It's always interesting to me what clever engineering types can come up with just for the sheer pleasure of it. This is definitely something fun for people who want to personalize their wall decor. While it won't turn anyone into a Picasso, it's certainly worthwhile for entertainment purposes. It reminds me a bit of those digital picture frames, and like those I think it could make a cool Christmas gift (if it was on the market and affordable, of course!).
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.
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.
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.
This thing is way above my pay grade, so if the questions are foolish, I apologize.
How many charactors can this device store? Must they always be displayed in the same order or can you automatically change messages? Do the LED's damage the parent painting? Could you set other displays and shuffle between using the same controller.
Some earlier post mentioned waiting rooms and I am just trying to figure how many times I would be willing to read it before I scream and want to tear it down.
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
