releases acetic acid when curing, which can destroy electronics. It’s fine on the
outside
of the strip, but not
the
inside.
Use GE Silicone II for sealing strip ends, or good ol’ hot melt glue.
2-sided carpet tape provides a light grip on the silicone sleeve; something like a Post-It Note. Or you can try
clear duct tape over the top.
All LED strips are manufactured in 1/2 meter segments that are then joined into a longer strip. The pixel spacing
across these joins is usually 2-3 millimeters different than the rest. This is not a manufacturing mistake, just
physical reality.
Some batches of 144 pixel strip don’t have pads
between the LEDs. If you cut these into shorter sections,
the only way to connect to them (except at the half-
meter segments) is to carefully solder directly to the
LED. The corner with the notch is the GND pin.
NeoPixel strips are just the start…we’ve got
shapes
too! Rings, grids, shields and more…
