Make a Video from a Processing Sketch

I needed to do this and found the steps challenging enough I wanted to keep them here, and maybe they will be helpful to others. I needed to take the words in a static wordle-type presentation and animate them, so they move around a bit. Then I needed to add that animation to a video of a dance.

OpenSimulator In the Classroom Through the Years

I haven't run any sim projects for a while and I miss it. I just found a cache of pictures of sim projects and am amazed at how far it's come. Here are some of the pictures to give an idea of the territory students and I covered together. What an adventure!
Our first sim! With a spare assortment of prims students acted out skits for
their drama class.

ShapeTiler App with WaterColorBot

I updated my Shape Tiler program,
made with Processing.js,
to be a standalone version that exports a PDF of your shape tile, which you can then import to Inkscape and send to your WaterColorBot to draw. Why make a plotter draw your shape tile design rather than just printing out the png from the online version? I don't know! But it's fun to watch.

Getting Oriented With Minecraft Pi

Minecraft Pi is Python for Minecraft. You can run Python programs from a folder on your computer that make things happen in a Minecraft server in the same computer or even on a remote one. Actually Minecraft Pi is for the Raspberry Pi but I'm using the MCPI mod which can work on a regular (vanilla) Minecraft server or I have it working on a MinecraftEdu server (version 1.7.10).

Sharing the LogoTurtle at World Maker Faire

  • A 10 year-old boy who had never programmed in Logo saw the square example and immediately saw how he could modify it to make different shapes and nest that loop in another loop to make the multiple tiled shapes on the left. His dad was floored by what he did so quickly on his own. He left with his family for a while and came back a couple hours later and added to his octagon program to make the shape in the video. Amazing, he had been thinking about it while walking around and wanted to pursue his other ideas about it.

More VR Explorations, Now in HTML

I just learned about Mozilla's A-Frame framework for VR development. Wired touts it as an easier solution to the heavy lifting required by the Unity environment. The main thing this get rid of are the iOS or Android platform requirements of setting up a Unity environment.

Learning From the LogoTurtle

Teaching with the LogoTurtle was an experiment for me last spring. I knew there would be a lot for my high school robotics students to learn from it but I didn't exactly know what. At the end of our LogoTurtle unit I asked the students to write about what they felt like they learned. I didn't prompt them to write about any specific aspect of their learning, I just wanted to see what would come out. I've been thinking about what they wrote and realized a few things; 1) each student is on her own learning adventure, 2) the LogoTurtle is actually teaching them as much as, and maybe more than, I am, and 3) what are often called the soft skills of learning-resilience, collaboration, making mistakes, perseverance-were a significant part of the experience for them.

Finally Figured Out How to Write a Class for Python Turtles

This explanation/examples did it. Exercise 4.2. Here is what I ended up with.

Updating Firmware on the Gogo Board V4

I have a bunch of Gogo Boards I've used for 4 years to teach creative making with robotics. Problem is mine are version 4.x and the developer, Arnan (Roger) Sipitakiat, has fully moved on to version 5.x. But there is a version 4.x setup that keeps my older boards working with Arnan's awesome blocks coding website, I'm writing this post to keep track of the pretty serious yak shaving necessary to keep them functional, probably only useful for my future fixes as only a small (Trump sized) handful of people ever used these boards. The Gogo Widget doesn't work to update the firmware on these older boards on a Mac, so I have to remove the Microchip PICs to reprogram the firmware. I have a Cana Kit UK1300 PIC programmer. But the software for writing the hex file to the PIC, PICkit 2, is PC only, so this tool is needed to write to the PICs on Mac. However, part of the instructions, adding two files to the root bin folder,
