The system makes use of the already available hardware in the challenger kit, with some additional items.   Let me list out all the items necessary.   Raspberry Pi 4 MAX30102 sensor Pimoroni PIM487 Automation HAT PIM486 Enviro HAT PICO HAT Hacker PCB Insulated Copper wires for Anode and cathode linkage to the power supply Hot glue cylindrical pipe - a small piece Wire mesh Rubber tube O2 suction mask Buzzer RGB LED Power Bank DC power supply   The blood oxygen leve ...
Approaches:  Oxygen generator for a whole area (currently limited due to resource constraints) Portable oxygen generator for an individual (this project focuses on this) For approach 1, good quality atmospheric oxygen PPM sensors are costly and are out of our financial budget. One such module is AST SRZ-CA24-4 from OxyCheq.     For our demonstration, we use approach 2 where we use a MAX30102 Pulse Oximeter & Heart Rate Monitor sensor from Maxim Integrated.     C ...
Aim:  This project aims to tackle an emergency event of oxygen deficiency. In confined and restricted spaces, be it even a safe bunker/shelter during a global disaster, a workspace, or a rocket ship speeding to space and beyond, humans if present, will be needed to sustain the amount of oxygen for a prolonged period of time, within their body as well as the surrounding space. If personnel more than the allowed number are present in a confined space, oxygen can easily run out within that ...
In the last blog as I have mentioned, I got the box ready, now it is time for assembling the parts. In the next two blogs, I will explain the full project in detail with the code.   I assembled the LED lights on the top. Set the color of the lights to purple. Then it was time to put the RPI into the field. Here, I am using a power bank to power up the Pi. I am also placing the ESP's connected with BME280 sensors on the both of the sidewalls of the 1m3 of space.   Here, in the thir ...
  Hi all ! Hope everyone is well and fine. It has been a challenging couple of months . Thinking of the project, assembling the greenhouse, putting everything together, testing and production - it has been a wonderful ride. Always had a special interest in hydroponics and this project was the perfect excuse to try it.   I know it's not scientifically accurate - but NASA has spent millions to be able to grow radish in the International Space Station - and I don't have that kind of b ...

The autonomous pest management will take care of the elimination of flora and fauna pests in limited or confined cultivation.   The system consists of a Rpi 4 which acts as the brain. A Rpi cam connected to the Rpi4 will detect the presence of any pests via OpenCV and machine learning models. The PIM486 Enviro HAT will additionally detect any change in the ambient temperature, humidity, pressure, etc which can lead to plant decay. The PIM487 Automation HAT will control a set of servo mo ...
Introduction and motivation  This project introduces a novel concept of pest management in closed spaces such as space farming.   Be it a bunker or space vehicle with very limited space to spare, plant cultivation would be a major task, if the people inside the bunker/space vehicle are to survive for an extended amount of time. This also includes enclosed or partly enclosed structures on farms such as silos, vats, tanks, pits, etc.   But, with closed space cultivation has its adv ...

Constantly provide water 2. Non- ...
Below is the random writings throughout the project and well.......I decided this is a portion of the project book I created that has all my sketches and information in it.  For fun here it is more ramblings......   Entry #1 Sept 2nd.                The first thing I wanted to do in this design challenge was to get my thoughts in order. To start planning the adventure, to document as much as I could.  As I wo ...
It's been a long journey and I have plans for more to come when it comes to my build so the fun doesn't stop here.  I noticed when rendering my video a bunch of my video decided it would mess up so I have a few smaller shorter videos and information coming in regards to the project. I will say I was looking for a fun project for the winter months.  This certainly fit the bill on that one. I didn't realized how fun it was going to be,  I have learned a lot about pushing the limits ...
Like any project there is always alternatives that can be done.  I had thought a lot about this project prior to starting.  I was certainly trying to find out a way to make this project the most cost efficient and easy to build so basically anyone anywhere could reproduce it and be able to add on to it without any issues.  With most of our projects I am sure I am not the only one that is guilty of this and that is over thinking everything. When I started I had tons of ideas and th ...

The estimated setup is as follows:   * Rpi will be stacked with Rpi cam, PICO HAT Hacker PCB, PIM486 Enviro HAT, and PIM487 Automation HAT.   * It will contribute to roughly                L * W * H as 86 * 57 * (25 + 17 + 9)      = 86 * 57 * 51 (mm)                         &# ...
* As the theme of this design challenge goes, this project focuses on the sustainability of mankind in case of a global disaster or that of an interplanetary voyage. * The project is developed to have an autonomous self-contained system for plant cultivation so that the least human intervention is required for maintenance. * It is not only small in terms if footprint size, but it will be so small that multiple of these can be developed with ease and be put in various congested spaces within th ...
