Lab: Breadboards redeux

Friday, September 12th, 2008

Finally got some breadboards and set them up with power regulators and all.

Then got to make some simple circuits. Yay electricity! (more…)

finally here…

today was orientation for ITP…all of us first year students got together to be welcomed by Red Burns and to introduce ourselves to everyone. there are so many really smart, really interesting people in this class, from all backgrounds and from all over the world. it’s quite inspiring to be a part of this community.

after the orientation pockets of folks hung around and got to know each other. we had some brainstorming, including creating a tattoo-based delivery system for generative drawings…it’s about the volunteer trusting the software with creating a permanent mark on them…intense…maybe we’ll prototype with a sharpie marker :) fun

…which doesn’t mean that I understand it. However, it does seem to have the uncanny ability to predict how some things will behave and certainly can make come cool looking stuff.

Expanding on the spirographs from the other day, here’s a modified version which will iterate through a range of .1-10.0 for r and R.

I was messing around with generative drawing for the Processing class I’m teaching…and started playing with spirographs (my bigger brain, ie. Google and Wikipedia, reveals that they are called hypotrochoids).

The algorithms are quite simple:

x = (R - r) * cos(theta) + d * cos((((R-r)/r)*theta));
y = (R - r) * sin(theta) - d * sin((((R-r)/r)*theta));

The results are neat, and mapping the basic variables to keys or the mouse provide a nice way to alter the drawing through iteration. Coupled with the PDF library and some extra code the graphs can be printed out at large sizes. Here are a couple.
