K'nex Ball Machine Lift: Giant Ball Catapult





Introduction: K'nex Ball Machine Lift: Giant Ball Catapult

About: I'm french, I live in a house, I love build with K'nex and Arduino, I have a YouTube chanel, and for Halloween, my garden become an haunted garden...

This is my new lift, the Giant K'nex Ball Catapult, it shot to a distance of 4 meters (because my room is too small), it only contains a motor, it's totally automatic, the arm is tracted by a nylon cable, but the shot is very hard to regulate, because the catapult shot creates a role-back, and the elastics extend. But the final result is just awesome !!!

I could give you the instructions for build it, but this lift is (In my opinion) the must dangerous K'nex ball lift ever !

    Thanks, I actually make instructions for build a V2.

    This is actually pretty awesome. Regardless if you post instructions or not, real well done. Didn't think such torque could be achieved with a standard red motor (mind me, I haven't touched K'NEX in a year).

    I think I can upload instruction after Halloween.

    Please be patient :-)

    All right, I can think about it. ( sorry for my bad English :/ )

    Hi, I've started to make instruction, but it's loooooooong...

    That seems dangerous, and I like it!
