Light up your hair with these beautiful iridescent glowing hair flowers. The magical light comes from Adafruit n00ds: a fun, flexible noodle-like LED filament. These little noodles are jam-packed with LEDs and look a bit like EL wire, but with no need for an inverter. They are available in a variety of colors and lengths so you'll be able to find just the right n00d for your project.

This is a fun beginner project that requires a little bit of tricky soldering but no coding or software. Just connect the n00ds to a coin cell battery breakout and they will light up and glow.

Materials

Adafruit n00ds come in a variety of colors and lengths. They come in single-ended or double-ended variety. The double-ended variety are a bit easier to solder to: solder a wire to each end. The single-ended variety have both leads on one end, which is perfect for some projects where you don't want to have to double back to the battery, but these are wicked hard to solder to.

For these hair flowers I found the 300mm single-ended n00ds in red, pink, and warm white.

Parts

Each 300mm n00d requires 3v of power. These coin cell breakouts used with lithium coin cell batteries provide 3v and come with a handy on/off switch. This is a wonderfully compact way to power your lights -- the whole thing is self-contained with no extra battery boxes or wires to manage.

Connect the n00d to the coin cell breakout with silicone stranded wire. Don't skimp and use cheap wire! For wearable projects the wire tends to get flexed a lot, and this wire is a lot less likely to break.

The best way I found was to use crimping beads for jewelry to help solder onto the ends. Similar electrical crimped connections with solder will likely work similarly.

You'll also need soldering supplies: a good soldering iron, solder, and heat shrink tubing.
