I now have some prototypes of LED rings with a dozen LEDs making it easier to do larger projects requiring more light diffusion. Big thanks to PCBWay for sponsoring these, amazing quality as always. This now makes a the current Glowstitch LED range include rings, strips with 5 LEDs and strips with a single LED for a great variety of projects.
Here's a short demo video of how these could be used for larger light diffusion. I some other ideas for using these include Iron man chest / glove cosplays, cyberpunk/tron paintings, halos and jewellery and more.
