Gadget Freak: LED Message Board

Rich Quinnell's hand message board uses LEDs to trace out a message in mid air when the hand is waved back and forth.

Nice project

Nicely done, Rich.  I have seen similar message units that use an accelerometer to start and stop the display, but you did the job with a small MSP430 board.  Clever. --Jon

Jon, thanks. The board does have an accelerometer and it is what triggers the display. It was a challenge, though, separating out the gravity signal from the motion signal. Also, I owe a lot to my blogger Ryszard Milewicz, who started this with a program that displayed the I heart MCC message when he waved it around in his hand. I "featureized" it a bit, adding the multiple message capability and adjusting the display timing somewhat. Oh, and it's my hand.

Doing this in two weeks when you don't know C is an amazing accomplishment. Kudos, Rich.

Thanks. Fortunately I didn't have to do it from scratch, and my code would probably make a grown C programmer cry, but I was able to do what I wanted with it.

Very cool.  I'd love to see the next one with a keyboard.  Good job!

Hi Rich, Very clever approach to developing a cool embedded product. The method of modifying code to change the product functional behavior is what I discuss with my ITT Tech Electrical Engineering Tech students every class period. I often use this rapid development method for  embedded devices and gadgets I create in my home lab as well. Very cool project!!!

Cool idea. Maybe the next version should have the board and LEDs affixed to, or embedded in, a glove.  Wearable computing is the Next Big Thing. :)

Some of my code would make a grown C programmer cry too, RichQ. What some folks might call "spaghetti code" I prefer thinking of as "thinking outside of the box" :) Besides, since I am Italian, the moniker fits in my case LOL 

Rather than reinventing the wheel - you simply readjusted it - a great time saver that still took tech know-how - Great job!

I like the idea of the glove. Will have to figure out how to wire it so it won't be scratchy. Thanks for the suggestion.

Very cool idea. I am not sure what purpose it serves, but I like it anyways!
