8 x 8 x 8 LED Cube


And it's available as a kit from Jameco, a company I've bought many, many things from.


  1. The next step is to change out the White LEDs for Red-Green-Blue LEDs. Then you can have some great looking star bursts. But at fifty cents each or another $256.00 maybe not.

    1. Unless they're two-lead LED's, it would mean a bunch of added wiring, too.

      I downloaded the instructions from Jameco, and the only "hard" (more tedious than actually hard to do) part is assembling all 512 LED's into the cube.

      You make an 8 x 8 grid in a piece of wood, or use a piece of pegboard, and assemble the first 8 x 8 grid of LED's after you bend the leads on them a certain way.

      Then you make 7 more 8 x 8 LED arrays, and stack them.

      The next time I'm at my local electronics place I might get the LED's. I pretty much have all the other parts "in stock" here, and I have several of the correct Arduino boards from another project I built for somebody.

  2. That's pretty cool right there.

  3. Very cool. Beats the heck out of those sound-activated Christmas tree bulb thingys we had back in the '70s. :)

    1. The only thing that come close is an "Infinity Cube", which is a bunch of the "pin lights" used on Christmas trees inside a box made of semi-reflective plastic.

      My roommate in College had one, and "under the right conditions", you could watch it for hours!

      It was like this thing, but instead of the votive candles, it used the lights, and they were motorized so the turned inside the plastic cube.


  4. Tempting... If I could find a kid to build it for me ;-) When I was teen with an electronics habit, I would have jumped at the idea of building something like that.


Keep it civil, please....

Update On The Pioneer SX-780 and Speakers

 Sooooo....I dragged the two speakers I made some time ago out of the basement, and set them up with the SX-780. When I used these speakers ...
