LEDGrid: Playing with touch

Posted on February 16, 2016 by Erica

Branden has been working hard in the past few weeks to finish the LED grid assembly. All of the boards are together now, and things are (mostly) working. Here’s a quick video of the board in action, and connected to Processing on the laptop. (Sorry for the whiny cat in the background. Yes, she is…

VizTech2: Beautiful Particles

Posted on February 12, 2016April 12, 2019 by Erica

I mentioned in my last post about VizTech2 (my P5.js course, with Pedro Cruz) that we had learned how to make a fireworks display using particle systems. At first, the sketch made fireworks when you clicked with the mouse. Then, we taught it to generate new fireworks by implementing a “lifetime” for each particle. If too…

LED Grid: Hardware development

Posted on September 2, 2015April 12, 2019 by Erica

This is a guest post by Branden Gunn, about building the LED Grid for our collaborative design project The hardware for the LED grid project consists of two major elements: The LED lights, and the IR touch system. The first idea for the board had the main LEDs spaced out in a 10mm grid. I…

GLP bucket app

Posted on August 18, 2015April 12, 2019 by Erica

I wanted to wait for permission from Jonathan before posting about this project, and between one thing and another, I am hitting “publish” on this post in December, even though it was written in August… So, I had this crazy idea the other day. (So far, nothing news worthy there…) It all started when Jonathan…

LED Grid: Blinking lights!

Posted on August 12, 2015April 12, 2019 by Erica

This week and last, we’ve been working hard to set a budget and optimize the design for the physical object side of the LED grid project. Branden has been developing a list of parts and is starting to lay out the circuit board design (maybe I’ll convince him to do a guest post for that part?). In the…

LED Grid: working toward a design

Posted on August 5, 2015April 12, 2019 by Erica

I wrote about the origins of my LED project and my first tottering steps toward programming in a previous post. Here, I’d like to talk a bit more about the design part of this project. (That’s way more fun, anyway.) For an electronics project like this, there are two aspects to the design: first, what does the…

LED Grid: To learn a programming language

Posted on August 5, 2015April 12, 2019 by Erica

I stumbled into the design world kind of by accident back in March or April. A flyer mysteriously showed up in my mailbox advertising a seminar on presenting data by Edward Tufte, to be held in April in Boston. It turned out that I had a schedule conflict and couldn’t make the seminar, but it…
