We originally sewed all of the electronic components into the helmet head straps. This would have made for robust design even if the construction hat was hit. We found, however, that the resistance of the thread was too high and the battery voltage dropped an unacceptable amount before reaching the motors and the arduino. Therefore we switched to the conductive tape version featured above.

Other construction features of note are the way we connected the pager motor to the rest of the assembly. The pager motor vibration poses particular problems for most solder joints and epoxies as the connection may eventually fail from fatigue. The specific mounting used in this project features threaded connections between motor and conductive fabric which are held in place by solder acting as beads on either side of the motor leads. The choice of neoprene fabrice was not accidental and the fabric absorbs the vibration enough that the module can be taped to the helmet.

We have provided two sample codes to turn on and off the servo motor and the pager motor.

• Arduino: We're using a Lilypad Arduino, which has sewable leads-- ideal for wearable devices

Need a spidey sense? You've got it! Need to get out fast? Fly!

This hat has it all. A sidekick can give your spidey sense a jump start or your distressed citizens can help you locate them with the awesome "Save Me" (c) application. Snap in your helmet and go go gadget wings!

• A "Spidey Sense" implemented as a pager module

• A "Fly Module" implemented as an aerodynamically modified servo motor

• Arduino: We're using a Lilypad Arduino, which has sewable leads-- ideal for wearable devices
• Battery: We used a rechargeable 3.3v battery connected to a circuit that outputs 5v to power the Lilypad and motors. It's essential for there to be a good connection (low parasitic resistance) between the battery leads and the power of the Lilypad.
• Bluetooth: The bluetooth module, which connects to the Lilypad, allows the Arduino to talk with the Android using the Amorino Library
• Wearable: We attached all our components to the inside of a construction helmet using stick-on velcro and conductive tape to connect the circuitry. Helmets has built-in room on the top, which never touches a wearer's head.

Hi all,

Sorry I missed meeting you today. I just thought I would activate this space as a way to organize our work if desired. Please feel free to use :)
