LED CUBE 8X8X8 PROJECT PDF

In this project, we will see how to build an 8x8x8 LED Cube. There are many projects based on the 8x8x8 LED Cube and some of them became. 8x8x8 LED Cube Driver If you take a look back at the schematic you will see it is basically split in half. The right hand side is for the individual LED driver and the. 8x8x8 LED cube powered by an arduino. GitHub is home to over 28 million developers working together to host and review code, manage projects, and build.

Ever heard of an embedded electronic project called LED cube? Actually, this project had been done by many embedded electronic hobbyists due to its interesting display effects by lighting up LED Cube in certain patterns.

The LED Cube lighting patterns can be controlled by microcontroller based on the program loaded into it. In this tutorial, user lrd be projecy to build up a 8x8x8 LED Cube in step by step. The resulted LED Cube from this tutorial will be looks similar to picture below: The resulted LED Cube.

Building An 8x8x8 LED Cube

Few pictures when the resulted LED Cube light up are shown below. A short video demonstrating available lighting mode of the resulted LED Cube is shown below. Note of the projevt All cathode legs of LEDs in a particular layer will be soldered together. The cathode for a particular LEDs layer can be activated shorted to ground by turn on the transistor connected to it. Untill now, it is believed that users have know some basic principles of working of a LED Cube. Its appearance will be similar to picture as shown below.

The top and bottom surface of a new acrylic sheet should be covered with thin light brown sheets for protection. Please do not remove these thin brown sheets.

By using the blank side of acrylic sheet, starts draw frame lines based on the dimensions as shown below by using pencil and L-shaped ruler.

Next, draw vertical lines which are parallel to the reference vertical frame line with the separation distance 2. There are total 7 of them.

Draw cune lines parallel to the reference vertical frame line. Then, draw horizontal lines which are parallel to the top reference horizontal frame line with the separation distance 2. There are total 6 of them since the eld horizontal line is already drawn, which is the bottom reference horizontal lines. Draw horizontal lines parallel to the top reference horizontal line. Why the holes for the mold must be drilled with distance 2.

Super bright 3mm blue LED with its cathode leg bent 90 degree. The separation distance of 8x8s8. Mark the locations to be drilled with the sharp end of a Phillip head screw driver.

This action will pilot projfct electric drill with its drill bit cybe the locations to be drilled during the drilling le. Mark the location to be drilled using a Phillip head screw driver. Drill the cueb locations slowly without pushing the electric drill to hard because this indiscreet action may break the acrylic sheet.

Once all holes have been drilled, the mold is considered done as shown by the Figure projdct below. Bend up LEDs cathode leds 90 degree up. The LEDs with their cathode legs bent are ready to be put into the holes of mold for soldering. Solder the cathode and cathode contact points. The connection of cathodes of LEDs inserted into the 1st row holes of the mold. The connection of cathodes of LEDs inserted into the 1st column holes of the mold. Repeat the step 5 for 7 times for prokect remaining columns.

The resulted LEDs cathodes connection is shown as below. The resulted LEDs cathodes connection. Although all cathodes of LEDs in this LED layer are connected, the whole thing still looks very flimsy or lack of solidity. So, two braces steel wires will be added to support the LED layer. The space where the braces will be added to support the LEDs layer. Cut out 2 steel wire with length of 18cm. Clean the stains and thin oxide layer of of these wire using sand paper.

Hence, there will be an extra 0. Hence, the steel wire should be clean with sand proect first. Then, straighten the cleaned steel wire by gripping firmly its each end with a pliers and then pull hard with force. Surprisingly, the steel wire becomes straight as shown below. The state of steel wires before an after straightened by using a pair of pliers.

The cut wires are ready to be used as braces. Start solder 2 contact points between the brace ends and cathodes leg of 8th LEDs row. Then, solder the remaining 6 contact points. Process of inserting a brace to LEDs layer. Repeat the step 10 to insert another brace to the space between the 4th and 5th LEDs rows.

The resulted LEDs layer with braces is shown below. LEDs layer with braces. The LEDs layer is considered done here. Somehow, it must be tested before it be taken from the mold. One end of a crocodile clip cable is clipped to the sticking out cathode leg at the top right corner of the LEDs layer while the other end is clipped to one end of a resistor 0hm.

Change your multimeter into the continuity checking mode. Touch the negative probe to another end of the resistor ohm and tap the positive probe to each anode leg of LEDs of the LEDs layer. The LED with its anode tapped by positive probe will light up if the connection correct and the condition of that LED is good. Testing the LEDs layer. The appearance of the LEDs layer taken out from the mold. Repeat steps above to solder other 7 LEDs layer.

Then, insert the 1st LEDs layer into the mold as orientation shown below. The sticking out cathode leg is at the top right corner. The orientation of the LEDs layer on the mold. Try to place 2nd LEDs layer in the same orientation on the top of the 1st LEDs layer with the help of triangle supports made from card as shown below.

The triangle supports are made to provide lef distance about 2. Start the soldering along the sides of the LEDs layer. Try to move around the triangle supports during the soldering process to ensure 2. Checking connection of anodes of LEDs between layers.

The structure of complete stacked LEDs layers is shown below. It has the shape of a cube. The LED Cube is considered done here. The structure of complete stacked LEDs layers.

Then, remove the LED cube from the mold. Now, the mold will be modified into a base for placing resulted LED Cube and microcontroller circuit board to be build. Modify the mold into a base for placing LED Cube and microcontroller circuit to be build. The current appearance of the acrylic sheet is shown below. In this stage, these holes will be used to mount the LED Cube later.

The current appearance of the acrylic sheet. Draw a 1cm x 1cm square box at each corner of the acrylic sheet as below. The interception point between lines connect pair of opposite corners will be drilled for hole installed PCB stands to stack up the base. Draw a straight vertical line 1cm to the left of the 8th grid line.

Then, add in short horizontal lines at a distance 1cm after each horizontal grid line except for 8th horizontal grid line. Also, add in another short horizontal line 1cm after the short horizontal line which situated at a distance 1cm from the 7th horizontal grid line. The interception points formed between these short horizontal lines and the straight vertical line 1cm to the left of 8th grid line will be drilled for holes to pass through the cathode risers formed by steel wire connected to cathode of specific LEDs layer.

8x8z8 Create points to be drilled for holes to for cathode risers to pass through. Drill the marked points in step 2 and step 3 using drill bit 3mm. The resulted acrylic sheet is shown below.

Drill marked points for holes. Next, it is a need to drill holes for fitting in the microcontroller circuit still have not created in this part. The donut board used has the dimension of 10cm in width and 22 cm in length as shown below. The dimension of donut board used to create the microcontroller circuit board. Please align the donut board with one of its length side parallel to the left width side of the acrylic sheet as indicated. Try to centralize the position of the donut board and it seems there is an extra 0.

The positions of pre-drilled holes at the corners of the donut board are also do not fit the dimension. Align the donut board with one of its length side parallel to the left width side of the acrylic sheet as indicated.
