Data Saturdays Cape Town 2023

Thank you so much to everyone that attended my session. It was a lot of fun and the audience was great!

Also thank you to the sponsors for making community events like this happen, the organizers and the amazing venue at the University of the Western Cape.

Here’s the slides as promised and also all the links to further learning and also links to our Cape Town MS Developer Community was more tech learning fun.

Home Agri-IoT experiment Part 2 – Composting

The home farm is working well, but time to try and make some improvements. I’m going to try my hand and “Smart” Composting. Going to start with a Bokashi and also some worms with VermiComposting.

More on the home Smart Farm here. Since this talk at DevConf 2023, I’m so happy and also inspired to see so many new home farm smart farmers!

Composting is a given as the soil here in the garden is not great.

Sensors and likely some AI is a given here to mazimize the output of the compost. I’ll post more on how things go and what I’ve learn from the process. It will be a lengthy process to measure the benefits.

Step by step instructions, when I know what I’m doing will follow. ๐Ÿ˜Š

But the progress so far is below in pictures.

DevConf 2023 – Create the sustainable home farm of your dreams!

Thank you everyone who attended my session at both DevConf Cape Town and Pretoria
I met so many amazing people excited about creating a more sustainable future.

This is a quick blog post which includes the presented slide deck. I hope attendees found the talk useful. It’s a very broad topic and fitting months of content into 40 min is a little challengening. So the presentation is a broad overview of the completed farming project project and there’s links to more deeper content within the slides. This includes content and github repositiories with some source code examples. The plan is to also release ALL the content eventually as a full OSS project when I’m happy with it, including the Mobile App and integrations with the cloud components. I’m currently rounding everything off to do this. So expect a few more posts about this and source code.

The slides can be found below

There is also Agri hacks planned where we can hack and learn about this topic together over a few sessions where you can learn hands on how to build something like this project. This will be a free to attend event held at @CPTMSDUG in Cape Town. Keep an eye out here:

This hack series be similar in format to our current IoT AI hack series currently running. You can see some of the fun had here at the all day iot hack events:

Additional Information

I received so many questions on how to get started. I suggest getting the off the shelf kit I mentioned in the talk that I started with. It contains everything you need to grow your first plants. This is also an indoor grower, so you can start with growing from seeds indoor and not worry about weather and protecting the electronics against sun and water. It will also make your home office a lot prettier. ๐Ÿ˜Š

What’s in the kit


4 x Solenoids (for 4 plants)

4 x Relays

4 Moisture Sensors

1 Pump

Silicon Piping

The kit is great to learn with as it’s not a “black box” watering system. It’s an arduino where Elecrow provides the source code to flash onto the arduino. It works out of the box, but it also allows you to learn from it and also make changes.

Please don’t start by hacking it like I did. I decided it should to be connected to Azure IoT. That’s definitely not needed especially when starting out. But the instructions are there if you want to do that too. ๐Ÿ˜Š

For the beginner this is great and as you could see in the talk, once plants start multiplying, you are forced to scale from there. ๐Ÿ˜

Once again thanks to everyone that attended both my session and DevConf 2023 and made the conference the amazing conference it was!

Azure Percept – AI on the EDGE

Outdoor Irrigation

For this outdoor farm to be truely sustainable I decided to water it with rain water tanks and have it self powered by the sun with solar panels.

The Outdoor IoT Farm Begins

It’s time to start moving the indoor IoT Farm to being an outdoor IoT farm. The idea I have is to do some experimentation and research into creating automated constrained space farms. I’m going to turn this into a hands on hack series for the CPTMSDUG user group and also share the learnings. Hopefully it goes well. ๐Ÿ˜

Today was the big shopping day to get everything I need.
