Here’s a gorgeous Space Invader Pendant created by Richard A+ and shared in the Adafruit Forums. The Technical Support Engineers Bill and Mike are both huge fans!
I didn’t have a project box that small so I just cut up the Adafruit box and hot glue gunned it up. I had some window tinting laying around to darken the unlit LEDs. The frame and other stuff was just in my junk bins.
This is using a lithium Ion battery attached to a charging board. The switch on the side lets you turn it on or off and the button is attached to the reset on the Trinket. I made sure to cut a slot so I can access the mini USB on the Trinket to reprogram it.

Adafruit Trinket – Mini Microcontroller – 5V Logic: Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power.

Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!
