It's been a long time since I last posted a project log and I've been trying to get myself to writing this one for a long time. I started writing it a long time but my computer crashed mid-log.Anyway. I left the strawberry resting on the windows sill...
Currently, I am checking the new PCB and changing the code. As soon as it's ready I'll publish it. Corrections: There were2 errors on my PCB one on the pin of the DHT22 and one on the 5V pump which consumed too much power for the 2N7000. Everything...

Since last post we've won a LightBlue Bean from http://punchthrough.com. It is a neat little Arduino compatible bluetooth dev board, hopefully we can integrate it into our project. The first step to this project is to get a simple hydroponics system...

Of course the first thing that comes to the average makers mind when they want to add smart connectivity to something is the venerable Raspberry PI. These boards are great, but almost impossible to find in quantity and definitely impossible to buy at...
The LCD is a 40x4 character display. Judging by my friend [Eric]'s@EricHertz photos, this is not the common HD44780 device, but instead a Mitusbish M50530 I did find a datasheet for this device. If it's not code compatible with the '44780,...
The LG display allow to select the LVDS mapping between JEIDA and VESA. I encountered such issue again and images were generated to help diagnose the issue.The original image is pass through the conversion mapping to obtain the VESA and JEIDA images.----------...
This latest version of the board allows you to choose what you want to monitor in the tower. This board has been designed to be modular to suit your needs. We will look at each module one by one: Main module : This module is mandatory. It is the brain...

Like the previous PCB, you can choose the modules you want. This board has been designed to be modular to suit your needs. Update : - New alternating current circuit for disks and current control circuit (log)- Power supply voltage changeover from...
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...
Well despite the lack of proper automation (my controller is currently out of action while I fix the water level sensor problems), there has been good growth!Unfortunately my plants have been showing some nutrient deficiency problems, such as yellowing...
Microcontroller:The chosen microcontroller is an ESP32 because: The high frequency generation is simple Bluetooth and WiFi (to communicate with a phone or send data over the internet) Low power consumption Capacitive touch GPIO (water...
UltraTower is a low cost ultraponic system under 100€ with parts that can be easily found in shops. Thus this technology can have several uses:On a balcony:Cities are getting bigger and bigger and have a garden to grow your own vegetables can...
