Welcome to the website of the well’s first compact and fully portable, laser video projector in the world. This project has probably begun with my first visit to the IFA in the mid 90s. There I saw for the first time a laser video projection: Schneider (later Laser Display Technologies ) presented its vision for the future of television: Crystal clear pictures and extremely high contrast and excellent color reproduction. Unfortunately, these devices were prohibitive. I therefore decided a few years later to build your own laser video projector. In 2001 I took with this project in the contest youth research part and put the finished projector in the same year (only a few years after my first visit) at the IFA , the largest consumer electronics trade show in the world.
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.
