I hope that you find this web site interesting and informative and a catalyst to making the best use of technology to improve your lives.

Personal

Here I give some information about myself and my career in the music, defence and information technology industry as an electronics engineer, and as an auditor and accountant.  I am currently in the Hampshire Police Independant Advisory Group (IAG). 

My interests energy efficiency and being green, motoring, technology, pop music and pop concerts, photography and keeping fit and active.  This website is a mirror of https://johnperry.org.uk

Energy Efficiency

Our bungalow was built in 1989; we describe the energy efficient features that are built into the property to keep running costs low; we are all-electric with no gas supply by choice. Heating is solely via highly efficient air-sourced heat pumps. 

We use solar panels with sophisticated energy controls to make best use of solar energy and to keep running costs low.

Technology

These pages explain how we use technology to create a comprehensive and user friendly Entertainment System that allows the distribution of Satellite TV, FreeSat TV, VHF FM radio, video, music and data across our property in a secure manner with up to 10 F-type sockets in each room that can we easily re-configured.  The site also gives some, but not all details about our Security System of which some is visible while other features are hidden and will not be explained here.  Our Computing System supports the Entertainment System and Security System and is based on a hard wired CAT6A 10Gb LAN with multiple CAT6A sockets in all rooms and close to all TVs. Only the highest quality components are used.

Ventilation System

Here we describe how our ventilation system has evolved from a passive mechanical ventilation system with heat recovery to a microprocessor controlled ventilation and heat recovery system that has a built in heat pump for cheap heating in winter and cooling in summer.  The significant benefits of using a ventilation system are described.

I also cover our air-sourced heat-pump system that provides our sole source of winter heating and summer cooling; this was installed in 2019.

X-10 Home Automation

X-10 is a USA home automation protocol. 

These pages: explain the types of devices, show photographs of the devices, describe how the devices can be used; and explain how USA purchased modules can be modified to operate from the UK's 230V supply rather than the USA's 115V supply. 

Modifications are carried out at your own risk since the guidance here probably violates all UK Health and Safety Regulations.
