1 melted led later and it works
found the dot it was where i thought it should be under the "V" in the lettering easier to solder then i thought, some paste solder and plenty of flux it's a beutiful thing
the diode network is a pain to solder but i can do it if i can figure out how it is oriented i cannot see a mark for orientation does the lettering orientat it ie. dose the "V" mark the first pin (and the dot) like most dip packages (pin 1 is lower left when reading the lettering) that has got to be the smallest part i have ever concidered soldering i started electronics at the end of tubes and the begining of ICs
as long as you can wire the strands together and power the neopixels (they can use an astonishing amount of power i would limit to about 100 neopixels and use about 20 per cloud you can use an arduino uno also do not power long strands from the 5V pin on the arduino you can easily overload the voltage regulator use a separate tap from your power supply
Nice start (learning is what arduino is all about) i see some things i will do differently when i make one after i finish my neopixel ring flash for my camera
Use a 3 c or d-cell holder with cheep batteries it should go many times longer and still be portable
good instructable i use a double edge razor myself and found a couple 40 plus year old adjustable razors a good cleaning and they are good as new. blades are important don't skimp on them, bad blades will cut you and give a bad shave
