  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 ...
  Hi everyone ! Hope you all had a great Christmas and a Happy New Year.   Another weekly update, but with a bit more this week. We all know that the project timeline is ending, but I'm going to keep posting here until the first vegetables are harvested from the project. I will not end it on January 5th.   Fruiting We have bean pods starting to grow !   The lettuce and other vegetables are also growing well.     Code  I'm still having some "ghosts" t ...
Merry Christmas all !   Hope everyone is safe and sound.   Welcome to a new update on the Space Vegetables Project.   Not much has changed from last time, but here's the latest updates. Nutrients  Although the PPM has not changed much, I'm following the General Hydro (the Nutrients manufacturer) instructions. This is the 6th week, so, I'm changing proportions of the nutrients - as the plants grow, so they needs change - the need less of some nutrients and need more of oth ...
Hi all ! Hope everyone is safe and sound.   This little update is to share how I read the TDS value of the nutrients solution and make it available to the Space Vegetables Client. Hardware The sensor is from DF Robot . It measures the Total Dissolved Solids. It indicates how many milligrams of soluble solids are dissolved in one liter of water.   EC and TDS EC stands for Electrical Conductivity and TDS stands for Total Dissolved Solids (already explained above). They both are widely ...
Hello ! Hope all are safe and sound.   This is the last post about the software that drives the Space Vegetables Project - the client. More info on the design: Space Vegetables - #5 : System concept and design Space Vegetables - #6 : Software Design Space Vegetables - #10 | Software #0: Wiring and Python programs   The Space Vegetables server post   I'm going to split this post into 2 - this one is about the SpaceVetetablesClient.py and the other will talk about the TDS sen ...
  Welcome all to the latest update for Space Vegetables. Hope all are safe.   This week I've changed some things around the greenhouse because the vegetables are growing well. I'm guessing by the time the Astronauts reach Mars, they'll be able to eat something !   The vegetables are growing beautifully. You can't smell through the Internet, but they smell wonderful.  The tomatoes smell is my favorite. I'm now able to identify all the vegetables in the hydroponics ki ...
  Hi all ! Hope everyone is well and safe.   This is the update on the server side of Space Vegetables.   More info on the design: Space Vegetables - #5 : System concept and design Space Vegetables - #6 : Software Design Space Vegetables - #10 | Software #0: Wiring and Python programs     Hardware This is connected to a Raspberry PI 3B+ with the Automation HAT MINI from the KIT, that's connected to the water and air pump and the lights.   Software The "serve ...
  Hello all ! Hope all be safe and sound.   Welcome to the third update for the Space Vegetables Project.   Plants The plants are growing well, although I'm sensing a pattern and don't know why - or at least, don't know if it's from it. The plants in the top layer are growing bigger than the ones on the bottom.  The lights are the same and they are at the same distance from them (at least, apparently). They are the same quality - at least some, and they don't show the sam ...
  Hi all ! Hope everyone is safe and sound !   This post is just to share the contraption I made to read the PH level of the water. Because the PH sensor cannot stay in water for long - like the TDS sensor - I've build a small contraption to read the PH level and display it in a TFT screen I had laying around. Here's the schematics of the build:       The build is nothing fancy - a small wooden box with holes to the power button     Code  To be ab ...
  Hello all. Hope everyone is ok and safe.   In this series of posts I will describe how everything is wired, connected and talks with each other .   The following image shows what each Raspberry PI controls and how everything is wired     Relay 4 channels  I had to use a relay because the Air Pump is 220v and the Automation Hat MINI cannot handle that much voltage. Although the lights are 12v, my first attempts to control the lights just using the outputs we ...
  Hi everyone ! Hope all are well and safe.   This is the weekly update for the Space Vegetables Project.   The Vegetables are growing well. The beans - i hope - don't grow any more in height, because they already are reaching into the top hydroponics layer. I can already distinguish some plants from beans and lettuce. Others I'll need for them to grow a bit more .     According to what I can see, they are growing in good health. The beans roots are looking great ...
  When submitting this project, one of the requirements I've set was to have a script to post to twitter (at least twice a day) a photo of the hydroponics vegetables progress with some environmental status. Here I'm going to explain how .   Hardware This is installed in a Raspberry PI Zero W with a 64Gb SD Card. It's equipped with a RPI Camera NOIR 5M fisheye with 130 degrees.   Software The software is a simple python script that takes pictures every 10m, but only posts to tw ...
Hi all ! Hope everyone is safe.   This is the first post about the software side of Space Vegetables. Here everything will be explained and how to install and configure.   Everything installed and used in this post is installed in the Raspberry PI 4B 2GB and the Enviro HAT .   Inside the user pi home directory, at /home/pi, create a new directory called SpaceVegetablesWebServices. All the files will be created there (but not the database).   Hardware Raspberry PI 4B 2GB ...
Hello everyone ! Hope everyone is safe and sound.   Yesterday was the first week that the project went live and things are still pretty much in the beginning. Since my TDS sensor hasn't arrive yet, I'm following the schedule in the manual of the nutrients company. You can check this post - Space Vegetables #9 : "Huston, we have liftoff" - when the project went live .   It was time to add nutrients to the water (three part nutrients) and to check the PH level of the water - always ...
  Hi everyone ! Hope you all be safe. This weekend, Sunday to be more specific, was the time to transplant the seedlings to the hydroponics and start the process. At the time I didn't realize, but, boy, what a work...   Preparation Before moving the seedlings, the conditions in the hydroponics system had to be the ideal: Nutrients inserted and the TDS values between an ideal range PH of the water to be 6 . Nutrients For now and until a know a bit more, I'm going to rely on the in ...
