The hoodie has a 9 x 9 matrix of WS2812B LEDs: 9 rows of 30/m strips left over from the Tardis. It’s driven by a Teensy 3.1 with a 12000mAh LiPo battery. I sewed the LEDs onto a t-shirt which I then cut the back off of and stitched into the existing seams on the sweatshirt. This technique gives it a completely seamless appearance. When the LEDs are off, it looks like a normal sweatshirt. I unfortunately haven’t had time to write any pattern code for the sweatshirt specifically. From running the Tardis code on it I’ve learned that the patterns that feature a lot of pixels completely off look the best since it makes it harder to tell the extents of the pixel matrix. I added an XBee socket to the controller as well so I could pick up the beat telemetry data from the Fuzzyland system.
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.
