Reverse Engineering of an Alarm Clock

1. Reverse Engineering of an Alarm Clock Matt Northam, Eric Packard, Michael Oshikanlu, Neel Patel

2. Introduction Early prototype built by Greeks around 250 B.C. First mechanical clocks were massive and made in 14th century. Early alarm clocks were found in Germany in the early 15th century. Alarm clocks became popular in late 1870s.

3. Electrical Engineering Power supply: battery or 120V of AC power from wall socket Generates a 60 Hz signal Screen shows a typical LED seven-segment display

4. Electrical Components Capacitors Resistors Transistors IFT and OSC coil Tuning Capacitor Integrated circuit (IC) chip Loopstick Antenna etc

5. Mechanical Engineering Hard plastic casing Controls located at the top of the clock Antenna for radio located internally Speaker located at top of the clock

6. Industrial Engineering • The alarm clock fits all expected needs, • such as an ability to waking the user, • easy usage, power cord, etc…. • Performance needs are met with cheap • cost, visibility in the dark, reliability, • Durability, etc…. • There are no exciting functions of the • alarm clock to mention. This is a basic • cheap model, with basic functions. • Business prospects show that the clock • would create a positive income and would • be worthwhile producing.

7. Conclusion • The purpose of a clock has been to tell time • There have been many way to tell times over the course of human history. • From Egyptian shadow clocks to Chinese water clocks.From basic to digital • The alarm clock forcefully tells time, and as such its most convenient way, is by our beds.

8. ... • We have been able to deconstruct a simple alarm clock. • In order to think of new way to engineer a better product for the future. • Taking into account: costs, safety, parts, electronics, materials, design and consumer benefit. • There will always be a market for scheduled alarm signals.

9. The Future • The future is always smaller. Compact • Personal use • Future possibilities for the alarm clock lie in touch screen as with popular technology. • A smaller design with easy user access, edit and input. • Rather than a Repeated buzzing as a reminder of the past. We can opt for enjoyable music for a brighter tomorrow.
