various errors. Before starting assembly, it is recommended to watch the video presented above.
Step 1: Materials and Tools
To make this project, you really don’t need as many materials and tools as you might initially think. This makes the project cheap and easy to make. So, you will need:
Materials:
- LEDs 5 mm. This project used almost 1100 green, 300 yellow and 100 blue LEDs. Moreover, the yellow and blue LEDs should be blinking.
- MDF or fiberboard sheet
- Soldering materials
- Electrical wires, about 30 meters, preferably made of thin, solid copper conductor. IN in this case a split telephone cable was used.
- An old laptop charger as a power source, in this case we used an 18.5 Volt power supply with a power of 4 Amps.
Most main secret in this project is to have individual colors of LEDs flashing. In this project, these are yellow and blue LEDs. When designing, it was assumed that they would flash at different intervals, causing a random pattern over time, and this theory turned out to be correct. The moment power is applied, they start blinking at regular intervals, but after 10 - 15 seconds, they start blinking randomly. If we take into account this feature of non-uniform operation, it turns out that to create a beautiful effect, no microcontroller, no programming, no resistors, no capacitors, or anything other than LEDs are required!
You will also need very few tools:
- Drill bit diameter 1mm and 5mm, drill
- Soldering iron
- Wooden model - matrix
- Insulating tape
- A tool for stripping wires (as it turns out, the most important one, since it greatly simplifies the work).
- Ruler, pencil and other small things.
Step 2: Preparing the design
Prep takes about half the time to make this project, and trust me, it's worth it.
First, you need to draw an image on graph paper (you can use graph paper), using only the colors of the LEDs that you can find. Be careful with red because... in this case, 100 red flashing LEDs were ordered, and it turned out that when they are combined into a series, they turn off the entire series at the same time and do not light up again (it looks ugly and is not recommended for you). By combining red LEDs in a series of 9 pcs. they practically did not catch fire. Blue and yellow LEDs are not affected by this problem, so we had to exclude red LEDs from the entire project.
In this project, the image was initially created in Photoshop program, but this turned out to be quite a difficult moment. After searching for similar programs on the Internet, many software products were found that decompose images into square pixels. There are a lot of them, and it’s up to you to choose which is more convenient. The essence of this step is to divide the image by color into squares of a certain size. Then print it on paper.
The next step is to properly orient the LEDs to reduce physical coupling. It would be possible to simply orient all the cathodes in one direction and the anodes in the other, creating a kind of square mask by connecting the power to only two poles, but in practice this turned out to be very inconvenient. Therefore, the connection diagram in this project looks like connecting rectangular areas, since this does not require the presence large quantity additional resistors to reduce the voltage supplied to the LEDs, and at the same time reduces the current consumption.
From the technical description of the LEDs, it was found that each LED has a voltage drop of about 2.5 Volts. In order to completely eliminate the use of resistors, it was decided to combine LEDs in a series at the rate of 18.5 Volts / 7 pcs. = 2.6 Volts (LED voltage drop). Thus, one series of LEDs should contain 7 LEDs and at the same time they will glow at maximum brightness.
In our case, we used a template with squares, in the center of which there was a dot of a certain color. Then, on paper, each color was combined into a series of seven LEDs. It was a very tedious task, but fun in its own way, almost like solving a puzzle. As it turned out in the end, a series of 7 LEDs was not enough to withstand a voltage of 18.5 Volts, so in the end the series had to be increased to 9 LEDs. We strongly recommend that you find out and accurately calculate the permissible voltages for one series. This will save you from redoing the entire circuit again.
Step 3: Jig Soldering (LED Series)
To make life easier, a small matrix was made. Using the same dimensions as for final assembly, a small wooden board was made with a pitch of 5 mm between points. When applying this matrix to a sheet of MDF or fiberboard, it must exactly correspond to the drilling holes. After marking the holes, it is recommended to mark the row and column numbers, this will further simplify your further assembly. Also, on this matrix, in the next step, separate series of LEDs will be assembled, which will then be inserted into the main template.
Step 4: Create Custom LED Series
Now, if you have a convenient template for creating series of LEDs, you can proceed to the next step. We must start from the very beginning, i.e. from the first episode. Place the LEDs of the first series in the required order. Some of the LED legs must be shortened, otherwise they may cause short circuit. Then straighten the legs of the LEDs so that you have a serial connection (i.e. plus the previous one with the minus of the next one, etc.). To mark the series, small pieces of adhesive tape were glued with the series number on the anode of the last LED, and the minus was not indicated in any way. After assembling the series, it is checked for functionality, if everything is fine, then you can move on to the next series. This project produced 150 series of LEDs, the work is very tedious and requires attention. Don't forget to check connections after soldering.
Step 5: Preparing the fiberboard
The MDF sheet that was purchased for this project was the perfect size so there was no need to trim it. If you have such a need, then cut the sheet to the required size.
Draw a square grid across the entire sheet, but first make sure that it matches the grid you used to create the LED sections, i.e. corresponds to the preliminary matrix. Be careful if you break the square matrix a bit, i.e. Draw lines that are not perpendicular, it can ruin your entire project!
Then, using the square template drawn on the paper, identify the circular areas in which you need to drill holes. These are not exact areas, they are only needed to understand the outline of the figure. Then mark the exact points for drilling holes.
After this, to make the holes easier to drill, drill all the holes with a drill with a diameter of 1 mm, and then go through all the holes with a 5 mm drill. This step is quite time-consuming, it took approximately 7 hours to drill 1500 holes!
Another extra hour was spent sanding various irregularities and removing burrs.
Step 6: Installing LEDs into MDF Board
This step is quite simple, but again, if you have exactly the same dimensions of the preliminary matrix and the holes drilled in the MDF sheet. If everything is accurate, then simply insert the LED sections from the back of the MDF sheet into the drilled holes, according to the paper map. Ideally, you won't need any fixation for the LEDs.
Be careful when inserting LEDs into the holes; if the distance is slightly off, there is a chance of damaging the LED lens or pin soldering. Also, don’t rush to remove the tape with section numbers, it will come in handy later!
Step 7: Create Positive and Negative Power Rails
To create power buses, you need to take a regular wire that is used for a voltage of 230 Volts (for example, the cores of a PVA wire), strip it of insulation, and twist it well to avoid delamination of small wires. Each side will require approximately 150 cm of wire. Then secure each of the cores with reverse side MDF sheet, for example, with plastic staples, on both sides of the sheet vertically. Where the lines of the squares intersect, the wire must be tinned for further soldering (in this case, there were about 60 points on each side).
At this step, when all the LEDs are in place, clearly determine where the series is plus and where it is minus. The order in which the sections are connected does not matter.
Start from the bottom row. Solder all sections one by one to the positive and negative power bus. In order to save time, wires and the number of soldering points, consider the possibility parallel connection sections - this will significantly save your time and effort. Remember that the wires for connecting to the power buses must be insulated, otherwise a short circuit will occur!
It is recommended to connect line by line, this will greatly help you if you make a mistake. Also, if you wish, you can add to the diagram regular switch for power supply between the charger and the LED tree; in our case, the project works simply by connecting the power supply to an outlet.
This concludes the production of the project, but remember that this idea is suitable not only for depicting a Christmas tree, you can also implement your own, completely different, ideas.
In addition to the traditional Christmas tree, your home can also be decorated with miniature versions of the New Year's beauty. To make them look no worse and also please the eye, you can use LED garlands to make them.
The traditional large Christmas tree has been replaced by its miniature versions, made from a variety of materials. A Christmas tree made of LEDs looks the most festive. There are several ways to make an LED Christmas tree with your own hands. The Christmas trees look different and original.
LED Christmas tree on the wall
The simplest and easiest option for making an LED Christmas tree does not require much effort. To make such a Christmas tree you will need an LED garland, push pins and photographs or small plastic toys. The Christmas tree will decorate the wall.
The buttons must be secured at the top of the spruce tree, at the ends of its legs and at their base. Mark the middle of the LED string and secure it to the top button. Next, pass both ends of the garland through the buttons, depicting a Christmas tree. You can decorate such a Christmas tree with light balls, toys or photographs. Turn on the LED garland and admire the new Christmas tree.
LED Christmas tree from a bottle
An original Christmas tree with LEDs can be created using an empty champagne bottle. In addition to the bottle, you will need a drill, drill bit, plasticine, glue, LED garland and parchment paper.
The bottle must be removed from the label and rinsed. Secure the prepared bottle to the work surface using plasticine. Cover the drilling area with plasticine at the bottom of the bottle. Start drilling the hole. Once a small indentation is formed, place a few drops of water into the hole. This is necessary so that the drill does not heat up too much. Drill the hole all the way through. Remove all plasticine, rinse the bottle and wipe it dry.
Pass the garland through the drilled hole and fill the bottle with it. To make the product more reminiscent of a Christmas tree, roll the white parchment paper into a cone and secure the edges with glue. Turn on the garland. Now your Christmas tree is ready.
LED Christmas tree made of floral mesh
This Christmas tree will resemble a champagne bottle Christmas tree in appearance, but will look more aesthetically pleasing. To make a Christmas tree you will need floral mesh, thick cardboard, cling film, scissors, PVA glue, brush, sewing needles, LED garland and decorations for the Christmas tree.
From cardboard you need to twist a cone of the desired height. Cut the floral mesh into strips. Dilute PVA glue with a small amount of water in a container. Wrap a cardboard cone with cling film and cut off the excess. Soak pieces of floral mesh in a glue solution and apply them to the cone, fastening them with sewing needles. After the first layer of mesh has dried, lay out the second in the same way. Leave the cone to dry completely.
After this, remove the mesh cone from the cardboard structure and carefully remove the film. Place an LED garland inside the cone and decorate the entire Christmas tree with toys.
