While the video above simply has the LEDs oozing through the rainbow colors (straight out of Adafruit's example code for the LED strip), my hat was also equipped with a bunch of sensors to allow it to respond to the world around it. Check out the two other operating modes below:
So, you can count me as one of the multitudes of folks adding LEDs to hats for good fun at parties! It may be simple, but it's SO MUCH FUN!
Interested in making your own world-responding LED hat? Well, below are a couple pictures showing some details on how I put it together.
- Hat: one from my closet
- Addressable LED Strip: Adafruit, 60 LEDs per meter.
- Arduino: Mongoose 9 DoF IMU from cldevices.com.
- Battery Pack: 3xAA pack with on/off switch from Adafruit.
- Thread and Twine: from my sewing basket.
One of the hardest parts for me was figuring out how to attach it all to the hat. So, on my wife's very good suggestion, I used a little twine to tie the battery pack through the holes in the wicker hat and loops of thread to "sew" the LED strip to the hat at select locations. Easy! And, it was surprisingly effective. (Maybe that's because my wife also helped greatly in actually doing the attaching!)
So, that's my story. It was a great hat. It was also (for me) a fun make up job. Another set of thanks go to my talented make-up artist, Ange!
