An Animated LED Fireplace Powered By The CH32V003

Once you’ve mastered the near-magical ability of turning your ideas into a piece of hardware you can hold in your hand, it’s only natural that you’ll want to spread the joy. The holidays are a perfect time to produce a custom piece of electronics for friends and family, but there’s a catch: going from making one or two of something to making dozens of them can introduce some interesting challenges. Not only will you want to cost optimize your design, but to save yourself some aggravation, you’ll likely want to simplify the assembly process.

The fifty electronic fireplaces designed by built by [Adam Anderson], [Daniel Quach], and [Johan Wheeler] are a perfect example of both concepts, and while we’re coming across it a bit late for this year’s gift exchange, we wouldn’t be surprised if these MIT-licensed beauties end up under a few more trees in 2024.

Vinyl Cut Your Way Into An Edge-Lit Glass Display

The chances are you’ve seen the myriad cheap copyright-infringing edge-lit acrylic displays from Chinese suppliers everywhere on the internet, and indeed, etching acrylic with a modest CNC laser cutter has become easily viable to a lot of us in more recent years. However, if you want to kick things up a notch, [Michael Vieau] shows us how to build a plaque from scratch using not acrylic, but rather etched glass to make the finished product look that much more professional.

There are a few different steps to this build and each one is beautifully detailed for anyone who wants to follow along. First, the electronics driving the WS2812 lights are designed from scratch based on an ATtiny microcontroller on a PCB designed in Fritzing, and the sources necessary for replicating those at home are all available on [Michael’s] GitHub. He even notes how he custom-built a pogo-pin header at the end of the USBASP programmer to be able to easily use the same ICSP pinout in future projects.

But since a lot of you are likely all too familiar with the ins and outs of your basic Arduino projects, you’ll be more interested in the next steps, detailing how he milled the solid wood base and etched the glass that fits onto it. The process is actually surprisingly simple, all you need is to mask out the design you want through the use of a vinyl cutter and then pouring some etching solution over it. [Michael] recommends double-etching the design for a crisper look, and putting everything together is just as simple with his fastener of choice: hot glue.

Much as there was an age when Nixie displays adorned every piece of equipment, it seems like ease of manufacture is veering us towards an age of edge-lit displays. From word clocks to pendants and badges, we’re delighted to see this style of decoration emerge, including in replacing Nixies themselves!

Deck The Cubes

deck-the-cubes

[MrBuildIt] has lived up to his name when it comes to this year’s Christmas decorations. He built a rig that spreads Christmas cheer from one end of the cubicles to the other.

In the demo video after the break you’ll see that the system is controlled by a nicely polished Android app. It lets you choose from three different Christmas songs (or no music at all) as Santa Claus makes his rounds. The app includes buttons for switching all of the lights on or off but we think it’s more corny fun to see then turn on as Santa flies overhead.

The sleigh and three tiny reindeer are suspended from a pulley system. When they make it to one end of the office a hall effect sensor serves as a limiting switch. From the look of it you’d think Santa will be flying backwards on the return trip but there is a servo that flips the thing around so that he’s going the right way.

This is quite a gaunlet to have thrown down when it comes to office decor. We’d like to see what geeky thing’s you’ve been doing with your own decorations. Get some details up on the web and send a link our way!
