Lego Technic Presenter
Sometimes you have to give a presentation. It is handy when you donít have to walk to the computer to switch to the next slide by tapping an arrow key. In reality, you have a presenter fort hat. But when you donít want to pay the money for it and you have Lego Technic, build it yourself!
About this creation
General data

2x PF M-Motor, for right and left arm
2x PF switch, used as an extension cable
1x PF battery box
1X PF receiver

Tekst & photoís



In this photo you see the whole presenter. It has a movable arm to increase the controller range. The switches are only used as extension cables. My real extension cables were in use in an other own designed Lego Technic model. Notice the position of the battery box, on top of the model. This is because the two arms press the keys of the keyboard indeed, but you have to have counterweight to press. The force downward should be greater than the force upward, otherwise the key is not pressed.



On this photo you see the arms of the presenter. One arm presses the -> arrow and one the <- arrow. They are equipped with rubber, so that they wouldnít slip of the key. In this photo you donít see the elastics. These are needed to return to the standard high position of the arm. Watch them at work in the video.
