Programming Goodies!

About two months ago, I was honored to get to receive a prototype of a “Love to Code” Arduino board that Jie Qi and Chibitronics are currently working on. (If you don’t know how much I love paper circuits and Chibitronics, then read this post before going any further.)

The first thing I had to try was to hack my own disco paper circuit from our Big Book of Makerspace Projects and get my disco dancing on it’s own!

Computational Tinkering

I LOVE how easy it is to map out a circuit and then clip this “Love to Code” board to the circuitry. I decided to try out an RGB LED and do a little computational tinkering to see how different sets of code would effect the blink.

It was so simple to dream up an idea and map it out with copper tape, that I began to get way too complicated in my design ideas. I had a few failures, so I started chatting with other makers about design ideas and brainstorming more ways to use this new technology. Suddenly I had it, I’d seen lots of black out poetry, but what about using lights to “light up” poetry?  I spoke with Josh Burker about tweaking this fun poetry idea and he made a super cool project with lights and poetry.

See Josh’s light up poem here.

Light Up Poetry

I’ve been dreaming up multiple ideas for what I wanted my own light up poetry to look like, and I kept coming back to one of my favorite poems by e.e. cummings: “l(a” I absolutely adore this poem and how the words themselves look like a leaf falling, so I knew I had to make this poem as if the words were animated and portrayed the loneliness of a leaf as it falls to the ground. I wanted each stanza to light up separately and give the viewer some time to think and experience the words as the falling leaf. Initially, I wanted to have the circuit on the clipboard, then have a sheet with the poem and put a semi-transparent gold paper with leaf drawings on top. I made my circuit, practiced drawing leaves, and tested out the light.  Plus, I decided to incorporate my battery holder from sewing circuit club.

When I started testing out my ideas, I found that the words would barely show through when I layered multiple papers. But I still really still only wanted leaves on the top layer and the words to not be visible until the light shined on them. I kept trying different types of paper and printing the poem darker…. it wasn’t working, but I didn’t want to give up on my idea.

I ended up making the poem into an image, flipping it and printing it so that the words were printed in reverse (or mirror image) on the back side of the paper. I mapped out a new circuit and hot-glued together a cardboard frame so the light would be able to diffuse a bit before lighting up each word on the top paper.

My reversal trick worked, but I still wanted to harness the light from those little LEDs. So I made some foil leaves to aid in reflection, poked holes for the LEDs to shine through, and covered the bottom of the foil with scotch tape to insulate my copper tape traces and prevent short circuits. (And I ended up adding more LEDs to the template above)
