Wireless CAN Yard Lamp
Control
by John Dammeyer
In addition to providing
a sense of security from intruders, sensor-controlled
yard lamps make it safer for you to walk on your
property after dusk. But they can pose problems,
particularly when a flash triggered by a nocturnal
animal awakens you from a dream. Other systems like
solar-powered lights have problems, too. Wouldn’t
it be nice to have more control over the technologies
you use? Check out the CANRF module John built for
yard lamp control. p.12
Keywords:
CAN,
RF, wireless, remote control, CANRF, PIC12C509,
communications

Palm-Enabled
Telescope
by
Steve Pope
Why can’t a Palm Pilot talk to a
telescope? That’s the question that prompted Steven
to attempt adding an IR port to his telescope’s
control unit. His effort has proved rewarding. Not
only can he control his telescope with his Palm,
but he has also created the possibility for Internet
access. p. 20

IR, Palm, telescope, GPS, IrDA, eZ80, protocol,

Your Own Four-Function Calculator
Mad Dash for Flash Cash Contest Entry
by
Daniel Ramirez
Daniel recently built his own electronic
four-function calculator, citing little more than
the spirit of invention as the impetus for his choice
of design. In this article, he presents us with
a thorough description of the project. p. 28

IR Sensing
by Ed
Nisley
Most professional engineers believe
they have an adequate understanding of IR sensing
concepts, but it never hurts to brush up on the
basics. In this column, Ed expands on many of the
topics he covered in a lecture last spring at the
Tenth Annual Trinity College Fire- Fighting Robot
Contest. Both seasoned designers and curious students
will find Ed’s straightforward commentary useful.

Flexible
USB-CAN Bridge
Mad Dash for Flash Cash First Prize Winner
by
Craig Beiferman
When Craig decided that he needed a cost-effective,
efficient way to control several microcontroller
circuits from one computer, he used a PIC micro
to design a USB-CAN distributed motion controller.
Like many do-it-yourself endeavors, this project
was born of necessity, so it’s inherently inexpensive
and easy to follow. p. 44
Keywords:
CAN, USB, PIC18F258, FT245BM, physical layer,
