Build Yourself an AI Powered Microscope – DevConf 2024

Thank you everyone who attended my session at both DevConf Cape Town and Johannesburg
I met so many awesome people during DevConf inside and outside of my session! Thank you for making DevConf 2024 the incredibile conference it was!

I’ve included the slides for those interested in building your own DIY Microscope, or something similar to help you with your own accessibility challenges. If you have an imaging device with some intelligence, there’s so many things you can do!

The project is using a Raspberry Pi 3B (4 and 5 works too). It is build using C# and .NET 8. The user interface is created using AvaloniaUI. There’s nothing better that Avalonia if you need to create small, incredibly fast user interfaces on Linux using .NET. I really recommend trying it out!

The backend is using Azure CosmosDB for storage. The MongoDB VCore Implementation. This is chosen for it’s vector search capabilities. Perfect for a conversational solution using OpenAI.

The slides can be found below

The whole premise of the talk was to inspire developers to think about using all these tech components in your toolbox. Both AI and IoT bits and use it for good. There’s so many solutions that could be created especially for accessibility, to make people’s life a little easier. This is also exactly why I created this Microscope, to solve my own accessibility problems when building IoT solutions. Think about what you could do!

I hope to see you next time! Happy building and learning with cool tech!!! 😍

Keeping your .NET Apps Alive with Supervisor

Supervisor as a Background Service Manager

Supervisor is a service which can be used on a Raspberry Pi to ensure processes keep running. If there’s an app that requires execution 24 / 7 then SuperVisor is perfect for this. Perfect for kiosk solutions.

1. Install Supervisor

Log into the Raspberry Pi

At the command prompt type: sudo apt install supervisor -y

2. Start Supervisor the Supervisor Service

At the command prompt type:   sudo service supervisor start

3. Create a Supervisor Process

Use an editor such as nano to create a project file project.supervisor.conf in the /etc/supervisor/conf.d/ folder

Add this to the contents of the file

Create file project.supervisor.conf in etc/supervisor/conf.d/
and put:

command=sudo dotnet /home/pi/MicroLights/MicroLights.dll


4. Request Supervisor to re-read configuration and Update

sudo supervisorctl reread
sudo supervisorctl update

5. Staus of Commands

sudo supervisorctl status microlights
sudo supervisorctl start microlights
sudo supervisorctl stop microlights
sudo supervisorctl restart microlights

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.
