Our principal and founder, John Jeffery, has been involved in electronics for about 40 years. He was originally employed by the NSW government where he was involved in instrumentation. This was when an IC op-amp cost 2 weeks pay, a computer with 16k of memory cost around 10 years pay and a 1Mb disk drive stood 1.8M tall.
An overland trip by Mini Moke to England via India, Pakistan, Afghanistan and Iran followed. While in England he worked on machines producing crystals for LEDs and was involved with the team designing the world’s first solid state telephone exchange.
Returning to Sydney in 1974 he became involved in industrial electronics, mainly doing retro-fits and upgrades. His work mainly revolved around replacing vacuum tube and electro-mechanical systems with solid state and microprocessor controls. These machines varied from tablet counters and labellers to production seam welders, machine tools and variable speed drives.
Major projects at this time included the complete electrical/electronic systems for machines that manufactured the first wine bags in Australia. These machines used phase controlled impulse welding of the foils, high accuracy motion control and PLC overall control. Various different machine configurations were operator selectable from a simple mimic panel.
Another major project was the design and programming of the LED signs still in use at the check-in counters at all major Australian airports. These utilised Z80 microprocessors and the software was produced on a Dick Smith System 80 computer, complete with 16k of memory. The originals used red for Ansett and yellow for TAA.
In 1986 he started Engineered Electronics and continued to produce original designs for industrial applications.
In the late 1980s it became apparent that most components were coming from interstate and that the customer base was also becoming Australia wide. So, Engineered Electronics left the pollution and crowds of Sydney and relocated to the eastern shore of the beautiful Derwent River in Hobart, Tasmania.
