MIT electrical engineering lecture, Professor Sussman explains how a mechanical watch mechanism relates
to an electrical oscillator circuit consisting of resistors, capacitors, and inductors. Sussman is a
life member of the American Watchmakers-Clockmakers Institute and exploits his expertise by demonstrating
via close-up camera how various parts of the watch function while explaining how they relate to electrical
components. This goes far beyond the comparatively lame textbook and classroom examples most of us have
experienced in college.
the U-2 is still the highest-flying airplane in the world. Its real max altitude is classified, but
in this video James May of the BBC's Top Gear
has the privilege of riding on the edge of space, at 70,000', where the Earth's roundness, and the thickness
of the atmosphere separating terra firma from the black void of space is apparent. He comments how it
is hard to not become emotional over the reality of seeing the home planet from such a vantage point.
you remember when the Rubik's Cube first came out? It must have been around 1980 or so, because I was
in the USAF at the time. Don Hicks and I were the only two guys in our radar shop who took the challenge
seriously, and I do not recall who solved it first. Neither of us got as good as this guy in the
video, but we could whip through a cube in pretty good time. Eventually I bought one of the cubes with
16 squares on a side. Never did solve it.
I have to admit to never
having heard of this band, OK Go. They and a cast of many created a pretty amazing, giant size Rube
One of my favorite parts is the bowling ball being launched across a fairly large
distance and hitting its target to continue the machine's repertoire of imaginative gizmos. The video
is nearly 4 minutes long.
is a video of some pretty spectacular lightning strikes on the world's tallest building - the Burj Khalifa
Dubai. It was made on January 11th of this year. Handling 50,000 amps of current is no easy task, especially
in an environment packed with sensitive electronics. I have not seen any reports of systems failing
during intense storms, but that is no guarantee it has not happened.
This is what might
be considered the mechanical engineer's equivalent of an electrical engineer's cycles-per-second-to-Hertz
converter. Come to think of it, though, there might be a huge market for this device under the new "green"
energy policies. Maybe someone can package it commercially in the form of a light switch, calculate
a carbon offset value, and collect millions in tax credits. Our Congress would be dumb enough to allow
A few years back, MIT began a program of publishing videos of many full courses, including
the electrical engineering curriculum. This particular video from course number 6.002 covers MOSFET
On-screen captioning follows popular Professor
performance as he speed-writes/draws on the multi-layered electric chalkboard. A full transcript is
provided for each lecture. It is a great way to brush up for an impending interview.
Intel has made
a few pretty good videos in the last couple years. The best, IMHO, was the "Our rock stars aren't like
your rock stars" commercial starring Ajay Bhat.
This circa 2007 video, Wanted: Moore's
Law for Another 40 Years, promotes their
breakthrough. Background music is Bobby Fuller's 1965 hit "I Fought the Law and the Law Won." This is
very non-PC (guns used - a surprise coming out of the belly of the PC beast).
the looks of this video, maybe the demolition experts should have budgeted for the extra sticks of dynamite
or C4. One building fell to the ground whilst the second assumed the position of a popular tourist location
in Pisa. Given the notoriety of the failure (including this mention), all the engineers on the crew
are probably now helping to maintain track for the
Beijing-Lhasa Express high speed rail system to Tibet.
is a case where getting two for the price of one is not a good deal. In July of 2006, a Chinook helicopter
struck the 1000-foot transmission tower for television station
WFXL, in Albany, GA. The tower had to come
down because it posed a risk to the WALB tower standing
next to it. Experts were called in. The WFXL guy wire charges went off as planned (visible in the video)
and things were going well... until a wire from the collapsing antenna got tangled on the WALB tower
guy wire. Well, that's one way to take care of the competition.
Nokia N95 smartphone drive this LEGO Speedcubing robot (big sport in the robotics nerd world). Constructed
entirely from LEGO parts, it includes a vision system for ascertaining the cube's state while solving
a 3x3x3 Rubik's cube from any start position in under 20 seconds, including the initial image capture.
Thanks to a passionate, dedicated user base, LEGO has come a long way since introducing the blocks in
1949. They now carry a complete line of robotics devices, including processors, motors, and vision devices.
Here is a nifty bit of trivia for you:
LEGO is an combining
of the two Danish words leg and godt, meaning play well.
October, students at the University of Southern Illinois launched a weather balloon laden with experiments
and a video camera. Gusty winds made the inflation process a bit dicey, but the flight completed as
planned. You can watch the balloon finally burst at 90,000 feet against the black background of space.
The local electric company help retrieve the craft from a tree about 110 miles away.
