Electronic and Technical Services (E&TS Ltd) was established in 1974 by myself - John Walker and became a limited company in 1992. I worked for a number of years in the R&D department  at the Associated Octel Company in Ellesmere Port, Cheshire as an Electronics Technician. Rather foolishly I left in 1974 with an HND+ endorsements with a burning desire to revolutionise the field of electronics. Had I stayed with Octel I would have retired at 50 with a £100 000 redundancy and a £20 000 year pension,oh  to have the vision of hindsight. However I have no regrets, I have designed a plethora of electronic controls some weird some wonderful and some with a good end application and I have met a full cross section of society, some strange, some weird but mostly interesting individuals.

It started in 1974 with the Jones - Rothwell Evaporimeter, used  in horticulure to measure evaporation loss in glasshouses. A local grower had one and said 'how wonderful it would be if it could be automated to turn on his irrigation controller for a known evaporation loss'. Never one to back away from a challenge and considering myself to be an electronics 'whiz kid'  or so I thought,  considered it straightforward  - dreadful mistake -  difficult to make, awkward to set up and problematic to maintain. Automation of the device proved to be exceedingly difficult. However I still have glowing reports from happy customers who bought the Vapomatic as it was called. I still have a mothballed but functional unit. I decided to stop making the Vapomatic due to the difficult manufacturing process and more to the point I lost money on every one sold.

However it is good to report that 37 years later, the latest descendant of the Vapomatic - the award winning Evaposensor is accurate, reliable, easy to set up, easy to maintain, and manufacture using the latest in electronic design, combining analogue and digital disciplines, backed by years of Defra and HDC research and successful nursery trials - and yes I have happy customers and more importantly make a (small) profit.
Thirty seven years with responsibilities and bills to pay concentrates ones mind on solving engineering problems across a wide spectrum ranging from commercial horticultural controls, all listed on this website, through to ABF's (automatic bog flush) controls, used in gents urinals and lottery terminals for the now defunct Big Chance Lottery. These terminals were designed around modified Interak Z80 computer boards. 
In fact, as long as it was legal, no engineering challenge has been turned down. The list is finite but lengthy and will include under a separate tab, later.

The current product which is still ongoing but thankfully nearing completion is the ClubAlert and BagAlert devices.
The latest design projects are a portable battery powered oxygen analyser, which will store dissolved oxygen samples down loadable to a P.C and a dosing control for chlorination of potable water.
I have no intention of retiring and as Poirot would say; 'as long as the little grey cells carry on working' so will I.
