Cardboard Pinball Machines

This year we are making Pinball Machines to study Transfer Of Energy. I made special models for things that we are going to use in our Pinball Machine, Revenge of the Robots.

I made a rocket ship that when you knock down a landing strut, it will have a propeller spin. I also made a mini Pinball Machine out of Legos with an idea for the flippers. I also made a big button machine that uses aluminum foil to complete a circuit. I also made a robot head that has a button to make sound and LED's light up



Prop 1:
Hit up, light up

Materials needed:
Aluminium foil
Battery and Battery case
Lamp and Lamp base (3v preferable)
Wires
Cardboard

Method:

Cut the cardboard to a box shape, mount the lamp base using screws
Paste two rectangular aluminium foil on front side of box in both ends they shouldn't touch
Connect one of wires to battery case and another wire to one side of aluminium foil
Connect another wire from battery to another side of aluminium foil.

Poke two slit on the lamp box and also another box.
Connect two cardboard slits through them so that both boxes and slid through to touch each other

Make another box and cover it with aluminium foil on one side where slids are present.

Now when you push the box and alumimium foil of box 2 touches box 1, the circuit is closed and lamp will light up.

In order to mimic grandeur lamp we used Christmas ornament over the lamp.

Gears and basic concepts

-
Image
Gears / Cogs: Gadgets that can change speed, torque,direction of power source. Principle is similar to that of levers. Gear ratio = No of teeth (Follower)/No of teeth(Driver) Gear: Here the driver gear moves the follower gear. Both have same number of teeth and gear ratio is 1.  If Driver rotates in clockwise then follower rotates in anti-clockwise or vice versa.   Perpendicular Gear: Change the direction of rotation from front to top. Front clockwise, top anti-clockwise viceversa Orthogonal gears: Change the direction of rotation from front to right/back to left . Front-Clockwise, Right -anticlockwise and vice versa Gearing up: Driver gear (teeth) > Follower gear (teeth) Driver gear(speed) < Follower gear (speed) Driver gear(torque) > Follower gear(torque) Gear ratio = No of teeth(Follower)/No of teeth(Driver) = 6/14 Gearing down: Driver gear (teeth) < Follower gear (teeth) Driver gear(speed) > Follower gear (speed) Driver gear(torque) < Follower gear(torque...

Wheel and Axle-Connections of parts

-
Image
 A wheel and axle is a simple machine, and a very useful one at that. However, not all forms of a wheel and axle are equal. Let's look at the four cases: Wheel is fixed, Axle is fixed, Body is fixed                         In this case, the wheel, axle, and body are all fixed. This case will never work, because the wheel, being attached to the body, cannot rotate at all. This case is similar to, say, pushing a round pair of headphones across a table. The earphones, despite being circular and looking like they are a wheel, will not rotate and will merely slide. _________________________________________________________________________________ Wheel is not fixed, Axle is not fixed, Body is not fixed                    In this case, everything is free moving and does not have solid connections. When you push this, it will spin, but it will be highly unstable. The reas...
