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

-

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) Gear ra

= Gears Gears are a fundamental part of modern technology. Since their inception, they have been used to great effect, being used in tools from the smallest bikes to the largest cars. But, how do they work? Gears, in their most basic form, are wheels with "teeth" that can interconnect with other gears. The gear that is powered is called the driver, and interconnected gears are called follower gears. The two primary functions of gears are to transfer motion, and amplify force. Transferal of Motion is simple: the gear moves, and the teeth, interconnected, move the other gears as well. The basic principle of moving power is simple, and the more complex principles follow easily. The direction of the gears is important as well. When there is simply a driver and a follower gear together, they will always move in opposite  directions. However, when there is an idler gear between them, they will move in the same direction. Essentially, the gear next to a gear will move in the opposit
