J. Chem. Educ. 2019, 96, 1152

100-USD handheld droplet imaging and analysis device built on a Raspberry Pi. It can take images at 3280 x 2464 pixels and videos at 120 FPS. It measures droplet size, dispersity, and intensity to display the results directly on its touchscreen. It is a low-cost laboratory tool for college students to get involved in droplet microfluidic experiments.
