Jacob's ladder project ran in the December 2002 Nuts & Volts magazine.
Building this fascinating high voltage device is a lot of fun! This
Jacob's ladder project allows you to create the excitement of high voltage arcs
safely on your desktop. The circuit is powered by a 12-volt DC battery pack
and outputs over 30,000 volts. The circuit design allows the repetition rate
of the high voltage pulses to be varied by a potentiometer on the front panel.
Each time a high voltage pulse is triggered, the light emitting diode on the
front panel is also activated. This educational project demonstrates the principles
of high voltage and is also a great attention-getter. Join in the high voltage

had the pleasure of attending the second annual Artbots Robot Talent Show held
in New York City (www.artbots.org
The Robot Talent Show took place at the EYEBEAM Gallery (www.eyebeam.org) on
July 12-13, 2003 as a part of EYEBEAM's summer robotics festival called ROBOT.
The Artbots show featured the work of 22 artists and groups from six countries.
It was a great success with over 2000 visitors, as well as local, national,
and international press coverage in print, television, and on the web. EYEBEAM's
goal is to, "engage a cultural dialog at the intersection of the arts and sciences
and to forge an understanding of their relatedness".

Visit the Eastern Canadian Robot Games webpage:
Eastern Canadian Robot Games (www.robotgames.ca) were held on November 15 and
16, 2003, at the Ontario Science Centre in Toronto Canada. There were 10 different
categories of competition, with 150 robots created by close to 200 competitors
who came to do battle from areas all over North America. There was a wide range
of competitions from four different types of robot sumo, where the robots competed
to push each other out of a ring, to fire fighting, where robots searched through
a maze to extinguish small candles. The purpose of the robot games is for people
to have fun working with robotics, which is a great bridge to all areas of science
and technology. It gives them a chance to get experience with electronics, programming,
design and mechanical construction by building real working robots that accomplish
What is it that makes us human? Is it possible to create an artificial human
- an android? The human body, including the brain, is one of the most sophisticated
biological machines in existence. The design of the human body is so complex
that to build comparable machines our technology will need to advance significantly.
With our current understanding and technology we can only attempt to mimic
the form of the human body since it is impossible to recreate it at this time.
It is no wonder that man looks to nature for insight and inspiration when
designing machines. The idea of "reverse engineering" humans has fascinated
mankind for a long time. The concepts of how the human body functions have
proven to be extremely complex. For example, the human hand and wrist are
very complicated devices for grasping and moving objects but when implemented
in machinery they must be simplified in order to keep the mechanics and control
systems within a reasonable level of complexity...

is a correction to the wiring description of the potentiometers in the Hexatron
article published in Servo Magazine. The middle wire needs to be connected
to one of the outer terminals of the header connector. The values of the pots
should also be 5K ohms.
