I made a petticoat or under-slip that can be worn underneath a variety of long skirts or dresses.  It would be simple to convert this project to pants, chaps, a vest, or any layered costume look.

The 3d printed "belt buckle" houses the Circuit Playground and adds another 10 reactive lights and button controls to the ensemble.   It can work as a standalone light buckle without the skirt as well.

I wanted to cover my whole skirt with just a few pixels, so I took some extra time and wired the pixels up individually. This way I could leave 10-12 inches between pixels and get a more spread-out and random twinkle effect.

If you don't like soldering much, you can also use our pre-soldered LED dot strands. They come in 2" or 4" spacing, so your pixel density will be a bit higher, but they're much easier to build and can be more reliable than hand-soldered pixels.

This guide uses 3 colors of silicone stranded wire to connect the pixels. You can instead use our silicone stranded ribbon cable. It's a little tricker to keep track of your wires since they're all black, but you end up with a more streamlined project with fewer wires to pull and catch on.

For a lighter weight power source that lasts a little longer, you can use a Lithium polymer battery. These are great for adult use but can catch fire if they're damaged or if they get wet, so if you're making this for a kid, stick with the AAA battery pack.
