A Lucky Find

I love second hand shops. I can spend hours in them sifting through stacks of records and rummaging through boxes of bric-a-brac. You never  know what you might find from one week to the next. It is also important not to dismiss the humble box. Open it and look inside, you never know what it might contain. It was just such a box that caught my eye this morning in Long Sutton. The box in question was quite blank apart from a BT label. Opening it, I found two mains plug adaptors, both wrapped and an Ethernet cable. There were no instructions but on closer examination, I realised what they were.

A few years ago, I had read an article about how someone was experimenting with the mains circuit in a house and using it to transfer data from one point to another. In effect, it was being used as a data network as well as carrying domestic power to sockets. The idea seemed to me a little fanciful at first and the thought of high voltage and data mixing wasn't that appealing but as I thought about it a little more, it did all begin to make sense. It occurred to me that every home does have its own ready made network. It's primary use is to get electricity to every room but in theory, it could certainly be used to carry data if the current could be separated from the data stream.
Holding the adaptors it became clear that someone had in fact made the idea a reality - I had to have them! Looking at the box more closely, I could see that £5 had been written on the lid. I know for sure that they are worth a lot more than just £5 and to be honest I doubt if they have ever been used. I bought them instantly and was eager to get home so I could try them. As I drove home, I thought about how I could put them to practical use. I already have a good wireless network covering the house, well three in fact - each for a different type of data. But there is one gadget that would benefit enormously by being 'hard-wired' to my data network. We have a wireless media centre that streams video and TV programmes from a set of hard drives to our TV set. It's a few years old, but works very well. Not having a cable long enough and being loathed to drill a hole through our lounge wall, we have plumped for the wireless option but I've always been aware that the device can be hard-wired. Wireless is brilliant, but it can be subject to the odd stutter and this can be quite frustrating when watching a film.
I set about plugging in the adaptors, connecting data cables between the 'access point' adaptor and my data hub and between the 'receiving' adaptor and the media centre. A button on the front is all that is used to configure the devices and in a few minutes they were talking to each other. This was a very good sign so I tested the media centre and it worked perfectly, markedly quicker than it is on WIFI.
I always set out hoping to find something different, unusual and 'gadgety'. I was lucky today, doubly so as I was able to put it to really good use. I like days like this.
