When I first read about this I thought it can’t be real but it is. The Raspberry Pi can be used as a stereo FM transmitter. It’s a pretty nifty discovery which uses a GPIO pin on the Pi to generate spread-spectrum clock signals and outputs FM Radio energy.
There’s no point in me rewording what has already been written so here is the explanation from the guys who discovered it over at icrobotics.co.uk… Read More
Using an off the shelf energy monitor you can graph your energy using Cacti. The monitor unit I’ve used here is a Current Cost ENVI. E-On were giving these away for free but they’ve probably stopped that now.
It comprises of a sender unit, with a single phase clamp sensor and an Read More
I thought it would be nice to perform some simulations using the familiar breadboard format without having to buy all the components.
There’s a few choices but this looks pretty good: https://123d.circuits.io
It couldn’t get much simpler than this example I made to see how it works but you get the idea.
