Following the installation of Sue's wheelchair lift through the floor into the back bedroom the room no bed would fit in there and it became unsuitable for its original use. Rather than waste what space there is in there I decided to 'reallocate' some of it to be used as a shack. There is a separate article on the new shack design and development.
The shack is home to several aspects of the hobby, voice, data, APRS etc and much of the equipment is powered either by mains or 12 volt. It is also where I keep the Network Attached Storage device and weather station which updates aprs.fi and Maghull Weather.
With several devices needing to be able to shut down cleanly I searched eBay to find an APC uninterruptable power supply, it being duly purchased I hooked it up and this powers all the equipment in the shack.
The next section covers the power supplies.
