The open-source, 3D-printed, smartphone-integrated microscope is the brainchild of Stanford engineer Ingmar Riedel-Kruse, who developed the device in a quest to find new ways for students to interact and learn about the microscopic world that surrounds us.
Until now, microscopy was a sit-back-and-watch-type of activity, Riedel-Kruse explains. “You can look through a microscope and see,” he says. “But you can’t really interact with what you see.”
The LudusScope is a simplified microscope, consisting of a base that holds the sample slide. The microscope’s lenses and a bracket for viewing through a smartphone are both attached to the upper arm of the device. Once the smartphone is attached, the user opens an app. Through one view, students can measure individual microbes and track their movement.

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.
