Raspberry Pi opens a lot of possibilities for do-it-yourself projects. It’s affordable and full of potential for implementing challenging projects. After having spent several years tinkering around my 3D printer, wanting to build my own 3D scanner to complete the 3D workflow was an exciting idea. Using MATLAB and the Raspberry Pi hardware support package for development made the experiment quick and easy, at least from the software perspective.
In this project, I decided to use one of the most basic scanning techniques – focusing more on getting the entire mechanism to work with off-the-shelf components rather than get the best possible results. Raspberry Pi serves as the main controller board for the setup, capturing the images using the Pi Camera, controlling the Line LASER diode and providing control signals to the EasyDriver (Stepper Motor Driver). I have used MATLAB and the Raspberry Pi Hardware support package to implement the algorithm and deploy it to the Raspberry Pi. This step helped me reduce the time required to setup the controller board, and allowed me to focus on getting the mathematics behind the scanning algorithm correct.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
