Fungus, how is building something that someone else designed and built dumb luck. I have repeated the test 3 time, and had the exact same results, its not dumb luck that these cubes havnt failed.
Did you use a different source of components each time...? I've got datasheets for LEDs that say they can take 200mA pulses, I've got datasheets for LEDs that say they can only take 35mA pulses. Dumb luck is dumb luck until you try it with the 35mA LEDs.

...that is your business
The only problem is that your taking your business and telling noobs that that's the way to do it. You're not paying for their components, don't give them advice that might destroy them.
