It consists of a small Tim Holtz Lantern that had an incandescent bulb powered by 2 AA batteries, which I retrofitted, removing the cheapo flashlight bulb and replacing itwith a white LED. The wires run through black necklace chain to a battery pack that my friend will wear tucked in her corset.
The battery pack is a cool little case from New Age Electronics (via Mouser) that combines space for 2 AAA batteries (more than enough juice for this) and space for a small circuit board on the opposite side.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
