Im toying with different ideas for ironman lights (chest and hands) and as wiring up individual leds and resistors is a bit of a pain in the butt, i have bought a 12v flexible led strip. Thing is its sealed and its not intended to be cut to various lengths, but thats what i intend to do (obviously i would have to solder wires to it)
Now from looking at it I can tell you it has 48 leds, and what appear to be 16 resistors. The copper strip its all attached to is divided by black lines. Im assuming that as an led is about 3-4v that it is set up in 16 lots of 3 leds and a resistor, so if i were to cut it it would have to be in groups like that.
I ahve included a pic and have outlined the wires at the start of the strip, the resistors wch have "181" on them and in green ive draen on the lines.
The main thing that is confusing me (maybe coz my electronics knowledge is limited...) is if the strip goes RESISTOR-LED-LED-LED etc etc Then why are the wires not attached at the very beginnng? and why is the very beginning not a resistor? you can see from the pic it starts LED-LED-RESISTOR-LED-POS WIRE-NEG WIRE-LED-LED-RESISTOR-LED-LED-LED-RESISTOR etc etc
so hopefully some electrnics whizz can shed some light on this for me
