This project displays four moving images :

A US FLAG
A Purple/Red Throbbing Heart
A Yellow Eye Opens a Blue Iris Looks Left & Right then Closes
A slowing Flasher of three colored Letters 'M' , 'J' , 'T'

Men's Jewelry and Toy.

Because we (Men) will wear Jewelry and because we (Men) Toy with almost anything. Here presented is a programable LED RGB UFO graphic COMmunicator. The MJT composed of a Stamp micro-controller, a 5x7 matrix RGB LED 'brick' and some switches to operate this Ible contraption.

Step 1: Simple SCHEMATIC

Circuit Description
This is a micro-controller Stamp operating a 5_column by 7_row by 3_LED_per_cell matrix RGB display. The Stamp uses a simple basic program running fast enough to multiplex red green and blue individual LEDs to create color images on the 5 x 7 display area. A 74HC4017 IC_U1 is clocked by line P0 (pin5) of the Stamp to sequentially multiplex the seven rows. U1 is wired to self reset on every 8th rising clock pulse. U1 can also be forced to reset sync by holding the clock line high for a time.

Parts List
BS2 Stamp from Parallax.
U1 a 16pin 74HC4017 IC
U2 actually an MC7805 a TO-220 5V regulator
D1 & D2 signal diodes
R1 actually a 33K resistor
R2 100K resistor
DIP1 & 2 actually 100 ohm resistors
RGB LED matrix
SW1 & 2 momentary push buttons
Wire-wrap IC sockets Jameco

See the thin plastic shirt pocket support for wearing the finished MJT display.

Step 2: Short VIDEO

This short video demonstrates ( in poor camera color ) a Red, White and Blue USA Flag to indicate country of origin to an alien. Followed by a brilliant red and purple ( very poor camera color ) throbbing heart to indicate friendly intentions. Followed by a single yellow eye with blue iris looking left, right and blinking to indicate a desire to look around the alien craft. Finally a red letter 'M", a white letter 'J' and the Yellow letter 'T' signing as the MJToy.

Step 3: DETAILS COMPONENT SIDE

Good views of component layout.

Step 4: WIREWRAP SIDE DETAILS

Note the wire-wrap pins are cut short for reducing thickness of the circuit board and some are soldered and bent over to hold the wiring together.

Step 5: SOFTWARE

Parallax the maker of the Stamp micro-controllers provides a very good and FREE windows editor. Just down load the editor and with the following text cut and pasted into it. You will with a simple RS232 or USB to 4 pin cable ( Construct it yourself or buy from Parallax site ) be communicating with aliens soon.

A text file of this basic program ( S.BS2 ) is also included.
