Kalsi is an artist who has demonstrated a new system which combines long-exposure light painting and a 3D printer to produce three-dimensional colour objects sculpted out of LED lights.
The system essentially “prints” an object line-by-line, as with a regular 3D printer, but simply shines a bright light at regular stages of the process. The result is what appears to be a solid hologram — at least on video, where all the points of light are recorded and combined. The system has been in the works for more than a year, but Kalsi’s latest video is the first to demonstrate colour portraits. Other similar projects have been carried out with industrial robots or large-scale equipment, but Kalsi says his version relies on a simple home 3D printer (and some clever software).
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
