I have been building a Steam Punk styled Solar Controller for our van since we moved to our house in Queensland two months ago. It is made from recycled antique hinges holding together three blue gum wood chopping boards. It allows you to direct power from a solar panel to a deep cycle battery. This can then charge my camera battery and power my laptop. I can then shoot, process and upload to the internet with 100% solar power resulting in Fossil Free Photos next time I am on the road in Australia.
The next job will be to attach a 150 watt solar panel to the roof of our van. Until then there is enough light coming through the window to power our music system.
