hi, it has been a long time since i don´t upload anything in this forum,
this 4x4x4 rgb led cube took 2 years to get it working and for soldering the 64 rgb leds took 2 whole days of non-stop soldering and the remaining time to find a power supply to power it up.
i put a mic on the cube so that it reacts with sound, like a vu-meter,
i would recommend to power the mic circuit with a another 5v supply independent from the cube (for example my atx power supply has 3 independent 5v supplies) to reduce the noise.
anyway here is my code and a video.

That's really nice. Yeah it's always surprising how many amps those LEDs can draw, maybe if you lowered the brightness you could get it to work with a smaller power supply.

Looks like a lot of work, must be pretty satisfying to have it working after all that time!

oh yes, when i first power it up it felt soooo good to see it turn on, all that soldering finally paid off.
i have been watching for days when i did the first test
