It took a lot longer than I wish it had, but my LED Medalum from
@expedition33official is finally here! 💜⚔️ And yes, I know I don't make a very good Maelle...
In short, it's nearly identical to my original Medalum model - 42" long and uses an aluminum rod as its structural core to make it nice and sturdy. A super narrow 5mm LED strip fits within the blade, which is driven by a small microcontroller and powered by a 14500 battery cell hidden in the grip. The pommel houses the power switch, and also acts as a magnetic removable cap to gain access to the internal electronics.
To make this build easily approachable for everyone, regardless of experience with electronics, I include a full build guide with pictures, a bill of materials with links to the parts, wiring instructions and diagram, lighting code installation instructions, and a metal rod bending template. 3 lighting codes are provided with the files, as seen in the video.
I can't possibly go without crediting
@feistyfabrications for commissioning the very first LED Medalum nearly a year ago now! Without her, this version would never have existed. Thank you for getting me into builds with electronics!🙏
I also have to thank
@littleluckycosplay for providing feedback that went into developing this model, and for finishing her "early access" build before I could 😅 She did a wonderful job!
If you want the STL files (along with the build guide, lighting codes, etc.), they are available now on my Etsy, Cults3D, and Printables. Links in bio!
