the light intensity punch and when used in a 3D LED cube must be viewed in a dark To build an accurate 3D LED Cube Matrix with evenly spaced and aligned . 8x8x8 Arduino LED Cube: This is a fairly simple project, but it is time First. you must solder a wire to the center top of the cube. This is 8x8x8 LED billpercompzulbe.ga This senior design project documentation will outline in detail the process for the completion of Group #15's project - a 3D LED cube. This paper will describe the.

billpercompzulbe.ga can think it as of low resolution displays. In normal displays it is normal to stack pixels closer to each other in order for better resolution but LED cube. Build your 3D led cube and created unlimited 3D effects. Required led current for full brightness: 5mA (this can be found in the datasheet of. This Instructable is the most comprehensive step-by-step guide to build an 8x8x8 Led Cube ever published on the intertubes. It will teach you.
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. Figure 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. Figure 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. Figure The orientation of the LEDs layer on the mold 3.
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 separation 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. Figure Checking connection of anodes of LEDs between layers 8. The structure of complete stacked LEDs layers is shown below. It has the shape of a cube.
The LED Cube is considered done here. 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. The current appearance of the acrylic sheet is shown below.
In this stage, these holes will be used to mount the LED Cube later. Figure The current appearance of the acrylic sheet 2. 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.
Figure Create points to be drilled for holes to for cathode risers to pass through 4.
Drill the marked points in step 2 and step 3 using drill bit 3mm. The resulted acrylic sheet is shown below. Start soldering layer by layer and use any object like a ruler or even a piece of Sunboard of width roughly 2. Finished structure after stacking all the eight layers, will look something like this. The 64 Anode poles must protrude out of the Sunboard at the bottom in order solder wires for connection.
After soldering all the 8 layers with the Anode Poles, solder wires to the Anode poles. Next, we will continue to design the main circuit board for housing all the ICs, transistors and the Arduino Nano board. This piece also acts as a base for the LED Cube.
Insert the PCBs into the housing and connect the power supply through a switch. The structure is very strong and all the electronics including the power supply are concealed inside the base. In fact, you might have most of the components for this project if you bought an Arduino Starter Kit or some similar kits. Of course, this design is not the safest, nor production quality, but it's intended to be that way.
This project, after all, is a DIY toy I made to fulfill my crave of making things. You can buy an LED Cube kit on eBay for about times cheaper than what it costs to make it this way. The only thing you'll learn from those kits, however, is how to solder and that's it. The PCB has all the traces required. The micro-controller is pre-programmed and you don't even need to know anything about electronics to put it together.
With that being said, this project is not easy. You'll run into problems and Google will be your best friend.
