Description LED Cube
Attention geeks! This cube made of colorful LEDs not only provides an impressive light show, but it is also electronically interestingly implemented!
Great light show:
The 64 LEDs arranged in cube form can take on over 1000 different color shades. They light up in predefined patterns with various effects: Sometimes the LEDs blink one after the other, then again complete patterns move back and forth, rotate and change color.
The various settings change very quickly, often several times per second - yet no pattern is repeated for over half an hour in the fixed programmed sequence!
The LED cube is of course an impressive sight, especially in a dark room. The great effects are nice to look at on many occasions: At parties, they provide the right light show, at work for a few relaxing moments!
Geeky look:
Even when turned off, the LED cube is a beautiful sight for many geeks: Above a shiny black base, the LEDs are arranged in a cube shape (4x4x4) on a mesh of wire. The wires are not insulated or otherwise hidden, all solder joints are visible and the switching elements on the base are also not covered. The delicate structure is only enclosed by a removable plexiglass cover, which is of course transparent.
This puristic design makes the LED cube look similar to a self-built one. However, you don't have to spend nights at the soldering iron to make it light up - a push of a button is enough.
Exciting electronics:
If you enjoy tinkering a bit, the LED cube definitely has potential. In the detailed view of the switching elements, connection options can be seen. Although we haven't tried it, with a bit of reverse engineering you might even be able to reprogram the cube yourself!
But even without violating the warranty conditions ;) the LED cube is interesting in this respect, as it is particularly elegantly implemented and programmed. Each LED has 4 connections (three for the colors and one for the ground); however, several LEDs always share a line, so not every LED can be controlled individually - the others in the same row or column are always influenced as well. Therefore, it is particularly impressive how many patterns are still possible (over half an hour in rapid succession) and a nice puzzle to consider which pattern is implemented with which switching setting.
Do you also want to know how the many colors are created? Each LED contains three diodes in the colors red, green, and blue (RGB). Each diode can be supplied with voltage via a single line. The different colors are created by turning on several diodes, which are in turn supplied with different voltages. For example, for turquoise, certain voltage values are applied to the blue and green diodes while the red diode is turned off.
As you can see, the LED cube is not only colorful and pretty to look at, but it is also perfect for learning a lot about electronics or teaching others. In any case, we hope that you have gained a few new insights from this description - shopping can indeed be educational ;)
