I have 8m of neopixel strips (30 leds/m), bought as two reels. If I solder them together to one, will the data provided at one end still reach the other end?
I am asking because on the uberguide it says that the VCC drops of (due to resistance). Will the same be true for the data?
Will the data signal be strong enough for 8 m of NeoPixels?

Re: Will the data signal be strong enough for 8 m of NeoPixe
The signal will not drop off because each pixel is a 'repeater' and re-transmits the signal to the next pixel in the strip.
But voltage drop over the length of the strip can be a real problem for long strips. With 240 pixels, I'd recommend at minimum a power feed to each end of your 8m strip.

Thanks for the answer! I have added 4 power feeds, separated at a distance of 2 m each. That should suffice, right?adafruit_support_bill wrote:The signal will not drop off because each pixel is a 'repeater' and re-transmits the signal to the next pixel in the strip.

That statement would be very handy for the neopixel uber guide power page.adafruit_support_bill wrote:The signal will not drop off because each pixel is a 'repeater' and re-transmits the signal to the next pixel in the strip.

Yes. A feed every 2 meters would be excellent.
