Her instructions are great, so just follow them! The only confusing part was how she connected the fiber-optic bundles to the LED strip. In a nutshell, she is trying to position each Fiber Optic bundle above a LED on top of the waterproof cover. Since the waterproof cover is made of Silicone, hot glue doesn’t bond. So she lays down a HEAVY line of hot glue between each bundle, and then uses tape between the bundles to strap them onto the LED strip in position. This works, and relies very heavily on the STRENGTH of the hot glue, which is fine for a costume, but not great if you want to really move around.
For mine, I followed the same instructions mostly, except I just wanted something more durable so we could go dancing and not worry about it falling apart.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
