If you have ever set watching TV or reading and looked over to see your drink is all "warm'" well no more with Chillanator.
The total cost of this project was about 10.00 dollars US.
The Peltier chip was 7.00
The fan was one dollar and the LEDs just a few
Step 1: Order the Stuff
I chose to make my own heat sink from scrap copper and brass.
If you are astute you may have noticed the Peltier mounted to 1/2 inch copper, this is not required or important, a friend offered a chunk and go thought I'd give it a try.
I plan to make a new instructable using two chips and will discuss heat removal then.
The fan was from electronic gold mine it's a 12 v squirrel cage design, I think this is far more efficient than a muffin fan because it blows air at a higher rate of flow
Step 2: Build a Box
To make the leg cut outs I screwed the two sides to a scrap of ply wood and drilled a hole using the center seam as a guide
Step 3: Some Time Savers
Since I discovered an old switch that required more than a round hole I hung the box over a clamped piece of ply wood this prevents tearout and allows you to put pressure on the bit with out breaking the box.
I recommend building your box a little larger than you think is required because stuff almost never fit to perfection
Step 4: Make a Logo
Sorry I can't post a link I'm working on an I Pad.
Just do a search here and the process is explained quite well, to cut costs I ripped a salvaged overhead fan blade made of clear plastic, if you decide to have a trophy shop cut your design don't polish the edges until it's been lettered, smooth edges slip out of the engraver.
Step 5: The Power Supply
Judging by the temperature of the transformer it's safe to assume it's pulling near capacity of it.
Step 6: Final Thoughts
I strongly suggest buying several chips at one time, this reduces the fear of "breaking" your only one, plus after you experiment with your first one you'll want to use your new found knowledge to make a better project.
I used JB Weld to secure the chip to the heat sinks, some brass powder was mixed in to help conductivity.
