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 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.

|Wacky Automation Devices||Vote or Submit Your Ideas!|
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!

Apparently, at one point in history some people thought that eating raw tomatoes was dangerous? That is crazy, because tomatoes are both good for you and absolutely delicious. janisalnis is a fellow tomato enthusiast, and he won the Internet of the Backyard Design Challenge with his automated tomato greenhouse, based on the Texas Instruments SimpleLink Wi-Fi Launchpad. Armed with the knowledge of the ideal temperature for tomato growth, Alnis set up IoT monitoring and control of his greenhouse, with some very tasty results that you can see above along with all the excellent technical detail.

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.”
Geek Pride Day was officially celebrated in the US for the first time in 2008. By 2009, it was officially sanctioned by the Science Channel with special programming. Meanwhile in Canada, events took place in Ottawa, home of the Canada Science and Technology Museum, to commemorate the day.
Geek Pride Day, is a day for everyone around the world to celebrate their nerdom, whether it’s through meet-ups or parties to celebrate anything worthy of geeking-out over.

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.
