Could the first led be damaged and causing this odd behavior.
(I can't just cut the strip since it the waterproof version.
Yes.But equally you could have blown he whole strip, it depends what your power supply did when you fried it.
Yes you can, it is quite soft and cuts with a scalpel. You can seal it up with silicon adhesive.
i dont think so, some of the LED's still light up when they've got power.
i dont think so, some of the LED's still light up when they've got power. expect they're always green and uncontrollable..
That means absolutely nothing. I have a totally FUCT ( Further Use Completely Terminated ) neopixel matrix and some LEDs light or flicker when power is applied to it. I know it is FUCTed because I accidentally attached a 12V power supply to it instead of a 5V one. When a part is dead it is not always unresponsive, it sometimes partially works but not enough to be useful.
And... you're about to blow up the Nano as well.There is a "500mA absolute max" diode between the USB supply and 5volt pin.Powering more than eight (8*60mA) addressable LEDs from that 5volt pin will send that diode to silicon heaven.What voltage did you use on the input of that linear 5volt supply.144 LEDs could use 8.5Amp. That's 8.5watt for every volt above 5volt.= ~60watt with a 12volt input and an all white strip.A 2N3055 without heatsink might be able to dissipate ~3watt.Use a 5volt/10Amp switching supply for 144 LEDs.Leo..
19.4V and 3.65A, is 70W. so that should be enough. since 144*0,060*5= is only 43.2 Watt.
You can't say that, you need the voltage and current in values that your component needs them. You can only talk in power terms if you are producing the current and voltage you need using a switching regulator and I don't think you are.Your regulator uses a 2n3055 transistor as a linear regulator so the current drawn from the power supply is going to be the same irrespective of the voltage you regulate it to. So 1A at 5V regulated by a linear regulator is going to be 1A at 19V from your power supply. So it takes 19W from your power supply to provide 5W of useful power in your load. The difference in power 19 - 5 = 14V @ 1A = 14W is burned off by the regulating transistor. Which is why it gets hot, and it could be that an infinite heat sink is not sufficient to burn off this power. It is all to do with the thermal resistance between chip and case and case and ambient. You have no control over the chip to case thermal resistance, you find that in the data sheet.For more information see:- http://www.thebox.myzen.co.uk/Tutorial/Power.html and the examples page found off that.
