For the compass rose, I stitched the Adafruit neopixels together and hooked them up to the Adafruit Flora. Also connected to the Flora is a magnetometer/accelerometer. The magnetometer probably gave me the most grief. It turns out that if you want to use communications protocols (like I2C) on e-textiles, make sure the connection is SOLID! I became so frustrated with the magnetometer not talking to the Flora that I just soldered some wires instead.
Despite the frustrations, I’m pretty happy with how the bag turned out. This was also the first time using the Flora and I have to say, I love it! I can certainly tell that the folks at Adafruit put A LOT of thought into it. One little detail that made me really happy was strategically placing the SDA, SCL, power and ground pads so that you wouldn’t have to have any thread/wires cross. If you’ve been working with e-textiles for a while, you’ll know exactly what I mean! Seriously, Adafruit…thank you!!!
