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. 😊

But the progress so far is below in pictures.

Azure Percept – AI on the EDGE

Thank you for everyone that attended the two AI on the Edge talks at MSDUG Johannesburg and Cape Town.

As promised I’m sharing the additional content from the Azure Percept.

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. 😁

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

Sonoff RF Bridge 433 – Tasmota

Sonoff RF Bridges are great to take every day houshold remotes, alarm systems, passive IR seasons etc , and pass the codes they transmit via MQTT messages.

These bridges can also be flashed with the Tasmota open-source firmware used for Home Automation.
