Minecraft Extravaganza

IMG_20151023_002406We’ve mapped out a wiring diagram and rough layout for an Arduino-controlled Minecraft landscape. Bill has graciously agreed to write the code. Rachel roped in a bunch of newcomers to build part of the set and brainstorm Minecraft “events.”

We settled on a line of light-up Redstone dust (red LEDs in perforated boxes) leading up to a tree which catches on fire (LEGO flames IMG_20151023_012142657will stick out of the tree). Then a second tree will catch on fire. We’ll be working on it at Workshop 88 the next couple of Thursday evenings if you’d like to stop by and contribute your Minecraft, LEGO, and/or Arduino expertise.  Come play!

We’re gearing up to display this at the Barnes & Noble Mini Maker Faire, along with some other projects.  Scott Wojton from the Naperville store has been out to the space a couple of times and has been very helpful to us,so we’re happy to be showing stuff at his Faire Nov 6-8.

At Southland Mini Maker Faire

W88Table3412Workshop 88 had a table at the Southland Mini Maker Faire in Mokena on 8/22/15.  Jim’s drawbot string plotter made a “big” hit, standing 6 feet above the table and drawing poster-size images.

The drawbot, a junkbox project inspired by Bill Paulson, is driven by a couple of $3 steppers from American Science and Surplus, some cheap H bridges and an Arduino clone.  Software is free from Makelangelo.com.  It does the heavy lifting math to convert from X-Y coordinates to the “inches of string” coordinates the polar geometry imposes on its steppers.  In addition to accepting normal X-Y gcode, it can take a jpeg image and use the traveling salesman algorithm to generate a single path reflecting the darkness of different areas in the image as it’s doing in the picture above.  Such a path is ideal for a plotter that doesn’t have pen lift capability.  Yet.
