|Back to Analog||Vote or Submit Your Ideas!|
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.

|Test Instrumentation||Vote or Submit Ideas!|
The theme this month is familiar to anyone that participated in the DIY Test Equipment contest last year, Test Instrumentation is a repackaging of the same concept but we've added a twist to make things a little different. You can post the same type of projects as before but if you have an idea that involves a creative use of a micro:bit we'll ship you one (while supplies last). Also, different from last time is we're offering Tool Sets as prizes courtesy of Klein Tools. You can also win a Grand Prize of an 18 pc ($327 value) Journeyman Tool Set along with a $100 Shopping Cart for the most original project. In addition, the Three First Place Winners can win a 6-Piece Trim Out Tool Set in addition to the usual $100 Shopping Cart. You are free to use any components you like.
If you know anything about our members, its that they love their hand tools and test instrumentation. This contest allows you to build your own test instrumentation using whatever components you like. If you're just getting started with electronics, Test instrumentation will help further your understanding of how electronics work, giving you a chance to get your hands dirty with microcontrollers, development boards, tinkering, and soldering. If you're looking for an easy way to get started on electronics, you can propose an idea that uses a micro:bit and we'll send you one (while supplies last). If you're more experienced, you probably have as piece of favorite test equipment on your bench that you could never live without. You've also probably run into situations where you need a custom Test Instrumentation device, that you can do yourself, that not only fits your needs, but can be done at a fraction of the cost. If you have an idea that involves a micro:bit wearable as part of your test equipment comment below and we'll send you one for free (while supplies last).

"A man who is certain he is right is almost sure to be wrong" - Michael Faraday, father of the electrical motor
"Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more." - Nikola Tesla, father of the first AC motor
The theme this month comes from beacon_dave and its Movers and Shakers. Its any project that causes things to move or shake such as ones that use servo motors, stepper motors, vibration motors, solenoids, mechatronics, levers, and linkages.
The idea was first proposed by a servo project competition was first proposed by beacon_dave in response to Building a Hobby Servo Controller – Part 1 by shabaz before expanded on in the monthly poll: https://www.element14.com/community/polls/2705#comment-125810.
The Movers and Shakers theme is in honor of the contributions of movers and shakers in the scientific community such as Michael Faraday and Nikola Tesla, and to anyone that moves progress forward by forcing change.
Faraday was responsible for some of the scientific achievements rank up there with the great ones such as Einstein, Newton, Maxwell, Hawking, Ampere, Oersted, Hertz, Edison, Volta, Tesla, and Edison. Einstein kept photos of 3 scientists in his office: Isaac Newton, James Clerk Maxwell, and Michael Faraday. Thomas Edison, Nikolas Tesla, and Michael Faraday are all considered the fathers of electricity. Faraday himself would meet fellow Movers and Shakers, Ampere and Volta in Milan.
Another reason that Faraday is featured in the Movers & Shakers theme is because his discovery of electromagnetic motion would lead to the electric motor. His project was an electric motor apparatus and its the oldest is surviving Faraday project dating back to 1822. He used a mercury bath to transform electrical energy into mechanical energy in what could be considered the first electric motor

The Theme this month is smart alarm clocks and it comes from dwinhold .
Its to build an alarm clock with modern features such as voice assistance, streaming music, video, camera, an SBC, weather alerts, news alerts, moon phases, appointments from your phone, oled or LED screen.
You can credit an engineer, around the year 725, with one of the earliest recorded records of a device used as an alarm clock. Yi Xing was an engineer, mathematician, Buddhist monk, and astronomer whose task was to improve calendars in China.
He took it a step further by building an astronomical clock named the “Water-Driven Spherical Bird’s-Eye-View Map of the Heaven. It not only measured time, it measured the distance of planets and stars. A water wheel turned the gears on the clock and it released puppet shows and gongs at set times.

"The discovery of song and the creation of musical instruments both owed their origin to a human impulse which lies much deeper than conscious intention: the need for rhythm in life… the need is a deep one, transcending thought, and disregarded at our peril." - Richard Baker
"I have my own particular sorrows, loves, delights; and you have yours. But sorrow, gladness, yearning, hope, love, belong to all of us, in all times and in all places. Music is the only means whereby we feel these emotions in their universality." - H.A. Overstreet
“Music is an art that expresses the inexpressible. It rises far above what words can mean or the intelligence define. Its domain is the imponderable and impalpable land of the unconscious.” - Charles Munch
The theme for this month is Simple Music Maker and it comes from DAB . Music is something close to many people's hearts, including yours truly. Use whatever electronic components you like to create a device that plays music. It can be an instrument or an electronic device that plays music.
You can create any electronics device for musical instrumentation using electronic components such as a Raspberry Pi, a Beagleboard, Arduino, stepper motors, microphones, light sensors, speakers, and more. Or you can create a device for the consumption of music using electronics components.

|Robots with Wheels||Vote or Submit Your Ideas!|
The theme this month is Robots with Wheels and the idea comes from koudelad. Several members such as ninjatrent , rpbruiser , and .jomoenginer also expressed interest in doing a competition around robotics so this should get plenty of you excited.
A robot with wheels is different from a car, because it has not only a moveable body, it has a computer to act as a "brain" for the rest of the system. In order to move its body, the robot requires an actuator. Examples of actuators a robot can use are electric motors (such as a DC motor) and solenoids.
A robot can use all types of actuators but the actuators will have to be driven by a source of power, such as a battery pack. Actuators are wired to an electrical circuit and this powers electrical motors and solenoids directly. The "brains" of the robot is the computer and it controls everything attached to the circuit. To make the robot move, the computer switches on all the necessary motors and valves.
Sensors found in robots include photoresistors used for light or as a proximity sensor, microphones used for sound, temperature sensors, contact sensors, infrared transceivers, accelerometers, gyroscopes, and voltage sensors. The term robot comes from the Czech word robota, generally translated to "forced labor". You can create a simple wheeled robot using a microcontroller such as an Arduino, servos, breadboard, wheels, sensors, a battery pack, and programming.

|Cool LED Display||Vote or Submit Your Ideas!|
This month's theme is Cool LED Display and comes from dougw. Anything goes with this, you can use LEDs individually to create a display or come up with a creative way to utilize an existing LED display. An LED display build makes a great weekend project. For example, you can take a cheap microcontroller such as an Arduino, some LED pixels, some everyday items, and something you picked up from Ikea for your project. Or you can make a monochrome display, something with holiday spirit, an LED Cube, make an LED calculator, or do your own special lighting effects.
The only LEDs that were around for the first 10 years they were around were red visible light. Ten years later there was Green LED. In 1994, there was blue LED. You can get blue or green LED through a mixture of Gallium Nitride and Indium Nitride to get the blue, called Indium Gallium Nitride (INGaN).
Varying the amount of Indium in the mix varies the color of blue. Red, orange, and yellow LEDs use variants of Gallium Phosphide (GaP) Gallium Arsenide Phosphide (GaAsP) to get their hues. With white LEDs a blue or violet LED is coated with a phosphor that emits photons from the ultraviolet frequencies when the LED is energized.

The holidays mean something different to everyone. Think about what makes the holidays special to you and do a project around it. Use your imagination to build something that could only come from you!
If you want to relive the glory days of 1978, or what you imagined life was like living in the late 70s go for it. You could make your own obscure late 70s movie prop complete with lasers, sound effects, and as kitchy as you want it to be.
Or, You can simply make a fun project in the holiday spirit whether that's making a snow globe that will warn you of inclement weather conditions, voice-activated ornaments, jazzed up holiday cards, LED decorations - anything that means the holidays to you.
If you don't have a tradition you celebrate, don't want to celebrate the one you grew up in, do a project that is authentic to how the holidays really make you feel. You can even look at other traditions or time periods for inspiration and learn something new in the process. It can even be a Star Wars project, if you only believe in the Force.

The idea for Simple Electronic Repairs comes from fvan . His idea is to repair a device that is malfunctioning instead of throwing it away or buying a replacement. Simple electronic repairs is good first step before tackling a full blown electronic projects on your own. This is a good opportunity to start tinkering with an electronic gadget you love but might be missing because its no longer working.
As fvan points out, simple electronic repairs doesn't need to be complicated, such as repairing a faulty switch and will give you insights into some troubleshooting techniques. He uses a malfunctioning Xbox guitar (pictured right) as an example. One of the buttons would only allow you to go up instead of up or down, seriously limiting your options of what you could rock to. Rather then throwing the guitar away and getting a new one he opened it up to discover a reed switch was used for each position. One of these switches was constantly "ON", even in idle position, due to the magnet and switch being too close to each other. By gently bending the legs of the reed switch a little further away, it created enough distance to move set it as "OFF" in the idle position.

The idea for Wacky Automation Devices comes from dougw. This theme let's you come up with an automation device similar to a Rube Goldberg machine. A Rube Goldberg machine is a complex contraption in which a series of devices perform simple tasks and are linked together to produce a domino effect whereby activation of one device triggers the next device in the sequence.
You've probably witnessed the influence of Rube Goldberg in cartoons, movies or TV shows you've watched. Depictions of overly engineered contraptions leading to intense chain reactions resulting in simple results can be seen in movies such as the Goonies, Beauty and the Beast, Pee-Wee's Playhouse, and Ernest Goes to Jail.

The Idea for the Solar Powered Gadgets comes from dougw. The focus of the theme is on using solar power to create gadgets for the yard. Wouldn't the world be better place with more yard gadgets that harness the sun, a seemingly inexhaustible (billions of years) source of energy?
Among the many benefits of using solar power is the fact that it saves money while providing energy reliability, energy security, and energy independence. The sun doesn't shine 24/7 but that's hardly a drawback. In theory, with proper storage, you could theoretically use solar power to provide for all of the world's electricity needs. Solar easily dwarfs all potential energy sources combined and an electronics project that makes use of it, is well awesome!

On May 25th, 1977, Star Wars Episode IV: A New Hope was released and the galaxy will never been the same. In solidarity, followers greet one another with “May the fourth be with you.” Those on the dark side argue whether May 5th or May 6th is an appropriate day to celebrate their “Revenge of Sith Day.” May 25th is also a date celebrated by followers of Douglas Adam’s Hitchhiker’s Guide to the Galaxy, that's the date they celebrate “Towel Day.”

Toys can be objects of solitary attention or centerpieces of social interaction. In keeping with the world around them, toys are becoming more electronic and are increasingly used for interactive digital entertainment.
Toys aren't just for children of course. Many adults are avid toy collectors for monetary as well as emotional reasons. A toy may conjure sweet childhood memories, quench a longing for a simpler time when life was a lot easier, and bring back a joy that may otherwise have been forgotten as the world forces you to live by the rules and responsibilities of adults. Some adults never stop playing with their toys, you can see this for yourself by going to a Lego convention.
