Step 6Electrisical Stuff: Part 1 - The Bare Minimum
To drive the motor for the pump, you need 6v @ 50mA (approx. Just do what the manufacturer already has set up - 4 AA batteries).
Set up a simple circuit with your switch, but don't test your pump just yet. It isn't necessarily bad for the motor to run a dry pump, but it's not something you really need to risk.
Use electrical tape or some other method to keep all electronics dry. Do this before adding anything to your blood sac.
Now that everything is ready, it is time to test for leaks. Fill your bag with plain water, and screw the cap back on. Check it for leaks, around the whole thing. Then, turn the bag upside down and check the cap's seal.
If everything looks ok, test your pump out. I was rather impressed with how much liquid it actually could move.
