Great idea! reminds me of another project that used IR leds behind a blank canvas in an art gallery. When people go to take a picture of "what junk passes for art these days" the secret "painting" is revealed. This is really cool either way, I was just thinking merging the two would be interresting.
Novel use of a LED array. Nice that Allied provided part numbers for the bits they do supply. But it would be useful if the supplier of the non-allied parts were also part of the article. Especially considering that the LED array is fundamental to the gadget.
You know what would be fun? Hang a weight on a rachet (like a pendulum grandfather clock) to spin a motor/generator to provide the electrical energy for this circuit. Lose the AC mains line cord running up the wall.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
