Paul Dipuglia
Customer Relationship Manager – Neutrog Australia Pty Ltd

“Manufacturing processes and products very unique to Neutrog.”

Paul Dipuglia has been working with Neutrog since 2009 and during that time has become an integral part of the Customer Relationship team.

Paul’s role involves him being out on the road most weeks as he meets with retail stores such as Bunnings, Mitre 10 and specialist garden centres and also conducts staff trainings.

Another key part of Paul’s role is with garden clubs and plant societies, who stretch from the east coast of New South Wales all the way back to Ceduna in SA. Paul visits these groups to talk about Neutrog, the research and development projects that are underway and the individual attributes of the products that Neutrog produce.

It’s through day to day contact with retailers and these talks with passionate gardeners across a range of varieties and applications, that Paul has developed an in depth understanding of why Neutrog products are distinctly unique to their competition.

Paul’s presentation included:

  • Company History
  • Credibility
  • Manufacturing/Composting
  • Products in development
  • Benefits of year round fertilising
  • Products and applications

Topic: Using an “Arduino” to build and program your invention.

Presenter: Stewart Jones

Have you ever wanted to build and program your own robot? Or perhaps a weather station?
What about a DIY home security system? Segway? 3D printer? Washing machine (probably not)?

If you want to build something electrical which needs some level of intelligence, you’ll need a microcontroller.
A microcontroller is a small chip with inputs, outputs and a memory.
It’s as simple as connecting your electrical components and telling the microcontroller what it needs to do.

This presentation will focus on the Arduino microcontroller which was invented in 2005.
There are now thousands of microcontrollers available, the cheapest starts at $5 (delivered).

Stewart Jones is a Mechanical Engineer at Normet Asia Pacific where he designs modifications for underground mining equipment and also bespoke mining vehicles for international clients.
Stewart gained a Batchelor of Engineering at the University of Adelaide and has worked in the mining industry for companies including BHP and Boart Longyear.
Stewart is a successful lawn bowler who had national success at the junior level.
When not working or bowling, he is programming microcontrollers, playing with his daughter, and sometimes doing both at the same time.

Guest Speaker:
Mark Thomson (Author – Inventor – Researcher)

Subject: Acronyms, Algorithms and the Attention economy.

Is there a place for inventors, makers and fixers in the cyber/physical world?

“I will be giving my overview of the work I have been lucky enough to do with Professor Genevieve Bell and a few other people.
It’s allowed me to get an insight into aspects of the how the new cyber/digital landscape is utterly rewriting the world and what it means for people like you and me – who are essentially still making/inventing and tinkering in the physical and tangible world.” Mark Thomson

Mark is the author of many books, including those about the illusive inventor Henry Hoke.
We will have three copies of Mark’s book “The Lost Tools of Henry Hoke” to auction off at this meeting, with three lucky people receiving a signed copy.

One of Mark’s many roles is: Advanced Research Director at the Institute of Backyard Studies
