Engineering Design Algorithm 1)Identify the problem or design objective 2)Define the goals and identify the constraints 3)Research and gather information. 4)Create potential design solutions. 5)Analyze the viability of the solutions. 6)Choose the most appropriate solution. 7)Build or implement the design. 8)Test and Evaluate the design. 9)Repeat all steps as needed.

ENIAC: 1945: Performed 5000 Multiplications/sec

In 1947: Bill Shockley, Walter Brattain, and John Bardeen invent the transistor. They won the Nobel Prize in 1956.

Jack Kilby invented the integrated circuit in 1958 at Texas Instruments

Quotes from Gordon Moore (in 1965) With unit cost falling as the number of components per circuit rises, by 1975 economics may dictate squeezing as many as 65,000 components onto a single silicon chip. Integrated circuits will lead to such wonders as home computers or at least terminals connected to a central computer automatic controls for automobiles, and personal portable communications equipment. The electronic wristwatch needs only a display to be feasible today. Gordon Moore, “Cramming more components onto integrated circuits”, Electronics, Volume 38, Number 8, April 19, 1965.

Rube Goldberg Machine It is a pencil sharpener that operates as follows: Open window (A) and fly kite (B). String (C) lifts small door (D) allowing moths (E) to escape and eat red flannel shirt (F). As weight of shirt becomes less, shoe (G) steps on switch (H) which heats electric iron (I) and burns hole in pants (J). Smoke (K) enters hole in tree (L), smoking out opossum (M) which jumps into basket (N), pulling rope (O) and lifting cage (P), allowing woodpecker (Q) to chew wood from pencil (R), exposing lead. Emergency knife (S) is always handy in case opossum or the woodpecker gets sick and can't work. [rubegoldberg.com]

1.Transmission bearings cascade into each other and fall striking a 2.Camshaft and wheel which spins to hit a 3.Exhaust assembly balanced on a crankshaft assembly, which spins striking 4.Valve stems which cascade down the front bonnet leaning on an alloy wheel rim and strike an 5.Engine oils dipstick which was being bent by a throttle actuator shaft and the engine cam cover, the dipstick whips and hits the 6.Radiator which has been precariously balanced, causing it fall and strike 7.The first wheel and tire, which was balanced on the water pump housing. The wheel rolls bumping cascading into additional wheels which eventually bump 8.A brake disc off onto a release cable whose tension causes the 9.Rear seat to be released sending 10.A suspended windshield wiper travelling down a cord only to knock over 11.A tin of engine oil which pours onto a platform causing 12.Several bearings to fall into a 13.Cylinder liner, sitting atop the cylinder head assembly, The additional weight of which causes the car battery to see-saw up and make an electrical connection starting the cooling fan 14.Which rolls along disrupting a ring which slides down a series of rods, dislodging the balance muffler which rolls away bumping into a 15.Rear suspension link, which swings and knocks the rear suspension link launching a 16.Rubber grommet which strikes 17.A tire precariously balanced on the cars front end body which falls onto 18.A cable suspended between two disc brakes causing 19.A cascade of con rods causing the 20.Cylinder liner to roll and make contact with the rolled up window of the left hand door 21.Which opens allowing it roll and be lowered onto a series of 22.Indoor grab handles which lower it onto 23.A battery, which it completes a circuit causing the windshield washer pump to spray fluid which is sensed by the 24.Automatic windshield wipers, which crawl along the floor, bumping into 25.The handbrake lever, whose cord causes a mobile of windows to rotate and blow over the 26.Rear tool tray liner panel which falls dislodging a 27.T-bar entwined atop a suspension coil spring causing it to rotate down the spring until it makes electrical contact with a battery causing it to turn on the car’s CD player 28.Whose speakers are positioned below the rear window with a suspension spring balanced atop it. The sound makes the suspension spring roll off 29.Where it lands on a brake pedal which changes the tension on the rear shock absorbers causing a solenoid to strike the trunk close button on the ignition key 30.the closing trunk changes the balance of the vehicle causing it to roll down its platform thereby displaying the final advertising banner. * reference ( for a discussion of the “machine” including the names of the automobile parts in the video )
