Hey guys, I was thinking of a DIY chiller for my nano tank, but not that I would really need it, just thinking out loud.
Anyone tried the following or have a suggestion? Would this even work?
Parts:
$34. Lux Win100 Heating & Cooling Programmable Outlet Thermostat -- http://www.amazon.com/Lux-Heating-C...Y8/ref=sr_1_12?ie=UTF8&qid=1334080584&sr=8-12
$29.99 0.14 Cu Ft Mini Refrigerator -- http://www.officedepot.com/a/products/299106/014-Cu-Ft-Mini-Refrigerator-Assorted/
$15.57 dosing pump "Aqua Lifter AW 20 vacuum pump" -- http://www.petblvd.com/cgi-bin/pb/TOE01137.html
$2. plastic tubing
$5. wall wart for the mini "DC" fridge to run on AC.
2-3 Emptied 1 liter soda bottles (whatever will fit in the mini fridge).
Total: $90. (less than $100.)
Description:
Run the dosing pump to pull in tank water in a large "loop" that pumps out the same tank water. Within the loop, coil up the tubing in the soda bottles filled with water. If possible daisy chain it with another bottle. Drill an entrance and exit hole into the fridge, put the bottles in the fridge, and plug the power in the programmable thermostat.
Potential Problems / Details:
1. Can the mini fridge cool enough to provide any value to the tank?
2. Can you have a temperature probe for the programmable thermostat, or can you find a model that uses a probe instead of the room temperature?
3. Do you need to use some kind of filter to prevent the intake from getting clogged? Maybe draw the water in from a filtered area such as a sump or skimmer.
One neat thing that I was thinking is sometimes Office Depot gives those mini fridges for fee if you buy x amount of office supplies. I know that admin at my last workplace got one to play with a while back for ordering $300 worth of paper (that the office needed anyway). Also, I believe you can use an arduino nano built with a temperature probe and a power relay for around $25-35.
Thoughts? Suggestions? Improvements?
