Chipin Project: Card Reader

thingiverse

This is an intricately designed 3D printed card reader. Its construction consists of six IR LEDs and six IR receivers strategically positioned within a housing built from three distinct layers. The layers are secured together with M3 bolts, showcasing exceptional engineering. For further insights into the Chipin Project, please visit http://www.ionsystems.uk/ To assemble this remarkable device, print one of each part: top layer, middle layer, bottom layer, LED tray, receiver mount, and carefully apply black PLA at 0.4mm to all parts for optimal precision. Enhance the IR reflective capabilities by coating them with heat-resistant paint. The necessary electronic components include six Sharp IS471F sensors (available at http://media.digikey.com/pdf/Data%20Sheets/Sharp%20PDFs/IS471F.pdf), six Vishay TSAL7200 sensors (http://media.digikey.com/pdf/Data%20Sheets/Vishay%20Semiconductors/TSAL7200.pdf), and one microswitch with an unspecified model number. Follow these step-by-step assembly instructions: Install the LEDs and receivers into their corresponding mounts, and connect all pins. Consult the receiver's datasheet to understand the basic circuit configuration. The next steps involve securing the mounts to the top and bottom layers, ensuring that the LEDs are placed on the top layer while the receivers occupy the bottom layer. Bolting these two layers together seals the device, with a micro switch carefully glued between them, set to trigger when a card interacts with it. To mount this exceptional reader, attach it firmly using hot glue onto a piece of aluminum extrusion for maximum stability.
