3D Printed Greeting Cards

T’is the season to hack, and the maker brigade won’t disappoint — there’s no better way to crank out a few cute holiday tchotchkes than to fire up the 3D printer. [Niklas Roy] has released gDraw, a software package that creates G-code to print out 2D drawings on your 3D printer.

The interface is simple, allowing the quick and easy creation of basic vector drawings. The program then converts the paths in the drawing to a G-code representation that your printer follows to squirt them out in plastic. Think of it as the 3D printed equivalent of the “Stroke Path” …read more

Arduino Lighting Controller With Remote Twist

The time for putting up festive lights all around your house is nigh, and this is a very popular time for those of us who use the holiday season as an excuse to buy a few WiFi chips and Arduinos to automate all of our decorations. The latest in this great tradition is [Real Time Logic]’s cloud-based Christmas light setup.

In order to give public access to the Christmas light setup, a ESP8266 WiFi Four Relay board was configured with NodeMCU. This allows for four channels for lights, which are controlled through the Light Controller Server software. Once this is …read more

More Blinky = More Better – The WS2812FX Library

The WS2812 is an amazing piece of technology. 30 years ago, high brightness LEDs didn’t even exist yet. Now, you can score RGB LEDs that even take all the hard work out of controlling and addressing them! But as ever, we can do better.

Riffing on the ever popular Adafruit NeoPixel library, [Harm] created the WS2812FX library. The library has a whole laundry list of effects to run on your blinkenlights – from the exciting Hyper Sparkle to the calming Breathe inspired by Apple devices. The fantastic thing about this library is that it can greatly shorten development time of …read more

Christmas Lights Done the Hard Way

It’s that time of the year again when you gotta start worrying if you’ve been naughty enough to not receive any gifts. Hopefully, Blinky Lights will appease St. Nick. Grab a strip of RGB LEDs, hook them up to an Arduino and a Power supply, slap on some code, and Bob’s your Uncle. But if you want to retain your hacker cred, you best do it the hard way. Which is what [roddersblog] did while building his Christmas Starburst LED Stars this year — and bonus points for being early to the party.

For starters, he got panels (as in …read more
