A very short update: there are more and more sprouts, however they are growing slower than I expected and there are a lot of sprouts on the wrong side of the vase. Need more light?   YES, the problem was definitely that the amount of light provided by LED strips (mounted on the edges of the Gr0G cube) and by the high efficiency grow LEDs (mounted on a standpoint in the middle of the cube) is not enough So the only quick-and-dirty solution I can apply right now is to provide more current ...
CONSTRUCTING THE BOT Robo Arm: The above picture shows the unassembled parts of the robo arm with 4 DOF.

Almost done with assembly!   Here:   Front view, powered off.     Power structure:   There are two 110V AC plugs required.

In the last Blogs, I have already mentioned somewhat details of what I am going to do for this 1m3Pi Challange, I loved working on the MQTT protocol. There are two BME280 sensors that are sending data with ESPs.   For the debugging purpose, I wanted to have all the sensors data on the LCD screen, which also looks nicer if I would make it somewhat fancier.   Nevertheless, I also tried to start both LCDs together but the LCD on the Enviro Hat isn't starting. The problem could be in ...

Design Features: This is a modular and scalable design. More water tanks can be added at any time and a single or more water tank can be removed easily from the system for harvesting the required amount of algae at a time.

My Background Hello! My name is Anthony Neil Tan and I am a UC Berkeley Bioengineering undergraduate. Last year, I competed in NASA's Growing Beyond Earth (GBE) maker contest with the goal of becoming a better engineer. 1 Meter of Pi is surprisingly similar to GBE, but this time around, 1 Meter of Pi is an individual challenge. I won't have engineering team members to fall back on, but instead I will have the opportunity to face challenges head-on and develop a newfound confidence in my enginee ...

We are already in the second half of the project and we want to see how we can help astronauts with this 1 meter of Pi project. So far, during this project, we realized that there are a couple of challenges in microgravity garden.   Let's recap a couple of challenges that we want to solve with this project!   1. Non self-pollinating plants need pollination --> how to monitor them and help pollination mechanically, bugs, or wind 2. We want to avoid bugs in space  --> Bug c ...
In this blog I will be setting up the Raspberry Pi. I got the Raspberry Pi 4 (2GB) when I got selected as a challenger. Then I bought the official raspberry pi type-C power supply and a 32GB micro SD card. I followed the following steps to setup the device: 1. Download the latest Raspbian OS image and the 'Raspberry Pi Imager'. 2. Flash the SD card with the Raspbian OS image. This created two partitions of the SD card. Boot files are written in the partition with name 'boot'.   I did ...
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.

I have been doing some research to do the lighting of the plants effectively. They are called plant grow lights to name it. I came across many new terms and methods used to illuminate plants Indore or even in space.   The plants grow with photons(light particles) being thrown on them at constant or varying intensity depending on their needs. Light intensity or how densely packed light is with Photons is measured with Mico-moles per meter square per seconds or PPFD(Photosynthetic Photon ...
I have developed the basic principles of motion and control for one of the most important aspects of my design proposals, the ‘GIZZMOTO’ special pump with a telescopic outlet/extension and a distribution head attachment.   The purpose of the system is to give the options of supplying Air – at ambient or increased temperature – or Moisture, in the form of atomised droplets – again, at a pre-set temperature – to each of four levels, where growing containers ...
