This is my first attempt at a web site. So things,
will no doubt be, dynamic for a while. Change is
the only constant.

|Micro Processors & Micro Controllers :
Ultra Sonic Ranging
Analog to digital converter 8-bit
4 char, 16 segment LED displays
4 line by 20 char LCD display
Servo and stepper motors.
|Some projects :
Three asynchronous uCs interact via RS-232.
Four bit keyboard debounce/decode.
Azimuth & Elevation servo drive control.
Writes data to four, 4 character 16 segment LED displays via a 4 wire synchronous serial buss.
Sends commands to and receives data from the 2nd and 3rd controllers via a two wire RS-232.
Calculation of pedestal tilt using a dual axis accelerometer.
Calculation of range to target using an ultra sonic range finder.
Control laser pointer.
Provide elevation angle and range on request of the primary controller.
Read 8-bit DAC for SIN & COS of target azimuth, (rectangular).
Manage a FPU to calculate target azimuth, (polar), as arc tangent of the DAC values.
Writes data to a 20 char X 4 line LCD.
Used to drive a mechanical voltage charge pump. It did work boosting 5V to about 18V at around 20ma. Used 4
DPDT DIP relays controlled with an 8-bit shift register/latch. (It made me laugh.)
Watered my plants for 15 days last July when I was in Greece.
Measure the taper of an audio potentiometer.
Uses a stepper motor to turn a potentiometer in 7.5 degree increments then measures the electrical position of the
wiper from a RC time constant. Plots the results to a text box.
Digital audio bit stream switch w/ RS-232.
Four button keyboard debounce/decode.
Smart bit stream switch control.
Programmable Remote control via RS-232.
(Used for testing multichannel DSPs. Allows the selection from, 1-of-4 bit stream sources, (optical or electrical) for routing to test
equipment for measurement.)
Speaker switching for 3 X 2 ch w/ RS-232.
Push button control of speakers as three banks of 2 speakers. Allows remote and programmable control of a
speaker system. Includes EEPROM.

No goal, no scope, no exit strategy, no
idea. Just put a few Stamps on the
same frame and see what happens.
|Monitoring signals used to drive
the 4 character LED display at
the edge of the screen. Later I
would use four of them to
display angle and range
information produced by the uC
in the camera pod.
