After discovering 3D printers, [Turi] had to make one. This past summer he did, and it looks fantastic.
He chose the Rostock design not only because it can print big parts quickly, but also because of its mesmerizing operation. 3D printers are generally fun to watch for the first few minutes, but Rostocks tend to have an even more robotic appeal in the motion of its end effector (robotics lingo for tool head).
The cool part of this build is [Turi’s] choice of enclosure. He had an IKEA cabinet collecting dust in his basement, so he decided to make use of its drawers for the main structure of the Rostock. A bit of wood work and some matte black spray paint later, and he has one great looking enclosure! The rest of the build was pretty standard, making use of 3D printed parts, a RAMPS 1.4 control board mounted on an Arduino Mega, and a computer power supply. He did make his own control arms using carbon fiber arrows, though!
To see it up close and in action, check out the quick video after the break.

Nothing reminds us that it’s the holiday season more than an LED Christmas Tree submission. This obviously is not the first of its kind, but [Jose] does offer up a new technique using addressable RGB LEDs.
[Jose] decided to use 20 WS2812B RGB LEDs, which if you haven’t seen before, are RGB LEDs with an integrated controller. Yep, that’s right, just power/ground and 1 data line is all that is needed to control hundreds of RGB LEDs. This LED tree’s design is simple: a custom-etched PCB cut it in to the shape of a Christmas tree. The WS2812B LEDs helped keep everything clean, so the tree lacks any ‘ugly’ ornaments, except for the required bypass cap here and there. For an added bonus, the tree’s LEDs are synchronized to music generated by an Arduino via a piezo buzzer. Why is it a shield? Well, the whole tree plugs in nicely to a standard Arduino interface. This looks like the perfect starter project to familiarize yourself with addressable LEDs, or at least to get you warmed up before building your own infinity portal.
