The ws2801 strip has problems, when I use less than 10 LEDs it is getting over powered!
How it can power the entire strip I have no clue. 20x120mA = 2400mA (3 times the capacity of the supply) yet it works perfectly.
No it isn't, it works perfectly.
The type I use is the 12v 36mm square.
One of the mistakes I made was thinking I needed to supply less amps for less leds but that doesn't make sense at all. A shorter strand just draws lesser amps right?
