As the Christmas holiday approaches while our bus is parked in Tucson, I found myself inspired to create an Arizona inspired e-textile project that can function as this year's Christmas hat.
I started with a straw hat that I had purchased to walk around the desert with; the decorative holes were begging for sewable LED's.
I also experimented with where I might want to place a micro-bit and battery pack
so it would be comfortable and secure inside the hat. The microbit would be used to control the lights using code.
and play with controlling them with block code (via MakeCode). This was actually the first time I have used neopixels in a project. I always felt intrigued but intimidated by them.
Thanks to the Adafruit Uberguide to Neopixels, I started to understand them better.
It still baffles me how so much data can pass through a single piece of conductive thread through a series of neo-pixel lights.
wiring the circuit, the code and neopixels.
to sew 7 neo pixels onto a piece of black ribbon.
No matter how hard I looked I couldn't spot the problem.
circuits after each cut.
I reworked my design to one with the 5 working neo-pixel strip and moved on.
It also kept things soft and flexible.
Of course I tested to snaps in my basket to make sure they were conductive before sewing them on.
I grabbed some good old white thread, a glue gun, and velcro and did a quick job securing everything in place before heading over to play with code.
I think that this seems like the perfect use for that open PIN.
More experimenting ahead --
