Rachel and Jim made up some very skinny surface mount LED/resistor strips that fit between Lego posts for a STEM camp Rachel is running.
A simple pattern was etched on flexible copperclad Kapton film, using vinyl from the vinyl cutter as resist. Solder paste blobs and the tiny 0805 components were hand placed, then reflow soldered on the hot plate. Here are some ready to be sliced apart. The resulting glowing Gummi bears were a big hit with the kids!
Campers beta-tested Rachel’s Conducty Inventing Kit during a week-long Spring Break camp at Moore Toys and Gadgets in Wheaton. They built circuits directly on LEGO baseplates using conductive tape and components designed to fit between the LEGO studs. Kids lit up everything from Minecraft torches to outdoor campfires made of LEGO. Here, Cooper and Ella show off their creations. The Conducty LED Inventing Kit will be launching on Kickstarter later this Spring.
We’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 will 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.
