I searched the internet for a tutorial and found a post on instructable. Coincidentally, the author of the article is the same person who made the youtube video.

This gave me the inspiration to make my own. There is a problem, though, that this tutorial requires too many components and some of which are difficult to find.

I told myself, "There must be an easier way!

As a result, I came up with my own design using only a few common components. 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.

Quickly setting up which of those LEDs on that layer should be on and then repeating that for the other layers, gives the illusion that we can individually control every individual LED. More soldering, having to deal with alignment of the extra wires. Larger cube also meant more fragile cube. The result is an impressive 11"x11"x11" cube. However, it took many more hours to build compared to the usual led cube.

This resulted a lot of unnecessary circuit, which I was later able to eliminate. Various versions of the code is on github. View all 14 components. All the top LEDs are rested in the holes of the wooden jig. It was standing like this while I solder all the cross wires.

Foam core board is my friend. A very simple jig made of foam core with slits cut using a razor blade.

Holds the wires at perfect 4cm spacing. This small screwdriver was just the right weight to lightly hold down on the wire that I'm soldering. I like how the cube looks when you're looking down the "aisles" rather than straight on the walls. So I decided to make this the front of the cube.

The cube will be mounted on a PCB instead of a piece of wood. Originally, I planned on putting all the components on this one board.We made this project in just 5 days onlyjust three days to finish the hardware making and the assemble, then two days to prepare the code. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

It is commonly used for showing a state of the electronics. A Light emitting diode LED is essentially a p-n junction diode. When carriers are injected across a forward-biased junction, it emits incoherent light.

Most of the commercial LEDs are realized using a highly doped n and a p Junction. By flashing each layer of the cube one after another really fast, it gives the illusion of a 3D image, this is also called multiplexing.

This is a total of LEDs. Actually this is what we gonna see in the programming part because it will be a little bit deceptive there. The display itself is multiplexed so instead of requiring connections it requires one to each of the five layers and 25 to each LED in a layer making a total of The cube is refreshed by a software interrupt routine with each layer active for 2ms, so the entire cube is refreshed every 10mS Hz.

This results in a display with no visible flicker.

After finishing the design, go to fabrication output and set some parameters, for me I prefer the black color for my PCB. Do the payment and wait for the delivery. Just 5 days only to receive the packet and it was an amazing service, the PCBs are very well manufactured as usual and all the labels are there with the description etc, so the making of this project will be so handy now. Before starting the soldering of our components we need to prepare the CUBE shape first, and to do this I advise you to follow this technique!

Take a peace of Polystyrene and draw a five fives matrix then drill a small hole in each lines intersection now take 25 LEDs and bend all them Cathodes and put one LED in each hole to solder all the Cathodes together in order to make one layer, then repeat the same thing to make 5 layers and solder them together to create this CUBE shape where you have all the Anodes of the same line connected together. Don't forget that we are making 5 lavels so we should have 5 pins for cathodes in the whole cube.

And about the CUBE, we will solder only the Anodes that we have in the lowest layer and we will use five jumper wires to connect the Cathodes of each layer to the appropriate placement in the PCB. Note: You need to keep your soldering iron nice and clean. That means wiping it on the sponge every time you use it. The tip of your soldering iron should be clean and shiny. Whenever the you see the tip becoming dirty with flux or oxidizing, that means loosing it's shinyness, you should clean it.Add the following snippet to your HTML:.

So I was intrigued and then hooked when I found Kevin Darrah 's great site with his detailed explanations and build video's. Further searching revealed further cube designs from which I have taken other areas of inspiration.

I leveraged his cube design rather than Kevin's. SuperTech-IT has focused on simplifying the hardware side with a single PCB approach integrating and expanding both Kevin and Nick's programming approach with a focus on eliminating all wiring. So a plan was set. Using Kevin's schematic, Nick's Cube structure, design a single PCB and develop a solution to both simplify the build and strengthen the cube itself.

Whilst cheap I was a little concerned about quality. Once you get into the hang of pushing an LED into the breadboard, pressing the button, watching the LED flash through the colours it doesn't take too long to review all As an aside I didn't find a single defect and was very pleased with the quality of LED's. While the breadboard is out it's a good time to test and validate the LED current limiting resistors you'll need to use. There are many calculators out there to help you choose the right value and it won't be the same for all the colours Red will almost certainly have a different requirement from Green and Blue.

You can balance the value of the resistors to produce a clean White colour within the current limits of the LED. Building a cube of this complexity is not to be taken on lightly.

This will require a significant investment of your time.

The approach I designed simplified the soldering of each 8x8 vertical "slice" of the cube in a single event, as opposed to building lines of 8 LEDs in turn and then soldering 8 of these together in a separate operation.

You will require a jig for this approach and a little time invested here reaps huge benefits later. Take your time in building this jig. The more accurate you are here the more accurate your final cube will be. One of the concerns I had on previous examples I have read about was the use of simple butt joints when soldering the LED's to the framing wire.

This would lead to two key issues. So I designed a solution whereby each LED is prepared with a loop at the end of each lead, through which the framing wire passes which both holds the wires in position during soldering and also provides a mechanical connection in addition to the solder for increased strength.

The downside of this was that preparation of each of the LEDs took longer - I did this in batches of 64, a slice at a time, and got this down to around 3hrs per slice. On the plus side the actual soldering of the slice using the previous jig took just over an hour. Now you need a tool - a good project is always one where you need to buy a special tool These have a straight parallel long nose and flat end - see picture.

Now comes the long task of preparing each of LED's. I suggest you do them in batches. More details in the pictures above.It means commanding LEDs using one Arduino board.

One of the main considerations when first designing our cube was deciding how large to make it. The structure of the cube is as follows: All the LEDs are connected in parallel.

AC100200 - LED Light Cube

The anodes of each LED form the horizontal meshes of the grid. The cathodes are held vertical. The co-ordinates of each LED are defined using the 25 cathode pins and 5 anode pins. Anodes are made on and off to determine the layer of LEDs, and the 25 cathode pins, coming out from the bottom, is used to refer which LED of each layer is to be illuminated.

Each of the LED layers is arranged in a 5 x 5 matrix and controlled by a transistor in an emitter follower configuration connected to the LED anodes. The transistors used are 2SD NPN transistors, if an alternative is used it should be of similar specification, have an IC rating of at least 1 amp and check the pin out. I have configured the variable resistor such that it can control the speed of the sequence of designs.

The 2 push buttons are capable of bypassing the sequence to a pre-defined design and continuing the loop thereafter. Since we need 30 outputs from the PIC to designate the co-ordinates of the cube plus two inputs for the push buttons and one for the speed regulator, we choose a forty-pin PIC, 16FA, for our design. The next issue we encountered was to amplify each signal received from the PIC.

Using thirty transistors for this purpose would have made the circuit look more complicated. Microcontroller is type of microprocessor furnished in single integrated circuit and needing minimum of support chips. Its principal nature is self-sufficiency and low cost. PIC is a family of microcontrollers made by Microchip Technology. This is one of the newest groups of devices from Microchip.

There was a lot of circuitry that had to be constructed in order to realize this project. This circuit had to take inputs from a limited number of microcontroller pins and connect them into something that could control the cube.

I had simply taken the input of each column and each ground level directly from a microcontroller pin this would have taken 30 pins of the PIC 16FA microcontroller. This would have been alright for my final application which only needed three extra pins for the switches and controller but would make it hard for future projects to utilize my design. I created a driving circuit Figure 1 that could control 25 columns and 5 rows of pins.

High voltage, high-current Darlington arrays are ideally suited for interfacing between low-level logic circuitry and multiple peripheral power loads. Typical power loads totaling over W mA x 8, 95 V can be controlled at an appropriate duty cycle depending on ambient temperature and number of drivers turned on simultaneously.

These devices will handle numerous interface needs particularly those beyond the capabilities of standard logic buffers. The figures shown below explain the way of driving current to the LEDs on the cube.

The control software for the LED cube has a very simple structure. First we initialized two arrays with pre-rendered columns and rows for all possible digits and letters so that we could look these up easily for string display on the cube.

In our case we could have just hard coded the string since we have only one intro string, but we decided to do this and use an initialization routine so that this could perhaps be utilized in future projects that attempt an LED cube and want to display text. It also saved some memory space. We made an initialization routine that we call at the very beginning of the main function to set up the directionality of the ports that we used to control the cube.

The actual layouts of pins are described in detail in the comments of the code in the initialization routine.
