DESIGN & DEVELOPMENT

MERGE MATRIX:
ABOVE: (Symbol A) + (Symbol B) = A new breed of Symbol.
A merge of designs between FUSE wearers works by the pixel color merge matrix below:
green + red = orange
green + orange = green
green + green = red
red + green = orange
red + orange = red
red + red = green
orange + red = red
orange + green = green
orange + orange = orange
CIRCUIT BOARD:
LEFT: LED DISPLAY CIRCUIT
On the left side
are the 6 buttons, labeled 'B1' thru 'B6', these are for editing the display.
The rectangular block top-left is the connector that connects to the Basic Stamp-circuit.
All-in-all there's only 8 wires running between the two circuits, and yet the Stamp can control 98 LEDs & some buttons in the other circuit!
ABOVE: BASIC STAMP CIRCUIT
Top left is a powersupply-circuit involving a MAX1674 chip. This
tricksy thing can actually produce a 5V supply for the Basic-Stamp
from a 3V battery.
Next to this is a similar circuit with another MAX1674, this one making a 3.3V supply for the LED Display-board.
The Basic Stamp itself is the big rectangle labeled 'U4', somewhat central in the diagram, and it has a serial connector to connect to a PC for (re)programming the Basic Stamp.
An infrared transmission approach for transmit and receive (like a TV-remote).
The Basic Stamp transmits infrared pulses, (a long pulse for '1' and a short pulse for '0', for instance) with an infrared LED, and AT THE SAME TIME it can 'look' for pulses using an infrared fototransistor (= light-detector), as long as the infrared-eye cannot see the pulses coming from it's own IR-LED but only the infrared pulses from the other Basic Stamp (whith which it is exchanging data).
The Basic Stamp program is written in PBasic.
WRIST BAND:
PIXEL DESIGNS:
5 ready made designs have been programmed into the basic stamp.
To do this the colours needed to be
converted into binary.
In this sketch beacuse the LED's are BI (having two states: red and green) each LED that is ON is a number 1 and each LED that is off is a 0. Where both RED and GREEN are 1 (on) the LED will appear ORANGE.
