It is also possible to take the idea discussed in Why Keyboards Matter post and tailor it for capacitive touch. This way it also possible to represent 900 individual user inputs with far less microcontroller pins. The main idea behind this…
Making a matrix with 9 inputs isn’t all that bad. I wouldn’t mind wiring each one up. But when we get two orders of magnitude bigger to 900, we want something more cleverly constructed, reducing duplicity and manual labor. While…
Previous blog posts explored capacitive sensing and proposed it as ideal for our digital Peabody quilt. However, unlike a smartphone or tablet, we have a very interesting design problem: how can we embody the quilt form and feel such that…
Peabody project involves making a physical version of Peabody’ alternative timeline representation. The main components will include 30 NeoPixel strips, Arduino Mega microcontroller, and some kind of touch sensors. The project can be subdivided into four parts: crafting the actual…
Two example projects Finding example projects that might influence our design and help us make technical decisions was quite difficult. However, here are two projects that might be useful to refer to: LED Matrix Quilt – using conductive thread, 64 individually-sewn…
The interactions with the Peabody quilt are touch based – the user presses on a square and the LED lights up. Thus, parts of the quilt must be sensitive to touch. There are two potential ways to include touch sensitivity in…
There is extensive documentation on NeoPixels, including a very handy “überguide”. It is written assuming experience with Arduino/electronics. I would recommend following this, and using this post for clarifications. While I’ve had a reasonable amount of experience, I would still…

When purchasing materials for the Peabody visualization quilt, we discovered that LEDs are expensive, and budget might be a limiting factor. Subsequently, we constructed our quilt’s physical design around this constraint. To light up our quilt, we purchased strips of digitally-addressable…
In our physical touch-interface version of Elizabeth Peabody’s work, we are going to use a controller separate from the quilt for the purpose of selecting a color/country to begin. We do not yet know what exact form the color picker…
