  • damn thats killing my brain xD

  • i understand until 7:00 so if you light up the highest one why doesn't the lowest one light up?

  • @arnokleine623 its all about a complete circuit. Just look at the grid, and see if current can pass through all the way from positive to negative. It'll make sense to you. kinda trippy stuff

  • my heads is gonna blow if i make this mannually xD

  • good work

    

  • nvm saw your other video and now i get the 8x8

  • 8x8?.... its 4x4x4

  • lol how epic is this,

  • I saw the three videos u made. There is jsut one thing i dont get. You devide your 8x8 grid into 4X4 grids. So far so good. I get how it works if you would just palce them side by side 2 dimentionally. But.... How do you stack the 4x4 grids without gettign a connection you didnt want to have. If you stack them you somehow ahve to solder them together without makeing wrong connections like perhaps connecting the anodes of the first 2 layers. How does it work?

  • would you happen to have the schematic itself? The verbal description of splitting up the 16 wires into 12 is still throwing me. I understand what you're doing, I just need to actually see it.

    I like the project, though. I'm working on one of my own. Well done!

  • This was the first video i saw but when i noiced your other videos about Arduino an Co. i subbed!!! :)
