Some costumes require custom mechanical props. Spiderman's eyes in recent movies have the mechanical-quirk. So reproducing that mechanism in real-life is certainly a Cosplay + Maker thing.
There's a lot of Cosplayers using LED Lights for highly color-accurate "glowing" effects (common for high-end Overwatch Cosplayers). Some cosplayers are just sewing / stiching things (which is fine: that's still a skill), but there are other cosplayers who are putting serious effort into their electronic components of their costumes.
