Hello these are the instructions to a ball gun that I made.
It is a little tricky to make and the balls don't go very far but it is still pretty good.
P.S. You don't need all of a Nxt 2.0 set but you do need the ball launcher that comes with it apart from that all you need are cables, a touch sensor and of course parts.
Please Comment but more importantly enjoy!
Step 1: Motor and Brick
In this part there is the motor and the brick, (you put the brick on in the end).
Step 2: Trigger
This is the trigger, it is pretty simple.
Step 3: The Launcher Thing
This is probably the most tricky part.
Step 4: Laucher Part
This is where the actual launcher part is put on.
Make sure that the stick goes into the back of the launcher because this is what pushes the balls out.
Step 5: Launcher Moving Thing
This is the simple part that makes the launcher shoot the balls.
Step 6: Supports
This step is basically to make the gun more steady. But don't skip it!
Step 7: Attaching the Nxt
This is were you simply attach the brick (Nxt) to the gun.
I'm sorry that I haven't done the the programming earlier but here it is.
The touch sensor port will might not be right as well as the motor port so check that if it doesn't work and if it still doesn't work then plz tell me.
