Overview
Inspiration came from the Six Legged Groove Machine's portable rave party seen at Phreaknic, and the crazy steampunk contraptions people are building for events like DragonCon. Most of them look interesting, some even dispense liquid, but none of them seem to actually cool the contents.
Safety Improvement
After building the proof of concept, we learned that acidic drinks and copper don't mix well. The acid breaks off copper molecules into the liquid intended for drinking, and could cause heavy metal poisoning over time. We're going to shoot for stainless steel tubing next.
Materials
- 10Ft 1/4 Inch Copper Tubing (10Ft / Coil) (Home Depot, $12 for 20 ft) (DON'T DO THIS: Acids found in soft drinks are corrosive to copper.)
- 25ft 1/4" Stainless Steel Tubing (eBay, $35 for 25ft)
- Cylinder for shaping the coil (we used a can of baked beans)
- Plastic Drink Reservoir (1 per coil) (We purchased two 1 gallon Snapware containers from Target, $6/each)
- Plastic Coolant Reservoir (We purchased a square 2.5 Gallon container from Wal-Mart, $6)
- Drill and Drill Bits (For drilling holes in the plastic containers)
- Hack Saw (for cutting copper tubing)
- Fish Tank Water pump (DC pump with solar panel $20. 2.5 ft lift, 42 GPH. Also available is a 500 GPH bilge pump for $17. Way more than we need)
- 3/8 inch vinyl tubing (Home Depot, $4)
- Dry Ice (optional. Must be 18 to purchase. Wal-mart, $6/small bag)
- Alice frame (Army Surplus Store, $20-30 depending on whether you get the straps or not)
Proof of Concept
Worked well. Cooled liquids as expected. One thing we may have to watch out for is acidic drinks eating at the copper and creating a metallic taste. Can be easily reworked into a MK I version. Steampunk theme will be difficult due to the size and shape of the containers. Cyberpunk/Rave theme would work excellently.
Working Dates
- Began working on this at the hackerspace meetup, 9/17 - 9/18
