Scratch Your Itch for 3D Modeling with BeetleBlocks

If you want to create a 3D model, you’ll probably either use a graphical CAD tool or a programming-based tool (like OpenSCAD). Although BeetleBlocks is graphical, it is more akin to OpenSCAD than a graphical CAD program. That’s because BeetleBlocks is–more or less–Scratch for 3D modeling.

Scratch is the graphical block-structured language developed by MIT for teaching kids to program. You may have seen Lego robots programmed with similar blocks as well as Android App Inventor. In this incarnation, the blocks control a virtual robot (the beetle) that can extrude a tube behind it as it moves. The beetle is reminiscent of the Logo turtle except the beetle moves in three dimensions. The system is actually closer to Snap, which is a reimplementation of Scratch that allows custom blocks.

Texas Instruments watch claims it’s a computer mouse

[Jack Toole] and his team [Aaron King] and [Libo He] sent in their computer interface dubbed the Chronos Flying Mouse. The video above explains the concept very thoroughly, but we’ll reiterate some of the highlights here. The project uses a Chronos EZ430 with its accelerometers to wirelessly transmit delta positions of the user’s wrist. Add a little open source software and you have a regular PC mouse, a video game joystick, a game wheel, and a few other different devices in one. We just love the suave feeling of snapping to click.
