AquaTop works by projecting images onto the surface of the water. Mixed with bath salts, the water becomes milky-white and provides better contrast as a projection surface. The opaque water also reflects the infrared light emitted by a Kinect depth camera, which is responsible for tracking the position of multiple fingers – whether you hold them above the water, touch the surface from above or poke them out from beneath the surface. Both the Kinect camera and the projector are connected to a single PC.
This configuration allows for several innovative interaction modes, impossible to achieve with standard displays, such as scooping up a handful of water with a video thumbnail projected on its surface and then dropping the thumbnail over a video player area to start the video in full screen (or full bath) mode.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
