Programmers Gone Wild

Mark Hall demonstrates what happens when you give him a project and time to play. Exciting stuff! I hope this becomes the centerpiece of our lighting artwork this year.

Hey Ulan,

Yeeeeeaaaaaah, booooooy!!!

Wanted to share my progress with you. I’ve got a library that is capable of:
* Setting each pixel group (pGroup = 3 lights -> one chip) with a unique given color
* Setting up a strip with a pattern by filling (A, B, C, A, B, C)
* Setting up a strip with a pattern by fitting (A, A, B, B, C, C)
* Sending a pattern of color down the strip
* Sending a pattern down the strip that dims whatever is already on the strip

All these features are being used in the attached movie…
* Strip test – The strip is filled with white, then red, then green, then blue, then white. Tests each individual color of each pixel on the strip to locate “bad” ones
* Three chasers are sent down the strip with one yellow and one green pGroup
* Three chasers are sent down the strip with a dimming pattern (100%, 75, 50, 25, 0, 0, 0, 20, 40, 60, 80, 100 – This pattern dims faster then it un-dims) .
* The two groups of three chasers are stacked on top of each other
* When the chaser is done with a pGroup it sets it back to the background pattern
* In the first run the background pattern is filled. The second uses fit

So, I looked carefully at the Vimeo video of the lobata. I created all these software capabilities so that I could simulate one particular pattern I saw them do. They have a series of colors and they go down the line closing up the “thingy” (forgot the name), so the light is refracted and then dims to “off” and then back “on”…

There are other pulsing/flashing things it does… I am not far off from making those things happen. There are also a few programs from the controller you’ve been using… I can also make those now by using what I have built. The top level pulsing red that you talked about last year… I can do that, too.

So, when will y’all be down at Unaverz, so I can demonstrate this in person and get your feedback?

All the best,
