OK!!!! So you built this awsome electronic instructible that operates in harsh conditions or is submersible. It requires you to recharge the unit once batteries are discharged. It is a pain to take the unit apart to get to the batteries to recharge them. What is the simplest, most inexpensive way to achieve this??? Sure you can purchase a marine grade type enclosure..... but at what cost...... I have come up with an awsome solution.... Please follow me to get the answer..........
Tools: Cutting device to cut plastic, High Temp Hot Glue gun, Canned Air (optional)
Parts: Charging port (user determined), Coke bottle, gatorade bottle, water bottle, etc.... (what ever works for your needs)

I'm sure you have a bottle of some type in your fridge, or you're sipping on something right now. I used a coke bottle for mine. I built a small pool craft using a bildge pump, battery, switch, and charging port. I had to figure out a way to waterproof the charging port.
1st. Take a Coke bottle and cut the top off.
Well done.
