Posted by: engineerguyvideo

Video duration: 336 seconds

Bill uses a bucket of propylene glycol to show how a fiber optic cable works and how engineers send signal across oceans. More info at http://www.engineerg uy.com. You can translate captions at http://www.engineerg uy.com/translate
Hard drive teardown Hard drive teardown
Posted by: engineerguyvideo

Video duration: 304 seconds

Bill opens up a computer hard drive to show how it is engineered. He describes how the "head" reads the magnetic information on the disk; reveals how a voice coil motor and a slider controls the position of that head. He also discusses how smooth a disk must be, and briefly mentions a mathematical technique that allows engineers to pack more information on a drive.

How smoke detectors work How smoke detectors work
Posted by: engineerguyvideo

Video duration: 225 seconds

Bill takes apart a smoke detector and shows how it uses a radioactive source to generate a tiny current which is disrupted when smoke flows through the sensor. He describes how a special transistor called a MOSFET can be used to detect the tiny current changes.

Why the other line is likely to move faster Why the other line is likely to move faster
Posted by: engineerguyvideo

Video duration: 223 seconds

Bill reveals how "queueing theory" - developed by engineers to route phone calls - can be used to find the most efficient arrangement of cashiers and check out lines. He reports on the work of Agner Erlang, a Danish engineer who, at the opening of the 20th century, helped the Copenhagen Telephone Company provide the best level of service at the lowest price.

Video duration: 160 seconds

Bill takes apart a coffee maker to show how hot water is pumped through it using a "bubble pump." The use of this pump reflects an engineer's choice to have only one heating element to lower the cost.
Pop Can Stay-on Tab (slow motion) Pop Can Stay-on Tab (slow motion)
Posted by: engineerguyvideo

Video duration: 138 seconds

Using slow motion video Bill Hammack shows the ingenious engineering design of a pop can stay-on tab. To use the least amount of material it was designed to change, while in motion, from a 2nd to a 1st class lever.
IBM Selectric Typewriter & its digital to analogue converter IBM Selectric Typewriter & its digital to analogue converter
Posted by: engineerguyvideo

Video duration: 185 seconds

Using slow motion video Bill Hammack, the engineer guy, shows how
IBM's revolutionary "golf ball" typewriter works. He describes the
marvelous completely mechanical digital-to-analogue converter that
translates the discrete impulse of the keys to the rotation of the
type element. (This is the typewriter featured on the television series Mad Men.)
