Wine Pump and Project #2

After letting the wine bottle sit for 120 hours we took a look. While we didn't have any way to measure the exact volume of the balloon, it looked like the size before we pumped out the air. When I pressed on the air release it make some noise, but it was fairly brief. So the pump does does a decent job of removing air, but not of keeping new air from seeping in.

Even after switching the cap the battery charger still wasn't fully charging the batteries. So I put an ammeter in series with the batteries and found they were only getting 0.4 mA - about 1/1000 of what it should be. So I looked back over things for a bit and found that I had put the pnp in backwards. Doh! Well now it is in the right direction and the charge current is 430 mA. Much better - hopefully that will do the trick.
