Really enjoy your projects, Kevin. Thanks for sharing!

@WiZeR911 11 жыл бұрын

You are an absolute legend. Thanks so much for all the work you have put into this. The level of detail in the code is fantastic and has helped me a lot to understand this. I'm relatively new to electronics and I wanted to jump into a worthwhile project quickly and your videos and code have helped bundles. I think I'm going to do a quick 4x4x4 single colour first and then move on to this monster. Look forward to more of your content.

Very clever man. I love it. Logic manipulation is awesome especially when you're pushing it as far as it can go. I wonder what the average cpu load is while your effects are looping. I suspect you're not even taxing the cpu.

Yeah i'm having a blast, there are so many possible ways to animate it. (or let it animate itself) One really fun thing to do is to write a code that animates sort functions. Bubble or cocktail sorts make for really interesting patterns, especially if you make the coordinates and values of the numbers to be sorted random. I'm using height as value to be sorted.

Thanks for the code Kevin I saw that 1 red led is broken on your cube in the video on 5:00 when you go from red to blue on the side where you sit. I've been practising with EAGLE, i have got 1 shift reg with all the resistors and transistors on 1 sided pcb ready so i only have to copy it 8 times on 1 pcb layout so that i have 1 print for 1 color and order that 3 times, gona start tomorrow with the anode pcb

@JurriaanPetersen 11 жыл бұрын

Also the BAM counter and BAM bit section of your code can be done quicker like so: BAM_bit = int(BAM_counter/8); This would make your ISR smaller. I hope you don't take my comments the wrong way, I'm a big fan!

@VincentTerra 11 жыл бұрын

Kevin I was thinking. Couldn't we implement PWM as easy as BAM ? Say we have a counter which is incremented with each interrupt. Now say we use an array to store the brightness value for each led. Basically in the interrupt we could just compare the values to the counter and say, if the value is larger than the counter set the corresponding led to high or low otherwise. The only disadvantage I see is the slightly lower refresh rate because of the necessary if statements in the interrupt .

@VincentTerra 10 жыл бұрын

Kevin since the state of the leds dont change per bit. Couldn't you scrap the BAM-Bit variable and just set the output once at the BAM-Counter switch statement. It would beuch more efficient.

@JaakkoF 6 жыл бұрын

Nicely done and good that you got it to work, but the code is something horrible to read due to your syntax, it is so much out from the normal C/C++ style.

@JurriaanPetersen 11 жыл бұрын

Not a professional cube builder myself but I have to say that you made things really hard for yourself. For starters the arrays wich hold the data can be done much easier with multidimensional arrays like this: Leds[row][leve][bam][colour]; The sizes would be: row = 8, level = 8, bam = 4, colour = 3; This way you have all the cube data in one big array but it is easy to manipulate because of the multiple dimensions. To find a LED you would do Leds[currentLED%8][currentLED/8][BAM][Colour];

@Kevindarrah 11 жыл бұрын

if you're only using single color LEDs, then yes, you will have to make modifications. You don't have as many cathodes, so you don't need to shift out as much data, and you could delete out a lot of the stuff, but it could be done easily if you understand what's happening here

Well it works and you can only go better and more efficient from here. Maybe if you get the code a little more efficient, you can make more processing power demanding animations.

I really like the cube but i think that it would be a little bi t to "big" for me. Since you want to sell those with kickstarter (want you?) i really would appreciate a smaller version like 4x4x4 or 5x5x5. I think the code would be pretty much the same but i would be easier to build and also cheaper, though 8x8x8 looks so amazing :)
