This guide describes how to build what’s commonly called a light table or lightbox. It places a light behind the guide sheets, writing paper, and more, making it much easier to see through. Light tables are also handy for slide photography, tracing, and reading film x-rays!
You can buy a simple one fairly inexpensively, or a professional quality one for much more. But that’s not what Makers do; we build our own!
This guide uses the Feather nRF52840 Express as the controller for the project. It provides plenty of processing power to work in CircuitPython and, more importantly, it has a solid Bluetooth capability. The parts are 3D printed.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
