International Cosmic Day 2025 at the library and makerspace.

The new indoor paper #rocket #holiday program ran just as well as our outdoor air-water rocket program. Some exploded on the launch pad, only one got stuck in the roof :)

How do you build a paper #rocket launcher?

Just completed a new indoor #rocket launching system.

Today, the #PAE #Libraries #STEM team explained #rocket #science to 20 children and their families. The children then built and launched their own air-water rockets on Semaphore Beach.

The first pre-launch system checks begin, parts counting charging batteries, making minor repairs, lubricating and pressure testing.

A very special new type of component I'm going to experiment with.

David Riley and I are presenting today. Sustainability in our STEM and Makerspace programs at PAE Libraries. #InfoOnline2025

In my spare time, I make #Cosmic Ray #Muon Detectors. This was designed and built to be a part of the 2025 #MOD #Museum #Forever Exhibition. It is an open-frame design, showing the internal electronics and #Geiger-Müller Tubes. More details here cosmicray.com.au/cosmic-forever

#EveryThingOpen that's a wrap hung up on the family conference badge hanger.

I've been involved with social networks from a young age and made many friends over the years, first CB Radio, then electronics and computer clubs, pre-internet BBS and Fidonet. Then, in the Internet era, IRC, Maillists, Forums, FB, T, YT, G+, etc., waiting for the next new thing and more friends.
