Now Cubey can be controlled using using TouchOSC on iPhone / iPod Touch (TouchOSC is also available on Android so this should probably work on that too).
Cut along the solid lines, fold along the dotted lines. The ears and the gold ring things are meant to be folded back on themselves so that they’re colored on both sides (I’m seeing a lot of people who don’t get this! It’s somewhat important!). See the images in the gallery if you’re confused. I didn’t add the tail to mine because I didn’t glue the back closed, but basically cut along the solid line on the tab on the back part of the main body and insert the tab from the tail. If you make one of these, post it here, I’d like to see it!
I also added electronics to it (I am terrible at soldering; you have permission to laugh at the pictures of the circuit)! One servo for rotation of the entire papercraft, another servo and a rubber band for moving the ears up and down, and two photocells (one on each side) to sense light. I have it so that Cubey will turn either toward or away from light depending on what I set in the program. I tried adding remote control, but my IR receiver kinda broke somehow. Here are some videos of the other stuff, though.
And more on the channel. Image gallery in the full post.
I modified the scrolling text program some more, and was able to get it to display text based on received serial input. Then I wrote a Python script to get random entries from various RSS feeds (In the video above, the RSS feeds were the Twitter favorites of various people) and send them to a serial port (to be received by the Arduino). One issue was that sometimes the text was too long for the Arduino’s 128-byte serial buffer, so it would get cut off at the end. To resolve this, in the Python script, I split the text into multiple parts and had it wait for the Arduino to request the next part before sending it.
The Arduino code works on its own; you can use the serial monitor in the Arduino compiler to send text to it, but if it’s more than 128 characters, it’ll get cut off. Just remember to have it add a newline character to the end of your input. Also, removing the lines that say “Serial.write(GET_NEW);” and “Serial.write(GET_MORE);” would be a good idea, if you don’t plan on using an external program to provide the input.
(Edit: I’ve updated the code so that it doesn’t spam the serial monitor if you don’t input any text. Also the python code has many flaws and sometimes it crashes, whoops)

Got a green LoL shield using part of the $80 I won from SparkFun’s Free Day (The rest was used on an Ethernet shield, a solder vacuum, another touchscreen breakout board, and breakaway female headers).
Soldering it took forever (three hours) because I am terrible at soldering. In the end, things weren’t soldered so well so some of the LEDs weren’t lighting up (two of the columns didn’t light up because of a single badly-done solder joint), so I had to do a lot of checking. I also burned out one of the LEDs; thankfully they included 8 extra LEDs, probably for such things. The solder vacuum helped a lot more than I thought it would; it’s way better than the desoldering bulb I was using.
I edited the touchscreen Neko program to include Marisa sprites based on her sprites from “Patchcon: Defend the Library!”, except in monochrome. She can also be controlled by serial port if connected through USB: send a header byte of 255 to the Arduino, followed by the X and Y coordinates, and she will move there (assuming the previous command was a valid one). This allows her to also be controlled by, say, Ustream/IRC chat commands.
Source code and bitmaps can be found here.
Update: Had an interactive stream on Ustream where viewers could type “!mari” followed by two integers, and she would move to the coordinate (unless it’s too large or small, then she moves to wherever she can). Here‘s a recording of the stream; cooler stuff happens at about 13 mins onward (fire and snow effects). It doesn’t record the chat messages though, but they were definitely there.
