The Ciclop 3D scanner is a 100 % open source project. All information on the mechanical design, the electronics and the software have been made freely available to the community. The aim is not just to study the scanner and understand how it works. We want the community to be involved and to make modifications, improvements and developments using Horus. We are committed to free knowledge and we want to use it to contribute to and drive forward the development of these devices. Ciclop is a 3D rotational laser triangulation scanner. It uses 2 lasers projected over an object to capture the geometry and texture as it rotates on a turntable. Ciclop has been designed with the setup process in mind. The kit includes all the necessary pieces and a step-by-step assembly guide, enabling you to set it up in less than an hour. The Horus software is a multi-platform application developed by BQ under GPL licence. The Horus interface can be used to calibrate the scanner, adjust the camera exposure or view the point clouds generated. Ciclop interacts with Horus via three workbenches: one to Control the components (camera, lasers, motor and LDR), one for Calibration of the scanner and one for Scanning. Ciclop is a DIY scanner and, as it is set up manually, the distances and positions of the elements of the final product are different, making it difficult to calibrate the device. This system has been designed to calculate the internal scanner settings automatically using the structure set up by the user, by auto-calibrating correctly. This means that we can guarantee a good result every time you scan. The ZUM BT-328 board, based on ArduinoTM, includes improvements and better features than other similar boards, which make it the best option for developing electronics projects. ZUM BT-328 executes the control firmware of the motor and the lasers. ZUM SCAN, a shield derived from Arduino CNC Shield, is connected at the top of the scanner.The worlds first truly open source scanner for 3d printing!
