Sure, you could get a regular light fixture like a normal person… Or you could use close to a thousand RGB LEDs to light your room!
That’s what [Dmitry] decided to do after trying to figure out the best way to light his pad. You see, his room is 4 by 4 meters, and WS2812 RGB LED strips happen to come in 4 meter lengths… Coincidence? We think not.
The problem with using 16 meters of LED strips is powering them… You see, at 16 meters, you’re looking at about 5V @ 57.6A — and we’re guessing you probably don’t have a 5V 60A power supply handy. Not to mention if you run them in series, the resistance of the system is going to kill your efficiency and the last LEDs probably won’t even work… So [Dmitry] had to break the system up. He has two power supplies feeding the strips from the middle of each pair — that way, he doesn’t have to worry about any voltage drops due to the length of the strips.
Controlling them was the next fun part. Using an ATMega, and a Nordic FOB (discontinued but useful RF remote) he’s able to control the lights to do whatever he wants — and he’s shared the source on his website as well.
