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…

LED Grid: First hardware tests
This is a guest post by Branden Gunn, about building the LED Grid for our collaborative design project. In the last post, the boards had just arrived, and the rest of the parts were on order. A few days later, everything was here! Because resistors are so cheap when you get 100 or 500, it…
LED Grid: Hardware development
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…
LED Grid: Blinking lights!
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
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
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…
