This story begins with a client. A well off lady who has a bit of an issue: She has difficulty interacting actively in society. We have created a device to better allow her to go to balls and parties looking as beautiful as ever while feeling more comfortable.
This device is in the form of an intricate mask to reflect the lady’s beauty. When there is not sufficient commotion and stimulus from conversation or the party in general, she is reminded to be present by flashing red lights and a soft buzzing within the mask. When the stimulus is at an acceptable level, blue lights stay on steadily and the mask is still
The circuit was designed to invert the input. The sound detector drives the gate of the first transistor. The drain of the second transistor is the inverted output which drives the gate of the second transistor. The second transistor is used to activate the actuators in the mask.
There are two layers to the mask both made of plaster coated cardboard and shaped with a dremmel. The masks are connected by 3/16 inch bolts and washers. The interior is coated with white faux fur, and in the middle is where the electronics lie. The exterior has RGB LEDs embedded and a covering of embroidered lace.
