Welcome to Time Machines, where we offer up a selection of mechanical oddities, milestone gadgets and unique inventions to test out your tech-history skills.

Today the world can easily be captured in 1s and 0s for our viewing pleasure. The hardware behind this capability all started as a DIY lab project in 1974 to test out some new gear, and the result was a Frankenstein-like device that would eventually lead to world-changing advances in photographic technology. Head on past the break for the full story.

Panasonic shows micro color splitters that double up image sensor acuity

Panasonic shows image sensor that splits color to double up on sensitivity

Panasonic has developed a new type of imaging sensor that gets more photons where they need to be by foregoing the use of conventional CMOS debayering filters. Those can reduce sensor effectiveness by blocking 50 to 70 percent of the light, so researchers developed "micro color splitters" to do the job instead, which can separate hues microscopically using refraction. They did it by taking advantage of wave optic principals to create a new type of electronic "deflector" that can analyze and separate light wave frequencies much faster than previous methods. There's almost no loss of light during the process, and such devices can be made using conventional semiconductor fabricating techniques, too. There's no timetable for commercializing the tech, but Panasonic holds 21 domestic and 16 overseas patents on it -- meaning it's likely not just a science project.

The mysteries of the CCD revealed (video)

The Mysteries of the CCD revealed

Sure, we've explained to you why sensor size matters in a digital camera, but maybe you need to take it back a bit. Maybe, you're not entirely sure how those sensors work in the first place. Well, Bill Hammack, better known as The Engineer Guy, is here to help. After breaking down LCDs and hard drives for your amusement and education, Bill has turned his attention to the CCD. The charge-coupled device is the heart and soul of many a digital camera, turning incoming photons into a charge that the impressively complex processor inside can convert into an image. What makes the CCD so impressive is it's rather ingenious solutions to problems such as interference (no wires, just a shift register) and color reproduction (pixel-sized filters and a hue-flattening algorithm). For more, check out the video after the break.

Sharp readying 1/2.3-inch, 20.2-megapixel CCD destined for noisy point-and-shoots

Sharp readying 1/2.3-inch, 20.2-megapixel CCD destined for noisy point-and-shoots

As you probably know, megapixels aren't everything. In fact, the more of them you cram into a smaller space, the noisier your images will be. So, you'll forgive us if we don't exactly shout from the mountain tops that Sharp has managed to stick a whopping 20.2 megapixels into a CCD only 1/2.3 inches in size. That does, however, give the RJ23G3BA0LT the highest pixel count in that size range. That's gotta count for something, right?
