Neon signs are attractive, but require specialised tools and skills for their manufacture. If you don’t have time to learn glass blowing and source the right gasses, you’re pretty much out of luck. However, EL wire can give a similar aesthetic, and with an off-the-shelf power supply it is easy to hook up and get working. [sjm4306] combined this with 3D printing for a quick and easy build.
The project starts by selecting a Nintendo 64 neon sign as a basis for the design. An image of the sign was traced in Inkscape, and an outline imported into CAD software. From there, a frame was designed with posts for the EL wire to wrap around, and holes for it to pass through to the back of the sign. The frame was then 3D printed, and laced with EL wires in the requisite colors.
The final result is impressive, with the EL wire serving as a great small-scale simulacrum of neon tubes. It’s a construction method that should scale as large as your 3D printed assemblies can go, too. If you need to get to grips with how it works, there’s a tutorial available for working with EL wire. Video after the break.
