The power of Photogrammetry is quite amazing. The ability to accurately create an object from a series of photos never fails to amaze me. I take you on a basic journey into the dark art of scanning an object to create some solid 3D data that you can then use your favorite CAD application.
I cover how to prep the object you want to scan, mount it properly, set up you basic lighting, and the basic concept of your camera set up. Following some simple steps should yield decent, usable results.
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.
