This project essentially brings together what I have done separately in different works. It was nice fun to do an all electronics project like a full fledged digital clock or a PCB and also a heavy duty workstation made from wood. But the real fun begins when all that is put into one project. I love both electronics and mechanical engineering and so I wanted make something that portrays the importance of time and also the essence of electronics and mechanical and there came the Electro-Mechanical Clock.
A clock because, as far as I am concerned, time is the most important quantity. This clock contains almost everything – microcontroller, transistor, IC, LED displays, resistors, capacitors, inductors and circuitry done two ways, both as a PCB and also the traditional wired way.
To go with that, there is also a gear assembly and a roller bearing (two gems from the mechanical world) and not to forget the electrical – a transformer and a DC motor.
From gear design to PCB design, this project demanded everything I have. This is just the introduction to the 24 steps it takes to make this. Check it out: http://www.instructables.com/id/The-Electro-Mechanical-Clock/
The time was 8: 10!
