Morse code - Telegraph

Telegraph and Morse code - Civil war inventions

PURPOSE:
To make a mock morse code generator using lamp and buzzer.

HYPOTHESIS:
.Using buzzer can communicate in morse code via sound.
.Using lamp can communicate in morse code via light.

MATERIALS:
Buzzer
Lamp
Battery AA and battery case
Wires
Switch

CIRCUIT:




INSTRUCTIONS:
1. I used a photo frame and a cardboard. 
2. Poke holes to find place holders for battery and lamp and switch and buzzer.
3.Connect a buzzer and lamp in series with +ve of the battery.
4. Connect a switch to -ve of the battery and other end to the lamp.
5. Use the switch to hold for more than 2 seconds to send a DASH and a hold a second to send a DOT.
4. Repeat steps 5 multiple times with multiple combinations and send your encrypted messages in morse code.
5.Write down the results.

RESULTS:
1. Sender sends messages translated in morse code and receiver receives them and translates them.

CONCLUSION:
1. As long as both sender and receiver knows morse code they can share secrets using this communication method.

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...

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...
