How To: Clean a Flag

We hang flags to proclaim our patriotic spirit. This is especially true for retired veterans or those who have loved ones serving in the military. Others hang flags representing the seasons, important events, favorite teams or just a cute and whimsical design as decoration. An American flag can be particularly tricky to wash. Red, white and blue all lying together in one inseparable panel can cause the blue or red dye to bleed onto the white. This is not just a problem with an American flag; ...

How To: Make Surface-Mount Electronics at Home for Smaller, Cheaper DIY Gadgets

Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.

News: Finally! A Practical Use for Arcade Game Skills

Most kids who play video games will never become professional gamers. Those that do are part of a very select group— it's like being a professional actor or athlete. It's nice work if you can get it.

If you have confidence in that prophecy, you're probably not even reading this because you're too busy either A) preparing for the Rapture or B) sitting in your backyard bunker hoping to outwit annihilationism.

News: Carnivorous Furniture Eats Flies and Mice for Energy

PETA wouldn't consider James Auger and Jimmy Loizeau's ingenious flypaper clock very eco-friendly, but I might beg to differ. The clock doesn't require any electricity or batteries. Instead it captures flies and converts the bodies of the dead insects into energy. Eight dead flies makes for roughly twelve days of power. Not bad.

How To: Create a PCB Etchant That Automatically Improves After Each Use

Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.
