This motorized tripod head can be used for moving video shots and for rotating time-lapse videos. If you want to record a video you must set TIME to 0. The variable MOVE represents the speed of the rotating head (5-100).
Today we present to you Lego, which plays a few movies melodies on the xylophone. The principle of operation is very simple. The tread is rotated by the handcrank or motor, pins raise the sticks striking the corresponding xylophone bars.
This module was inspired by classic Abyssinian pump which sometimes is using by Mikołaj's grandmother. We moved it into the Lego GBC world module which pulls up the balls. Our pump is 8 balls high. We can pump balls by hand or using a crank connected to the lego motor.
Today I would like to show you a simple lego gadget which make your coffee better. My lego milk frother is very simple. You only need 8293 set and few pieces to build it. Medium motor and gear give about 1200 rpm. This is not much but enough for milk foam. Bon Appetit!
I was thinking, for a long time, about GBC module using a switch to change the direction of the motor rotation. After many tests and making several prototypes, finally I can introduce a properly working contraption.
