Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Many Lunar New Year celebrations involve elaborate Dragon and Lion dances. Create your own mini celebration with the Adafruit Learning System and the Circuit Playground Express

This tutorial will show you how to turn an inexpensive Chinese dragon decoration into an animated stick puppet, and then how to take your dragon puppet to the next level, adding motion-reactive flame lights that create a stunning visual effect to mesmerize your audience.

This is an easy beginner-level project that involves a little bit of soldering. You can download our code sample, or learn to make your own flame effects using MakeCode, Microsoft’s drag-and-drop code editor. This is a fantastic project to do with kids.

It’s hard work being a werewolf, and I don’t just mean cleaning blood stains out of the carpet or dealing with fleas in the house.

It’s this messy business of the full Moon. Most wall calendars and news sources, if they even mention Moon phases, there’s about a 50/50 chance that they’re off by a full day (explained on the “Moon Facts” page). You might be out at a fancy event wearing a rental tuxedo when things turn weird. There goes your deposit. So awkward.

The only way to get a correct Moon phase for your time and location is with math and science. Our Matrix Portal Moon phase clock lets you know where things stand right here and now, portraying the Moon’s phase more accurately than a printed calendar, and whether it’s currently in the sky or has set.

So now you can prepare. No tux! Stay home and put on a comfortable flannel shirt like werewolves do.

Help ring in the new Lunar Year with Blinka! You’ll be endlessly charmed with this project from the Adafruit Learning System

This guide will show you how to build your own musical snake charmer box with Blinka, the circuit python! The materials you can find around the house and the project uses the Circuit Playground Express microcontroller programmed in Microsoft MakeCode for easy upload and changes.

Hacked smartwatches are everywhere nowadays. He’s a fun one. Simon Brem has transformed the PineTime smartwatch into a MIDI controller via Bluetooth. Here’s more from hackaday:

The project is based around the capable PineTime smartwatch, which [Simon] has been using with the InfiniTime firmware. On this platform, he created an app that sends out Bluetooth MIDI commands straight from the watch. It can be used as a motion controller, where waving and angling the watch can be used to control MIDI parameters, or it can be used to sync BPM to the wearer’s heartrate. [Simon] demonstrates an example use case in a demo video, where the watch is used to control filters in pleasant ways.

What is cyberpunk? You may not have a specific definition of the word, but here in our corporatist, AI-inflected, body-modded, post-plague world, you can certainly feel a particular cyberpunkish vibe. Somewhere in the Thatcher/Reagan crucible of the 80’s a new literary worldview peeked out from between the painstakingly crafted sentences written by William Gibson in his seminal novel Neuromancer. From there, cyberpunk invaded movies, fashion, critical theory, and, of course, video games.

A couple years ago, in an extensive review of the video game Cyberpunk 2077, game designer Tim Rogers laid out the most through exploration of cyberpunk ever released on the tubes of the internet. Maybe you don’t play video games. That’s ok. This “review” is about far, far more than video games. It’s long. It’s glorious. It’s experimental. It’s essential viewing. Here’s more from Tim Rogers at Action Button:

Action Button Reviews Cyberpunk 2077. Season One Finale. Presented with an introduction and seven stories with six intermissions. This video is absolutely not intended to watch in one sitting. As always, we strongly encourage you to consider this video a mini-series. For optimal enjoyment of this review we recommend following the instructions given in this introduction chapter. We tried a more experimental structure this time–a structure so experimental no existing app properly supports it. So we deliver this review to you with the smallest possible collection of necessary compromises…
