The Water valve.

I'll skip the fun times I'd had with water pumps and go to the current iteration of water system. I've opted to go with a gravity feed system at the moment using a large 1 gallon water jug. As I needed a valve for this, I opted to build one. As I don't have a laser cutter/3d printer, I opted for simple materials, balsa wood and epoxy. So this is just a frame that I've glued the valve to and mounted the servo in.

Current issue I've run into is the power requirement for an idle servo. As this is pretty high, I've had to figure out a way of powering it down while idle. First approach since I don't have a darlington array powerful enough to power it, I've opted for a ULN2803.  Currently still doing some testing with this setup, but have some parts on order that should save some space on my current breadboard setup(Until I find a better alternative or design a pcb for this).
