Could be a fun Christmas gift

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!).

This looks like a fun thing to come up with and to do. And the images or words can always be changed when you get tired of them.

This looks like fun.  Great idea for waiting rooms.

NadineJ, I agree. Nice way to pass time while waiting for an appointment. If sensors are included the artwork can be interactive and visually appealing.

Harvest some energy

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.

I like that idea, yes agree power cord is not ideal for this kind of application. The other option here would be battery power.

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.

oops, somehow that got missed, here's the link to the LED matrix, the project uses two of these guys https://www.adafruit.com/products/555

Thanks.  Would make a great scrolling sign that shows what FM channel I use for the music I play with my blinking Christmas lights.

The RGB modules look really nice too.  Wish I had the time.

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.

Hey John, the secret painting is a great idea. This current project doesn't have an IR sensor and RGB LEDs but here's another project . I will try the secret painting effect for sure on that one.

John,, This project is appropriate for scrolling messages. Adding color mixing via RGB LEDs adds another level of aesthetics for this project.

Al, Very cool project! In reviewing the Build Instructions, quite a bit of assembly mastery. How long did it take for the project build?

Hey mrdone, the build was pretty quick, took about 3 hours.

Al, That's pretty awesome. What was the motivation behind doing the project? Do you have a circuit schematic diagram for the project to post?.

Hey Al, Mrdon has a good question here. Do you have a schmatic to go along with the gadget?

Great gadget! Just wonderful. I don't know if I could do it but I might try building one. Looks a little intimidating.

  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.

Neat project, but I had some of the same questions as you did.
