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!
Lego Technic RC Forklift
Here I present a Lego Technic Remote Control Forklift model. The model uses articulated steering implemented with a Power Functions Servo motor, and is powered by a PF Large motor. The forks are raised and lowered with two PF medium motors driving worm gears which in turn drive via a 24 tooth clutch gear onto a sprocket wheel pulling up a track connecting the forks. The Forklift is demonstrated in action picking up boxes and flipping Lego Technic cars.

Lego Technic Omni Directional Vehicle v2.0
This is an improved version of the Lego Technic Omni Directional RC Vehicle v1.0 (https://youtu.be/crj3kOiSmHg). Several improvements are made in this model mainly around the mode switching from driving forwards and backwards to rotating on the spot. In the previous model there was a lot of gear ...read more
Lego Technic Omni Directional RC Vehicle v1.0
This Lego Technic RC vehicle is modeled on the Roomba vacuum cleaner from iRobot. The Roomba can drive forwards, backwards and rotate on the spot. This RC lego technic model attempts to do the same but with four wheels instead of two, similar to a supermarket trolley. The vehicle can switch betwe...read more
Lego Technic Single Motor Tank
Here I present a lego technic tank driven by a single lego power functions motor. The lego RC tank can be controlled remotely using a single remote channel and driven forwards, backwards, and steered left and right. These functions are implemented by using a single large PF motor and exploiting t...read more
Lego Technic RC 3 SPEED CAR - change gears, drive and steer using remote control
An improved version of a lego technic RC 3 speed gearbox is implemented into a remote control lego car. This video shows three main improvements over the previous gearbox design. The first is an improvement is to replace the 90 degree bugatti stepper with a PF servo motor reducing the gearb...read more
Lego 2 speed automatic car. Part 1
This video explores the use of the lego technic "smoothly switching 2 speed automatic gearbox" inside of a test car to see how well it works to climb up a ramp.
The gearing ratio of the 2nd gear of the 2 speed automatic gearbox can be set using a manual 4 speed gearbox to choose...read more
LEGO Technic MOC: 1023 SPEED CAR
A 1,023 speed gearbox has been built into a Lego Technic remote controlled car chassis. The car can be steered and driven via remote control using two channels. The gears can be manually changed using ten selectors that drive ten differentials. This allows for one of 1023 different speeds to be s...read more
Lego Technic Powered Up 3 Speed Automatic Car
This video presents a new lego technic 3 speed automatic RC car. The gearbox uses the lego technic powered up hub and 3 motors to drive, steer and switch gears. The car's 3 speed automatic gearbox has 3 forward speeds with gear ratios 1:1, 3:5 and 1:5 and has been programmed us...read more
