TAD 2010 Day 4: 3 worlds of life, XMOS

[repost]

The display I'm using only has red and green LEDs, but i figured I could do some mixing and add a yellow world without it looking too strange.  Not sure yet.  Also implemented a more 'liquid' mode which looks neat.  XMOS 4-core microcontroller arrived today, went through tutorials, etc.  Planning on writing the scanout driver for the display tomorrow night.

TAD 2010 Day 3: Game of Life With a Twist

20100204-033430

[repost]


Two worlds are overlayed on top of each other - a red one and a green one.  There are also two 'worms'.  When the red worm intersects green life, it transfers it to the red world.  When the green worm intersects red life, it transfers it to the green world.  Life is colored based on the amount of life around it, in its own world.  Not sure how it's going to look on the big display or that I'm happy with it, but it works.

TAD 2010 Day 2: Matrix simulator for Processing

20100202-220509

[repost]

Okay, I got something else done.  I ported my display routines lib (even the rasterizing ones) to processing and made a fake version of the matrix I'm using.  But all the techniques in the library work, as far as color mixing, greyscale levels, bit planes, etc.


Now I can test out the twist on the Game of Life that I'm going for and see how it looks.

TAD 2010 Day 2: Posting the same thing to multiple Posterous sites without redundant syndication

[repost]

I've been trying to cross-post to my own personal Posterous (ledlab.posterous.com) as well as the thing-a-day Posterous, however doing this resulted in syndication everywhere for every site posted to.

Turns out Posterous allows you to specify the service to syndicate to with the email (see the Tips and Tricks section).

Sending a mail to post@yoursite.posterous.com will syndicate everywhere.  posterous@yoursite.posterous.com only shows up on posterous.  Putting these two together, you can cross-post without redundant syndication by simply sending mail to post@yoursite.posterous.com and posterous@thing-a-day.posterous.com.

Thanks to Sachin for getting back to me so quickly on this question.

This may have to do for my TAD as I've had a busy day.
