If you have plenty of spare time, steady hands and lots of LEDs it's always fun to make your own LED cube, and a neat example of this has been demonstrated by Instructables member laurenk. This version relies on some intense LED multiplexing, and the instructions are quite helpful both explaining how to use a jig to keep the LEDs straight and the use of an enclosure to mount the cube and hide the rest of the electronics. A quick demonstration is shown in the following video:
Furthermore the sketch uses a series of binary numbers to address each LED, and with some though many types of effects can be created. So to get started, check out the project Instructable page. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
If you're interested in making not only an LED cube - but an RGB LED cube - check out our CUBE4: RGB LED cube kit:
It's easy to construct and use, and with an onboard Arduino-compatible board the cube can be used to display all sorts of data or create visual effects. It's easily controlled via simple text commands via the USB port - or write your own Arduino sketch. It's incredibly customisable and there's so much more.
