I am currently a Senior at Oregon Institute of
Technology in the Electronics Engineering
program. I also plan to get an associates in Software Engineering
and Mathematics.
Additional experience includes, Autocad three
dimensional modeling, web page design
in HTML and JavaScript, Welding, and much more.
I started my senior project as an electronics engineer on
January 2, 1999; it is titled, "The Worlds Smallest Controllable
Aircraft." Progressive details can be seen by clicking the
circuit to the right.

As you may have figured out already, robotics/automation is
my thing. Completed as of June 10, 1999 is the
car called the SAVR. SAVR for Safe Autonomous Vehicle for Recovery
is directly to the right. This car was
built as a Junior Project in one of my classes. There has been
a test location sensor on board from a land based GPS system (see below).
The SAVR is used to retrieve in dangerous or inconvenient locations. Other
parts not shown are a claw, a storage deck and a role bar/cage.
The car is able to turn and travel in any direction,
including spinning in one spot. The remote range of the device ended up
being about 100 meters indoors and about 350 meters outdoors. As you
can see the car is digitally controlled by the laptop. The large black
thing on board is the battery. A suitably sized battery was not available
for the right price. On the bright side the car can continously drive at
about 17km/hr (10mi/hr) for more than an hour before needing to be recharged.

Moving in the communications direction, another class teaching me
the principles of special devices allowed for an opportunity to
test my new found knowledge. I studied laser diodes and photodiodes
for a day or so and felt that I was capable of building a simple
voice transmitter and receiver. The device can barely be seen to the
left, transmitter on the tripod and the receiver on the box. This
system was capable of transmitting line of sight up to around 50
meters (That was the furthest I could test it). The transmitter was
designed such that it could be plugged straight into any small headphone
jack and it would transmit the music to any 4 Ohm or greater resistance
speaker that you hook up to the receiver.

For a Digital Signal Processing class, we were to do something that
had to do with digital signal processing. I chose to do a psuedo land
based GPS system. My senior project is the Worlds Smallest Controllable
Aircraft, and if the aircraft ever landed somewhere that I couldn't see
I'd need to have some sort of method to locating it. This brought me
to this topic for a land based GPS system. There are two 915MHz receivers
that just pan the horizon, they intern respond to the computer, when asked,
from which direction they think the signal is coming from. The computer
having the directions from two known locations can figure out the exact
location of the aircraft.

Magnetic Card Reader. Reads and decodes the main track (track 1) of
magnetic strip cards, such as credit cards, ID cards, telephone cards,
and more. The information is decoded and displayed on any computer
with a standard serial port.

1GHz Wireless RF Transmitter. Transmits data at up 115kbps
and analog information with a bandwidth of up to 2MHz. Supports both
amplitude and frequency modulation. The transmitter as seen can
operate on four channels anywhere between 400MHz and 1GHz.
