This gearbox solves the problem of needing three lego technic motors to remotely control a car with 3 functions namely driving, steering and gear changing capability. The lego gearbox implements two functions at once by exploiting the direction of rotation of the driving motor and ...read more

This video shows the design and construction of an 8 speed manual gearbox inspired by the Lego Technic Ferrari 488 GTE model that has come out in 2021. The lego technic set is called set #42125 Ferrari 488 GTE "AF Corse #51".

The gearbox gearing ratios closely approximate the ge...read more

This video presents a Lego Technic version of the spinning top battle game "Beyblade". A Lego Technic launcher for spinning tops made out of Lego is demonstrated and a number of battles are fought between various top designs. The launcher uses a high speed buwizz buggy motor to drive th...read more

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

A lego technic 2 speed automatic gearbox is presented. The point of difference of this automatic 2 speed gearbox is a secondary booster motor is activated once the torque detector senses a large enough torque on the output of the automatic gearbox.

The second motor is turned on by a pole ...read more

Here I present a lego technic 8 speed gearbox that does the seemingly impossible - creating eight speeds using just two levers. Normally two levers are used to create a lego 4 speed lego gearbox - however this design allows for 1 of 8 different speeds to be selected.

Each lever drives a s...read more

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

This strong and versatile four speed sequential lego gearbox uses the new "Change over rotary catch" (from the bugatti chiron, 42083) component to smoothly select from 1 of four speeds using a single lever. The gearbox implements 1st, 2nd, 3rd and reverse speeds. The rotary catch is kep...read more

Here I present a 256 speed gearbox controlled by 8 switches. This design is based on a 2 differential N to P gear ratio design presented in one of my other videos. The gearbox allows 256 different gearing ratios to be selected including 1:44, 1:34, 1:33, 1:32, 1:28, 1:27, 1:24, 1:2...read more

This video shows a Lego Technic 7 segment LED panel that can count upwards or downwards using a track driven program via tow ball pins. The LED display can be programmed to show digits or one of 17 different letters to make a sequential display to animate small text messages.

The panel is...read more
