RGB LED's Now Consumer Grade - Hackable?

[jstjohnz]

Out of curiosity, which specific item in Ray Wu's store are the "improved seal" strings?

I'm thinking of ordering some.

The item description never changes, he seems to just ship whatever he can get his hands on. The last ones have RED-WHT-GRN-BLUE colored wires.

The other thing you need to watch for is distance between pixels, be sure to let him know if that's critical for you. Tell him you want ones like the last batch of 16 he shipped me, and mention the color code.

Not specifically re the GE strings, but attached are a couple of pics of my pixel matrix 50x32, not the GE pixels, but shows what kind of effects you can get with a big pixel matrix. This is showing some of the misc color effects produced by the Madrix software. These were taken in a hurry and I was off to one side rather than facing the display head on. The matrix is about 10 feet wide by 12 feet tall.

For those using an Arduino as a controller, I think I've solved the timing issues by using the more precise delay functions in the delay_x library available at http://www.avrfreaks.net/index.php?m...m_type=project (registration required). The _delay_us() function should give you the more precise timing required.

If there's interest, I can clean up and post my Arduino code.

lots of interest

Okay, here's what I've put together. It's my first Arduino sketch ever, and I haven't been able to test it with an actual set of lights yet, but I think it should work. I overloaded the functions to make creating sequences a bit simpler; otherwise I think it's pretty straightforward.

If anyone has any corrections, improvements or suggestions, please let me know.

Check out the work Andy Coulson has done:

It is quite cool.

Also, austinlightsguy has done some amazing work on this over at http://austinlightguy.wordpress.com/...light-strings/

Edit - Should have refreshed the page before posting...

okay so just tested this and well.... i get a massive amount of random colors. some bulbs seem to be changing colors like u intended to do but the bulbs that arnt changing are random shades and intensities. it also still sees it as a 36 string when i have changed everything i could think of to make it a 50 string

i also changed the commands in scott's code to use the _delay_us() it didnt do anything different that i noticed

Got my Arduino uno today and some parts. Now what to do with it?

Also got a small breadboard, I'm hoping this will allow with the pickit2 to program some PICS for another need.

Now who is grabbing me by the hand?
