![]() ![]() SSID is an unique 32 bit character identifier attached to the header of packets which are sent over a wireless local area network (WLAN) that acts as a password when a device tries to connect to the basic service set - standards imposed by IEEE 802.11 standards.The Adafruit CC3000 library conveniently has a function in the buildtest example to list the SSID (service-set identifier) results that we adapt for our purposes. For best hardware-to-software compatibility, it is recommended to use Arduino software 1.0.6 as opposed to the current version available, 1.6.4. In order to scan local WiFi, we used Adafruit CC3000 WiFi Breakout with the on-board antenna. NeoPixel LEDs, LilyPad LiPower, 2000 mAh battery, WiFi CC3000, LilyPad Arduino & LilyPad FTDI Wi-Fi Scanning: We used Velcro to hold the LED strips in place under the flaps, and an adjustable leather belt to attach the device to the wearer. The final prototype uses Chicago screws to hold the neoprene pieces together along with canvas strips which allow the device to drape down the wearers shoulder. ![]() Neoprene is a forgiving material that is soft but easily holds its shape, which gave us the flexibility we needed while finalizing our design. After visiting Discount Fabrics, we realized that leather is fairly expensive and difficult to work with, so we decided instead to use neoprene. Initially we wanted to use leather for the final prototype. Iterating quickly with cardboard, brass fasteners, duck tape, and canvas, we were able to hone in on a form factor that would fit on most shoulders and cleanly house our electronics. We began with paper prototypes to understand the initial form. We decided on creating shoulder armor because we wanted a wearable that would be bold enough to display at Burning Man or an event like Silicon Valley Fashion Week, but also simple enough to be worn around Berkeley. ![]() We started out the design process by deciding who we wanted to design for and in what setting. ![]() Velcro works great to secure things in a pinch.Īlligator Test Leads - Multicolored (10 Pack)įor quick testing and prototyping on the Lilypad. It is hooked up to the strip's digital input. This resistor aids in preventing spikes that could damage the NeoPixel strip. It is the recommended capacity as Adafruit states on their NeoPixel instructable. This capacitor helps smooth out the voltage across the NeoPixel strip. We were concerned with powering the LilyPad, CC3000, and NeoPixels so we opted for the 2 amp battery. This converts our 3.7 volts received from the battery to 5 volts to power everything! Yea! We used Velcro to attach and to secure the lights to the neoprene. We cut and removed the white housing from around the LED strip. It is suggested to use at least a 1 amp external power supply to power this properly.Īdafruit NeoPixel Digital RGB LED Strip - White 30 LED - 1m - WHITE The pins are connected to the LilyPad as suggested on the Adafruit instructable. The main board needs this to load and compile Arduino code on it.Īdafruit HUZZAH CC3000 WiFi Breakout with Onboard Antenna - v1.1 We also chose the main board over the LilyPad Simple Board as it has more pins. We wanted to use an Arduino that we could sew into the material, but this proved to be arduous. We used a LilyPad Arduino 328 Main Board for this project. Our original intention was to use leather to build this, but we opted for Neoprene because of it's interesting texture and flexibility. ![]()
