Ornament ring box4/22/2024 (You might be able to find most of the parts for lower cost at places like Aliexpress, Ebay, Banggood, etc) This can be bypassed, so if you want to be flexible, you can just order the wall powered PCB version. The only difference between the wall and battery boards is that the wall version includes a spot for a logic level converter. As with that instructable, all the ordering defaults should be fine for this project.įor the battery powered version you can use the PCB files found here.įor the wall powered version you can use the PCB files found here. I briefly go over it in Step 2 of one of my other instructables here. If you've never ordered a custom PCB before, it's easy. Suppliesįor both battery and wall powered options you'll need a custom PCB designed by myself. You can see instructions for ordering assembled PCBs in step 4 of my other Instructable. This will probably save you money if you want a lot of rings. The files are only needed if you want to have a set of rings manufactured by someone like JLCPCB. LED PCB Ring Files (designed by me): Link to files and Link to schematic. (The Mk2 and Mk3 boards will be used in this Instructable) If you are interested, you can view the PCB's layout and schematic here. For Battery Powered: Mk2 Board (You can also use the Mk3, the only difference is the inclusion of a logic level converter, which you can bypass).Unfortunately, at this time, my code doesn't include support for these, but I hope to add it in the future!įinally, if you have any questions at all please post a comment and I'll get back to you :) Likewise, using the Wemos D1 Mini allows for wireless control. My custom PCB also includes mounts for a MAX4466 microphone board (for audio based animations) and a HC-05 Bluetooth board. This can probably be extended quite a lot by limiting the effects and brightness.Įverything on the PCB is through-hole mounted (except for a few 0805 resistors used in the wall powered version), so it should be easy to solder.īefore deciding between the wall or battery powered versions, I highly encourage you to read the whole instructable before choosing, as the parts needed differ slightly. Using the battery should yield about 3-4 hours of run time using my default settings. The PCB can be adapted to be run from a LiPo battery or from a 5V wall adapter. To control the ornament I'm using a Wemos D1 Mini mounted on a custom PCB that I've designed. If you have never worked with WS2812B's before, I would suggest reading Adafruit's guide for an overview. Hopefully this will be helpful if you want to do your own control setup. I will provide versions of my code for both Arduino (Uno, Nano, etc) and ESP8266 (specifically the Wemos D1 Mini). However, there a a ton of different ways you could control the ornament, so I encourage you to use whatever setup that you prefer. In this instructable I will show you how to make both the ornament and my control board, including battery and wall powered versions. At this size, it's small enough to comfortably hang from a tree, while still having plenty of LEDs for animations. The outer diameter of the ornament is about 90mm. The ornament I'm presenting to you today uses 61 LEDs distributed across 5 rings. You also can make the ornaments smaller or larger by adding or omitting rings (you would have to change a couple of lines in my code though). You can usually find these rings as a nested set, so soldering them together is fairly straight-forward. The ornament is assembled from WS2812B LED rings. (please note that the LED colors look much better in person than in the video above) I have since updated the ornament, which I'll present to you today. My mom suggested putting the rings on our Christmas tree, and so, after some soldering (and some crafting help from mom!) my LED ornament was born. This addiction more or less began a few years ago when tinkering with commonly available WS2812B (aka Neopixel) rings. Hi and happy holidays to you all! If you take look at my profile, it's clear that I'm somewhat of an LED addict.
