3.  This project is a prototype flexible display attached to a jacket that receives text wirelessly from a nearby computer and outputs it to an LED display matrix by multiplexing the text data through a series of 8-bit shift registers.

5. Display Component 8-bit Shift Registers LED Matrix units

6. Control Component Wireless Component To Display

7.  Arduino Code  3 functions  Get Input from Xbee ▪ Trim to display width  Convert input to display pixels ▪ Look up characters in table  Refresh display ▪ Controls clock signals and row updates ▪ Synchronized

9.  Construction took longer and got started later than anticipated  Ended up ordering parts later because of broken components

10.  Attached LED units to jacket sleeve  Soldered shift registers to PCB  Sewed bus lines from display to control with conductive thread  Attached Lilypad and Xbee with thread  Connected PCB and LED units  Attached batteries

11.  Single LED unit and single shift register  Added more units and registers  Changed from hardcoded input to dynamic strings  Added wireless capability  Polished timing issues and finalized wiring  Tested connectivity and voltage on jacket

13.  Working display  Working wireless  Ran out of time embedding on jacket

14.  No eInk or other integrated flexible display screen available  Individual LEDs too much labor  5x7 matrix units more manageable  Timing issues  Too much wiring  Thread doesn’t connect to pins easily  Take too much time to complete

15.  This project  Detatchable components for washability  More efficient screen  Better wireless  Applications  Doctors  Soldiers  Astronauts

16.  We used the IEEE 802.15.4 standard which specifies the media access control for low- rate wireless personal area networks (LR- WPANs) using the XBee Series 1 transceiver.

17.  User safety  Sharp edges  Exposed wires/thread  Possible heat dissipation  Waterproofing
