Particles in Processing

Posted by Erin, the RobotGrrl on Wednesday, November 5th, 2008

I finally finished off the “Define Dancing” Processing artwork that I started a long time ago! The reason why I didn’t finish it back then was because the colours were messed up. I figured them out, and while playing with the colours, I created another program called Particle Finger Painting
Here’s the Define Dancing one…

You can move your mouse around, and one particles will stay with it. All of the other particles are attracted to it, but some are stronger than the others. Plus, there’s forces between all of the particles too - some of them are negative, which results in “fireworks”-like collisions
Here’s the Particle Finger Painting one-

I really like this one… it’s the same as the Define Dancing one, but the layering and transperency of the ellipses are different.

They both use the traer physics library for the particles.
Try the live ones out- they’re probably laggy since it’s in a browser. In that case, you should download Processing and try them out. It’s a good IDE to have anyway!

Where Am I?

Posted by Erin, the RobotGrrl on Monday, April 21st, 2008

Why were there no blog posts for a week? EEEEEK!

I was studying….working…programming! ^^

I’ll skip the terribly boring stuff and get to the point(s)
- Tuesday, Wednesday, Thursday - track practice
- Spent Friday in Ottawa ^^
- Half of Saturday I soldered stuff
- Sunday I programmed in a GUI & went biking in mud with a friend
- Monday I am watching the Habs Homework I’ll do after
There was an extremely good day at school last week… we get to make a Rube Goldberg machine for Physics!! This is SO cool it’s unbelievable to have this opportunity. I’m still in awe, and verrry excited to start working with the wood with our team! Sure… our team may go overboard for a simple simple machine combination contraption … but when will the chance of building a Rube Goldberg machine come around again?
What I am working on now is getting my LCD to display a custom screen that I drew out on paper. What the problem appears to be is that it can’t handle many characters… I have 3 custom characters… I FINALLY got the 3rd line to work, so now I have to figure out the 4th line. It’s really annoying. I’ll figure out, somehow, how to cut down the amount of info/characters that has to be displayed.

Additionally, I’m working on making a SQLite database interface for conversation links and language models. Once I get it working, I’ll be linking it up with Robbie. You can then imagine all the possibilities with regards to the different language models that will be downloadable! I’m thinking a gigantor mental math mini-game one…
My fingers on my right hand are insane… thumb- raw’ish from soldering. index- has something wrong with it as I can’t lift it middle- a chunk of skin is missing because I unplugged my magsafe the wrong way… ring- my grad ring is ALWAYS falling off pinky- sprained a bit, from … I have no clue
That’s all for now. I like how next year’s FIRST robotics is going to be completely different, with the new WPI programmer software and all! 802.11n will be great for ANNs too. I hope I am lucky enough to take part in FIRST next year!

Robbie is Better than Ever!

Posted by Erin, the RobotGrrl on Sunday, March 9th, 2008

Woooohoooooo!

So, the whole purpose of the 20-inch display being lent to me was to display a bigger Robbie. Check out the pics, he looks AWESOME! I just want to poke his chubby-wubby cheeks ^___^. Frankenteddy: Erin, Robbie doesn’t have chubby cheeks. Erin: Shhhh! x]]

I ran into some roadblocks today *coughtyposcough*, but thanks to scott he helped point them out to me! (THANKS!!!)

It all seems reasonably accomplishable now! I have to add in more levels to the conversation though, but I’ll probably put the app up for download tomorrow morning, after I make the survey form.

7 sleeps till science fair!

Arduino LED Testing

Posted by Erin, the RobotGrrl on Saturday, November 3rd, 2007

I received my Arduino starter kit from ladyada.com not too long ago - Oct. 30th to be exact - It’s AWESOME! I really think this will work well. Check out the pics and video below!

This is the Arduino Deicemilia board - the main thing.

The Arduino hooked up with a servo - I was testing it. Works well!

This is the protosheild. It sheilds the Arduino for you, this way nothing should happen to it! It is also easier to create circuits with. I spent an hour or so today soldering it all together (I learned how to solder, YAY!)

And now for the test video!

Hope you like!
As for the programming of the project, it is not going too well. I will have to devise a new plan ASAP. I believe I have to submit the project near the end of December… YIKES! However, I am sure I will get it done!

I have registered for MIT ESP’s Splash 2007, mainly in Computer Science classes. It’s going to be the best weekend EVERR! I really can’t wait. Hopefully they can help out once I tell them about the project.

Adios amigos!
