[DaveMakesStuff] demonstrates a great technique for 3D printing a sphere; a troublesome shape for filament-based printers to handle. As a bonus, it uses a minimum of filament. His ideas can be …read more Continue reading 3D Printing a Nifty Sphere Without Supports
It’s the holiday season, and what better way to celebrate than to carve out some generative snowflakes on your laser cutter? [Bleeptrack] has developed a web-based tool that creates generative …read more Continue reading Laser-Cutting A Flurry of Generative Snowflakes
Diffraction gratings create beautiful rainbow patterns when interacting with natural white light, and [audreyobscura] was familiar with their properties. Thus, she set about producing an attractive 3D-printed suncatcher ornament that …read more Continue reading 3D Printed Suncatcher Shines in the Light
Sure there are the occasional functional Christmas tree ornaments; we had one that plugged into the lights and was supposed to sound like a bird gently trilling its song, but was in fact so eardrum-piercing that we were forbidden from using it. But in general, ornaments are just supposed to be for looks, right? Not so fast — this 3D-printed ornament has a 3D-printer inside that prints other ornaments. One day it might just be the must-have in functional Christmas decor.
Given that [Sean Hodgins] had only a few days to work on this tree-dwelling 3D-printer, the questionable print quality …read more

It’s that time of year again, and the Christmas hacks are flooding in thick and fast. To get into the Christmas spirit, the FoxGuard team wanted a custom ornament to hang from the tree. They may have gotten more than they bargained for.
It’s a simple build that demonstrates the basic techniques of working with DACs and scopes in a charming holiday fashion. A Tektronix T932A analog oscilloscope is pressed into service as a display, by operating in XY mode. A Teensy 3.5 was then chosen for its onboard digital to analog converters, and used to output signals to draw …read more

Readers of a certain age will remember a time when the Christmas season in the US officially kicked off after Thanksgiving. That was when advertisers began saturation bombing the communal mind with holiday-themed TV commercials night and day. Broadcast TV no longer holds sway like it did back then, and advertisers now start their onslaught in September, but you can put a little retro-commercialism back to Christmas with this 90s Christmas commercial-playing ornament for your tree.
The idea came to [SeanHodgins] after stumbling upon a collection of Christmas commercials from the 1990s on YouTube. With his content identified, he set …read more

Trimming one’s Christmas tree can be an enjoyable tradition year after year, but every once in a while some variation on the established order can be just as fun. Seeking some new ornaments to and desiring to flex his skills, Instrucables user [Gosse Adema] created a LED-illuminated, phone-controlled, deltrahedron Christmas tree ornaments.
Wemos DI Mini Pros are the brains of these little guys, WS2182b RGB LED strips — being the superb go-to’s that they are — light the ornament, and a 5 V power supply keep them lit. [Adema] used the Wemos specifically to create a web server unique to …read more
The great thing about holidays is that they always seem to require some shiny things. The modern version of shiny things seems to be LEDs and advances in technology being what they are, we now have amazing programmable LEDs. And programmable LEDs mean animated shiny things! Years ago, [wpqrek] made an LED ornament using discrete components. This year he revisited his ornament and decided to make a new, animated, RGB ornament.
[Wpqrek]’s build is based around five WS2812b strips connected to an Arduino Pro Mini. The ornament itself is a thick styrofoam ceiling tile cut into a star shape with …read more
