  Hello all ! Hope everyone is felling well and safe.   Although 1 meter of PI Design Challenge is officially over, I will keep posting until I have some vegetables out of it !   The plants are growing well, and the tomatoes are already touching the top of the greenhouse. I know I can trim them to keep them from growing taller.   There's been a rough days for temperature in my city. Thermometers are hinting temperatures below 0ºc , but in the greenhouse the temper ...
In my previous blog, you all learnt this is a simple control system that uses water, ventilation and light to grow plants in modular cells, In this blog let's connect everything and run it. Here's the logo of the Agrocube Let's get started: Use a 12V power source preferably a 12V battery so that it won't have a problem with electricity issues in developing country like India/Africa. This 12V will be used power the pump and also for LED's if required. So here's the connection diagram: ...
I will use these last two blogs to only document the project I have done so far. Though I feel that there is still many things on which I could improve, add more components and code but I am happy with what I was able to do in this challenge.   There are currently the following parts of the project.   Raspberry Pi 4B Pimoroni Automation HaT Pimoroni Enviro HaT DPS310 Sensor ESP8266 + BME280 (MQTT Publishing) WemosD1R1 + BME280 (MQTT Publishing) Esp32 Pico V4 + RGB LED Strip (M ...

Got my automation mini hat working now. Yay! excited to write this after a gap. Completely got delayed due to various circumstances, but I just don't want to give up. My plants didn't sprout properly due to 2 reasons one the seed I chose was spinach which is a spring crop unfortunately and took more time to come out due to cold winter here in Bengaluru. The second reason is the soil used was dense and might pressurise the seeds to stay in maybe         ...

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 ...

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 ...

Addendum A to Blog/Post Nine:   I previously wrote: “Note: In the original proposal I had included a Solar Panel (or a series of panels) to be sited at the very top of the Construction to provide additional back-up power.”   ADDS: As the application is indoors, today’s technology would not be practical. However, tomorrow’s technology could change that perspective: There are at least two areas of research from which practical experiments are pointing the way to ...
I was working on making a Box for putting the sensors and Pi as well as lights which have a relatively nice encloser. I went to one of the friends who could make such a box of a Wood   I don't know how good I was in building the box and also in the main part which was the automation of lights for 1m3 of Pi, but let's have a look at some of the photos.     I am also going to add the Peltier cooling system for the 1m3 of Pi Space.

This is the last blog required, as well as the last one documenting major changes..   This blog includes my final thoughts, and potential future direction.   Let's first jump into what I did in the past few days. I've made the system's pump system with a small container that stores water. It looks large at 16.9OZ (it's totally not a Pepsi bottle! Totally not!) but it is rather small considering the strength of the pump.   Here's the video demonstration of the pump blasting out ...

The whole blog   For the enclosure I used an old non-working fridge. Mushrooms and vegetables will grow inside the fridge, electronics are located just next to it. The reason for electronics to be outside is I need RPI to be able to connect to WiFi and it will be not possible from inside of metal fridge. The access side of the enclosure is covered with plastic film, to make humidification more efficient.   Here are the dimensions.   Fridge seems to be pretty big, so I thought it ...

So I decided I would add to the front panel it worked pretty good it's all sealed up on the inside and I just used some green tape to seal the front doors up.  So we should be good and sealed up now.  I will however shortly here have to get some more air circulation going on in the unit but that shouldn't take too long. Yup it's most certainly time to cut that glow down a bit. Yup that should do the trick.  I will be adding another panel to the side there and also get the ot ...

So now I have my watering system all setup its time to get to the planting so where do we begin.  I decided to use peat pucks for planting the seed as given anywhere nutrients and everything can be added to a system after the fact but getting the seeds started in a environment they are most likely to succeed was the thing I wanted to attend to first.  Mind you I wanted to be able to have the soil go to the top of my containers so I could have even holes on to when the plastic was over ...
When it comes to working the bugs out there is many things to think of first we have hardware related bugs things that won't work and then software issues where things wont work with what we have installed for hardware.  This can sometimes be challenging when using something like software that has been created by someone else where one could make a more simple setup work just as efficient but we have to consider time and resources and what is needed to be done to complete and get things goi ...
When it came to the software I was really wanting to try out some software I had seen which if I could do it over I would have done something differently but due to time and so much going on it wasn't in the books.  I had to make something work even tho it was a bit of a pain. So I decided to use TerrariumPi  currently it is only able to be run headless on the raspberry pi 4.   You can check out TerrariumPi over on GitHub here:  https://github.com/theyosh/TerrariumPI   ...
When I started with the electronics I scoured around my workshop to pull all the parts out of bins to see what I go, low and behold I had some items.  But not sure how or if they will work I decided to go ahead with the project of getting the electronics together.   I ordered some cheap parts as well and off to the races I went frantically trying to get things together.  Finding out things didn't work and purchased items were not labelled correctly on the listings causing som ...

Unfortunate turn of events  I was planning a build sprint from Christmas to the end of the contest on my off days for holidays. Did a lot of research, planned everything and gathered all the required materials (covid-19 definitely made that difficult). But unfortunately my region (Croatia - Sisak/Petrinja)  got hit with few strong earthquakes, the biggest one being 6.4 Richter. My family is ok, and luckily my house was built strong and 20km away from the epicenter so we didn't hav ...

As I am going to use RGB LED strips to provide proper lights to my plants, I have started to do experiments with the strips I have. The LED strip is 2m long with 60Leds/m. Each LED consumes approx ~60 mAmps. This means the entire strip would need approximately 7.2 Amps. The Led strip needs a standard 5V supply. So the adapter like the one in the below picture should work to supply the required Watts to the strip.   Now, the RGB Led's have +(plus) and -(minus) as well as DIN pin to sen ...
