WEEK 11 - FINAL PROJECT REVISION

















GOAL
A revision of my final project proposal, I've adjusted the output from a blinking shirt, to a flexible light membrane. I still need to schematize a heart monitor which I've received various advice about but need to get one working soon. (if I can't figure this out in the next 48hours I'll scrap the heartbeat input and go with something like a proximity sensor or light sensor.

DESIGN
A flexure lighting membrane which flexes with motor control to produce differing lighting conditions through tangent lighting effects.

COMPONENTS
MEMBRANE
1-Aluminum sheet, .03" thickness
2-Hinge Joint(maybe flexible bend joint)
3-Black Fabric for end closure

LIGHTING
Light source, central light source, or array of LEDs

MECHANICS
Flex system, pulleys cables,etc

ELECTRONICS
1-PHOTOTRANSISTOR NPN CLEAR 1206 (Digikey) OP522
2-ATtiny44A
3-STEPPER MOTOR - unipolar, bipolar?
4-Resistors, Capacitors, Voltage Regulators

PROCESSES
Waterjet

SCHEDULE
1-Design Sheet metal Fixture and layout cut files (today Monday)
2-Fab Board which controls Stepper Motor as output (Tuesday)
3-Fab Board which reads heartrate as input
4-Interconnect Stepper motor pulley system with flexible membrane
