FINAL PROPOSAL: lever arm/membrane wall section
the "death match between lever arm and membrane" enacted with light.
the final model envisions itself at a 3' width, approx. 6" depth, and 3' height. the input will be received from infrared sensors. the processing will be on/off translated from detected movement. the output will be: lever arm deforming membrane. this deformation will follow to actuate aperture in the membrane wall. the wall interior is lit. light will reveal itself when movement is present.
the materials:
.010-.015 gauge flexinol (6"-12")
infrared sensor (2)
low power lamp
fiberglass rod (1/16"-5/32" diameter) (up to 3/4" for substructure)
silicone tubing (fda grade 3/32 x 7/32)
silicone sheet (commercial grade, red, durometer 40, 1/32")
stainless steel circular clamp
lightweight cardboard composite
silicone rtv adhesive
for rewiring breadboard:
irl520 mosfet
220 ohm resistor
external power source
both the lever arms and membrane will be structured off of a fiberglass rod substructure. an enclosure for the light will be constructed with light-weight cardboard composite.
CRUX: the project will run four wires. the necessary ampere current will be achieved by rewiring the breadboard with the irl520 and including a 220 ohm resistor to protect the stamp i/o pin. the external power source has not yet been determined.
the below schematic illustrates the rewire. if anyone may shed light/offer technical support in instrumenting the new schematic-PLEASE OFFER ASSISTANCE. we would gladly repay you.
