Radio Caroline: crank up the power!

Its happened, they've upped their power.

 

At last they have a new transmitter offering more power and better audio quality.

So its expected to improve reception, both in Caroline's target area and beyond.

Pi-Mote + RaspberryPi: checking the range

The RaspberryPi fitted with a Pi-Mote controller is a neat 433MHz remote control solution for switching mains powered equipment.

But to be of any use, the operation range must be sufficient to satisfy the requirements of your application.

So I set about doing a few range tests and have detailed my method and results here.

Hacking 433MHz Remote Controllers

With the introduction this week of the Energenie Pi-Mote control board, my first reaction was to reach for my credit card and place an order.

I don't know just yet what I'm going to do with it, but it seemed like a relatively cheap toy to play with.

While waiting for this starter kit to arrive, I remembered that I was given a 433MHz control kit earlier this year, but had not got around to doing anything with it.
