Examples of modularity are things like cars, computers, solar panels, lego blocks and biological cells. Principles behind modularity posit that systems should be built from cohesive loosely coupled components, sometimes referred to as modules, with a defined function or purpose. The FlyPi is designed in a modular fashion to optimize diverse capabilities. The base pieces are the raspberry pi, raspberry pi cam, the PCB with the Arduino and the 3D printed housing. The raspberry pi acts as the computer for the camera and the PCB/Arduino controls the mechanical functions of the modules. Modules include the Peltier module (temperature controlled plate), the multicolour LED ring, the UV light, the fans for the UV light and Peltier, the thermostat and the indication LED for the Peltier. It's important to point out that all modules do not have to be added which can save time and money. If desired, modules can be added at any point. To begin, I determined which modules I wanted to have. I decided to keep all but the servo motor that provided some (x,y) axis movement for the slide. My samples were large enough that manual movement would be sufficient. I also knew I wanted to customize the design for an (x,y,z) axis movement to a hydraulic syringe that could be manually manipulated(that's another tutorial).ally manipulated(that's another tutorial). +

The repository has a detailed bill of materials that can be tailored to specific needs. * Electronic parts can be ordered from this kitspace page (lists have been conveniently compiled in various online market shopping carts): https://kitspace.org/boards/github.com/prometheus-science/flypi/ * 3D print files can be found in the files tab above. I started printing at the local fablab (fabrication laboratory) after ordering the parts I needed to build the microscope. This way I would have the body ready when the electronics arrived.e the body ready when the electronics arrived. +
