Yale researchers have found evidence that a worm species can detect the color blue – even though it doesn’t have eyes, or any kind of visual system that it should, by all accounts, require. In tests, the team found that the color of harmful bacteria in… Continue reading Yale study suggests worms can “see” color even without eyes
Liquid handling workstations are commonly used in drug development, and look like small CNC machines with droppers on the ends which can dispense liquid into any container in a grid array. They are also extraordinarily expensive, as is most specialty …read more
Swiss e-reader maker PocketBook has launched a new device called the InkPad Color that’s reckoned to be the first e-reader to sport the latest 7.8-inch color screen technology from E Ink.Continue ReadingCategory: Mobile Technology, TechnologyTags: E-re… Continue reading PocketBook’s latest e-reader first to use new E Ink color display tech
As a general rule, it’s not nice to prank your mother. Moms have a way of exacting subtle revenge, generally in the form of guilt. That’s not to say it might not be worth the effort, especially when the prank is actually wrapped in a nice gesture, like this ever-changing …read more

The Mandelbrot set is a curious mathematical oddity that, while interesting in its own right, is also a useful tool for benchmarking various types of computers. Its constant computing requirement when zooming in and out on the function, combined with the fact that it can be zoomed indefinitely, means that …read more

If you were tasked with designing a color video monitor, it’s pretty clear how you’d go about it. But what if you’d been asked to do so 20 years ago? Would it have been a cut and dried from an engineering standpoint? Apparently not, as this hybrid LCD-CRT video monitor …read more

3D printed lithophanes are great, if a bit monochromatic. [Thomas Brooks] (with help from [Jason Prius]) changed all that with a tool for creating color lithophanes but there’s a catch: you’ll need a printer capable of creating multi-color prints to do it.
A video (embedded below) begins with an intro …read more

“Never Twice the Same Color” may be an apt pejorative, but supporting analog color TV in the 1950s without abandoning a huge installed base of black-and-white receivers was not an option, and at the end of the day the National Television Standards Committee did an admirable job working within the …read more

When [millerman4487] bought a TCS230-based color sensor, he was expecting a bit more documentation. Since he didn’t get it, he did a little research and some experimentation and wrote it up to help the rest of us.
The TCS3200 uses an 8×8 array of photodiodes. The 64 diodes come in four groups of 16. One group has a blue filter, one has green and the other has a red filter. The final set of diodes has no filter at all. You can select which group of diodes is active at any given time.
Sixteen photodiodes have blue filters, 16 photodiodes …read more
Asteroids is one of the classic games of the early arcade era. Launched in 1979 by Atari, it relied upon using an XY vector monitor to deliver crisp graphics for its space-based gameplay. One of the limitations of the original arcade games was that the game was only rendered in a single colour, white. Over 30 years later, [Arcade Jason] decided to see what it would take to build a color Asteroids machine.
The hack relies on the fact that the original game used a four-bit resistor ladder DAC to draw vectors in different intensity levels. Through some ingeniously simple …read more
