Considerations and Justifications for Choice While we were in possession of a biological microscope with an existing base, the original base was a heavy and bulky piece of metal. As we intended to mount the microscope onto the Creality Ender-3 3D printer frame, we found the base bulky and decided to redesign the base using […]

Considerations and Justifications for Choice The back of the raspberry pi touchscreen is not a flat surface as the raspberry pi is attached to it. Hence, a support structure to prop the screen up is required so that the wires at the back can be connected to the raspberry pi smoothly. Furthermore, it is more […]

Considerations and Justifications for Choice As we detached the eyepiece and objective lens from the microscope to isolate x and y-axis control, the eyepiece and objective lens require a support structure for mounting onto the 3D printer frame. Prototyping Process: Cycle of Test, Critique and Re-Design V1 Designed a lens adaptor with a sharp-angled slot to […]

Considerations and Justifications for Choice As we dismantled the microscope, a frame is needed for the mounting of the components.  Prototyping Process: Cycle of Test, Critique and Re-Design V1 Our original idea was to build an aluminium frame from scratch to separate the axes for remote control of the microscope movement. However, to build a frame […]

Considerations and Justifications for Choice For automated cell counting to be performed, the image of the sample slide needs to be transmitted. In this case, we planned to mount a webcam onto the eyepiece lens and send the microscope field of view to the computer. Hence, a support structure is required to affix the webcam […]

Motivation To make our setup more mobile, we wanted to have an onboard controller to move the microscope in space, along with acquiring images and performing our image processing. In principle, this would remove the need for any bulky laptop devices to be connected to all the devices, and allow our setup to be more […]

Considerations and Justifications for Choice The automated cell-counting microscope should be designed with the end-user in mind. In this case, they are likely non-technical people such as biological sciences researchers. An interface would allow them to interact and use the prototype without having to handle code directly. Prototyping Process: Cycle of Test, Critique and Re-Design V1 […]

Background The RAMPS 1.4 board is compatible with Marlin , which is firmware that acts as the interface between higher level serial inputs, and the RAMPS board.  The RAMPS board serves as a shield for the Arduino Mega, which extends its functionality, and uses the output pins of the Arduino Mega to control the RAMPS […]
