Websites with Lego Technic TUTORIALS

[DLuders]

Here are some useful websites containing Lego Technic TUTORIALS. I'm sure there are others; feel free to add more.

Sariel's "Gears Tutorial" -- http://sariel.pl/2009/09/gears-tutorial/ . "A complete tutorial on Lego gears, their advantages and disadvantages as well as the basic laws of mechanics that apply to them. Updated on February 19th 2010."

"Physics of Lego" -- If you click on the menu along the left side of the following webpage, it covers "Motors, Ratchets, Multiplexors, and Pneumatics" : http://www.mapageweb.umontreal.ca/cousined...sics/index.html .

Jetro's "LDraw Tutorial" on TechnicBRICKS -- Part 1 ( http://technicbricks.blogspot.com/2009/10/...ial-part-1.html ), Part 2 ( http://technicbricks.blogspot.com/2009/10/...ial-part-2.html ), and Part 3 ( http://technicbricks.blogspot.com/2009/10/...ial-part-3.html ).

Thanks for mentioning the tutorial... I really need to make some time to work on parts 4,5 6...

For those who really can't wait, much (though not all) of the information has been published in Hispabrick Magazine, which is available in Spanish and English at www.hispabrickmagazine.com

In the latest issue (007) we also had permission from Sariel to include his excellent Gears Tutorial

"Sariel" (Paul Kmiec) just posted his "Gear Ratio Calculator 2" on his excellent website. Read about it at http://sariel.pl/2010/04/gear-ratio-calculator-2-released/ ; the actual calculator is at http://sariel.pl/tools/ratios/ . One can place any type of "Driver Gear" and "Follower Gear" on a 6x6 hole grid, and there's a pictorial output and some data like:

"The gear ratio is 1.8:1"

"The speed is increased 1.8 times.

The torque is decreased 1.8 times.

The follower gear rotates 1.8 time per each revolution of the driver gear."

Cool!

Have a look at this website too: http://nicolas.lespour.free.fr/_content/ttools.html

It also features a gear ratio calculator, but in this case you can select the motor you power the gears with and the power source you use. The site is intended to calculate several parameters for Trial Trucks, including clearance
