Presentation of the new, speed control-enabled Power Functions handset along with a modification I’ve created to allow easy control of the tracked vehicles. Update: instruction added.
My first automatic gearbox, based on a design by Misha van Beek, but improved and simplified.
Two ways to make your 3 studs wide differential sit where you want it to sit, whatever load applied, and to deal with the half-axles’ tendency to slip out.
An idea on how to lock the new, 3 studs wide differential in a compact, reliable way.
A simple add-on to a regular differential, that locks it automatically whenever a slip situation occurs.
Idea of a linear gearbox extended beyond the usual 3 speeds. Features fixed input and output shafts.
Compact 2-speed gearbox, where gears are changed when the direction of motor’s rotation changes.
Very small 2-speed gearbox, that is rotated by 180 degrees to change gears.
