Edge Lit Pendant, Is, Well… Lit

Acrylic is a great material. It’s not cheap, but it comes in a wide variety of colours and styles and can be used to make some very attractive projects. [Geek Mom Projects] is a big fan, and whipped up some fun pendants for a high school Maker Faire.

[Geek Mom] has long been a fan of edge-lighting, as it’s a great way to make beautiful glowy projects out of acrylic. In this case a fluorescent acrylic is used with white LEDs to generate an eerie green glow, though it’s also noted that the project can be done with clear acrylic and color-shifting LEDs instead for an equally cool look. If you’re filming a low-budget sci-fi film, this could be just what you need.

The pendants made a great project for young makers to learn about LEDs, electronics, and technologies such as lasercutting that were used to produce the parts. With copper tape used instead of soldering and a CR2032 battery used to eliminate the need for a current limiting resistor, it’s a very accessible project that most teens were able to complete without assistance.

It’s not the first time we’ve seen edge-lit pendants, either. Alternatively, if you need your acrylic bent, there’s a tool for that, too.

  1. Oooof that pun.

    It looks like it would theme very well with an escape room.

    Maybe shape based? Hard to fit an RFID tag to it

    Could be keys around a spaceship or even Indiana Jones/Lara Croft style room

    1. Why would it be hard to fit an RFID-Tag into it? There are chips you can embedd into circuit boards (Murata Magicstrap), and other solutions that fit into the handle-part of a standard door key used for increased authentication security….
