Gearing Ratio Calculator
Check out the Beta version my Lego Technic Gearing Ratio Calculator Tool:
This tool allows you to upload your Lego Technic project .ldr file and analyse the gearing ratios between any two connected gears or axles. Currently supports most gears, axles, worm gears, some differentials, cv joints and universal joints. See the video tutorial on how to use it. It is a work in progress and I would love to hear your feedback on it. Click here to try it out.
Note: As of 25 Septemeber 2021 the tool supports CV joints, linear speed via the radius of the component and improves on the frame rate for higher numbers of parts in a model).
Technic Elbow Art
This is a tool to create "Lego Technic Elbow Art" - a series of intertwined elbow pieces as a single sequence. Choose your dimensions and search parameters and search for new dense solutions and set a record!
Download your Elbow Art as an .ldr file and build it yourself. Click here to try it out!
What are you currently working on for the Gearing Ratio Calculator Tool?
I am currently working on the following features in this order. I will release an update as each feature is implemented.
- New Differential: Parts 65413 and 65414
- Chain & Track Support. Allow tracks and chains to drive gears.
- Add more wheels and tyre components
- Power path support. Visualize the power path between the inputs and the selected output.
- Rotary Catch Support. otate a rotary catch to drive switch selection in gearboxes

Lego Technic Gearing Ratio Tool Update
This video presents updates to the Technic Brick Power Lego Technic Gearing Ratio Calculator tool specifically on underconstrained differential systems. These are systems in which the differentials are not fully constrained and therefore have 1 or more degrees of freedom within them.

How to mesh any two Lego gears on a regular grid!
In this video I analyze all of the eight regular lego technic gears and demonstrate how any two of them can be meshed on a lego grid.
A sum of radii chart is used to determine the possible diagonal meshing combinations. These are then combined with "intermediate" or "idler&...read more
How to use a Lego Technic Differential for your MOC Part 2: Computer Generated Solutions
In this video I present optimal computer generated solutions for designing 1:N (N=prime) ratios using a single Lego Technic differential. Insights and ideas are shown for implementing the 1:N designs in practice using Lego Technic liftarms with an example 421:1 gear ratio device. All the possible...read more
How to use a Lego Technic differential for creating prime gear ratios for MOCs. Part 1
Here I discuss techniques for creating prime number gear ratios such as 17:1, 19:1, 23:1, and 53:1 using a Lego Technic differential. Learn the mathematical relationship between the gear to create your own MOC desired ratios. Use this lego differential tutorial to design your own lego gear ratios...read more
