I'm in the UK and have recently had a 10Kw wind generater installed.
You can see the generation output here;
Anyway, I am really interested in this project and getting a device to show generation & usage, and a green light to show when my electricity is free.
Are there any keen people out there that would like to build the device for me if I covered the cost of the hardware and your time for building it?
I would try to learn, but I really am useless with a soldering iron! haha.
Happy to solder a kit up and load the software on for you. Drop me an email to mark at markphelan dot net.
