See-through skin
A ‘vein-viewer' works by using infrared light to image the presence of veins underneath the skin: The IR light is absorbed by the deoxygenated haemoglobin within veins. The locations of absorption and reflection are detected and the machine generates a corresponding projection using visible light.

Maroš, a student I’m supervising for his bachelor’s thesis is creating an Arduino Shield with a contactless optical laser distance measurement device. The raw signal coming from the sensor electronics is processed using a mathematical model of the sensor dynamics to get the reading in millimeters. If all goes well, the measurement will be also output as an analog signal.
