How A Geek Dad And His 3D Printer Aim To Liberate Legos. Scienza Ludica - Play Optics with LEGO. The basic elements of a fairly complete optomechanical kit based on the use of LEGOa is presented.
Through a careful exploitation of the many standard LEGO elements, and adding a few new simple components made of plexiglass, we demonstrate that almost all of the mechanical parts of an optical setup can be built with little effort and at an extremely reduced cost. Several systems and experiments are presented, mainly in the fields of optical filtering and interferometry, to show that the proposed mountings are perfectly suitable for didactic purposes, and can often be employed even in more demanding scientific applications.
Keywords: Education in optics, optical mounts, modular systems. In professional optical equipments, mechanical components make up a sizeable part in terms of cost, weight and size. Some of the basic components of an optomechanical setup, like tilters and rotators, are already included, although usually in a very raw version, in commercially available LEGO kits.

LEGO Gear Combinations. LEGO Gear Ratio Calculator. Technical Fundamentals. Gears Fundamentally, gears are devices which transmit rotational motion from one axis to another.
Certain types of gears may also result in translational motion. There are dozens of different types of gears in industry, only a few of which are replicated in LEGO®. The existence of LEGO® gears actually predates the Technic or Expert Builder lines and goes back to the Samsonite gear wheels of the 1960's. The different types of LEGO® gears and their basic function and usage will be explained below. Gear Ratios In the simplest case, a set of gears results in the same rotation speed on both the input and the output axle.
So what does it mean to have a gear ratio of 3:1? When you use gears to make something rotate faster and produce less torque, it is called "gearing up". Spur Gears Spur gears operate on axes which are parallel. There were some spur gears made before Technic and Expert Builder even existed in the 1960's and 1970's, but those are not covered by Technicopedia. Bevel Gears. Mindstorms.com. Mindstorms NXT Review. This is the first in a series of mini articles that will take a look at the internals of the new Lego Mindstorms NXT Intelligent brick.
In these articles I will take a look inside the NXT Brick what it is, how it works, and what makes it run. Check out part one of this series about the hardware inside of the NXT Intelligent Brick. Lego dimensions. Adapterz LLC.
