Chatswood Library, 409 Victoria Ave, Chatswood, NS, AU

OzBerry – Saturday, April 18th, 2026
Creator Space

Kids' Group Session: 10:00 AM – 12:00 PM
Special Home Assistant Design Session Part 2 10:30 to 12:30 (again overlapping with kids session.)
Lunch Break 12:30 - 1:00 PM
1PM Special Home Assistant Design Session Part 2 Continues and some more Python code and what other show and tell happens to be available on the day.
4 PM Pack up and dream of something else to share for the next OzBerry.

What do we need to bring ? Nothing or ...

## Suggested hardware

If you want to get started with installing Home Assistant.

• Raspberry Pi 5 or Raspberry Pi 4 with power supply (make sure to choose a model with at least 2 GB of RAM).
• Micro SD Card.
• Ideally get one that is Application Class 2. Check for the label A2 on the card. Application Class 2 cards perform better especially on small read and write operations and are better suited to host applications.
• Make sure to use a card that provides at least 32 GB.

Also bring a laptop to program your card. We will have 2 lots of internet connections and can also copy cards if that is quicker.

Sorry a Pi Zero W or Model 1,2 or 3 will not be enough :(

If that doesn't interest you I am sure that something else here will.

If you’ve got something to show off, teach, rant about, or demo — even a quick five-minute lightning talk — please tell me. We intend to have another good crack at programming the Home Assistant on Saturday and then continue with small sessions on how to add more and some extra tricks.
If we don't finish we may continue on in May.
I am really looking forward to catching up with everyone soon.

For those that really like to plan ahead, we will be meeting up on the third Saturday of every month except for July that will be on the 25th instead.

I hope that you can make it - see you soon.

Cheers Erik

Thanks to Simon, we have a Facebook page for OzBerry

Have you seen it yet ? If not why not ?

For the next meeting we are starting at the usual time ...
(10:00am-4:00pm) and I will appreciate some help as usual for the kids session in particular. I am really impressed with their Python and Pi skills and we hope to be able to keep up, and also introduce some new topics that work. I learn new things each week like how to debug "Scratch" Robots and how to get remote controls to work in the correct direction. If only I could learn to type as fast as these youngsters :)

So please come and go as you like, and don't let me stop you ducking out for some lunch or coffee.

If you have a child, It's easy to become a member of the library so that you can be issued with one of the kits. You need to see the library staff to book as well, as there is a limit of 10 because it gets too busy, crowded and noisy otherwise. So please book now to avoid disappointment.

Where - Chatswood Library.
Lower Ground, The Concourse, 409 Victoria Avenue, Chatswood 2067.
Parking is usually difficult and I prefer to use the Train or Metro or just park all day near Beauchamp Park and walk a few blocks for exercise.
The Metro may be down again, so it will pay to check if you will have a slow bus instead.

If you like meeting up with all different experimenters and coders then please come along. Also consider bringing a project to build and discuss problems you are having with the group - we will most likely have someone in the group that will know how to help.

OzBerry events encompass a wide range of Open Source Hardware and Software on many popular platforms, including but not limited to: Arduino, RaspberryPi, Beaglebone, Android and more… if it plugs in and is programmable then it's a good fit.

We share ideas and help each other solve bugs and design issues that might otherwise be difficult on your own. We try to exhibit both hobby and professional projects each month.

Beginners are always welcome, we often have beginner events running. If you are just curious or starting out, all you need is a laptop, we will get you started on one of Chatswood Libraries Raspberry Pi kits, with your library card. Or just come along and have a look, it's up to you. We can also shed some light on the ESP32, "Internet of Things" and LoRa.

Format
6 hours of relaxed, unstructured collaboration and learning, come and go as you please. Help others or ask for help with your project. No pressure. But most importantly, remember to "Be excellent to each other" - https://github.com/OzBerry/code-of-conduct

Share a micro talk. Get up and speak about your project (or another topic of interest) (optional).

Please let Jamie, Simon or Erik know what you would like a tutorial on, or even better, volunteer to present something new.

What to Bring
We suggest a laptop at a minimum. Your project if you have one, or some hardware that you'd like to tinker with.

If you are a member of the library or would like to join, there are various electronic devices you can borrow: mBots, Makey Makey, and a Droid Inventor and drumroll please ... Raspberry Pi's .
