Teaching with Raspberry Pi: Custom Case Project

thingiverse

Project #6 - Custom Raspberry Pi Case In this hands-on project, students will get the chance to design and print a custom Raspberry Pi case (version 2 or 3 ideal) for any type of Raspberry Pi project they can think of, such as creating a security camera. With numerous 3D printable cases already available online, students should be able to pick and modify one that fits their needs. In various industries like engineering and scientific research, custom parts are often required for specific applications. Students will learn this process while designing a custom enclosure for a mini computer (Raspberry Pi) that meets the requirements of their project. The sample 3D STL file included in this project was borrowed from user ftobler on Thingiverse. Print Settings Printer: Flashforge 3D Creator Pro Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: .27 Infill: %15 Notes: Depending on the quality needed for the case, these settings will work to make a robust case. Resolution can be lowered if a finer detailed case is required. Post-Printing The print came out okay in this shot. The case requires 4 screws to secure the Raspberry Pi. How I Designed This Example Project: Functional Raspberry Pi Security Camera Example Project: Security Camera with Battery Pack Standards NGSS Overview and Background Students in an engineering/robotics/computer science class will work together to create a custom Raspberry Pi case for any type of project they want to pursue. Some examples of Raspberry Pi projects include making a small robot, creating a camera, or making a small portable computer with an LCD. Objectives: * Students will create a custom case for a Raspberry Pi computer that can perform a specific task. * Students will collaborate to brainstorm and design a 3D model of their Raspberry Pi case that will support any attachments to the computer. Skills Learned (Standards): * HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering. Lesson Plan and Activity Step 1: Brief students on the project and the deadlines. Step 2: Allow students to brainstorm possible uses of small computers. Step 3: Show example videos/projects using Raspberry Pi computers for inspiration. Step 4: Divide students into groups of 4. Step 5: Allow students to create and modify 3D models of Raspberry Pi cases that fit their project. Step 6: Finalize 3D models and 3D print all the cases for all groups. Step 7: Program Raspberry Pi and attachments to function and test for bugs. Step 8: Assemble the Raspberry Pi with its accompanying case and attachments. Step 9: Debug and test for functionality. Step 10: Present to the classroom about the project. Step 11: Debrief activity and allow students to suggest improvements for future projects. Materials Needed * Raspberry Pi computers (at least 6) * Any relevant attachments for the Raspberry Pi computers * Microelectronic tools * Power source (cable with portable battery - Lithium Ion) * WiFi adapter for Raspberry Pi * Raspberry Pi computer * Raspberry Pi compatible camera * Case (3D printed) * MicroSD card (at least 8 GBs) Duration of Lesson This project will require at least 2 weeks to allow students to design, build, assemble, and program their Raspberry Pi computers with cases and attachments. The teacher should determine how much time is needed for each step. Preparation The teacher must have access to computers with 3D modeling software (ie: SketchUp, TinkerCAD, etc.). The teacher must also print out all the student-designed custom cases for the Raspberry Pi computers in order to complete the project. Rubric and Assessment None - Teacher may evaluate based on form and function of each completed project. References http://www.nextgenscience.org/dci-arrangement/hs-ets1-engineering-design
