|The Theme You Picked: Back to Analog|
The theme this month is Back to Analog and it comes from kk99 who suggested a competition around devices based on analog electronics. You can create any project that involves analog technology such as an amplifier or you can work on a project that takes you back to the days of analog, such as a simple electronic repair of a piece of analog equipment.
Many technological innovations started out with an analog effort to recreate some type of content or house information. The transition to the digital world we live in now began to stir in the late 70s when people began owning digital watches, and started to taking off in earnest in the 80s. The decade of the 80s witnessed the first cell phone, the first digital camera, the first compact disc, and the personal computer invaded our homes. Perhaps the most visible sign a switch from analog to digital was brewing, came when digital wrist watches, such as the Casio CA53-W1 Calculator Watch from Back to the Future, became a fashion accessory. The wristwatch is also a good way to understand the difference between analog and digital. Analog is closer to the natural world around us, it is represented in waves, whereas digital is represented in discrete signals representing 0s and 1s. Analog design for electronics is more involved than digital and the variables used in analog design are much more interdependent. Whereas digital design involves manipulating discrete inputs and outputs; signals are either on or off, analog design deals with inputs and outputs that are continuous. Analog design is characterized by values between the lowest potential (Vss) and highest potential (Vdd). Digital design is focuses on fewer design specifications such as speed, power, and area of a design in an integrated circuit. In analog design you also need to account for speed, power, and area, but you'll also have to consider things like gain, bandwidth, power supply sensitivity, signal distortion, and several noise sensitivities such as noise figure and phase noise.

Your Project, Your Ideas!
Every month you'll have a new poll where you'll get to decide an upcoming project competition, based on your interests, that will take place a couple of months in advance. Themes are broad in scope so that everyone can participate regardless of skill set.

Step 2: Post in the comments section below to begin a discussion on your idea. Videos, pictures and text are all welcomed forms of submission.
Step 3: Submit a blog post of your progress on your project by the end of the month. You are free to submit as many blog entries as you like until the beginning of the next theme.
Be sure to include video proof of your project!
