IoT Pi Microscope v3

thingiverse

There's an updated version available now, released on December 14, 2018. The correct parts to print for the latest design are the ones labeled as v3. You'll also need to obtain the STL files for "microscope base" and "base plate". The new features include a camera mount that's compatible with the Raspberry Pi 8MP camera, Lego gears (a testament to my unabashed enthusiasm as an adult AFOL), objectives that are easily screwed into the bottom of the optical tube using metal internal threads, a 32mm mineral glass for the platform, integrated stepper motor mounting, a 3D printed rack attached to the optical tube, and a stronger overall design. This project has fewer parts to print, is just as affordable as before, and boasts an impressive open-source design that combines 3D printed components with electronics. It's pioneering a unique blend of these two technologies. Please follow the link to learn more about this innovative project on Hackaday. It won the "Citizen Scientist" award for the 2016 Hackaday prize. Here is the detailed build log: https://hackaday.io/project/11429-internet-of-things-microscope Description: We're building a low-cost IoT microscope based on the Raspberry Pi 3, using easily interchangeable glass objectives to provide various magnification levels (40x, 100x, and 400x). The Raspberry Pi 3 will handle control of the stepper drivers and Pi camera, enabling connection to multiple devices via a WiFi link. You can also hook up the microscope to a TV or computer screen to view the camera feed. Features: This microscope utilizes common microscope eyepieces and objectives, including a 10x eyepiece and a 10x objective for a total magnification of 100x. Other notable features include a stepper-controlled Z axis, remote WiFi control of the Z Stepper and camera feed, dimmable LED light, a slide platform printed solid with spring-loaded metal slide holders, side-facing focusing knobs on smooth-running metal ball bearings, and a 160mm 3D-printed tube to match the focal lengths of the glass lenses. Additionally, this microscope boasts a built-in Li-poly battery for power, as well as a large solar array to charge it in remote areas. Enjoy! Print Settings: Printer Brand: Printrbot Printer: Simple White Rafts: No Supports: No Resolution: .18 Infill: 20 Notes: Print any optical elements in black PLA or ABS. The slide platform should be printed solid, while the motor mount is the only part that needs support and can also be printed solid. All other parts can be printed with a 20% infill.
