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)

Step 1: Coke Bottle / Water Bottle / Gatorade Bottle

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.
I'd use RTV silicone sealant instead of hot melt glue. Hot melt glue doesn't stick to plastics, or sticks extremely poorly.
You are right. That would be better. But keep in mind, the spirit of instructibles. Hot glue is not the best choice. But, Most people have hot glue setups more than they would have "The right tool". Thanks for your comments.
Clever! Thanks for sharing! =)
Neat and simple idea. <br><br>Well done.<br><br>Thanks for sharing
Thanks. I will be adding the instructible for a water proof switch shortly.
I'm impressed!
Nice Instructable! Thanks for sharing!
Thank you. My next one will be the water proof switch.
