Industry-grade microscopes are expensive, and modern cheap alternatives simply don't have great imaging capabilities, functionality or both. Furthermore, the several thousand dollar price tag on these instruments makes it almost impossible for 3rd world country hospitals and students interested in microscopy to get access to microscopy. Thus, there is a need for open-source microscopy. Additionally, there is the problem of e-Waste or "throw-away culture". This has become common in society today, as consumers throw out old devices when they purchase newer models. This ends up in landfills, and the rare and toxic materials used in many electronics ends up harming the surrounding plants and animals, which eventually works its way back to people.
OS-M (Open-Source Microscope) Mk 1 is one such solution to both of these problems. This prototype repurposes old DVD drives (e-Waste) for microscopy, in addition to creating a 3D motion stage for better imaging capabilities and potential for 3D scan ability. OS-M Mk 1 has a magnification factor of over 150x, with a cost point of under $120. The main costs are for the Raspberry Pi, PiCamera and Arduino.
In addition to the cost-effectiveness described above, OS-M Mk 1 is made using the classic DIY technique. There is no need for anything other than cardboard, duct tape, super glue, hot glue, hobby knife and screwdrivers for construction. There is no 3D printing. This leads to another key advantage of OS-M Mk 1 - educational value. The construction process for OS-M Mk 1 is very valuable for prospective engineering and biomedical students itself.
OS-M Mk 1 is the first version of this microscope, and improvements will be made as feedback is provided.
OS-M Mk 1 has been released. First full release was finalized on May 4, 2021.
In terms of hardware, an Arduino (Uno or other variants) and Raspberry Pi with a PiCamera are all required for this device to function properly. Additionally, 3 optical drives are needed. Cardboard, a hobby knife, soldering iron and hot glue are also needed for construction.
In terms of software, at least Arduino IDE version 1.8.13 (download: https://www.arduino.cc/en/software) and Python 2.7 (download: https://www.python.org/download/releases/2.7/) are needed for smooth operation. These are free to install.
