This is an Instructable for an air tank that can be used with lego pneumatic elements for powering robots without continuous pumping. This goes along with my pneumatic snake, and my bike pump adapter instructables.
Step 1: Materials
- A plastic bottle that can hold pressure. I used a carbonated water bottle. Anything should work as long as the top seals.
- A tube that your pneumatic hoses will fit over. I used some hard plastic ones that come in some lego sets.
- Glue-preferably something thick. I used hot glue.
- Something to make holes in the bottle cap about the size of the tubing. I used a drill but any sharp pointy object will work.
