At May's Maker Faire we met 14-year-old inventor Joey Hudy, and the project that brought him there. Both have become an overnight sensation. Joey's Extreme Marshmallow Launcher, which features a bicycle pump compressor, can launch the spongy confections up to 176 feet. The modifiable cannon barrel can also be used to launch T-shirts.
Joey's project is even more impressive when you hear his life story.

Control your own motor speed with PWM.

AGELESS TECHNOLOGY. Two simple words yet I don't think I've ever put them side by side. In fact isn't this expression an oxymoron? If there is one thing that seems consistent about technology, it's that it ages quite quickly. Engineers, of course, just can't leave good enough alone apparently having never heard the advice, "if it ain't broke, don't fix it." And yet there are a few technology gems in our world that are just as impressive today as they were years ago.
I raise this topic because this month we'll retire an ageless technology. How can you retire a technology that's ageless? Read on and I'll tell you about a technology that is 30 years old, equally as impressive today as it was back then, yet it's being discontinued. Do you think you know?
Continue here and I'll tell you the technology that I'll soon be missing.
