8X8 LED Cube Take 2

About: AA drgree in Electronic Engineering

this is my version of the 8X8 led cube.  utilizing stacked Arduino boards for a low profile inside the box . all of the controls and status lights will be relocated to the outside of the enclosure on the sloped front panel. a PC Board will be designed to solder underneath the display case base. each row plus the ground will be connected by jumper cables. as will all of the status lights and controls one the front panel.  everything connected to the stacked Arduino boards. the USB programing port, power switch, and power cord connections will be in the rear. 

I had mirrored the case and back panel of the cube for more of a lighting effect. Everything else has been completed except for the PC boards and the power supply. I will post updates when finished.

    Glad to see you're still at it.
    I am on my second revision of the base board, and not sure how many revisions in total of the controller.
    The one I last showed you was an all SMT controller - but people shied away from that in preference of through-hole construction.
    My latest controller is a hybrid, allowing for 80% or so of the components to be either SMT or through hole at your discretion, and take either the Arduino type ATmega328P or the ATmega32A microcontroller. Here are my current boards. Yes, they are for sale if you want one too! LOL! As before, all the components are on a single board.

    This board sold out completely - someone in Russia bought all my stock.

    These will be superseded by the upcoming ARMS boards which will have connectors for wired audio trigger input, a Mic module, and a wireless remote module. The board is still about the same size.

    It runs perfectly on those cheap iPod charger plugs, so I use those or 3 "Triple A" (AAA) penlite batteries if I feel like moving it away from the computer.
    Otherwise I power it off my USB port.


    Sorry, DOUBLE A (AA) batteries.
    The smallest I have run it on, just to prove it could be done was 2 triple A.
    But of course that doesn't last long.
    On 3 double A (AA) penlite batteries, you can run it for hours and hours.

    Working on a new project for my PIC class its a DC volt meter using an 8051 micro controller. here are some pics. Still have some software issues to correct.
