Here you can find stuff I keep myself busy with when not at work! (Actually this is what I do for a living as well!) All related to electronics. I've included color pictures and some programs from my book "Complete PIC® MCU Programming and Project Guide" as well.

About

Although I am a very private and introvert person, below some information about myself:

I was born 27/07/1965 near Prieska in the NorthWest province in South Africa.

I am a C&IE engineer, married to Karin and have 3 kids, Chantelle, Janika and WF.

We live in Middelburg in the Mpumalanga province of South Africa.

My daytime work is in heavy industry, where I normally spend my time in management and projects.

I am a gadget dad, love my micro-controllers! I do programming, training and even workplace upgrades with them.

Career

My workplace beginnings and not so far endings ...

After my studies, I started to work as a Learner Engineer at the then (1989) Yskor in Vanderbijlpark, South Africa.

I was promoted to Tegnologist early in 1990 and left YSKOR in 1994, after 10 years. (5yrs bursary).

I joined Columbus Stainless in 1994 as the Maintenance Manager for the Continuous Caster and Griding areas of the Steel Plant.

My career there spanned 30+ years and was mostly in the Instrumentation field. I really enjoyed my time there.

At the beginning of 2010 I joined Assmang Manganese in Cato Ridge (between Durban and Pietermaritzburg) as Plant Engineer C&IE.

In September 2016 I joined Clifford Machines & Technology in PMB as their Mechatronic Engineer. I currently feel that it is not work, as I now do what I always wanted to do.

As a family we returned back to Middelburg in 2021, where I was the manager for JND PC and Pheripherals for 3 years, before starting my own bussiness in the laboratorium and instrumentation field.

This is in short what I'm upto relating to work. More can be found at LinkedIn...

Interresting things

I published a book, details under "Book"-tab. My IoT project for my house automation also have its own website!

Now available as e-book! (US$23.75)

This 967 page book covers the programming of PIC® microcontrollers in CCS C V5 in a practical hands-on approach. It also has complete examples of all functions and circuits for you to build and use. The PIC16F88 was used as a starting point, used here to connect various sensors. I then move on to stuff like TFT displays, USB, GSM and GPS. More information and how to order under the "Book" tab to the left. (or just scroll down)

What people say about me as person and author

ABOUT THE AUTHOR

Jannie Hamman is a well-known figure in the world of microcontrollers and robotics, which I have the pleasure of knowning for more than 20 years.

The author spent all of his working career as an Instrumentation Engineer in heavy industry, looking after various automation- and control systems. During this time, he designed, programmed and built 100s of microcontroller circuits used to solve problems and various applications (Black Boxes).

The author also trained many young and upcoming engineers in various fields.

Although an Engineer with a wide field of knowledge, he focused on micro-electronics, microcontrollers and programming and can write in total 18 programming languages.

This stretches throughout the whole spectrum from hardware PLA and assembler up to today’s 4th generation languages, including OS environments for Linux and Microsoft PC software.

The author has registered a few patents during his lifetime. He is currently working on IoT for use in home automation in his spare time.

This book is a must for any person interested in electronics and microcontrollers – all the information and examples you’ll find in this book are from real life solutions through the author’s career.

The book is an asset in your toolbox of knowledge.

BOOK REVIEW

We continuously define our own rules and boundaries throughout life w.r.t what and how we do things. Things referring to our engineering, programming, electronic hobby or work activities. I have come to know Jannie Hamman as someone who has a very unique viewpoint and constantly challenge these walls and boundaries. This book opened my eyes to different opportunities and possibilities whilst vastly improving my skills.

This book combines the worlds of electronic hardware and programming in a unique synergy. It provides the reader with the knowledge to realize his ideas and inventions with the underlying theme – If you can think it, you can build it. It diminishes the line of impossibilities as told by a person with extensive knowledge and over 30 years of experience in electronic design and programming.

The book is packed with knowledge, projects, diagrams and examples, but yet talks to you in a personal tone with a great sense of humour. Even if you are more inclined to the hardware or software environment, you will find the information you need together with the understanding required to finalize your potential. You will be amazed how you can interface old and new technologies. Get ready to even push the boundaries and completely interface your Raspberry Pi or Arduino boards!

Get ready for an exciting read and open the door to a new world of electronic interfacing. You will definitely read this book multiple times and still learn more every time. Remember, the best way to learn how to think out of the box is to ask someone already on the outside.
